I'm sending out an SOS to all the expert computer builders out there. I just finished building my first ever computer from scratch. I've fiddled around before with new memory, graphics cards, sounds cards, and power supplies, but this is my first ever new build everything from scratch assembly.
Problem is, it doesn't work! When I hit the power button, all the fans turn on, my LEDs come on, but only for half a second and then they turn right back off. I've read through several posts that say to removed the motherboard to eliminate possible shorting, but that didn't help. I've checked the seating and reseated all my components. I verified that the CPU has no bent leads, and that the heatsink is mounted properly. I reset the BIOS and removed the battery for 20 min. I removed all but the bare essentials, did an out of box powerup using screwdriver to short power up pins, and nothing changes. Same half sec power on then off.
Here's what I'm trying to build:
nForce3-A Motherboard
nVIDIA NF3 250 chipset
AMD Sempron 2800+ CPU
Kingston KVR400 512MB
RAIDMAX Scorpio case with 420W pwr supply
ATI RADEON x700 PRO AGP 256MB Graphics Card
I have no idea what to do next. Seems similar to the CPU overheating auto shut off problem that I've read about in other threads, but I don't know why my build would be doing that. I don't know if I need to do something different or return something. Is the CPU bad, is the motherboard bad, is the power supply bad, is the case wiring bad, do I have bad jumper settings? Is there a guru out there that can help me?
Thanks
