I have a radeon HD 6950 that failed on me I think. I do not know what happened I just rebooted one day and it wouldn't print anything to the screen or seemingly go into the bios. After cracking the box open the error led light lit red for vga failure. So I removed the graphics card and plugged in one monitor to the integrated mobo graphics chip an i915 and everything worked and I was able to get to the boot loader and the quickest thing to boot to was a stand alone memtest+ so testing the machine I just left it running and everything was fine. Until I plugged in my other monitor. So I began to think it was the monitor not the GPU and I set the case back upright and plugged in the working monitor only to get the same problem. Which seemed odd so testing it I set the machine back on its side and the monitor worked on one booting and post failed on another seemingly arbitrary. To do some more test to the machine I used my TV and a HDMI cable to act as a monitor everything booted fine both laying on its side and upright several times. I then started up my system and have been stress testing with mprime for the past 4 hours no issues.
This left me with a question that maybe I had a bad cable or monitors but two at the same time seems unlikely.
So I am wondering:
1. if the graphics card had some issue and damages my monitors or my cables?
2. If it just over heated and went out could that damage the monitors?
3. If I have my power supply on a UPS could some sort of surge effected my GPU even if the rest of the system seems stable after hours of running mprime maxing the cpu?
Edit:
I ran mprime over night with no issues so I am wondering if the monitors or cables might be damaged and if so what would cause two to go out at once
