Friend's been having an issue and I looked at his PC and I had a feeling it was the Hard Drive for the one issue, but the other issue seems to be the power supply, just not sure.
This is what's happening, initially when I went over, we decided to unplug the TV so he could take a picture to claim it on the insurance because of a power surge he'd had, but when he plugged it back in and powered the PC on, it booted fine, I questioned him "are you just messin with me bro?" He was laughing too hard to answer I fiddled around looking into stuff it was running fine, reset the computer, powers on, gets to desktop, boom crash with "BAD_POOL_HEADER" No problem, assumed to be bad RAM or maybe a bad sector on the hard drive, I would have continued to inspect, but I tried to power it back on, nothing was coming on. The TV wasn't getting a signal it was remaining a solid black, and the computer would go on, fans spinning, but no output, sent through the onboard I believe, I question you, could a power surge have caused this? and what actually went down the drain, the PSU, the RAM, the entire computer perhaps?
From what I know of his computer I know very little of his specifications:
CPU Phenom II x4
RAM 8 GB
2 HDD's Seagates 1x640 GB 1x240(?)
1 9800 GTX GPU
Any ideas are useful cause I'm stumped, he may just end up with a new computer anyway due to insurance if they reimburse him, but knowing if any of the parts are usable or anything is good to know.
