Case Fans stops working

[poleon178]

Hello,
I have a big problem with my Case Fans. They just stop spinning after 10mins of gaming. I tried to restart my PC but nothing changed. I went into the BIOS. The don't even regonize. Giving them a little start help, they look like they want to spin. I took my Multimeter and I just get out of all plugs (except the CPU Fan which is working perfectly fine) just 0,77v !?!?? 1 week ago I had no Problems. A few days ago I upgraded my RAM and also got a new Keyboard. I had 1 week no problems. A BIOS reset also changed nothing. Fans a correctly connected.

When posting a thread of troubleshooting nature, it's customary to include your full system's specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

Are you on the latest BIOS revision for your motherboard?
How old is your PSU? It'd help us to know what the upgraded parts are and what you upgraded from?
