My Specs:
Quad Core Q9550 OCed @ 3.83GHz
XFX GTX 260 core 216 Black Edition (712 core / 1215 mem)
4GB Corssair XMS2 DDR2 800 (4-4-4-12) 2.1 volts
EVGA 780i Mobo
700w OCZ GamerXStream PSU
320GB Hard drive 16MB cache 7200RPM
Sound Blaster Audigy SE
Windows XP

So after doing the overclock on my CPU I have left the voltages on auto. The CPU has automatically increased to about 1.35v and the FSB to 1.3v. The computer seems stable while playing, but I am having boot up issues. The computer sits with a black screen for about 45 seconds before it will post. Then I get a safe mode warning. This does this regardless if overclocked or not. Even on default settings still. I have cleared the Cmos, updated bios, you name it. So I am wondering if its a FSB issue. The error code on the board for the 780i is 21 which is a power management error. I got a new PSU and still the same thing. Got new Ram, GPU, even switched out my mobo 3 times.

Do you happen to have a western digital hard drive, because after post if you have the jumper in then it will take awhile to boot up, it will just sit there for a good 20 seconds. Its because if your HDD is the master with a slave you don't need the jumper in, not sure if any other HDD manufacturer is like that, but WD is.
