PC Won't turn on with GPU

[fikritheins]

So, i was not using my pc for about a month because i'm away. So as you guys expected the dust is clogged up the system. I tried to turn it on at first, but nothing happens. Then i cleaned the whole pc.

 

After cleaning, the pc still won't turn on.

I swap the ram slot , not change

I disconnect my gpu card, and it turn on.

 

I'm currently using the onboard graphics card and it's killing me. Is there any way to fix it? I checked the gpu, nothing burnt, i cleaned and applied thermal paste several times in the past.

 

MY pc is : Pentium G3240, Asus H81M-E (From some prebuilt), 8 GB DDR3, 1TB WD Blue, and XFX 7750.

i know it's old, but it helps me a lot.
 

thanks.

put the gpu in another pcie, to make sure its not dead.

you can plug it in the pcie 1x (the yellow shorter one) and try booting.

If you have access to another PC, or a nice PC shop, see if you can test the GPU that way as well.
