Hi there everyone, I recently got a problem with my computer. It starts when after booting up to my desktop screen, a few minutes later the screen would turn into white. I suspect it might be my graphics card is faulty. So i decided to remove the gpu then at the same time I started to clean up my unit due to the dust build up inside my computer. After I cleaned up my computer using a brush, suddenly my computer won't boot up. I tried to test my PSU using a paperclip, connecting it to the green and black wire, the PSU fan will start spinning and tried to connect a molex fan, it would also turn on. But once I put back the PSU into my unit, then turn it on using the case power button, nothing happens, also tried to use screwdriver to jump start it, nothing happens. I also tried to re-seat all the ram and wires that is connected to my motherboard. Now I'm confused what would be the reason my computer won't turn, any suggestion or ideas? Thanks

My system:

Windows 10 x64
i5-3470
ASRock z77 Pro3
16 GB Hynix Ram
Gigabyte r7 250

I physically remove the PSU from my unit to test if it works using the paperclip method. Once it powers on and the fan starts spinning, I placed it back to my unit. Pressing the power buttons nothing happens at all. Yep already did that. I will try to borrow another PSU from a friend, hopefully it would works and I sure hope that it's not a motherboard problem.
Make sure the front panel wires are connected to the front panel pins on the motherboard.
Update your post to include full system specs and OS.

Power down, unplug, and open the case.

Use a bright flashlight to inspect all connections, card seatings, etc. very carefully and closely.

You may have knocked something loose or askew while using the brush.

Also: "But once I put back the PSU into my unit" - did you also physically remove the PSU and/or open it up?

The paperclip test is only very basic.

You can do more testing on the PSU if you have a multimeter and know how to use it. Or have a knowledgeable family member or friend who does.

Still not a full test per se as the PSU is not under load.

However if one or more voltages are either out of spec or nearly so then the PSU is suspect.

And, while the multimeter is present - check the power switch as well.

Hi guys just an update, computer now works okay. It seems that my PSU isn't my problem. Remove the motherboard again from the case, jump start it and the computer boots. The only problem that I encounter now is upon boot up, I encounter BSOD "Critical Process Died", I have tried to troubleshoot it using System Repair, tried to scan the C drive but still nothing happens, BSOD still occurs. What I did was to format my computer and it works perfectly until I install the driver for my GPU, the monitors suddenly display vertical lines and the computer won't function at all. Tried to restart it a few times then same things happen as before I can't get to the Desktop Screen as the BSOD "Critical Process Died" appears.

Re-format the PC again and go through the same process except now I'm using my iGPU, any ideas how to resolve this? Any time I use the GPU and install the driver of it, BSOD "Critical Process Died" appears. Thanks.
 
Also look in Reliability History and Event Viewer for error codes and warnings associated with display/GPU issues.

What source are you using for the GPU drivers? Hopefully the manufacturer's website.

You should also be doing a direct manual download to download, reinstall, and reconfigure the GPU drivers.

Not some third-party automated utility.

Read the download information very carefully to ensure that you are indeed downloading the correct driver version. All too easy sometimes to get the wrong driver through no fault on your end.

E.g., you find a "Beta" version or an older mislabeled version.

(Even more likely if you are not truly at the manufacturer's website. There a lots of "We have drivers" websites likely to appear via any search and the GPU manufacturer's name is present in some manner.)

Next step is to test a known working GPU in your computer or try your current GPU in another known working computer. Determine if the problem stays with your computer or follows the GPU.
