Windows 7: PC keeps restarting, seemingly at random, recent PSU and virus issues.

PC keeps restarting, seemingly at random, recent PSU and virus issues.

Hey people,

Recently my PSU failed and I replaced it.

Shortly after, I managed to get a virus which infected quite a few dll files. I've removed the virus now.

Since getting rid of the virus, my computer has been restarting itself at random intervals, although more often than not shortly after restarting. It can happen 4 or so times in a row, and once it's been up for 10 minutes it's usually stable.

I've read around and these are the steps I've taken (to no avail):
--> turning off automatic restart (so the computer goes to BSOD rather than restarting - though this has not worked, the BSOD does not show)
--> updating graphics driver

I was wondering if it's possible the virus I had has infected some parts of Windows which is leading to the restarting, or if the power supply is at fault, or something I'm not thinking of.

I'd really appreciate it if anybody could point me in the right direction.

Thanks.

The only way you will ever be sure, and the fastest way to get back going is a clean install.

Do you have the win 7 dvd?

Do you have a backup from before the problem started?

Hey zigzag, thanks for your reply. I do have the windows cd but not office so I want to try everything possible before going down that route. Tonight it isn't even booting at all, hearing some loud whirring noises from it too. Spoke to someone who knows a lot more than me, they suggested my hard drive may be failing. Would you agree? Thanks.

It could be your hard drive failing.

Run a disk check first: Disk Check

When you've done that, check the Event Viewer log to see what is going on:Check Disk (chkdsk) - Read Event Viewer Log

It's got to the stage where I can't get as far as my desktop, after logging in it just turns itself off.
Do you know of any ways I can test the hard drive before this stage? Anything I can do before the log in screen?
Thanks again for your help.

Hi Jarvey,

A Ken mentioned, a clean install is the best route to take. You mentioned you didn't have the MSOffice DVD? Is this an OEM installation?

Regards,

If a clean install didnt help chances are it is hardware. HD would be my first thought.
