Hello, thanks for reading the thread...
I have a Phenom II 965 BE at 3.8gHz, 8 GB of 1600 mHz and a HD6870 a bit OCed (don't remember the actual number, but was not insane)... The PSU is 600W, and MB is an ASUS M5A87
Now, this rig has been rock solid for months, never ever had an issue once I got the numbers right... Not a single artifact, or reboot, or anything like that... It always worked OK...
But 2 days ago, while a was playing a GPU intensive game, screen started showing weird stuff... Thinking it was the game (since I'm new to that game), I ALT-TABed... I went right back to W7's desktop, everything was ok, no artifact (1080p)... I thought "oh ok, it's the game"... I tried to re-enter the game to close it properly, and could not recover from it... Screen froze...
I rebooted my PC, and nothing bad happened until I logged to windows... I did see everything ok, no artifacts at all... But as soon as I logged to Windows, issue appeared again and computer froze..
In the following reboots, artifacts started to appear in the first thing monitor showed, and also are present on the BIOS screens... (no drivers involved, so we are at the HW-issue level)
After initial trouble shooting, I determined that what caused the freezing was the resolution of the screen... So I managed to lower it by disabling the GPU in safe mode...
The problem I have now, is that even though I can use the PC, I cannot use the GPU properly...
Artifacts are present constantly (mainly, horizontal green lines)... But also, it seems browser is having issues rendering pages correctly.... Please, visit http://www.windguru.cz/es/index.php?sc=261 to see how it's supposed to look like (it's a weather page)... Now, see how I see it...

It also shows like that (no colors) if I use team viewer for instance, but I do not see the artifacts (Green lines) on teamviewer... Other pages also present issues as well...
I've also tried removing the GPU from the MB, and computer seems to boot ok... I can connect by teamviewer, but graphs do not actually work (desktop seems to have issues rendering with no GPU installer)...
I've also removed RAM modules just to see if those where causing issues...
So, what's my doubt?... Well, it seems it's a GPU issue...
But I wonder if there's any other way for me to rule other suspects out.... Because I don't really want to buy a new GPU (a bit expensive here in Argentina) only to find out that the PCI-E slot has gone bad for instance, or I have a faulty PSU (i do not think it's the PSU although)...
Sadly, I do not have access to spare parts... That's why I cannot test another card on the SLOT...
Thank you!
