I'm about to my wit's end here.

Installed a new mainboard, as I thought that may be my problem. It POST'ed fine last night, but I got a blue screen when I hit windows. Haven't figured that one out. Was too tired to last night.

So I wake up this morning, and the power light is on (i know i turned the PC off), but nothing's going. JUST the power light is on, and nothing else... WTF? Press power button, nothing happens. I dont get it... I went ahead and cleared the CMOS, re-checked the switch/case pluggies, and everything's as should be, and as it worked last night, but now, magically, this morning it doesn't work!!

HELP!

System spec's would be helpful. Sounds like a possible short. Try booting with the board out of the case on cardboard. Re-check cpu, ram seating as well as power connections.

Crazy question, but did you try leaving it unplugged for a bit then plugging it back in?

K8N Neo2 platinum
A64 3000+ Venice
tried two kinds of ram - OCZ Plats Rev 2, and Corsair XMS


And yes, I thought maybe a short as well, but I pulled the board out of the case and tried that way, and it did the exact same thing!

try to boot with one stick at the time, with just the cpu and the video card, try using a screw driver to turn the mother board on.

Try another PSU


valid thought, however i broke out the other mobo i was having problems with, and i am actually using it right now (still having corrupt memory problems, but it's not the memory)... PSU works fine, and voltages are stable.
