Ok, so I started up the PC that we use for watching netflix and the like on our Sony Bravia, and I got this error on the POST screen:

CMOS Checksum error - Defaults loaded.

Does this mean that the CMOS has been cleared?

Update:

Now the CPU Usage is at a constant %100, and the boot up process is really slow now.

Typically CMOS Checksum Error results from a dead, or mis-seated CMOS battery. Or from a motherboard jumper, but if you haven't messed with any jumpers, I'm guessing its a CMOS battery.

Was the time off when you booted up the computer?

Yes, the time was changed. Also, it was working fine yesterday, but then today I noticed the power switch was off, so I turned it back on and that's when it started acting this way.

Dead battery. If the power switch was off, and the battery is dead, there is no way to keep the CMOS settings, including date etc.

Thus when the power was restored, the CMOS settings were lost and restored to defaults.

If CPU usage is at 100% find the PID of the process doing it, and terminate said process. Google any issues with that process and CPU usage.

Try another battery. It could also be the board is going bad. I've heard of that problem you're having after massive overclocking and bios corruption. Might be a time to call up the foxconn RMA service.

I tried ending a lot of the processes, but the Avast processes wouldn't let me end them because I "Didn't have permission," which I think may have something to do with it, cause those particular processes use the most memory.

It's not the rig I built this is an older PC that we use for watching Netflix on the TV (so, it may very well be the board or battery is going bad). I don't remember what brand of board it is, but I'm pretty sure it's too old to RMA.

Umm no... Not if you have v5. v5 is limited to an idle memory ceiling of 50MB, Explorer alone is usually more than this.

Which OS? XP? Vista? 7?

The processes maybe password protected from within aVast! or you may have the "aVast! self-defense module" running. In which case you'll need to disable it and then try to terminate the processes.

I meant according to Windows Task Manager, also I'm using XP.

WTM is wrong lol, aVast! processes are limited to 50MB unless running scans.

Did disabling the self protection module allow you to kill it though?

As that is apparently what is causing high CPU usage?

So the memory being overused is throwing the CMOS Checksum Error?
