Hi have been working on a computer, here is the approximate spec:
AMD athlon 2800+
1GB ram
DVD rom and CD writer
80gb HDD
Creative sound card ( a fairly decent one)
Nvidia Gforce FX 5950 Ultra
New 500Watt power supply
I have a problem in that when any sort of intence graphics take place, it switches off, and will not turn on until it is unplugged and re-plugged into the mains.
For testing purposes I have been using 3d Benchmark, and When I run this it inveriably shuts down before the end of the tests (normally on CPU Test - is this Necessarily relevent?).
I have tryed the Video card on another machine and that works fine.
I have changed the power supply, no joy.
I have just re-pasted the heatsink to the processor as I thought it was loosing contct (the old paste was very dry).
The problem still persists, and whats more, nothing seems to be getting overly hot. I have felt the cpu heatsink and the graphics card after shut down and they seem ok, Also when I reboot and look at the temops, the CPU is at about 120 degrees whic doesnt seem exccessive does it (concidering my P4 runs at about 175 - and by the way, is that ok?)?
If Anyone has any assumptions on whtat the most likely cause is, I would very much appreciate it..
Thanks in advance for any help.
