My computer has taken to regularly crashing. It does not come up with a blue screen, but instead normally freezes and then goes completely blank. Sometimes the graphics card also goes haywire, with the screen going a whole rainbow of colours. This happens most often at startup, and often I have to try to starting up 3 or 4 times to start up successfully. Occasionally during startup my computer claims that overclocking failed, although I have never knowingly overclocked it (I don't know how to). I have had my computer since 2004, my motherboard is a P4S800D and my graphics card is a Radeon 9800. I've run the standard cleanup programs (defrag/antivirus/antispyware) but there has been no noticeable difference, so I'd like a bit of advice now it's likely to need some more serious cleaning up.

Thank you in advance,

Richard.

Hi :thumbsup:.

First thing I suggest: Go to Device Manager, remove your installed video drivers...reboot and either allow XP to install the drivers...or you install them from the CD that came with your system/video card.

Your video drivers may be corrupt/damaged...and this will give you fresh ones.

Do I need to back things up for that?

I don't and I would not suggest it for this particular maneuver.

But...since you seem to already have known system problems, it would probably not hurt to back up.

Thanks.

My first restart after that seemed smoother, but my screen still blanked out on me for a little bit before coming back. It goes blank and comes up with "no signal found". Any ideas for that?

"No signal found" indicates that something is not facilitating a smooth video signal from the video card to the monitor.

First suspects: connecting cables, video card. Check that all connections from monitor to motherboard are snug, physically remove your ATI card and reseat it in socket. Then reboot system.

You might also check Device Manager to ensure there are no known driver problems.
