I want to preface that I'm not very computer literate. I know the basics, and was able to build my current computer (with someone's help), but sometimes stuff can go over my head so bear with me.
Backstory: I have a computer I built about 3 years ago, a friend of mine picked out some parts based on what I "wanted," really the extent of what I knew about my computer was that I have 8 GB Ram, 4 cores, etc. That and I had a gigabyte HD Radeon 5570 that more or less ran everything I wanted it to perfectly. I had and still have Windows x64 Ultimate. The card died about a month ago, I bought a new one (an Asus 7750) and I got my visual back. I had uninstalled the old card's drivers
and decided to do a clean install of Windows (Sort of an impulsive idea, I just wanted a "fresh start"). I then Installed the latest release from AMD for my new card. (Granted, I BELIEVE I uninstalled the old drivers. What's the easiest way to check?)
I'm a big gamer so my new game I was playing after the switch was Dead Space 3. After a while I noticed that if I was doing something in game that involved a lot of movement (doors closing, screen shaking), the game would freeze. The game would stop and the visuals would be frozen, but sound would continue. It didn't crash to desktop, just hung there. I tried uninstalling and reinstalling different drivers and older, more stable catalyst suites, nothing seemed to work. I went back to the latest and just swallowed my pride: I finished the entire game just restarting the times it would stop, maybe 2 dozen total. It bothered me that the problem seemed "random;" even if I noticed that it would mostly happen in high action sequences, sometimes I would make it through an area without a freeze, sometimes not. As you can tell, I'm pretty bad at troubleshooting. I just assumed it was local to that game's having, I don't know, poor coding and my Frankenstein of a computer didn't like it. Yeah, not exactly scientific.
Anyway, now I'm trying out the new Bioshock Infinite, with the latest drivers, and just an hour in the exact same thing happened. Visual freeze, game stop, hang unless I stop the process. This time I checked the catalyst suite's provided information as I was running it, and I didn't notice any obvious overheating or fatal errors despite the game failing. This second occurrence makes me think it's not a problem that will just go away, as childish as that sounds.
I know it's not a lot of information to go on, I was hoping maybe someone had a similar issue, perhaps with the Radeon 7750 card. I'm hoping that I didn't get a bad card (I ordered all the parts for this machine, past and present, from newegg.com). I can figure out all the other components I've got if need be, but I'm hoping that since the only big change is the new card that the problem lies there.
Thanks for listening, though.
