I bought a ECS K7VTA3 Motherboard from FRY's. Since so many of these boards are bad, and had to already return one once, I had it tested at the store to make sure it was ok. Unfortunetly, the processor was bad and to make sure that was the problem, I borrowed the processor from another computer that had a ECS K7S5A motherboard. that did the trick and confirmed that it was the processor that was the problem. After putting the processor back in the other computer it powered up, started the boot up but shut down before finishing. It seemed that the processor had been running extremely hot and had not tolerated the changes. So it was time to buy another motherboard - cpu combo. (also ECS K7VTA3) New Memory, (the old board had been able to run SDRAMM or DDR.)and new power supply. All this and the computer would do the exact same thing of booting up and then before finishing, cut off. Does anyone have any suggestions besides a gun? Thanks in advance. Lee

Sounds like a heat problem. Did you use thermal paste between the CPU center core and the heatsink? Did you use new paste? Check the bios CPU temps. Make sure the heatsink is installed properly. Set bios for fail-safe defaults.
Last resort only. Make sure everything elso is checked first. My board has faulty motherboard temperature sensors and the temperature fluctuate wildly. It may shut down if you have Shutdown Temperature enabled in the bios under PC health and a faulty sensor..
I have a problem with this board shutting down that is being caused by the HSF not sitting on the CPU right when the PC is upright. On it's side it is fine. My thread is in general hardware "2 PCs 2 Problems".
