[SOLVED] PC Won't boot + Fans power on Black screen/No signal

[khaled_82]

Hey guys,

The cpu fan and gpu fans spin but I can't get any video signal to the monitor.

Things I have tried:
Remove CMOS battery for 1 minute replace and try (no boot)
I removed my RAM sticks and tried one at a time also cleaning the seating areas of dust (no boot)
I removed my CPU and cleaned the heat sink (made positive CPU power cord was plugged in along with CPU fan, no boot)
I unplugged my power cord and held the power button for 1 minute multiple times (no boot)
I disconnected my unnecessary components, disc drives etc (no boot)
I completely took everything EXCEPT for the motherboard out of the case and re-seated it (no boot)

Specs:
CPU : AMD FX-8350
MB : GIGABYTE GA-970A-DS3P DDR3 AM3+
GPU : MSI 220GT 1GB
RAM : 8GB 1333MHz
POWER : CORSAIR CX450M

I have been using it with no problem
Anyone have any ideas?

Thanks!

How old is that Corsair 450 watt PSU?

New, used, condition? Source?

Has the PSU been heavily used for gaming, video editing, or mining?

Can you borrow another GPU to test your system with, whether it being from a friend or someone?

4-to-5 Year Old , normal used.

I borrowed another GPU from a buddy of mine, but I can't get any video signal to the monitor.. PC Won't boot

So it isnt the GPU.
Well it can only be cpu/mobo/ram.
What can you swap out?
Do you know anyone who has a AM3+ cpu?

 

[Dj0gany]

Also do you have a motherboard speaker?

Motherboard has horrible vrm for FX 8350. I think the MB is down.

PSU: 4 -5 years old....

A likely suspect in my mind.

Do you have a multi-meter and know how to use it? Or know someone who does?

If not, per @Master Djoza try swapping in a known working PSU as well.

Just a a matter of elimination before the motherboard is deemed down.

Motherboards and psus are always on, if plugged in. They are in a Standby state, just waiting on a start signal supplied by the switch. So if resetting cmos by removing the battery or shorting the pins, unplug the psu first and allow the caps to drain (push power button for 10-15 seconds) first or cmos retains enough juice to maintain the files.

What happened to the pc signal? Did a cleaning and unplugging cause the loss? Did you shutdown one day and nothing the next? Usually there's a cause to things just quitting.
