This is posted in this section because the graphics card seems to be where my problems are.
While trying to persuade my dad to buy me a copy of Windows 7 for my current computer, I've been using my friend's [pirated] copy of Windows 7 64-bit, which obviously means no updates. If I can't persuade my dad I'll have to go back to XP 32-bit, which is ok, but I much prefer 7.
It was going fine when I was using the W7 disk from my dad's laptop (Dell OEM disk) until the activation period was up. I didn't want to risk the laptop's copy being deactivated, so I borrowed my friend's cracked CD till I could get a legit copy. Everything worked fine, but I started noticing my framerate in TF2 was dropping periodically to about 1fps, and my ping was going up to about 300 (from 40 or so). It's not my network - every speed test I try gets a consistent 10Mbps download speed, the same as it used to.
I then checked Catalyst Control Centre. There were literally no options I could change for my processor (Phenom II X2 550 Black Edition) or my graphics card (Palit 4870). Graphics Overdrive is apparently turned on, but I can't change any options, and the switch for CPU Overdrive is greyed out. I downloaded AMD Overdrive (the stand-alone program) and it recognises and can tweak my CPU, but completely ignores my GPU - every box in the "GPU status" panel has a grey zero in it.
So, I uninstalled all AMD drivers for my graphics card from Device Manager, and then downloaded the latest ones. Nothing. I downloaded CCC 11.10, to see whether I just had an older version before, and the 4xxx series had stopped being supported in Overdrive. Still no results.
So my question is: What do I need to do to get it working (till I get legit W7)? Do I need to get older drivers, or is there a driver uninstall I missed somewhere, or is the only solution to put XP on here? Any help or advice would be appreciated. Thanks.
