Could a black screen and a long beeping noise at power up mean problems with the power supply?
Reader: After reassembling my PC, I got a black screen and the PC would make long beeping sounds off and on (Beeeeeep-beeeeeep-beeeeeep-beeeeeep) at startup. I switched it back off and checked all the cables and they were all ok, so I turned it back on and it worked properly. It did this a few times. Could this have something to do with a bad power supply? Computer Doctor: Most standard PC power supplies are terrible. Startup errors like this are symptoms of substandard supplies. I recommend Astec or PC Power and Cooling. You might consider a high quality replacement from one of those companies.
