XP Home SP2 going to sleep and will not wake up

I had 2 customers call today with the same problem. The first system was an HP, and the second system was a Gateway. Both system are running XP Home with SP2. They both had the same problem. When they are working on their machines, it looks as if the computer went into sleep mode and will not wake up.  The only way to get it back up is to hold the power button in till it restarts.  I had them turn off all power saving features in XP and also the screen saver. I just thought it was strange that 2 people with different machine are having the same problem. Does anyone know if this could be a virus?

Have not heard of a virus, although it i possible.
Also check the BIOS power options.

I would disable hibernation on any desktop machines.

I hope this helps !
just coincidence imho

Working in a computer repair shop, see this on a fairly regular basis.  In the situations I have seen it, the following fixes have worked:

1.  Change the PSU - for some reason a PSU on its way out can cause this

2.  Change the monitor - not the obvious, but messed around with settings/psu/ram the other day to find that the screen was faulty.

3.  Change the video card/motherboard - Try using a different video card.  If onboard graphics, either change the mobo or add a video card for testing.

These are the solutions I would put forward, having seen this problem on many occasions.
