Video card/Monitor

[doppleganger]

At times when rebooting my machine instead of getting the Windows XP splash screen I'll get color bars. Is this an indication of bad video card or monitor/connection, drivers, or something else?

It's probably the video card. Try replacing it temporarily by running on onboard video( if u have it) for a few days and see if you still get the same problem. If you don't, chances are it's the video card.

whats really weird is, its not all the time that it does it, and under normal conditions (once the PC is loaded) everything works fine. Games play great, etc.

This could be caused by a marginal video driver too

"marginal"?? What does that mean?

My opinion...

Software thought: Are you using beta drivers?

Hardware thought: Take a multi-meter inside...power supply seems unstable.

Oh let's see... something that works, but not quite like it should.

orko1978 thought's are good too.
You may not know what a multi-meter is, so you could try another power supply, as well as telling us what are video drivers you have installed

never hear of "marginal" drivers, haha. Beta...of course; however not used.

vidoe driver used:

I'll give the multi-meter a try since swapping the PSU may not be conclusive for the fact that it doesn't happen all the time.
