What could cause my GPU to crash after boot?

[Frandesktop]

I bought Thermalright Odyssey thermal pads (1.0mm) for my old R9 290.

I found an old post from this forum with this image:

 

Now I noticed some are more than 1mm, but I still used 1mm for all of the chips

 

The PC boots and displays everything and I can play in BIOS without issues. But as soon as Windows boots, it crashes. Black screen. The screen doesn't turn off, it just turns black (still illuminated).

 

If it works without issues on BIOS - why does it crash with Windows? Or, in BIOS it doesn't require too much energy and doesn't get heated and as soon as Windows loads it heats too much and shuts down (because I did something wrong - VRM pads / Memory pads / thermal paste?

 

The problem is I can't get into Windows to check temps

Cut the power while Windows is loading, so that it detects a problem with startup, so you have the option to choose Safemode next time to start the PC. 
If you're able to enter Windows Safemode, it could be a  simple graphics driver problem. Then DDU the driver and try reboot normally.

Try going into the safe mode or try to reinstall windows also make sure that your card is live and there is no problem with your bios.

Thank you guys. When I spread the thermal paste (MX-4) which is non-conductive, quite a drop fell on the little resistors (I think?) around the die. I know it's not conductive, but could it still cause issues somehow?
