My config is MSI p45 Neo motherboard,Inter core 2 duo E6300,point of view 8800gt with 512 mb , and 2 gb of ddr2 800 mhz ram and 500w power supply.Im runnin it on xp 32 bit sp2.The problem is some times when i play games like gears of war or crysis(all at highest settings @1024 X 768 the comp hangs.If I restart the comp it works fine.Again sometimes it doesnt happen at all even after continuous 10 hrs of intense playing.So wat can be the possible problem? similar problem occured when i was working on 3ds max
