I was wondering if anyone could please provide any ideas to the problem I've been having with my PC. I have tried on another forum but no one seems to be able to help.
The problem started when I had to force turn off the PC from the external power button. Its a long explanation why I had to do this, but its something I do rarely as I know the damage it can cause.
Anyway, I was getting the error message i think it was along the lines of 'CMOS Checksum Bad'. I continued and the next time I restarted, the CPU fan (which will normally spin full max for a second and then slow down) went to maximum fan speed constantly. I can tell its the CPU fan because I can feel the extra power at the vent at the side of my PC. And this even happens on a cold boot.
I did some research and I removed the motherboard battery (thinking that this might be the problem) and replaced it. An error came up saying 'CMOS error incorrect time' I think it was. Now when i ignore this, obviously the time and date are wrong on my PC, however I can use the computer without the loud fan noise. I left my PC on for a few days (I normally do this anyway) without any problems. Until I had to do a driver update, then after restarting, the same problem.
I just bought a new batttery for the motherboard, thinking this was the problem. I changed them over, got the Error message about the date and time, so I inputted the correct time and date through BIOS, and then once I saved and the PC restarted, the fan is making the same spinning noises (max speed) again.
I know its spinning at a higher speed because I have found out its running at 4000RPM and normally its about 1000RPM (I think).
I would be greatful for any info at all really.
