My PC refused to turn on today and I thought I had knocked out the power cable so I just took it out from the PSU and pit it back in. I forgot to flip the switch off but when I plugged it back in it started making a long continuous beep that I let go on for about 4 minutes till I decided to flip the switch off. I guessing the problem is internal, some piece of hardware preventing it from launching and that's the point of the beep. If you guys know it would save me the trouble of digging around test each piece to figure out the problem. On a side note I heard that some beeps the computer makes are error codes but this is a long continuous beep so idk
