Hi, I have a system that I built about a month ago, and its been going pretty well until about 10 minutes ago..I was running 3dmark2k1 in contiunous looping for about 10 minutes, and i went to talk my brother and when i come back in the system just shut off, just like if you pulled the power plug out...now when i try to boot nothing happens at all. if I pull the power cord and put it back in the PS makes a click noise, and the mobo's led light turns on but my cpu fan doesnt start, my HD doesnt start, nothing. Now im not sure exactly why this is happening, im thinking its possibly a bad PS, because one of the problems ive been having with this system since ive built it is that it would freeze on boot, and generally not start up perfect until its been powered on for atleast 10 minutes...Does this sound like a power issue possibly? I mean, i built systems before and even had cases where a dead CPU would not prevent HD's/cpu fans powering on, and same with video card...

Heres my specs:

XP 2100 B @ 2.2 ghz, temps generally at 51-57C
Radeon 9500 pro @ 317/290
Santa Cruz sound card
512 266fsb ram
40gb HD
floppy
3 case fans
400W[Maximum] PS supply-generic

please give me some clues!

not sure but being oc'ed and running 3dmark2k1 you may
want to try resetting cmos, and then look at power supply

Sounds like a fried power supply I see from your signature it's a generic one. This sounds like a good time to kick the generic habit and grab maybe a Enermax or Antec.

Those symptoms remind me of when I had a motherboard go out. At cold powerup, the cpu fan would spin a few times and the keyboard lights would flash. At warm powerup, nothing would happen. No beeps. New mobo fixed it. PS was fine. Good Luck.
