Hi, Here's the system: Asus A7N8X-E Deluxe AMD Athlon XP Mobile 2500+ 2x512MB DDR400 (PC3200) Kingston Western Digital 160GB 7200RPM GeForce FX 5900XT 128MB 450Watt PSU Windows XP Pro The Problem; Crashing many times.. sometimes when loading game.. other times just wen surfing internet.. When crashing the system just suddenly reboots.. no warning or shutdown message at all.. So i've been troubleshooting; first i changed Videocard.. no good. Then i changed PSU, i tried a 450W, 300W and a 500W.. But still no good. I tried changing RAM timings and voltages.. system still sucks. Finally i tried to higher the CPU Vcore.. At default (14x133) it was 1.45v, i raised it 0.25v, no good, tried another 0.25 untill it hit 1.80 and system was still crashing:S:S:S:S Anyone know how to get me out of this braincracker? Any responce would sure be appreciated:)

it is possible to have XP set so that it just reboots whenever there is a problem instead of the blue screen of death-perhaps yours is set that way. I use win98SE but i have noticed that if i have Nview enabled (one of the nvidia enhancements) the computer keeps crashing on anything i do, took me ages to work out it was that. If nview is kept disabled it is as good as gold

Have you checked your temps?ive seen pc`s crashing and freezing when temps go beyond 61C,and also you might want to test your ram with this tool. http://www.memtest86.com/

well its definitly not my temps.. i have a Titan CPU cooler with Artic silver paste.. temps are: CPU: 39c~42c MB: 29c
