help on replacing ati 2600 to 8800gs?
hi, i have iMac 7.1 24 inch mid 2007 Core 2 Duo 2.8Ghz (4MB L2) +4GB + ATI 2600 Pro 256MB
and i just purchase video card "GeForce 8800 GS 512mb" which was installed on iMac "Core 2 Duo" 3.06 24-Inch (Early 2008)..
I'm trying to replace/upgrade my ati 2600 because of it overheat....80~100 celcius on idel..and keep shutting my imac off after 1~2 hour of using imac..
so i disassembled my 2007 24inch imac and installed 8800 gs video card, i get LED 1 LED 2 LED3 light on after power on. then i heard chime sound with blank screen, and chime sound is keep playing every 2~3 sec....
not sure what did i wrong...do i have to do something else to replace video card?? i'm sure 8800gs video card is working one....
Is this a good question?
