Pc fails to boot

post #1 of 58
Thread Starter 
My pc is a year old now, and suddenly started to get slower over the last couple of days and then yesterday turned itself off twice during a 4 hour period. Now when I try to turn it on it starts booting and within 3 seconds of turning it on, it turns itself off.
I haven't changed anything since i've had the pc but it's suddenly started not working.
Help please.

Open the case and locate a small silver battery on the motherboard. Take that battery out for a minute and then put it back in, and try to start the comptuer. Post back and tell us what happened.

You will need to unplug the computer for that to have any effect!

I would check that you CPU fan is working. If it is, you should inspect your PSU.

My cpu fan only kicksin after it's booting as it doesn't really heat up. And if I open my PSU to inspect inside of it, I void the warranty. =S

Hi Lildrone,

The fact that its been getting slower is certainly something to take into account. Did you have slow HDD speeds etc? Was it only affecting games or just general usage?

It seems there is some odd Hardware failure though. Do you see anything on the screen when it boots up?

Maybe you can try to re-seat everything, make sure all the connections are good inside the case?

I would always recommend unplugging power to the system before messing with it. But the battery is there to save your bios settings when there is no power. So if the board is getting power, pulling the battery will not clear the bios. It might reset the defaults, but it wont clear it (which is needed for a corupt bios).

As for inspecting bios, you can check for burnt connectors, and if you have a multimeter, you can check the rails. Or you can buy a PSU tester...

Don't bother opening the PSU. There aren't really any servicable items in there. Plus you run the risk of giving yourself a nasty shock!
