I've recently bought my cpu which have asus P5QC m.board,Intel Core 2 Quad 2.33ghz processor,Transcend 2gb DDR3 1033bus ram, Asus 9600gt 512ddr3 g.card and value top 400Watt psu..........but it seems something wrong in my system ,cause its reboot anytime without showing any error or message. say ,i just turned power on and its gonna reboot. sometimes its continuously reboot 3- 4 times in less then 10s and then shut down.i have to switch the power off for sometime & after 15m its become normal. the vendor already changed the m.board . i replaced my current ram by a Adata 2gb ddr2 800bus ram but yet i get no solution .what more i should do to solve this pain ??????
