I've been using my setup for over a year without a problem. Now, when I boot the system will restart itself over and over again at random times during the boot sequence. Sometimes it will restart right away, sometimes it's after I'm in Win2k. I'm 100% sure it's not the HD or power supply. I totally rebuilt the computer, tried two new harddrives and power supplies. When it hasn't been restarted in a while it usually restarts over and over within 5-10 seconds of first powering on. Could this be the motherboard, or is my processor frying? I've tried reseating the processor already. ECS D6VAA motherboard Don't know whether to drop money on a new CPU or motherboard. thanks for any help

Probably an electrical problem on the motherboard. Why? The erratic behavior happens in in two very different places - startup (BIOS control) and in Windows (OS control). One or the other is a different problem. Top Possible causes: CPU is becoming too hot. (possible even with fans, heatsink etc.) Motherboard capacitators are fried. Or just general temp. problems with the board (check the bios for temp. data after a reboot/crash). RAM has bad blocks (use memtest86), is somehow incompatible, or just bad. >Likely Causes: A power supply that is not approved by the motherboard maker A faulty video card (is it cheap?) A conflict between Windows Power Management and BIOS controlled Power Management (see Power Management under Control Panel) IRQ conflicts Driver errors

I believe this is a common problem with ecs motherboards change your board and the problem will be fixed!

I'm replacing the motherboard, with another ECS (unfortunatley?). Crosses fingers. Thanks for the replies. Jason
