I'm not sure if this is the correct place to start this topic; mods, please move if necessary.
I'm having some problems with my homebuilt PC. It has been working fine for almost 12months, but then suddenly something went wrong.
I was playing Oblivion, when suddenly the screen flickered and it froze. no biggie, ill just restart. however, when i restarted my monitors light would keep flashing on and off like my PC was on standby when it clearly wasnt.
I've tried everything but nothing is working. used a different pci-e slot, a different graphics card, a different port on the graphics hard (DVI).
The PC turns on for a few seconds, the monitor shows nothing, then it shuts off, and then turns back on again and stays on; still nothing shows on the monitor.
well my system is already set up, and it was working fine for several months up until last night.
i wish i had spare parts, it would have been so much easier to swap things around and see what the problem is.
I have a really old computer that no one really uses, but it still works. I cant use it's power supply on my computer (the old computer has a 120watt mine has a 750watt), but mine will fit on the old one.
so my question is; is it safe to hook up a 750 watt power supply to a computer that normally runs on 120watt? It has all the right connectors.
