    Yes, is there any way to undo this? I'm assuming by your response I'm pretty well screwed...

    if it wont let you into the bios screen, on your Mother board there is a 'clear cmos' jumper, and/or a cmos reset button. do you know where it is? or have your manual?

    I'm affraid people other than myself have lost the manual, there are two buttons on the motherboard however, one seems to restart the computer while the other will turn it off of held down, and back on once off.

    okay, look closely at your motherboard and read the ,make model number off it

    ...this is why i wanted you to use software to start

    There's a bunch of numbers... How many digits is the number I'm looking for? Right now I see something that says jp2 - clear CMOS 1-2 clear CMOS 2-3 * default.

    I'm seeing "e1/e2" above where it says Dell on the motherboard too.

    okay, you need to remove the jumper pin from 1,2 position to 2,3 position...wait 15 seconds and then put it back to the original position. that will restore the bios to the default settings.

    Ok, that fixed that, now I'm getting a "please re-enter CPU settings in the CMOS setup"

    in the bios find the key possibly F6, for default settings or values. then F10 to save and exit

    Did that, I'm presented with a new problem now. A lack of an operating system. Vista came with mycomputer but I don't own a disk. So now I really am phoqued. Before I attempt it, would installing XP be ok? Or would that not work?

    Scratch that, I found my folder for my computer! It also has a disk with vista on it so it's all good.

    it would wipe out all previous data.

    if i had seen that post sending you into the bios having never done this before, i would have put the brakes on it. Thats why i linked you to the OC article first, and looked up the multiplier issue and linked that article, and linked you to software to OC. if the OC is unsuccessful with software, it restarts and reverts to stock settings. Things can go awry fast in the bios.
    have you attempted a restart again? or just the one time?

    BTW*** it seems that the 630i has a long history of problems, particularly with SLI/crossfire

    I'm hoping at this point I can start my computer up from the disk and not lose all ky Data. I don't know what to expect at this point.

    It sat there for the last 30 minutes. I don't think it's gonna work.. I'm gonna restart it and let it sit over night. Worst case senario I have to reinstall everything. Sucks but oh well. Least my computers up again. Believe it or not, I still wanna try OC again. If you feel you can put up with me some more! Lol. Good news is, if I mess up again I know how to fix it now.

    If you get the machine up and running then you should be able to get a bit more performance out of your C2Q 6600. I'd say 3.0Ghz without changing any voltage or cooling should be acceptable. The processor has a locked multiplier which means you can't change the x9 to anything else, even if the BIOS lets you it won't work. So the route to overclocking is increasing the FSB. This can lead to stability issues since many things run from a clock derived from the FSB clock. For instance the PCI clock, not sure it affects PCIe but you shouldn't push your FSB too high to begin with due to its indirect effect on the graphics card(i.e. overclocking the FSB will also mildly overclock the PCIe frequency).

    As others have suggested a 5Mhz increase at a time and some testing will let you find the highest stable speed. 3.0Ghz at a 333Mhz FSB with your PC6400 ram should not be a big problem to achieve.

    Hope you get the machine up and running. Maybe worth getting a new OS. 32bit OS will only access ~3Gb of your 4Gb of ram. Maybe worth seeing if you can get some sort of Vista to Windows 7 64 bit upgrade.

    hellokitty[hk] Hello, nice to meet you! Posts: 4,378   +127

    Wow, sorry about that.
    Software has never been good to me. It's in fact never worked properly and usually results in crashes. For me, BIOS is pretty simple, and usually quite safe...since resets usually fixes anything you possibly screwed up via BIOS.

    3ghz is in fact 333mhz FSB.

    Doh, my mistake. Did run it at 300Mhz for a while but am running 333Mhz now as in my system details link.

    Update : After Fixing my computer the first time, I managed to crash it again, so im doing pretty good considering that for the second time in 2 days I managed to revive my computer. As far as not crashing it to begin with, I need some work in that area, lol.

    It crashed because I did not follow the advise of bumping the speed up 5mhz at a time. I simply cranked it up to 333Mhz resulting in the crash. (oops, my bad!)

    So perhaps one of you guys can help me with a couple new issues i'm having. I made a thread here
