Hi y'all I have recently built a PC with the following specs: AMD Athlon XP 2000 + THOROUGHBRED With factory unlocked Multiplier 1Gb Dual channal RAM (400Mhz) ASUS A7N8X-X Mobo Radeon 9600xt 256mb Once built and the OS installed i noticed that my CPU temp was really high (60-70 degrees) Then I went out and bought a new heatsink and fan. the temp was now 50 -60. For a few hours all seemed well, but then when i went to start a slighty demanding program it froze. I restarted the PC and everytime i get to the desktop it restarts. I have tried a new PSU and checked the RAM, all is ok. any suggestions?
