Hello.
I have a GTX 770 for about 3 years now. Suddenly approximately 1 month ago I started having issues with it.
Sometimes the display will go black while the PC is still on and I can hear the sounds and everything.
Only thing I can do is reboot from the button and when I do it won't restart. Instead the fans work at 100% speed and very loud (I have the gigabyte windforce version) and it doesn't seem to recognize the GPU. I tried to leave it on but boot from motherboard instead of gpu and with the GPU monitor gadget that I have I could see that the 770 was not detected.
I thought I will have to get a new GPU so I was read to go for a gtx 1060.. But I thought to myself...
If it's the GPU's problem, then why does it work sometimes?
I can play a couple of games fine with no fps lag or anything. Just sometimes it decides to die.
Could it be that it's not the Graphics Card problem but the PSU's problem?

P.S. Sadly I do not have a speaker to know if it makes a beep sound or not.
