It would seem that you have some additional problems. The system should not have rebooted from a game crashing. Lock up yes, blur screen yes, reboot no. The game is approved for xp, and not an old game that happens to run on it? It could also be related to your PSU problem, or it could be an issue with another part getting ready to die. Is it still under warrantee? If so you might want to pack it back to where you bought it and let them have a look. IIRC, that is the brand that London Drugs carries?

The system not being able to find the drives is not good. Seldom do the cd and hard drive roll over at the same moment. You might take a look and see if they have anything in common, like being on the same power lead, or the same ribbon cable. Check to make sure a jumper didn’t fall off. Then you might pull the power from the cd and see if it will boot. If not then plug is back in and unplug the hard drive, put a bootable disk in the cd and try to boot it again.

You can check the PSU with a VOM, just turn the system on and pin it out.

The last thing that comes to mind is, if the cd reader and the hard drive are on the same ribbon cable, and the board has two IDE controllers, switch it to the other controller.

That’s all I can think of at this time……
