Hi, all. These days my pc refuses to power on once I switch it off completely, for about 10 seconds. I don't remember exactly when it started happen but I think it's getting worse and worse. I mean I remember when I built this pc a year ago, PSU was quite responsive to power switch and it powered on almost momentarily at all times. But now it takes ages for it to power on especially after I strip things out and put things back together. You won't believe me but sometimes it takes as long as 1 minute for it to respond to power on signal! But once it powers on, everything seem to work normal, no sign of errors at all and I can play games for hours. And it always power on immediately in the morning which makes things more difficult to understand. So what do you guys make out of this strange symptom? Do you think my PSU is dying or what? BTW, while it struggles to power on, I noticed my keyboard lights(num lock, caps lock and scroll lock)and webcam light are flashing randomly. I have rebuilt this system numerous times (for cleaning) but that didn't help either. BTW my PSU is antec neopower 480 and I have already requested RMA and waiting for a reply from the antec support desk. Do you guys think new replacement PSU will fix this problem? Thanks.
