Hello, I built a system about a year ago now. It's components were an ecs black something or rather A780GM-A rev1.1 AM2+ motherboard, phenom II X4 810 CPU, 2*2 GB ddr2-1066 ram, 808GB hdd, gts250, Great wall of china 600W PSU. OS was xp sp3, system ran fine, stable etc.
I upgraded the graphics card to a gtx470 recently. Didn't upgrade my Great wall of china PSU. System became unstable etc. I suspected something was going wrong. Swapped back out the graphics card and the system still froze. Reinstalled OS, same thing.
Then I fried the northbridge on my ecs motherboard by pluggin in a crt to the motherboard when the system was running (I do things like this and usually get away with it). So new motherboard it was (GA-MA74GMT-S2). I somehow managed to get a motherboard with a slightly older chipset (I think), however I was hoping the quality was abit higher being a gigabyte and all. This motherboard was also an AM3 mobo and so I had to purchase some ddr3 ram. No special brand but not a great wall of china brand either. I also purchased a coolmaster 700W PSU.
To my great annoyance the freezing has continue. The same problem happens under XP, Win 7, and a live linux cd. I am looking at my CPU. The problem has become much worse now btw, it freezes quickly. Can I adjust core voltages and timings to get this beast going? I really want to play some more Armed assault 2. Thanks for your time!
