Ever since, my first PC (about a year and a half after I build it), it would randomly hang, but mostly just randomly hang/crash with a ear-pinching screech sound from the speakers. Then I would have to pull the power, and re-start. It would do it randomly, alot if I left my PC overnight to do a download / update, but would also do it on login - first time after being off for a number of hours, randomly during coding (websites and eclipse, nothing that could damage the PC), randomly while listening to music, or watching a movie. It would also not do it for a month or two, and then come back. And maybe go for a week or two, then do it 3 times in 20 min. When it hangs or crashes (NEVER a blue screen) the power lights from my keyboard (microsoft x4 sidewinder) and my mouse (microsoft x3 sidewinder) go out, I push them, and the light stays on for 2 seconds or so, and then goes off again.
I took it to different PC shops (Matrix warehouse, Incredible connection, etc) to have it looked at, they ran tests, and came up with nothing each time.\
I have tried upgrading, I first formatted my PC +- 6 times, then I started upgrading piece by piece, Hard drives, OS's (windows and Linux), RAM, MOBO & CPU, PSU, CD drives, cases, screens, you name it, I upgraded it.
But still to this day, after upgrading literally EVERYTHING it still hangs / crashes fairly regularly. I am stumped, and I cannot afford another 8.5k for a decent PC, as I need to do coding, recording for an album, and graphics design in photoshop.
I dont think that it is virus' as I have formatted to this day +- 20 times, and upgraded hard drives and used friends hdd's many times.
PLEASE if you have ANY advice on what to do, I am DESPERATE.
But I need to try start upgrading it again, is it worth upgrading piece by piece to the same PC that keeps hanging? or should I just build a new PC, as in not let the new components even TOUCH the old, as they could be cursed (haha, a joke).
Thank you in advance,
