Hello,

So my pc was working perfectly, i've bought a new fans for the case, i installed them and everything went smoothly! but when i turned the pc on all fans ran so freaking fast and the screen can't get a signal!

I've tried so many things!

1- CPU resetting
2- BIOS Battery changing
3- Disconnect everything and reconnect again
4- unplug everything connected to the pc and press the power button for 2 minutes
5- i've changed the Power cable and the HDMI cable

So plz guys any tips? what do i have to do ? did i just killed my motherboard ?

Was your machine having issues such as freezing, crash or sometimes straight-up not POSTing before you added the fans, that is a sign of a dying motherboard or bad RAM. Try with one stick in the motherboard and see if it POSTs, if it does then try every stick of RAM to pinpoint the bad RAM stick. if it does not that could mean maybe a bad CPU. Do you have another CPU you could try to put in the motherboard?

Sound like a PSU issue. if you have a hard drive or DVD drive, connect it to the PSU, then short the green wire to any black wire, if the HDD and DVD drive turns on, it is something else. Likely PSU is dead, because if it was the MB, there would be lights on and fan running.

At least those
