I went to fire up my desktop today after I got home and the fans fire up for about 2 seconds and then the machine goes into an endless reboot cycle every 5 seconds or so.

The video card fan fires up and runs. The cpu fan does not fire up and run. The CPU fan usually fires up briefly then shuts down and then fires up full time after a few seconds. The CPU fan briefly fires up then stops, then the video card fan fires up and then the machine just shuts down and restarts.

The case fan fires up and runs. I can hear the HD's firing up too.

I think something may be caput on the MB or the videocard.

Any help on this one? I'm stumped pretty good now.

I reseated the video card and both memory modules to no avail...
