PC stopped working mid-use - now won’t display anything

I was using my relatively new build (delivered 28/05/22 - specs below) and mid-game a bunch of green lines flashed up across both monitors and the pc appeared to crash. Lights were still on and fans still going but no sound or display.

Attempting to restart, it powers up as usual, and the PC Specialist logo pops up, but with the added green lines across the screen (see photos attached). Rather than booting windows, the screen just turns black before the monitor indicates there is no signal.

I have tried plugging a monitor into the motherboard with the same result. I can open the bios and it displays fine, but when I attempt to boot, I get the same green lines.

Dealing with Image uploads and files to the site

Hi all A bit of a helpful pointer should you wish to post images to the site. The maximum file size of an image you can upload is 1MB. It's quite normal for photos to be above this size, but there's an easy way to shrink down the file before uploading. Download Gimp. This is a free open source...

Once you're in Windows do you get the se lines? Can you upload a screenshot of the windows desktop?

It doesn’t get to booting windows, after the PC specialist boot screen I just get a black screen - tried this with both monitors plugged in individually

If you plugged monitor into the motherboard (and therefore using the CPU onboard graphics) and get the same result, that sounds like an issue with monitor or the cable. I'd doubt both the GPU and CPU have the same physical defect.

Can you try using a different cable, or test the monitor connected to a different device like a laptop?

That's a very good point, I'd missed that

Thinking further, if the BIOS displays fine, and the green lines appear when windows starts to load, it could be a driver issue. And the fact that you saw it both on GPU and CPU could be if Windows is using a generic VGA driver during boot sequence for both inputs.

In which case, booting from a USB drive with windows recovery image, might allow you to boot in safe mode and correct the driver issue?

The logon screen is outside windows so there is no driver in use

It's not until after login the driver kicks in

There has to be some driver used, even if it's a generic/standard VGA one? And the login screen can't be outside of the OS, it's certainly not part of BIOS.

No, no driver, it's the hardware BIOS connection at that point, no software layer until you're through logon.

Well there is a driver bit it's a generic driver that works with any hardware.

Silly question but have you tried reseating the card or trying another PCie lane?

I had a similar problem years ago that turned out to be a faulty connection to the PCie lane and worked fine in the second slot

So the boot squence is BIOS (POST), then the Windows Boot Manager, then Windows OS Loader and then Windows NT OS Kernel.

So once past POST, it's the OS (Windows, Linux, etc) that continues the boot process. My thinking is that the generic VGA driver loaded as part of Windows OS Loader or OS Kernal step is corrupt and causing the display issues.
