    Hey lads.

    i have the below system and i'm having a problem where everytime i reboot my PC, i have to reset the Cmos to get it to boot up again.

    Is there any reason this would happen? It basically means i have to have it open all the time and am risking static problems by me and my girlfriend constantly having to stick our hands in the PC everytime we want to turn it on

    No it just doesn't post. The fans start and stuff but nothing happens.

    1. Go into Bios and for every setting on 'AUTO', change it to the correct fixed setting, i.e. for your CPU FSB and multiplier, RAM timings etc.

    2. Don't worry about static. Its not an issue when the whole thing is assembled and plugged in. All ground connections are grounded and everything is protected by its capacitance to ground. Static is only an issue with loose components.

    If by resetting it you mean attaching a jumper to pins, then you could just use a switch (connected to the pins) or alike if you never manage to solve it....

    You could also try upgrading the firmware version of your bios, you may just get lucky with that.

    Had this problem myself last weekend.

    Started happening after my memory Dimm stopped working. Re-flashing the bios fixed it for me.

    I agree. Try flashing the BIOS and you might just get lucky.

    Failing that, it could be that the CMOS battery isn't holding a charge. How long do you leave the PC off for at a time? I had a machine a few years back that had a similar problem. Turns out it was the battery not holding a charge. If I left the PC off for, say, 2 days in one go, then I'd have to reset all the BIOS settings.

    Yep!

    Or maybe you'll just kill your motherboard.

    Kill? That's a bit harsh, isn't it? Point taken though, it *could* end up worse.

    But if the PC's bordering on unusable now, then it may just be worth the risk...

    Its the process behind flashing a bios that puts me off.
    - The bios reads the program, puts the data it needs on the hdd, empties itself except for a 'note to self' saying 'see hdd'. Then on reboot it finds its instructions to itself to rewrite itself with whats on the hdd.

    Heres the big catch - This updating procedure will only ever work reliably if the data in the BIOS in the first place is all intact.

    So updating a working Bios will *usually* work, but using an update to fix a faulty BIOS relies on the updating instructions in the BIOS not being affected by the original problem.

    Incidentally - using any windows program to flash the BIOS is just asking for it. Always use the 'make boot floppy' option.
