Well I "had" Win8 developer preview and I would get "CLOCK_WATCHDOG_TIMEOUT" blue screen error whenever I tried to play Portal 2. Now I have Win7 Pro x64 and I still get the error when I try to play Portal 2. So do I need to RMA FX-6100 or my Gigabyte 990FXA-UD3 motherboard OR is there a hot fix for portal 2 that will fix this error? If I have to RMA how long do you think it would take from Tiger Direct?
