My CPU Fan won't spin, GPU fan spins at max, and PC won't turn on

Rising fury · Apr 15, 2014

I opened my pc this morning and my GPU fan was doing an insane sound.. like ive never heared before and my cpu fan isnt starting...

kapitalistas · Apr 15, 2014

y help try turn the cpu fan by hand is it stock maybe dust build up.

Rising fury · Apr 15, 2014

Dust didnt build up. My PC is 3 months old. All clean.

Jacob McIntosh · Apr 15, 2014

Make sure that the CPU fan header is plugged ALL the way in.

chris987 · Apr 15, 2014

try clearing cmos(hardware reset) and check psu condition! and full specs please!

Donand Ironman · Apr 15, 2014

Did you overclock anything?
If no try cleaning both fans the gpu and the cpu. Dust would build up if you don't clean it every 2 months.

Rising fury · Apr 15, 2014

There is no dust no where ive cleaned it up and i didnt overclock my CPU

PC specs :CPU Intel core i5 4670 LGA1150 GPU : Nvidia GeForce GTX 660, MOTHERBOARD : Asus Z87-A, Power supply: Antec HCG-750 (750VW) RAM: Corsair Vengance 2x4gb CASE: Raidmax ORION

Rising fury :

your specs are ok and that psu is a good one and more than enough for your system. even so, make sure power supply fan is spinning and not overheating. also make sure you have replugged the cpu fan header as suggested earlier!
you can even try re installing the gpu. if all fail, remove everything except cpu and one stick of ram and see if you will have a post. if you do, re install all parts one by one to find the possible fault one.

Ive unplugged and replugged everything and its still there. When i turn on my pc the CPU redlight is on and my GPU fan are running like no tomorrow

kapitalistas · Apr 15, 2014

di you have possibility to measure power with multimeter on thous cpu cables or try different psu.

chris987 · Apr 15, 2014

if psu is modular try different cables and make sure your power plug is grounded and mobo properly installed and sitted on the standoffs preventing from shorting out!

Rising fury · Apr 15, 2014

it is grounded and the mobo is sitting on they 5 standoffs..

chris987 · Apr 15, 2014

check also the meaning of the red light on mobo manual. such sudden fail most probably a psu issue!

Rising fury · Apr 15, 2014

Its the DRAM LED

chris987 · Apr 15, 2014

Rising fury :

so dram failure as it appears, check sticks one by one

Rising fury · Apr 15, 2014

Which sticks?

chris987 · Apr 15, 2014

Rising fury :

Corsair Vengance 2x4gb check them for any burnt pins or if they need further push to securely fit. also as i sead earlier try to post with one ram stick at a time.

Rising fury · Apr 15, 2014

like try to start my pc with one ram stick?

chris987 · Apr 15, 2014

Rising fury :

you need to remove them and examine them closely. if both appear fine then try posting with one ram stick at a time

Rising fury · Apr 15, 2014

Okay ! i've unplugged the ram and replugged at and now the DRAM LED is now off. I restarted my PC and then it started correctly and then the VGA LED light up red and then my PC turned off, and then restarted. And then it went on, the BOOT LED became red and my screen is still saying ''No Signal''

First, the bad news----------------------It sounds as if your Power Supply is (or has) partially failed. That may well have cascaded into other components, but the first step is to replace the Power Supply, then check for other potential failure points (MB, Memory, CPU, HD) and pray for good luck!!

Rising fury · Apr 15, 2014

Why is this happening..... it was running perfectly yesterday..

kapitalistas · Apr 15, 2014

can your make a picture how cables connected on the motherboard.

chris987 · Apr 15, 2014

Rising fury :

electronics...what can i say. dont give up! the important think is to manage a post , to make sure that mobo - cpu -ram is ok.
