So, here's what I built:
AMD Phenom II x4 965 3.4 GHz 6MB Cache
MSI 790FX-GD70 Motherboard
HIS Radeon 4870 GPU
850W Rosewill PSU
4x 2GB GSkill DDR3 Ram
320GB 7200 RPM Seagate HDD
First build went surprisingly well. (New to this, so it's REALLY a first build.) Booted up first try, no problems installing Win7, etc. Worked fine for the last 3 days.
Went to turn it on last night (after shutting it down the night before with a few Win7 updates) and nothing. Turned the PSU on & off, tried again, nothing. Took the cover off, checked all of the connections, turned it on again, and the PSU fan started to spin w/ LED for about half a second, then a "spark" kind of sound and then nothing. Upon repeat, it wouldn't do anything again, but every once and a while it would start to come on and then pop.
Power button on the MB itself lights when the PSU is on, but nothing else happens when the button is hit. Husband thinks we might have fried the CPU (woke it from sleep state and the Core Temp was ~48C) but I'm thinking we've got a short somewhere, or some other PSU issue.
Anyone seen anything like this before? I'm totally stumped.
Thanks.
