I'm testing the following newbuild (its only 20 days old) setup which sometimes crashes without reason : AMD 3870k APU using 1GB of total DDR3 RAM GA-A75-D3H Corsair Vengeance 8GB DDR3 1866 MHz @ 1.65 V Corsair CX500 V2 PSU Windows 7 X64 Ultimate SP1 all the hardware has the latest driver version (mb the latest firmware) AMD Catalyst 12.8 When Mozilla Firefox 16.0.1 is in use sometimes the browser crashes and reboots. Also may a BSOD will occur, but only two times I noticed it. When the system is in hibernation mode and awakes the screen shows a multicolor palette and hangs. This failure not happens often, but it happens. Sometimes the system awakes alone when it is in hibernation mode and hangs with the multicolor palette! Running furmark and prime95 for 3 hours an so, nothing happened. System found to be stable! What should I do? It is Catalyst's fault?
