motherboard has power but wont turn on This is a topic that many people are looking for. bluevelvetrestaurant.com is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, bluevelvetrestaurant.com would like to introduce to you FIX A COMPUTER THAT WON T POWER ON. Following along are instructions in the video below:
“You guys got another video here for you in this one. We re going to to be taking a look at how we can fix or diagnose. A dead computer may not be getting no display on the monitor you can t get no power to your computer. And we re just going to go through some steps that you can take to try and resolve this issue.
Now. This is a new format that i m thinking of doing. Which is basically me free talking to you rather than you listening to me. Doing a tutorial sort of based thing and we re going to be talking about stuff that you can do to fix things.
And it s a little bit more easier for me to free talk. But obviously you re going to get a few mistakes with creaking floorboards and the odd mistake from the speaking. So that s as long as you re happy without then that s fine. But let s go through some steps that you can take to fix this now depending on whether you ve got money to burn or whether you re on a tight budget.
And you ve got an old computer or a new computer. It s going to all depend on different factors of what you ve got ok so just go through some basic things that you can first do ok. So as a home user. The first few things that i would do is visual open up the side panel and then smell inside and see if there s any burning smells that you can smell ie burning from the graphics card burning from the power supply they normally get often nasty odor when they let go and it s the components that burn out inside and you normally get a nasty smell.
If that is the case base nine times out of 10 is going to down here. Where the power supply is and you re going to get a nasty smell. Ok. So that would normally be a telltale sign there so let s move on to something else that you can try yourself so.
Let me just push this back here. I m going to push this back. So you can see inside a bit more clearer. So what we re looking for here is the power cables from the power supply here make sure they re plugged in ok.
Make sure they re right plug being pushed in all the way if you ve moved house or someone s had the computer or addicts sitting around for a while they could ease loose people moved about and they can shift loose. So make sure they re seated all the way home make sure the power1. He s pushed all the way home as well to make sure that that s working the next thing that you want to check for if it s an old computer is blown cats especially around the cpu area here and then around the motherboard your cds. Little cats.
Here. The more modern ones are sealed. And they ve got less chance of letting go because they re more quality platinum and gold type caps here. Nowadays on older computers.
They used to let go quite a lot. And if they are spewing some white fluid out or they may have dried out inside. Then it s time to replace the board or replace the caps or upgrade your system. So let s move on to what else could go wrong here.
Make sure the memories pushed right home. And it s definitely pushed in and inserted correctly another cheap fix is replacing the cmos battery. If it s an old computer..
The system won t boot. If you ve got a dead cmos battery and you want to replace that you need to replace their normally duracell or something not they can replace those and they ve got a life expectancy depending on the quality. But sometimes. 10 plus years so that s what i would do first off for cheapness.
Another thing that you can do is check your power cable. Which is this cable here now. This is the first thing that i check and sometimes these breaks sometimes people having them in cabinets. In it and it s bending over like this and this part breaks inside here.
And you ll get no power technician will come to your house. It will charge you and sit around and they have charged you an hour s time and they ll say your cables gone or you may charge a bit longer and then dress it up a little bit sometimes they do especially if they re bad. No work and next thing you know you re getting stung. Quite a lot of money for a silly little kettle lead.
Which we called in the uk. Which is probably a couple of pounds or a couple of bucks in the us. So check those out okay now if you don t have one of these it might be will apply one if you ve got another computer in the house. Then take that out and plug it into the computer.
That s not work as see whether that fires up the next. Cheapest thing that you can do is to check the power switch on the case itself. Now. This is a common issue.
Let me just tilt this over just to show you so not on whether you can see that but this power switch here sometimes these break especially on older computers. The switch. Let s go the micro switch breaks and it s not powering on the computer. So what can you do to fix that or test.
It well that s pretty straightforward if you have a reset switch here. Which this one does what i would do as a tech. I will go into the computer here and i would look at the area here that we just push that back and go down to where the connectors go to the motherboard and i would replace the reset. Switch over to the power switch.
And use the reset. Switch as the power switch temporarily to see whether that powers on if it doesn t have a research. Which you can use a screwdriver to jumper across the power switch to see if it bypasses this switch and it will power on the unit. If it doesn t work then obviously then it s not that that s not the issue if something else.
But if it does work then you know the switches failed. And you can either continue. Using the reset. Switch.
As your pal switch or you can just buy. A new case. So that s the basics out the way which you could try it it s not going to cost you a lot of money and i would definitely try those out lights on the motherboard is another sign that you want to look for..
Which is so if you re powering on this system look for any activity. Light on the board. There ll be like a little light or if there s no light on there there may be numbers coming up from the bias. If it s a newer machine.
See if there s any other activity does the fans start to spin. And then go off there s the cpu fans start to spin and then switch off or if you ve got a closed a loop wall cooling system like this this may be a problem. There s loads of reasons. Why things don t power on.
But if you get no power whatsoever to this then it s possibly going to be related to the power supply. So then let s move on to the power supply. So let s go on to something a little bit more juicy. The power supply what you need to do is swap it out with a new one so that s going to be a bit more costly.
But that will be the next step. I would take so go buy yourself a power supply pretty much like for like if you ve got a 300 watt power supply in there. Which is like an old dell or something like that then you may want to check to see whether the power supply is going to fit your system. Because sometimes dill can be a bit weed with some of their power supplies.
And well fit in some cases. So check all those out first you may want to buy secondhand one on ebay or something like that i don t know whatever your financial monies like i m not too sure. But basically try and get a decent power supply a lot of people always skimp on power supplies. And you ll get people online over selling stuff as well.
