ok so i have a computer that i built my self its a AMD athalon xp 2900+ on a Abit KV7 motherboard with a ATI radion 9000 pro video card with 2 sticks of 512MB ddr PC3200 memory running Windows XP.
as of late when playing games or just doing anything that uses a little bit of my prosesing speed it will die the first time it will take about an hour then after that it only takes about 3-5 min for it to die again
when it dies it gives no warning or errors just dies now when i hit the button to turn it back on it wont turn back on but when i turn the powersuply off for a few seconds and turn it back on it will start back up like nothing happened.
when it first started i thought maby it was overheating so i took of the side panel and put a desk fan pointing directly at the cpu and downloaded the Program Speed Fan it still did it some times it would die at about 48*C and sometimes ive even seen it as high as 58*C
so i thought maby my memory was bad so i through some of my old PC2100 in that i know works and it still does it anyone know what i could try next im lost
