Hi Guys,

Hear me out, I do not know whether my GPU or PSU broke down. Yesterday, I powered of my PC to eat lunch, when I came back to turn it on, my dilemma began. It is not powering on, or even booting to bios, no beep sound and no display, but the fans were whirling. I checked the cables to see it is just a wire problem...nope. Monitor problem..nope.

The monitor cable was connected to my GPU(ASUS GTX 650Ti), so what I did was, I connected my monitor to the onboard Graphics and it powered on.


Here is my question. How do i differentiate between a GPU problem or PSU problem. I was thinking like maybe the GPU is not getting enough power from my PSU.

PSU: Cooler Master Thunder, 620W.


TIA, Cheers!

This might not be a GPU or PSU problem. If your computer won't even boot into bios it means there is something wrong with your motherboard. Mobo's can just break down without warning (fans can still be running because power is still being supplied but part of mobo can already be dead so it wont work such as controller chips and stuff)

When your PSU is failing (cannot deliver enough power) you'll notice occasional hang and freezes on your computer when its trying to run an application. --> This is like overclocking your CPU but you didn't set your voltage high enough to provide the needed power and when you try to run things you'll freeze and hang.

If your GPU is having problems you'll notice artifacts (white spots and weird discoloration that should not be there) and you might occasionally get weird vertical or horizontal stripes across your screen. This can happen too with GPU memory chips failing.

Hi meat_loaf,

thanks for responding. As I have stated, connected my monitor to the onboard gpu, things went ok, so i am guessing that my motherboard still works,yes?

If i connect my monitor to the GPU, it powers on. but there are no display. I forgot if i heard a single beep(which tells us its good right?), does that mean it is a GPU problem?

Whatever the beep means you have to refer back to your mobo manual. Every mobo/manufacturer has different way of telling the user what the beep means and I don't know what it means in your case.

If you are using on-board gpu and it powers on with no display then you have go to the bios and set the display adapter to onboard since it might have been set to PCIe. Normally the computer should automatically detect, but if it doesn't then just reset cmos by taking out the battery of the mobo.

i think you misinterpreted me ;) 

OnBoard GPU = OK.

Discrete GPU = Not OK.

I think ill test my GPU to my friends unit. Thanks man.
