- XFX Radeon 6870, Model # HD-687A-ZN

AMD Catalyst Driver Version, and Driver History
- 8.782W (came with XFX card on CD)
- Microsoft Windows 7 64-bit, Build 7601, Service Pack 1
- I first experienced video problems two days ago while playing Counter-Strike: Global Offensive (running at maximum settings at 1920x1200 but with vSync off, mouse acceleration off and raw mouse input settings on). During the game, the screen just split in two and the two halves were switch. In other words, what was on the right was now on the left side of the screen and vice versa. Then the screen turned black BUT sound was just fine and I could still hear everything normally. Now I can't do anything else because I get the black screen when I try to log into Windows normally (after entering my password and waiting for the desktop).
My Attempt to Fix this Problem
-I followed the FAQ instructions from my graphics card brand, XFX, on their website and now the screen turns black before the login screen when booting normally. I can only use my computer in Safe Mode. With all of these driver versions I've tried, I have installed the whole ATI Catalyst Suite and also the drivers by themselves.
-I have even started Windows normally with only core drivers and services running and it has not helped. Sometimes with different settings I am able to log into Windows normally but after a few seconds I might get a black screen (or on two occasions, yellow vertical lines). During the time it works I am able to navigate Windows and SOMETIMES use the internet but the Aero theme is not available.

Display Device(s) and Connection(s) Used
- Hanns·G HH-281HPB Black 28" 3ms
- The GPU is connected to the monitor using a VGA cable (my monitor's two HDMI ports are defective and only the VGA works so I'm using a DVI-VGA converter on my GPU's end). At first I thought the VGA port gave out and it was finally time to get rid of this crap, but I don't think this the root of the problem since I had the same issue using a DVI-HDMI cable on another screen (HDTV) . Also, this setup has worked fine for 3 years.

Other things I've done:
- The FIRST thing I tried to do was use System Restore to restore to an earlier point. However, I noticed that System Restore was disabled without my permission and I have no restore points. Assuming this was the result of malware (this happened to me earlier this year) I ran a Norton 360 virus scan, a Spybot S&D scan, and a Windows Defender scan (Safe Mode if possible, otherwise in normal Windows). All of them found nothing. I also removed any suspicious software from my Add or Remove Programs list. However, please keep this in mind. I'm concerned malicious software may have started this.
- I started windows in low resolution mode and it did nothing for me. It was like running in normal Windows which meant that this option led to a black screen as well.
- My only hardware swap was with the screen. I already used my computer with another screen (my HDTV) and I got a black screen anyway so this is not a monitor issue.
- I have reinserted the graphics card, my RAM sticks, and all cables connecting to the back of my computer case just to see if they were loose but this hasn't helped.
- I have cleared the CMOS memory using the jumper on the motherboard.
- I've attached three screenshots to this post. The first one shows the black screen with yellow vertical lines that I saw twice this morning. The second screenshot shows pink horizontal lines going across the BIOS screen which was very odd. The third screenshot showed an error message I received when repeately tapping F8 to get the menu with the Safe Mode option. I got this a few times and just hit escape to get past it.
Please assist me and let me know if I need to replace any hardware. Thank you.
