Overclock problems - core 2 duo e6600 - GA-965P-DS3

So I built a computer with these specs:

-Enermax ELT500AWT Liberty 500W
-Scythe SCMN-1100 100mm Sleeve
-Intel® Core 2 Duo E6600 2.4GHz
-GigaByte GA-965P DS3
-OCZ Gold 2GB (2 x 1GB) 240-Pin SDRAM DDR2 800 (PC2 6400)
-Sapphire Radeon X850XT 256MB

Then I overclocked to 3.0 ghz following the Tom's Core 2 duo OC guide rather easily. Then about 2 weeks later, I was running TAT to check my temps, and I noticed it was back down to 2.4 ghz.

My mobo had reset the settings on its own at some point. Now when I go back into BIOs and try to OC again, even a tiny bit, my computer shuts down and resets to stock settings.

What I don't understand is that I turned off all possible failsafe settings to allow me to OC, so I don't know how it's resetting them. Anyone else having these problems?

hmm... you have updated bios? i dont personally have a gigabyte, but i havent seen this prob on forumz around the net..

what are your temps? normal? you have all power plugs plugged in? the p4 plug? is TM2 (the temp threshold thingie that resets clock if to hot) enabled? how the hardware monitor? is every voltage above what its spossed to be, is it fluctuating? especially on the vcore... have you tried the noobie overclock mode? meaning like 5%oc im not sure how gigabyte does it, i have "turbo", "NOS", "AI NOS", then "manual"

edit

when does it reboot? @post? @windows splash? in windows? does it even post...?

- BIOs is updated to latest
- Core temps at idle with stock settings are around 36-38* C. When I successfully OCed the first time, they were high 40s to low 50s idle, and around 60*C when fully loaded.
- All power plugs are plugged in
- Temp threshold is disabled

There is only manual or auto in the Gigabyte bios. Even the most conservative nudges in clock speed and voltages cause it to crash.

I loads the Bios/memory check screen, which will indeed indicate the new overclocked proc speed, then reboots. When the same screen loads, it indicates the original stock proc speed, and continues on to Windows as normal.
