I've been facing a pretty weird problem lately. Everytime I start my PC it powers on (fans start spinning etc.), but it does not load any of the attached devices (i.e. monitor, headset, keyboard etc.), at least not for the first 15-30 minutes of continuosly restarting it.

(Just in case that was unclear: Monitor stays in Standby, lights on the mouse/keyboard don't go on etc.)

After a while it'll suddenly work perfectly, but it does not give me any indication of errors having occurred or anything like that, nothing. It also crashes when I leave it in Standby-mode for longer than 5 minutes.

Short version My PC is weird, here's why:

  • Upon being activated, it boots, and then starts restarting 2-3 times
  • It does not load any of the attached devices until I've restarted it long enough (15-30 minutes)
  • It crashes when left in standby-mode for >5mins (no sound, only blinking lights, fans off)

My PC is sort of a welfare PC, it was around about 400€ total, it's 2 years old & using Win7. I'll add specs if needed.

Does anyone have any clue what the potential cause for this is? I've never heard anything about this, I cannot find any documentation of this problem, and it's starting to get annoying, spending 15-30 minutes each day just starting the PC.

  • If possible try a Linux usb stick and see if that boots. – TheKB Jun 2 '16 at 14:14
  • @TheKB Sadly not possible :/ – Seth Jun 2 '16 at 14:16
  • 1) are you cutting all power between restarts? Some motherboards "double post" when all power has been cut. this is not unusual but is a BIOS bug; If you are not waiting long enough and pulling power at the wall, you might be "resetting" the multiple boot thing unintentional;y; 2) some intel cpus have a "deep sleep" that draws so little power that the PSU restarts (google: "haswell psu compatibility"); some BIOS have a "power loading" ("dummy load") setting to mitigate this.. – Yorik Jun 2 '16 at 14:19
  • @Yorik 1.) No, I do not. I just restart it normally via the power-button. 2.) It's an AMD Athlon x4. :/ I really am unsure what's going on, it's been like this for quite a while now. – Seth Jun 2 '16 at 14:22
