Not very happy

[MiStA PePPa]

My computer has just taken a crap. I'm not sure what the problem could be. My friend plugged in his I-pod in the front USB, and poof, the computer went off. After that, every time I tried to turn it on, I can see the lights blink on for a split second and go off. So I waited a day and tried again. This time it turns on, I can see it light up and the CPU fan is running, but there is nothing else happening. No blinking red HDD light, nothing displayed on my monitor. I got this rig at the beginning of the semester. Right now, I'm on campus, and I'll only be here for a bit tomorrow.

could be a number of things wrong. i would say power supply or logicboard. start with that. it could be cpu, video, or memory, but if you plugged a usb device in it, its got to be one of those in my opinion.

[FritzDaKat]

On the off chance there might be damage to the front usb port, I'd mabey pull the header connectors off the mobo. Just a thought.

[MiStA PePPa]

Heres what I can tell you. I tried pulling the usb connectors, I tried disconnecting the hdd, I tried different ram. The only thing I can think of is that it could be mobo or psu. I dont have a spare psu, and I don't want to replace the mobo unless I'm sure it will fix it. I also tried to reset the CMOS in a few different ways. That did nothing.

[Aramis]

If you're not getting a POST beep, it's either the PSU or the mobo. I'd try and see if you can borrow someone's PSU for a bit. However, with the fact that the CPU fan spins... it's probably the mobo.

[MiStA PePPa]

Yeah, I'm convinced that it's the Mobo. I just have to find the time to replace it.
