Question about q9650 + P5B OC

well the new cpu came a day earlier than expected... imagine that!

To get everyone up to date here are my specs:
q9650 in Asus P5B with Xigmatek HDT-S1283 HSF
4 x 2Gb GSkill DDR2 800, 5-5-5-15
Quadro FX 1500 GPU
Antec 500w Earthwatts

1. First boot with default bios:
idle temps = 26-31 degrees C
idle vcore = 1.3v
load temps = 44-51
load vcore = 1.22v
DRAM frequency = 333 timings = 5-6-6-15

2. First OC:
FSB=360x9=3240
vcore=manual=1.2375v
DRAM=720(1:1) voltage=manual=1.85 timings=5-5-5-15
typical disabling of extraneous mobo settings.

idle temps = 25-31
idle vcore = 1.18 - 1.2
load temps = 41-47
load vcore = 1.12

Result: successful.

3. Second OC:
FSB=400x9=3600
vcore=manual=1.25v
DRAM=800(1:1)
everything else left as is.

Result: wouldn't boot into windows. When I went back into bios it wouldn't let me manually set the vcore anymore, 'auto' was my only option. I set the FSB back to 360, saved and exited and went back into bios, I could then manually set the vcore again. This booted into windows just fine as before.

4. Third OC:
FSB=380x9
vcore=manual=1.2375
DRAM=760(1:1)
everything else left as is.

Result: wouldn't boot into windows, but got a lot closer than the last attempt. When I went back into bios it wouldn't let me manually set the vcore anymore, 'auto' was my only option. I set the FSB back to 360, saved and exited and went back into bios, I could then manually set the vcore again. This booted into windows just fine as before.

Obviously there's some problem here as the q9650 shouldn't 'max' out at a 3.24 OC!! Any ideas?? During the third OC attempt while it was trying to boot into windows I got an error, something like, "can't load (or find?) the specified file: <windows root>\\system32\
toskrnl.exe". I had a couple weird windows issues last time I OC'd (see the first post in this thread), ie: I had to reinstall Avast antivirus and my ftp program wouldn't connect to my web server anymore (both internet related?) Anyways, I don't think these are the reasons why the OC isn't working right? Should I do a windows repair?

Thanks a bunch, your time is appreciated!
