BSOD, Boot Problems, Freezing Display...

Hey,

So my homebuilt PC was going strong for a month or two until the video card broke. I sent it in for repairs, and everything was working fine. Now I have another problem. About two weeks ago, I started getting BSOD's, the computer would randomly freeze, and sometimes the screen would just go blank (but the computer would stay on). I thought I had fixed it, until it happened again a few days later.

When I was having problems, sometimes I would try to turn on the computer and it would turn on for a second or two, turn off, then turn back on (sometimes nothing would appear on the screen and other times it would work fine).

Five minutes ago, for example, I tried to turn the computer on and nothing appeared on the screen. Now, I tried turning it on and everything worked fine.

One thing I've noticed is that it seems to BSOD most when I'm watching a flash video or using SyncBack SE to do network file transfers. That could just be a coincidence though.

Any ideas?

Thanks!

Since your video card was recently repair, I would suspect this component first. Can you swap out the video card with another one to determine if this is the problem?

Unfortunately, I don't. I also don't have another video card (though I should've said it was replaced, not repaired).

I'm also sorta thinking it is the PSU. Especially how it turns on, then off, then back on. Is there a way of checking without getting another PSU? The computer seems to be working now, but judging by the past, it's only a matter of days till it stops working again.

Hi, thanks a lot for the replies.

I also thought it was a PSU problem. I was especially convinced when I unplugged the power to the video card and the computer took longer (when I tried to turn it on) to shut back off, then turn on.

So I emailed the manufacturer and this is what they said:

The virus issue seemed kinda silly, but I unplugged the hard drive and tried booting to a Ubuntu Live CD. Still, I had the same problems (turn on, off, back on and nothing).

Any other ideas?
Thanks a lot for the help! I really appreciate it.
