DEAD GPU? How to uninstall drivers?

[MattiasH]

Specs: i3-3220, GTX 660 1,5 gb, 6gb ram, 500w PSU, 1TB HDD.

Hi, under the past half year I've had problems when playing games. Sometimes when playing my screen goes black but i still hear sound and can type. And when i restart the i can see the acer logo and the boot sequence but when windows is supposed to pop up the screen goes black and I see a white line and many dots, colours around it. This has happened around 3 times by now and this problem seem to fix itself after a few days/week. I just purchased a gtx 1050 ti but I'm worried how i will uninstall the old drivers from my gtx 660, I've tried going into bios but i can't and I've tried putting a vga cable into the motherboard but i got no signal. Is this a GPU/PSU problem and how will i uninstall the old drivers if i can't see windows?

Use DDU to uninstall your current GPU drivers and reinstall the drivers for your GTX1050Ti with the latest found of Nvidia's site.

Can you please pass on your full system's specs inclusive of your OS?

I have upgraded from Windows 8 to Windows 10, i don't know how to see my full specs or use DDU, when i clearly can't access windows. This is the only site that has the exact specs as my PC, it's on swedish though so you will have to translate. https://www.webhallen.com/se-sv/datorer_och_tillbehor/168992-acer_predator_g3620-i3-3220-6gb-1tb-gtx660_15gb-windows_8

I did use DDU and reinstalled drivers 4 days ago.

Since you are upgrading from GTX to GTX just plug in the 1050ti and it should give you video output. Then you can do your whole DDU process. If you get no video output (that's usable of course) then remove GPU from system and then plug cable into motherboard I/O and your CPU embedded graphics should take over.

I tried plugging in a vga into the motherboard and to my monitor. But i got no signal when starting the pc at all. But don't i risk damaging my new gpu if i put it in with the old drivers?

The 1050 only outputs a digital signal, not an analog. A VGA cable adapter won't work. You need an Active converter that will convert the digital signal to an analog one.

I use DVI normally for my gtx 660 and i will use it for the 1050 ti aswell. I was just mentioning how the motherboard only supports vga for the integrated graphics.

As I said earlier make sure your GPU isn't inside your computer. No GPU at all then vga motherboard. And having the old drivers is fine. If the card doesn't recognize and use the drivers then it just ends up using the default windows ones
