Hi all, My PC has recently started to randomly freeze when gaming, the computer is about 1,5 years old so I still have warranty on all components. It first started a few weeks ago, a freeze when I was playing a game, it started happening more often. So I wanted to figure out what the problem was. This is what I did: Reinstall Windows -> No succes. Replace GPU with an other one I still had left -> No succes. Replace Memory with some other DDR2 memory from my dads pc -> No succes. Northbridge is rather hot so I put a fan on it -> No succes. CPU is probably fine, it survives Prime95 for hours, it just crashes in games. So maybe its my motherboard? Hardware: Asus P5Q Pro (Latest BIOS) Intel Core 2 Quad Q6600 Corsair Dominator DDR2 1066Mhz 2x2GB Ati Radeon HD 4870 Cooler Master M620 620W PSU Samsung Spinpoint F1 1TB Anyways heres my minidump, if anyone could analyse it. Thanks in advance.
