Good day! Let me start by thanking everyone about to read and help me with this issue! Its an odd one!
Originally I bought an Alienware PC it came with Radeon HD 6870. I soon upgraded to Evga Nvidia GTX 590, I have used it for about 4 years untill It begun overheating. Because of that I put the Radeon HD 6870 back in. The hardrive makes its usual sound, but the screen is black, there is no windows sounds so the windows is not booting up. Originally I thought that Radeon was simply dead and took it back to my friends house to double check, at my friends house the Radeon works flawlessly, it starts up and is capable of high end gaming without overheating. Now I suspected it may have been faulty powersupply not delivering enough power, I have tested two different once with same result, not to mention the one at my friends house was weaker Power supply then ether one of mine. OTHER videocards, I tested Nvidia GTS 250 and Evga Nvidia GTX 590 work fine, I also tested super weak radeon card with also worked.
Its worth mentioning that the Radeon does not work on the second PC i own ether, while other videocards do. So technically Radeon ONLY works for my friend, but on BOTH of his PC's!
Another thing worth mentioning that it doesn't seem to be a software issue, as we brought my friends Hardrive and plugged it in along the Radeon into my PC to no effect.
I did not make any upgrades to my PC besides a faulty soundcard. Powesupply was replaced at some point to exact same one from the manufacturer. I cant guarantee its not at fault, but would be odd considering more powerful video cards like Evga Nvidia GTX 590 still works.
I have uninstalled all drivers for fresh connect. I have tried using both of its dvi ports and its HDMI port. I preinstalled AMD drivers for a different radeon card, then connected it with drivers installed, to no effect.
In anycase I am completely out of ideas, the whole situation seems bizarre to me.
I will include my friends PC stats as well. I dont understand the issue at all. Considering the PC originally was build for that videocard AND it works for my friend.
