So a while ago a strange error started apprearing at boot, the computer would emit a series of long audio tones and a message telling me that my graphics card was not recieving power would appear. The PC would not boot. It went away after a while so I forgot about it. Fast foward a bit and now when my computer is being stressed (i.e playing a modern game) the catalyst control centre informs me my graphics card is overheating, though the system returns to safe temperature when idle or during simple tasks. The strange thing about this is that is began to happen only after all the computers in my computer room had been moved and the room cleaned, care was taken with the computers however and the only thing that changed after that was how the computers are plugged in. This overheating warning would appear at seemingly random times though with no real consistiency as to the circumstances.
Now It will help if I describe my situation and my computer:
Dell dimension 8400
P4 3.0ghz
1GB pc 3200 ram
PCI-E X800 XT
80GB SATA
The only changes to this system after purchase have been the addition of a 120GB SATA hard drive and a DVDR/RW.
My computer is situated in a room with three others, two of which are high end gaming computers, the fourth an older Dell. Unfortunatly all the computers (and anything else) are plugged into one wall socket. We have no choice in that regard, its an old house. There are long four plug adapters plugged into each other, that each pc is then plugged into. As I said there has been no real consistiency as to when this overheating occurs, others PC's on or off, room hot or cold. It would happen every now and then before disappearing for a while, though now its constant and I cant play anything.
So far I have updated my graphics drivers, cleaned the fans and heatsinks in my pc with a low power vacume cleaner, varified all the fans are spinning and that all the cable connections are sound. Most recently I have taken the CD drive that shipped with the pc, out, in order to improve ventilation. All to no avail. I have never overclocked the system. Im at a loss and any help will be very greatly appreciated (as I want to get back to playing oblivion!)
