    Hello awesome MDL members,
    I had a virus attack after which I performed a clean install of the windows 8.1 Ever after that, when I boot-up my PC I can't see any Bios hotkeys but on the contrary they do show up when I'm re-starting. Also the Time gets manipulated every time I do a shut-down. I Initially thought it might be because of the battery but then I noticed it getting out of sync every 1/2 hours even when my PC is running. All my apps have gone rouge because of this, my email grouping is destroyed and other strange things happening because of the time getting out of order.

    How can I resolve this ?

    Any help will be greatly appreciated.

    Thank you.

    Ok so it's settled I can't do it on my own. Can't even deal with a screw. I'll have to take it to a service center.

    Thank for the help Ed.:)

    try take battery and power cord out.. hold power button 30 secs to drain it.

    some HP's need the diagnostic partition made by the tool in support dloads of diagnostic section.

    I wouldn't think you'd need diagnostics to tell you if you always lose the time and date, the cmos battery should be replaced. Most desktops use a #2032 coin battery you can get almost at any store, Laptops are a different beast

    Ok. I'm gonna try that "from inside windows" alternative by MrMagic.

    That's what I thought but then I realized those hotkeys aren't showing on the boot-up as well as the time getting out of sync while PC is running. Resetting CMOS is just my guess, I'm not really sure what had happened.

    Does this not require any build information, Bios version etc? Is it just a fixed process of commands to accomplish it? I mean if I f**k it up, I don't even have any other PC to get back here and ask for help o_O

    Thanks Mod.

    No, it just resets it, haven't used it for a few years, but we got a load of locked BIOS laptops in the shop to fix, and couldn't do anything with them until the BIOS was unlocked, this did the job

    Think that program needs 32bit Windows to run

    Thank you mate for sharing these programs.
    I use to get into the computer at any cost lol to put my hands on that battery and pull it out.
    Hope these programs works like that as well.

    Edit:
    What happened to CMOS De-Animator v3? :eek:

    Thanks for the help MrMagic. I think this utility is not meant for the Laptops

    Could work I guess, if you can boot WinPE, in our case we couldn't boot from anything other than the internal HDD, which was why we had to wipe the CMOS to get control of the boot order

    I have only ever used it on Laptops, of course it's for laptops, you can remove the CMOS battery on a desktop easy lol

    Hate that sense of loss when a dev abandons or stops the evolution of a very useful program... :mad:
