iMac 20" (Late 2008) Freezing Issues
iMac 20" (Late 2008)
2.66GHz Intel Core 2 Duo
4GB DDR2 SDRAM
ATI Radeon HD 2600 Pro 256MB
OS X 10.8.2
I am having a few issues with the iMac, it seems every couple of days the iMac will just radomly freeze up. Being a computer engineer and knowing the iMac was out of date i thought it was because it was getting to hot so I stripped it down and cleaned out the inside and the fans. This did not cure the problem as it just froze a few minutes ago.
When the iMac locks up sometimes the screen is still showing what I was doing but I cannot move or do anything, one time I have had a white screen and most of the time its is a dark blue. When I reset the Mac it works perfectly fine and boots up nice and quick, also it is not hot at all.
When this happens there is normally only 2-3 programs open (Chrome, iTunes and maybe Skype), also when it freezes sometimes the music is still playing in the background and then that will stop about 30 seconds after.
Is there anything else I can do to solve this problem or a check I can do to see what is causing it?
iMac, OS X Mountain Lion (10.8.2)
