Alright..so here it goes.
To start off, I would just like to say that I have been building computers since I was 14. I am now 25. I'm no genius, however, I know more than the average person my age about computers. I've built many computers for friends, troubleshooted hardware/software issues and I've always been able to come up with a solution. I have a few friends that I went to high school and ITT Tech with, so when I get stumped I usually go to them to ask for help. This time..well, it just makes no sense at all.
My roommate and I got a new apartment and had to move all of our stuff to the new place..naturally. I made sure to place his computer so that it would have minimal contact with other items and wouldn't budge from where it was. When we got all of our stuff into the new place and he setup his computer, it didn't turn on. No fans, no lights, no noise, nothing. Unfortunately his mobo doesn't have a power indicator and I don't have a mobo tester so we weren't able to test the mobo.
I began to troubleshoot like I always do. Thinking I'd get this figured out in less than an hour or so. It's been 11 days since this happened, and I have tried something new everyday since then and we still can not figure this out.
So first I figured, mobo or power supply. I took a paperclip and did the ghetto power supply test (which from experience even if the power supply turns on, doesn't always mean that it still works properly) and the power supply fan began to spin as did the fan that was connected to one of the molex connectors. So just to doublecheck, I took the power supply out of my computer and put it into his. Nothing.
Then I was thinking; since his case is one of my dad's old ones from like 6 or more years ago, maybe somehow the case wiring is jacked, and the power button on the front is not working as it should. So I connected the leads from my case to his mobo with my power supply connected. Nothing.
At that point, the only conclusion I could come to was that his mobo fried or something happened during the move to make it inoperable. So we ordered a new mobo on newegg. Got it a few days later, took his old mobo out, put the new one in, triple-checked that everything was plugged in where it needed to be, and pressed that darn power button. Nothing.
Now, knowing that my processor, RAM, and power supply are all in working order, and also that his mobo will accept my processor, I began the extremely tedious process of dis-assembling my computer to take out my processor and insert it into his mobo (the brand new one) to see if that would resolve the issue. I basically had to take 2 computers apart completely and put one back together completely, just to press a power button to see if it would work. Guess what? 3 hours later, when I was done I pressed that power button...NOTHING!
For the hell of it, I took all of his RAM out, and put a single stick of my RAM (also accepted in his mobo) to try that. Nothing as usual.
So we basically built a whole new Frankenstein and he has no life. I'm super-duper stumped guys. I've never encountered anything like this before. It just doesn't make sense.
We are in a band, and my roommate's computer is what we use to do all of our recording with. We need this to work. He also records other bands/artists for $ so he's pretty pissed as well.
If someone could help us figure this out, we would be eternally grateful. Thank you for your time.
