BIOS keeps resetting every time I turn on pc.

So every time I unplug my pc and move it to another room, the BIOS reset. I thought it was the battery and I replaced it with another 3V battery and I still have this issue. Something else I noticed is the CPU fan speed is not being detected correctly. It will jump from 0 RPM to 3355555 RPM while the case fans run at 900 RPM.Also sometimes I will turn the computer on and it will sound louder, no screen, no lights on the back, nothing. I have to reset the hard power switch in the back and retry until it boots. Of course when it does, the BIOS reset yet again. Frustrating. Any idea what could be causing this?

Hmm....the only thing I can think of is maybe the flash the BIOS writes its values to is going, that or some other component of your motherboard is going. Sounds like a mobo/PSU issue (though from the sounds of it, it's more likely a mobo issue - I'd test with another PSU if you can).

I had the same problem but only if I turned off the PSU or unplugged the computer (or blackout or power flicker).

My fix for this was to buy a UPS and never turn off the PSU ever again.

Fixed the problem. After quite a bit of research of forum posts, I found out my CMOS jumper cap was missing. I pulled one of an old computer on the correct pins to save the BIOS and it worked!! Feels good to fix a nagging problem and also learn about something I didn't know about before...CMOS jumpers and their purpose.
