A number of issues are occuring on my system. Not sure if they are related, but that is my hunch.
My processor is overheating - I cleaned the CPU fan and inside of my case.
Also, I noticed that there is a squeaky/high pitched noise coming from my computer as well. It is dependent on activity - open an application and it squeaks; idle and it is quiet.
My PSU fan is not spinning - just noticed this when I tried to restart.
In addition my general case fan is spinning slowly - slower than it would on the slow setting, and it is set on High.
My current system consists of:
Asus P5B Deluxe motherboard
Core 2 duo E6400 processor
8 GB g.skill ddr2-800 pc26400
Windows XP Pro
450 w psu
I have read on other forums that the high pitched sound could be a motherboard problem. There is clearly a PSU problem. my case fan might be related or maybe not, but it also seems my CPU fan might not be keeping up.
