Something resetting my OC settings in vista!!

Here's a strange one, at least for me. I have re-installed vista 32 and flashed to the newest bios on my asus p5k. After installing everything I went into the bios and set my overclock settings to what I new worked in the past. Everything was fine, CPUz showed my OC was working fine ran crysis benchmark for a while and everything was going great. I restarted a few times and tweaked the settings, still everything was fine.

Then I tried sleep and hibernate mode, neither have ever worked with my set-up; this is when things stopped working. After re-starting my computers from the failed sleep attempt my bios settings in CPUZ were showing the default settings. I check in the Asus software and again, default settings. My ram was even running slower than default and with worse timings! I tried everything that I could think of(or look up on the internet). Here's the strange part, I can OC my ram and increase the timings with no problems, CPUz shows the changes in Vista. As soon as I OC my CPU and FSB and boot up, everything goes back to the defaults!! GRRRR...

As a note I know that the bios settings are fine, It even shows them at the post screen...but after vista starts up they drop back to default. These settings worked fine until I tried sleep mode, could be a program or Vista setting change that I'm not aware of...shrug, I've tried checking the Vista settings though.

just try reset your bios and do it again.did you reset bios after a bios reflash?

Sucks....

One of my boards seems to lose it's bios setting every time I was shuttong off the main breaker to do some electrical work around the house.

Thats sound like a dead cell battery in your mobo. If the computer loses main power and loses it's settings thats the problem.

have you already updated the bios to the latest?i mean as i can see its not only you that has the problem others have as well.so gigayte should well aware of that.
