game_over Posted March 3, 2015 Share Posted March 3, 2015 A PC i manage randomly stopped booting, when powering up, the display remains black as if it hasn't picked up the signal, it does acknowledge that it is plugged in though.. there is no power to USB peripherals (mouse/keyboard).. the CPU and SYS fans spin and you can also hear the HDD and optical spin up. I have disconnected everything (RAM, optical, hdd, peripherals, etc..) with only the CPU and PSU connected to the motherboard... still nothing. I have also disconnected the CMOS and the power button trick by removing power and pushing power button a few times to release remaining current. I'm not looking to spend forever on this if it's broken I can replace it, I just wondered if there is a nothing else i can quick try? Is the motherboard dying or could it be something else?

Mindovermaster Moderator Posted March 3, 2015 Moderator Share Posted March 3, 2015 PSU, get a new one. There obviously was not enough power to turn your GFX on. Link to comment Share on other sites More sharing options...
Obi-Wan Kenobi Posted March 3, 2015 Share Posted March 3, 2015 Get a new psu. Try that before you replace the mobo. It's cheaper. Link to comment Share on other sites More sharing options...
MikeM97 Posted March 3, 2015 Share Posted March 3, 2015 I think your PSU doesn't provide the power that you need . Try to get another one [ with more Watts ] from a mate , just to assure yourself the motherboard has nothing to do with that problem . Link to comment Share on other sites More sharing options...
Regert Posted March 3, 2015 Share Posted March 3, 2015 Can you tell us anything about the computer? Age, parts etc? Also, have you looked inside? (Unpower the computer before doing that.) Link to comment Share on other sites More sharing options...
game_over Posted March 5, 2015 Author Share Posted March 5, 2015 Sorry for delay just got round to having another look... I replaced the PSU and now it's just one long continuous beep. Link to comment Share on other sites More sharing options...
+Cryton Subscriber² Posted March 5, 2015 Subscriber² Share Posted March 5, 2015 I'd give the mobo a quick examination. Look for capacitors that have popped (the top will be domed up, and maybe the sides too). Also check the resistors to see if any of them are black and look like they've blown.

XorpiZ Posted March 5, 2015 Share Posted March 5, 2015 I had something similar a few weeks ago. Turned out to be the monitor that wasn't working. Might be worth a shot, if you have a spare one about. Link to comment Share on other sites More sharing options...
MikeM97 Posted March 5, 2015 Share Posted March 5, 2015 Sorry for delay just got round to having another look... I replaced the PSU and now it's just one long continuous beep. Check for anything that may not be well connected . Link to comment Share on other sites More sharing options...
