suddenly my PC turned itself off a few nights ago. I started it again and it seemed fine.
Now when I try to start my pc it makes an odd sound that seems to emanate from on the motherboard somewhere. it seems to be almost a clicking sound. when it finally posts it emits a beep about 2 or 3 seconds long and then appears to be running. During the initial startup phase (before the post) my monitor just states "no signal".
I pulled everything off the board except obviously the Processor and it still does the same thing. I think i have it isolated to either one of the following: Power supply, CPU or MOBO.
Specs are as follows;
DFI Infinity NF4 Ultra 2 AM2 M.board.
AMD 3800+ AM2 CPU.
Corsair RAM CL5400 (2 sticks 512) dual channel.
LiteOn DVD-DL drive.
EVGA 512MB 7950GTO PCI-E video card.
thats mainly it. I may have missed something.
I just wondered if anyone had a similar experience.
oh and i tested the monitor on a diff machine and its fine.

Using a multi-meter you can check the voltages coming from the PSU. CPU and MOBO are going to be harder unless you can swap parts out easily. MOBO should beep at you when the memory is not in the system. Have you tried running one stick of memory at a time to test to see if one is bad?

I will test that and see if thats the issue, my gut feeling is that its one of the three items CPU mobo or PSU.

Thanks.

Hopefully it will give you a clue as to what failed.
