New PC does not work

post #1 of 5
Thread Starter 
I recently built a PC only for it to all of a sudden have some sort of power surge and not boot up again. I replaced the PSU which gives power to the system (all the lights go on and the fans spin) but nothing boots (also when connecting the CPU fan to the CPU_Fan slot connector it doesnt work, but it will when connecting to the PWR_FAN.) The PSU shows the wattage at the back and it says there is only 20 to 25W going to the system. I'm guessing its either CPU or MOBO failure (based upon CPU_FAN not working) possibly caused by that power surge. I have a Core2 Duo E8400 and the mobo is a Gigabyte X38-DS4. Any ideas before I go try buying a new mobo???

It sounds like a Mobo problem to me. Unless you have a spare CPU laying around the only thing I can say it disconnect everything and see if it will boot up. Maybe something is shorting it out.

What PSU provides wattage information? What PSU were you using before?

It does sound like you have a dead motherboard. However, the extent of the damage could be further.

Also you should fill out your system specs under the user control panel section. Lotsa people get irritated by not doing that here.

Like Le0 said, please fill out your system specs by clicking here.

I lost my AMD system to a PSU failure that gave the same symptoms as you. I fixed it 3 months ago by replacing the motherboard, only to have the problem happen again 2 weeks ago, this time with dead RAM as well (and possibly a dead CPU, still haven't tested it yet). Try out your RAM in someone else's computer to make sure it's ok (try just one stick at a time). Once you've ok-ed that, I think it's safe to assume your motherboard is dead. It's possible your motherboard died on it's own, but it's also possible your PSU is failing and fried it. What were your symptoms leading up to the motherboard not posting? Did your system ever randomly restart? Were there BSOD's? The more information you can give us the easier it is to figure out what the most likely cause is.