I mean don t get me wrong. I watch a lot of youtube channels. And some of these channels are just pumping out stuff with like 1200 watt and 1500 watt power supplies you don t need that amount of power. I know jc says and linus tech tips do that sort of stuff.
That s because it s interesting for people to watch. And i ve never seen that sort of power supply before so it s just companies. Chuck and chuck them out. And for a review in the course.
They put me into systems that they don t really need to have that in there you don t need a super power supply to run a system you know best go for something. That s got a couple of under what spare just in case. You upgrade. And that s pretty much it and get a decent brand new one gold.
Certified. As you can see here 80 plus bronze. Certification or silver or platinum or whatever. It is you want to go for just make sure you get a decent one okay with enough power to run what you want to do another thing that you once you ve tested that out if you still get no joy with that then you need to determine what else is going on with a system.
I would remove any sort of cables from the cd rom drive if you ve got a cd rom drive up here i haven t got one. But if you have then remove all the cables and power to those and then sort peripherals that plugged in there that could cause problems and then try to power on just in case. One of those have let go i ve seen broken cd..
Rom drives stop in the system power on or both up you normally get some sort of display here. But it s you know there s tons of reasons. Why things happen so that would be the first thing and then the next thing you need to get down to is whether the motherboard has failed or the cpu has failed now sometimes the graphics card can let go and it can do some funny stuff and again check your power supply and your feed to the graphics card have you got enough if it s a new build that s another different type of scenario whether you ve got enough power to run yems to run the graphics cards that you ve got maybe you ve got two graphics cards in here. And you haven t got enough power.
And it won t work properly you can get that reboot loop. Where it just starts up shuts down starts up and shuts down. It just hasn t got enough juice to get that going. And that s a quite a common thing to happen on some of these builds and that s when you re going to step up to someone in bigger power supplies.
So that s getting off topic. A little bit. So another topic. But check your ram and make sure the ram is but if you ve got four sticks.
Around here or two sticks of ram or whatever. It is you ve got in your system. Take it all out and leave just one stick in there and see what happens and then change that stick over with the other one and it just keep one sticking at a time until you ve gone through all the ram that you ve got in your system. And see if it boots if it suddenly boots.
You know you ve got a bad stick of ram and you now know which one it is that s bad and replace it that s a pretty easy way to test. Now. I see a lot of people talking about testing memory with mem test. And doing this sort of stuff.
It takes a long time to run tests on mem test you have to run certain cycles and stuff. Like that. And you would have to run at least eight passes in my opinion to get a really good test result on that and even then you re not sort of hundred percent. Really and that could take 24 hours 48 hours depending how much ram you ve got there so swapping.
Out is the quickest and easiest way to test a go starved. Cheap and then work your way up to the more expensive stuff until you get down to the motherboard and the cpu graphics card cpc technicians they ll have a graphics card lying around they ll have memory lying around that s known good to test and it won t take long to test that out where as you re trying to do it on a cheap and it can cause you more money in the long run. So that s another thing you can get testers for power supplies. And you can put the pin inside the jumpers and i ve showed you how to do that in previous videos.
But personally it s normally left will alone for that sort of thing. I would go and get yourself another power supply and go down that route rather than using the power supply testers. There alright and if you want to do that as a cheap option. I will leave an image up on the screen a link in the description.
So you can purchase one of them they re probably around about 10 pounds 15 pounds. And you can buy one and plug it into this and if it lights up like a christmas tree. It normally means that power supply is pretty good. But i have seen intermittent issues.
Where that is lit up like a christmas tree and said. It s good and it s not good and this our fault. There..
And there s not enough power going through and you ve got issues that could be bad capsule. All sorts inside here as well depending on harold. The system is so moving on to the next step again. It s very unlikely that the hard drive is failed and you re getting no activity from the motherboard or anything like that so if it is dead.
Then you re now going down to the motherboard and the cpu and unless you ve got a bench with an identical socket to test the cpu. It s very unlikely that you re going to be able to test that now but they their cpu can fail. But it s unlikely that it has gone it s more likely the motherboard that s let go. But i have seen cpus fail before but on the grand scale of things.
It s normally motherboards out we cpus when they fail and it s normally on i can t give you an exact figure. But are fixed. So many computers over the years and i would say it s minimal when it comes to cpu failure and massively in favor of the motherboard. So you can choose to replace the motherboard.
If it s an old motherboard ie an old system then do you really want to go down that route do you want to upgrade to a newer computer. Some people set in their ways. They don t want to let go their old system they pay 1500 pound for it 10 years ago. And they still think it s worth 15 underpin.
When it s worth absolutely nothing. So it s trying to educate people and try to get them to move up and go for something newer technologies moved on so much nowadays and you can still build systems for a pretty reasonable cost so it just depends on whether you want to replace the motherboard or go with a new build it s in target. 2. You may be able to get 2nd mm one on ebay or so if you re really tight for cash.
But that s pretty much it and then once you replace that you should be pretty much good to go so there the scenarios on how to fix a big computer. If you want to see i wish i could actually show you step by step taking stuff out. But that would be time consuming. And it will be difficult to do live and edit and stuff like in plus.
You would need a dead computer in the first place so that was where where i d be started that s what the sort of scenario. What i would sort of try to go down and fix. The graphics card again we didn t talk about that too much wind that graphics card has failed sometimes that can be issues you can remove the graphics card. If it has onboard graphics and it s on the cpu then stick a graphics card in a cheap graphics card and see if it fires up pretty much that s about it for this one really they re the steps you can take to get you back up and running.
