Nope i never done oc. the problem happen after i finish installing the onboard vga driver. when entering windows, my screen flicker-flicker a bit. then

after sometime it turn black. if i plugin my hd4850 gc, i kept freezing after booting up into windows. already replace the GC and RAM but seems its not

the problem.

if can , aviod to install the driver from cd ... download the latest driver from official sites , and try to install it and see

the chipset is very hot.try to check the contact of processor to the heatsink.
have you try using the build in gc first. i beleive its a heat related issue.
