I have last year bought an HP dv7 Pavillion notebook but due to personal problems I was not able to get my hands on it up until last year's December. It's an i5, has a ATI Radeon HD Mobility 5650 graphics card and 6GB RAM.

Now, the problem started when I was downloading the essential updates and stuff for my "new" PC. At first I tried playing Skyrim and Battlefield 3. Both of them asked me to update my driver, since my driver was quite deprecated. I then proceeded to the AMD driver update page. From there I downloaded the Mobility Catalyst Software Suite. When trying to run it, it outputted the following message:

AMD Catalyst Mobility cannot be downloaded due to incompatible hardware/software on your computer.

I then tried downloading the Catalyst Control Center. I am not sure what I actually did. I installed and uninstalled a bunch of versions. After a couple of tries it worked. I was able to play games.

Now, the main problem starts here. Yesterday I downloaded Mass Effect 3 Demo. When I tried playing it, something weird happened. The game looked like something taken from a PS1 game. The textures were blurred and everything was either too bright or too dark. But the main problem, FPS was extremely low.

I couldn't figure out why that was happening. I Google'd everywhere. Found nothing. I asked myself whether it was just a driver update issue. I downloaded the latest version (v12.1) of Catalyst and restarted my PC. I then tried restarting Mass Effect 3. At first the FPS had increased significantly (it was marking up to 60 fps). The graphics were still weird. But after a couple of minutes (hadn't even gotten to the tutorial yet), the FPS started dropping a lot.

I then tried playing Battlefield 3. I figured it was just the game's fault. I was wrong. The same thing happened to Battlefield 3. It was unplayable.

I started Googling everywhere. Again, found nothing. I then tried updating the Catalyst Software Suite. But as before, it outputted the same annoying incompatibility error. So I started googling ways to actually figure that error. I found a bunch of answers. Most of them told people to get the outdated HP graphical update driver, since AMD apparently prevented HP and Toshiba PCs to get the latest updates.

I am desperate right now. I don't know what the problem is. Saturday I was playing Battlefield 3 as usual (everything going smoothly). And now it won't even run Mass Effect 3 right. That problem came out of nowhere! Should I just get the HP update or what?

Did you get the driver from the HP site, Windows Update or the ATI site. I suggest only using the driver from the HP site as it may be that HP "tweaked" the ATI chipset in some way. I have seen this with Dell systems many times. Note that ther version may be "behind" what ATI lists

The general DV7 download page is DV7 Downloads

But, won't by installing the HP ATI driver disallow me to play any games that require recent updates such as Battlefield 3? – Renato Feb 17 '12 at 21:13
Possibly but if HP has tweaked the ATI chipset/Driver, that is what you have to use. You have encountered the "incompatible hardware" warning and that likley means HP specific drivers. – Dave M Feb 17 '12 at 21:18
Okay. I downloaded the DV7 AMD driver and tried the same games on it. I got really dissapointed. It's the same as before. I am starting to think nVidia has better products then AMD. I never had this kind of issue with them... – Renato Feb 17 '12 at 21:30
