Could a faulty PSU be behind my freezing/crashing problems?

post #1 of 20
Thread Starter 
Ok, hello, longtime lurker, first time poster here.

I've been going through tons of problems with my PC. All my specs are in my System Info.

So, to make a long story short, I started to experience problems with my PC since I uninstalled my virus protection software and installed avast!. Ever since that my computer has been freezing, crashing, giving me Blue Screen of Deaths and been rebooting at completely random (i.e when I'm playing a video game, my monitor just goes black and the PC boots itself, no warning message or anything.)

I have ran memtest86 and it has shown no errors in my RAM. I've also downloaded all of the latest drivers. I have BlueScreenView on my computer, and according to the software the cause of my problems is ntoskrnl.exe and xNtKrnl.exe.

So, we get to the PSU's part. From what I've read online, the PSU I have (LC-Power Green Power 560w), is a shotty product and may not have as much punch as the name would make you think. From what I've read online, a LC-Power PSU might even fall 200w short of the promised power.

So, what I'm interested in is, can a faulty PSU cause Blue Screening? From what I've understood is that it may cause freezing and crashing, but no one mentions anything about PSUs' connections with Blue Screens.

PS: When I started to notice this problem, I re-installed my Windows 7, but the errors still persist to exist. This is why I think it's a hardware related problem.

It's quite possible. Lack of quality, stable power to any one of a number of components has the potential to cause crashes and bluescreens... frown.gif

Basicly yea....... you bought a dud power supply.

If its not supplying the right amount of power it can cause all kinds of faults/errors.

You ideally need a new one.

A Antec/Corsair 500w can be had for not much money and they are both HIGH quality psu's smile.gif

If your PSU isn't providing enough power for your whole PC, it most likely wouldn't even start up at all. You should update all your drivers ASAP before you run out and buy a new power supply - only to find out that wasn't the problem in the first place.

Ok, an update, I got a new PSU, but the problems still exist. What could cause it if it isn't the PSU. Could it be my RAM? My GPU?

I've ran memtest86 and it still shows no errors in my RAM.

Are you running Avast on the reinstall? Seems like your problems started when you installed it from your OP.

Yes I have Avast. Should I uninstall it? But could just Avast cause all these problems (Freezing, random reboots and blue screens)?

The short answer is that all of these problems are able to be caused by the PSU in one way or another. I am especially convinced by the PSU you have.

I recommend replacing it now before things get worse.
