Question Gpu crashes when i removed second gpu

[Makatas]

I was running two gpu two monitor set up since i upgraded my gpu few years ago, and since i didnt really have any use of the older gpu, i just plugged second monitor into it and called it a day and it was fine for years. Recently i sold that older gpu and my problem started since then. Using pc everything just crashes, video completelly stops,but sound works for few seconds, then after few seconds sound also gets stuck on the note it was playing at the moment of the crash and just scream that note entire time. It happens more often when playing games, but its not unusual to crash when just websurfing. Im geting video tdr failure - nvlddmkm.sys blue screen, but as far as i understand it only tells that its indeed gpu who stopped responding. I tried running two monitor set up when main monitor is hooked to my gpu, second monitor hooked to integrated gpu, i tried single monitor set up, that didnt help. Any ideas?

Wild idea came to my mind after weeks of expierencing this. I decided to put my gpu into another pci slot, where my previous gpu was. So far im 3 LoL games in without a single crash. Can it be pci related?
