I have a problem for almost over a year now. My PC is freezing (i can still move my mouse cursor and minimize-maximize windows, but the applications are frozen, windows saying they are not responding. After about a minute all turns back to normal, all applications work). Right before the freezing, I can hear a sound from my computer, just like some component would turn ON (the sound is pretty high, just like when the blitz is recharging on an old photo-camera). I believe it to be the Hard Disk, but I am not sure, this happens mostly when i download something from the internet, or transferring files to my pc from removable drives.
My pc specks are the following:
Windows 7 Ultimate Edition
CPU> Intel Core2Duo E6420
Motherboard> ECS P965T-A
3 Gb DDR2 (2 sticks Kingston, 1 Stick Samsung, 1GB each)
Video> ATI Radeon HD 4670 512 MB
Disk Drive> Western Digital WD3200AAJS (320GB)
