My dad wanted me to do something to his computer, so he took the tower here -- I unplugged my computer, plugged his into my keyboard and monitor and stuff, fixed what he wanted and he went. So far so good. Then, I plugged my computer back in and it did nothing. The fan was running and the light was on at the back, but the monitor said: "No Signal". I basically turned it on and off and played with the cords and fiddled and opened it up and pushed all the cards in hard, etc for hours. Had another go at turning it on and off , and even letting it run for an hour in case it was just confused about something, but nothing worked, so I put it on the floor, forgot all about it, figuring that it had blown up or something -- and plugged in my old computer. I used that (old computer) for 10 weeks; up until today... Dad brought his OLD computer here (completely different computer, yet unmentioned), so that I can reformat it and let my brother use that one at his house. I plugged it in and it did the same thing as my other computer did. Except it made one continuous beep, pause one continuous beep (which goes on and off indefinitely). So, I looked at the computer and thought: Ok, that one has blown up too. No now I have two computers that were plugged into the same power point, same cords and neither of them work. But "My" old computer that I started using after my new one blew up is working with all the same cords and at the same power point, and that hasn't blown up. Anyway, so being pretty unhappy about having two computers not working (doing the same thing, no signal), I decided to go and set them up in a completely different room, with different cords and everything. I was hoping to eliminate the power point and the cords. I turned them on and off a dozen times, switched the wall off and on, etc. Pushed the plugs in nice and tight, tried everything and neither computer worked. Then, I switched my new computer (the one that I had put on the floor for 10 weeks, mentioned above) off at the wall while it was on -- then switched the power point back on again and tried to start it. It WORKED! I'm not complaining, but what's the deal man? How can it not work -- then, after after all that, all the sudden just work? So, the only thing I can think of is maybe the PSU got "partially" fried? is that even possible? Maybe all the turning on and off resurrected a faulty capacitor or something? Has anyone ever experienced a PSU that works on and off? Maybe it is half fried?
That sounds really strange. Never experienced anything like that. Had only fried RAM chips, GPUs sometimes the BIOS battery was dead. If I were you, I would bring it to an expert, just out of curiosity. Tell him your story, he might knows what exactly went wrong.
I Think your power outlet line voltage is not stable for your computer , I suggest to measure this with voltmeter .use stabiliser unit to stabilize your computer power.
