Please help, assuming either psu or gpu

So I managed to get a new moniter, went from a 1368x768x60 to a 1920x1080x144, and it worked perfectly for the first 2 days, then this started to happen.

I now have to restart my computer a couple of times for it to work, I'm using a AMD R9 260 I think, unfortunately I'm at work until this afternoon, will update with full specs then, hoping someone know something of the top of their head by then.

Thanks in advance.

Actually a 270

My gpu

uninstall video drivers, use driver sweeper.
if still fails then card is borked.

card has a 2 year warranty.

Wow, such a simple solution, thanks for that.

You removed my worry of dishing out for a new card.

Hmm, you might have a faulty GPU, but try above first.

What's your system spec including PSU make and model.

I had something similar which looked like this https://i.sli.mg/xSQBab.jpg

but a total freeze with audio looping and only when in a game for a few mins, it turned out that it my GPu was overheating , needs new thermal paste.

check temps just to be sure, but it's likely a heat thing upon booting windows.

check your cable too, and swap the card into another PCIE slot, even if it's 4x 8x.

If you have integrated graphics try that.
