Yet Another Plea For PC Help- Boot Up Problems

This problem started a few days ago and has progressively gotten worse. I was on the internet, doing normal internet things when all of a sudden everything on the screen starting freaking out and shaking and I couldn't do anything. After I turned the computer off and went to turn it back on all I got was a black screen. Tower was on, monitor was on but screen was black where the Windows XP logo should have come up.

Eventually I got it booted back up, and the problem persisted after a few minutes of being on, the screen would go crazy. Eventually I figured it was a virus so I did a system recovery, and that seemed to fix the problem. Skip ahead to yesterday I went to turn on the computer from being shut down, it started again and no matter how many times I tried I couldn't get it to boot.

So basically I've got a computer that turns on but doesn't boot up. The fan runs endlessly, and sometimes it doesn't even turn off after I've held the power button for a while, I have to turn off the power strip to turn it off.

Any idea what could be going on?

Thanks in advance

Sounds like overheating to me. Either the CPU or video card. Have you opened up the tower? Do that, turn it on, and see if ALL the fans are running.

Also while you're in there, if you see any dust collected around the fans and heatsinks, get a can of compressed air and blow that stuff outta there. I've seen some gnarly dust buildup in heatsinks that would cause overheating issues even with the fan still turning.

Fans are running, blew out most of the dust. Will have to get some compressed air to make sure I got all the nooks are crannies.

Re: Yet Another Plea For PC Help- Boot Up Problems

I would say its your video card causing the problems. Have you installed any new drivers lately? Try onboard video (if you have it). Also try removing the video card and use an older one (if you have it) One thing to try is after the POST screen and before where you would normally see the XP logo hold down the F8 key this should (key word there) give you the option to boot into safe mode and you can start troubleshooting the problem (video card)

It's not overheating otherwise your pc would lock up/or shutdown and the next time you turned it on it would POST then shut down and keep doing this until your cpu cooled down enough to actually work and it would be an endless cycle.

Could be bad RAM.

I had my computer power up but not get anything on screen until narrowed it down to the RAM. One stick was causing the problem, stopped when I took it out.

But cleaning your computer out is a good start.

Might also want to check all the connections to see if they are tight, ram, video card, power supply etc.
If you can boot, see if you can go to safe mode first.

I had an issue like this once. It turned out to be a bad capacitor.

You didn't mention it but does it beep a few times at startup? Could possibly be the memory sticks. Open the box, pull & reseat the sticks. Good luck!

Sounds like what happened to me when my power supply went bad.
