Graphics Card Problem, MOBO, or what?

I have a problem with a HP desktop PC HP 330DT. If the machine stays disconnected from the mains for at least two hours, on next boot up, monitor gets signal OK, but the OS (Win XP Pro SP1) fails to load with an error message that a certain file is missing and to repair, use the recovery CDs (or something to that effect). On attempting to reboot the system using the HP-supplied recovery and operating system CDs, signal to the monitor disappears completely. After that, the machine has to stay disconnected from the mains for two more hours before signal to the monitor can be obtained, then the cycle begins again.

At one point, I managed to restore the operating system using the CDs, but on the next reboot, the same problem re-appeared. I suspected the on-board graphics port to be faulty, so I fixed another graphics card (in a PCI slot). But the problem still persists even with this new graphics card. I tried replacing the RAM (DDR) modules but still same problem.

Any help is appreciated

Graphics Card Problem, MOBO, or what?

its not the graphics card that's causing the prob. it can be the mobo or the fan or the heatsink.. try to use the system while the chassis is opened and try to put a deskfan beside it and check how long the system can run without crashing.. if it runs longer then the problem is the heatsink or fan cause it is overheating that's why the system shuts down.. however if it shutdown same thing it can be the mobo that has the defect...
