First of all sorry for my english.
Well I have my current computer for about three years now and had a hd 5450 in the beginning, than about 2 years ago I swapped to a hd 6870 which is what I have now and never had any problems with it until recently.
My problem is that about some days ago I was sufing the web like any other day, when suddenly my pc crashes and freezes, the screen got all green, and I had to restart the pc. And now it wont boot past windows welcome screen. The bios boot normally, but when it comes to windows welcome, I get some black & colorish horizontal lines though the sceen, although u can still see the blue from the windows 7 screen. When its about to load the desktop, the screen goes black and does not give any signal of life, forcing me to restart the pc, coming back to this looping situation, although my computer works fine in safe mode or when I disable the graphic's card driver from windows (because my mobo does not have onboard graphics, I am forced to use my HD 6870 connections for video, so at least the problems is not its connections), so I can use the computer, but with the graphics card turned off, using only its dvi connection for output, with low resolutions and bad performance of course. But as soon i activate the graphics card's drivers and reboot, I go back to the black horizontal lines.
And well, coming to solutions, I have tried everything I could possibly think of; cleaned the graphics card, changed its pci-e slot, used hdmi cable instead of dvi, used different dvi ports, reinstalled the most recent drivers from amd, cleaned registry, swapped the pci-e power connections, cleaned the pci-e slot being used, used default configuration in bios... Just didn't format my hd because i got about 1tb worth of data and from my opinion its clearly an hardware issue, having nothing to do with drivers and/or windows. I have not recently installed anything new in my pc, nor installed any new sofware or driver other than my effort to reinstall the amd's drivers. Its not about overheating, as i checked the temperatures are normal as always , and all fans are working. My power supply is more than enough (probably even double the needed wattage, pc specs bellow). I use my pc for surfing the web and mainly heavy games, like bf4, dota 2, skyrim, assassins creed, crysis etc so my HD 6870 has been heavily used thoughout the years. Also, from my conclusions, using my pc for more than 2 years now, not having anything new installed or changed, and suddenlly having this issue, I think the problem is in the graphics card which is getting old (although i have friends that use 4 year old radeon graphics card without any problems), and you can even discard the possibillity of uncompatibility between the hardware. I don't have anything overclocked at all, everything in default clocks and voltages throughout the years. My bios have been updated to the last version avaiable since last year.
tl;dr
sudenly my pc crashes and now it wont boot past windows welcome screen with strange horizontal lines though screen.
