PC refuses to boot

[ElTopo]

I usually wouldn't come here for such a thing, because my PC does this every once in a while, but today it was just stupid dumb. I just wanted to turn on my PC, but it took at least 10 attempts to get it working. It either rebooted on the Windows loading screen and then the Windows Automatic Repair system wanted it to Restart properly, or it just didn't POST at all. It even turned off in attempt number 5 or so. What is going on here?

I thought it was a PSU problem back a few months ago and I replaced it for an older one that was in my previous computer, but now it is the same all over again.

 

PC Specs:

 

 

• CPU: Core i7 3770
• MB: Asus P8z77-m pro
• RAM: Kingston HyperX 8Gb (1600mhz)
• GPU: Zotac Geforce GTX 650 (AMP! Edition)
• Storage: Samsung 840 Evo + Seagate Barracuda
• PSU: A quite old 650w PSU (Gear)
• OS: Windows 8.1 x64

 

I don't know what the problem may be... Help

Try with just the IGPU it could be your GPU's old age.

first of all i'd try to unplug everything and plug it in again

1 ram... 2 ram sticks etc

then gpu etc

 

maybe update the mainboard

 

if you made it onto your "desktop" then i'd update all drivers etc

Try turning autorestart off (rclick My computer, properties, advanced system settings, startup and recovery settings, tick automatic restart off.) so you can check the bluescreen code.

I reseated the RAM and some cables, and moved the 24-pin cables that were crushed behind the storage drives (my case is so tiny that cable management isn't an option). I rebooted the computer around 6 times and all attempts worked flawlessly, but I'll see how it really behaves on the course of the next days. Thanks everyone!

After half an hour of experimentation, I found the origin of my problem. During the Asus and Windows loading screen, the system is looking for external devices such as keyboard, mouse, earphones, etc. (And updates them all?). I also had plugged in a Mayflash Gamecube Controller to USB adapter, and this seems to be glitching out on the device detection phase, making it reboot indefinitely.

I never thought a seemingly harmless thing could produce such an annoying effect on my computer  :wacko:
