Hi, recently I bought a new psu while my old one is in a repair shop In hopes of actually using my pc again in months thing is evrything spins and nothing shows on display I tried swapping ram cleaning ram resetting bios switching cables switching monitors tried with and without the gpu etc. So I was thinking something might be wrong with it so I took my cousins pc to diagnose if my components were acting up or was it the psu I turned on his pc with his psu and it worked perfectly fine booted loaded into windows etc. When I put my psu in it just kinda broke it didnt boot anymore now he got the same problem as me it just spins and nothing displays did same things with his pc as with mine in hopes of fixing it but nothing worked I need some more ideas as of what it is



My pc specs are



MB: Gigabyte h77

CPU: Intel core i5 2500k

GPU: RX 570

RAM: 12GB ddr3

PSU: Be quiet dark power pro 850w

SSD: Biostar 120gb

HDD: Toshiba 1tb, toshiba 250gb
 
while waiting on @PeterOz and just to confirm

Connected the PSU to the display card?
Plugged monitor into display card?
Reseated the GPU?

Since you swapped the PSU into you cousins' system the same thing is happening and ever whit their systems PSU back in it still is doing the same?

was the PSU then only thing that you checked?

If you did not properly discharge you and the system could have fried it.
 
Yup psu connected to the gpu
Monitor is connected to gpu with hdmi
Gpu has been reseated multiple times

Yeah cousins pc started acting up as well even when I plug his psu back in

Yeah psu is about the only thing i checked but everything does spin to life like its supposed to Ill see to plug in his psu into my pc to see if it works or not I seriously doubt that it will

I dont know if I fried something might be the case but I dont think so I turned it off every time and waited a few seconds before taking something out
 
did you use the same monitor when testing both?
Can you try another monitor.
Power monitor off
Does your monitor have vga - if yes can you check via vga?
back on
only have kb and mouse connected
have power straight to socket no powerboards
 
I used 2 monitors while testing my own and an old one they both work display things so its not them used both hdmi and vga and yeah keyboard and mouse were the only things connected sometimes even without them
 
And yeah straight to socket did nothing also i just wanna say that the pc shuts off instantly when turned on with onboard graphics as the main source of display
 
when you setup your PC on the piece of cardboard, did you leave the GPU out of the equation?
also leave out anything not needed to get the PC to get past the POST cycle and at least to the Windows splash screen.
so no keyboard or mouse, no DVD, only one memory stick, no add-on cards like sound or USB3 ports, no peripherals like card readers or printers - that sort of thing, just barebones.
 
Yup cardboard with and without the gpu i got no additional pcie stuff it turns off instantly without the gpu with gpu it keeps runnin without displaying anything and yeah no kb no mouse not even the case it doesnt show anything no bios nothin
