Freeze and CMOS problem

August 7, 2011 at 15:10:24
Specs: Windows XP
These days, every once in a while, my computer freezes and sometimes, after the freeze, it says CMOS settings wrong.

But that message doesn't always appear after the freeze and when I enter the BIOS instead of loading the default values, the date is still right.

At the same time that happened, a partition of one of my HDs (where my OS is on the other partition) was getting Disk Check everytime I restarted and it wasn't in the registry. I moved all the files to my other HD then formatted and it was gone, no clue if it has anything to do with my current freezes.

There was once, after a restart, Windows suddenly detected a new hardware and installed a driver for it, I don't remember what it was but certainly did not change any hardware, anyone can help pinpoint my problem? I don't think it's the battery...

The correct date appears to indicate that the CMOS battery is OK, but if it is over 5 years old you may want to replace it anyway or at least test it with a digital volt meter.
Check the individual voltages in your BIOS, if any are off more than about 10 percent (12V, 5.5V. 3.0V, etc) then your power supply may be the issue.
Freezing can be caused by bad memory so you can test this with Memtest86, but this does not usually cause BIOS settings to be effected (still worth a check though).

You have to be a little bit crazy to keep you from going insane.

Memtest86 gave me no error
The power were within 10%.
There was one without a number though, Core Voltage I think?
CPU-Z gives me 1.216V.


Oh, I don't know if I should have posted this.
When it freezes, I didn't get the BSoD, the pc stopped responding. I tried pressing Num Lock and stuff to see if the lights would disappeared but no response at all, I waited like a minute then pressed reset.

Run Malwarebytes.
Remove all from start tab of msconfig except Microsoft and antivirus program, OK and restart the machine.
See that you have sufficient virtual memory.
Update antivirus program, update Windows.
Check Device Manager for driver errors or warnings, update drivers.

Malwaresbytes returned no errors
Removed all cep a few from start tab

Should have enough virtual memory (don't know how to check) Have 2 Gbs and I don't run much at the same time.

Antivirus updated, Windows updated
No drivers errors.

Can't update drivers though, no floppy to update Bios and the newer drivers require that BIOS. It was released much later for newer cpus and eSATA.


I'm starting to wonder if it's a hardware problem, all the freezes happened recently after I got bored and played a SNES rom on an emulator.. trying to not play to see if it still freezes. The emulator freezing is one thing but freezing the whole pc was odd so I didn't find it suspicious at first...

Oh, also, is there a way to check if it's the power supply?
When I go to sleep mode, the blue lights on the power switch usually flash and all but lately, when I go to sleep mode, the lights are gone. It's still on when I open the pc normally but when it goes to sleep mode, the lights aren't there anymore.
