Motherboard
Product Name ECS PT800CE-A
Model Version 1.0

CPU Intel Pentium 4 rk80546pg0881m

Memory Micron MT16VDDT6464AG-265B1 512MB PC2100 266MHZ

HDD western digital wd800bb

Power supply: 250w Newton Power from a gateway select athlon 1100

Operation System Windows XP Home Edition

I installed this ECS PT800CE-A motherboard and the drivers from the cd that came with it and the system worked fine for a few hours. I left my computer on and about 1 hour later it shut down and would not start when I click the power button. With the ATX1 and ATX2 power cables attached, it would not start, however, if I remove ATX2 the fans will run but nothing shows up on the screen. I disconnected everything from the motherboard and took it out of the case and it still didn't power up. I tried removing the CPU, leaving only the motherboard as it came in the box and it still didn't power up. I even cleared CMOS and the problem still persists. I was told by an ECS technician that I should use a power supply rated at least 350 watts. Could this motherboard be defective? Did I damage it by using an insufficient power supply or will a bigger supply bring it back to life? Any information you can provide is greatly appriciated. Thank you.

Bubblersound: I'd try a new power supply. Get an Antec or one comparable. Don't buy something cheap. I don't think you messed up your motherboard by using an underpowered PSU.
Good luck.

I think you just killed the Power supply but with the other connector unconnected it has enough power for the fans. Get a new Power supply. Like he said, don't cheap out. Enermax is and excellent brand.
