Graphics Card: MSI HD7850 OC 1GB
Driver Version: No driver right now, tried 12.8, 12.9 Beta and on CD MSI driver which I don't know what version.
64Bit Windows 7 SP1
3 GB DDR2 RAM
3.2 GHz Dual Core
500 Watt PSU (43A on 12V)
Gigabyte 945GCMX-S2 motherboard, bios version F5 (supports PCIEx16)
HP 2310ei monitor.
I bought and installed this card today. There are almost always artifacts. It's like they appear on some colors only. In bios there are two columns which writings under them appear greenish instead of white. Since bios starts at a low res, there are only two big columns of artifacts. But when Windows starts artifacts get smaller in windth and appear more frequently. There are like 15 artifact columns and 15 problemless columns. They are always there. They just dissappear on certain colors but they are there. They are columns of reddish/greenish lines stacked on each other.
Now that you now the problem, here is what I did to solve it. Obviously first thing I wanted to do after installing the card was trying to install newest AMD drivers (12.8). It installed normally and asked a restart. After restart in bios artifacts appeared as usual, but this time after Windows' welcome screen came, it was incredibly full of artifacts. It was like color fest of dots. "Welcome" dissappeared and then black screen appeared. And then nothing.
After a restart same happens. So I go to safe mod and windows opens but with same old artifact columns. So I thought drivers were making it worse. Decided to install MSI drivers from CD. After all that driver sweeping and restarting session, I opened Windows normally without drivers and artifact colums were there again. Installed MSI drivers but they didn't include CCC. I restarted anyway (even though it didn't ask for it), but nothing changed. Device manager was showing "7800 series" with a warning that says I needed to install drivers.
After failure of not starting Windows with 12.9 beta drivers, I'm trying to decide. Am I doing something very wrong here and it's not working, or is my card bad? I had an Nvidia card before and I didn't uninstall its drivers at the time I first I installed the new AMD card. I thought that was causing some problems but I swiped all remains of it, yet it still doesn't work. When I return to my Nvidia card it works without any problems. So I don't think it's motherboard or PSU or bad PCIe slot. But you never know.
I bought the card just today, so if it's the card that's the problem as I decided, I want to return it as soon as possible.
Right now probably only thing I didn't try is installing 32bit Windows 7 with a format, but I'm negative that it'll be any help to me so I don't want to try it.
Btw I can't see if card is overheating or anything since I can't install drivers and I can't monitor its temperature. As its name suggests, I think the card is overclocked a little by default (maybe not, I'm not sure), but I don't think it can cause this many problems.
Edit: I forgot to mention that my ATI driver folders appear empty when I install a driver.
