I got a used q9550 a few weeks ago and 2 days ago I started overclocking. I would raise fsb in increments of 10 and run p95 for at least 12 hours with no problems. I didn't have to raise any voltages or anything. when I got to 383 fsb the pc froze during bootup, so I raised vcore to 1.36 and vdram to 2.0. Under load core 0 shot up to 75 degrees, so after a few minutes I shut it down. This morning I turned on the pc and went immediately into BIOS and turned fsb down 10 or 20. Windows started, but after about 10 minutes the screen went black and I shut it off. Since then I can't even get it to post. I reset cmos, I checked to see if any RAM was loose. I don't see anything wrong. I hope I didn't fry my cpu or anything else. Not sure what to do. My specs:

ASUS p5q pro turbo with modded BIOS
q9550 cpu
8gb (4x2) crucial Ballistix ram
Antec 500w psu
NVIDIA GeForce 9800 gt video card
Razer Barracuda soundcard
Xigmatek HDT S1823 hsf

Thanks!

you have gone about the correct method in overclocking but your specs says your running an antec 500w power supply. You should be running atleast a 550w psu for that system and overclocking that system even without raising the voltages will be pushing that power supply over the edge and may have already damaged it.

Go into the BIOS and post your voltages and temps if you can.
