Hello!
I have a pc with ATI HD 7700 GPU and it has a very strange problem.
After Windows 10 loads, when the user loading screen should appear, there's no video signal. This only happens sometimes. I have to reboot many times until video just works and everything is normal. I tried to plug another monitor when it said "No signal" and the other one said the same thing.
I tried to format and everything gone fine for 3 months. Then the problem appeared again. After many weeks it happened more often. If at the 3rd month it needed only one or two reboots, after weeks it needed 6 or 7 to make it work. When it says "No signal" the PC remains ON.
THINGS I DID:
I updated BIOS (2 times) and I updated drivers but nothing happened. I tested HDD, RAM and CPU. During CPU test PC freezes after 30-40 min.
If i use a different GPU (I tried two) everything is fine. I also tried the same GPU (HD7700) in another pc for days and everything was fine.
So the problem seems to be this particular GPU in this particular PC. Any ideas on how to solve this and what the problem really is?
