I recently decided to join this forum as I constantly find it in my Google searches for computer issues and it helps a lot! As such, when I couldn't find my solution, I figured I'd ask you guys.
So here's the issue: since the past few days, every game I play has had MAJOR framerate issues. I thought it might be the game I was playing (mostly League of Legends), where my FPS suddenly went from 60 to 15 using the same settings I'd been using for months, however, when I tested that theory against less GPU-intensive games such as Super Meat Boy or Limbo or recently even Black Mesa, I had the same issues--a huge drop in my FPS. This leads me to believe it might turn out to be a hardware issue.
Before I go on, let me post some of my specs. These are directly copied from my DxDiag file, since I don't know how to post screenshots yet.

Along with this dedicated graphics card, it has the basic Intel HD integrated graphics. I've tried several things, such as changing settings, messing with BIOS settings (which I've undone), running benchmarks, and running GPU-Z. The temperature is normal; it LOOKS like my computer uses the ATI card over the Intel while gaming. However, the issues I am experiencing are similar to those I experienced before I had the ATI card, with the low FPS across the board. Because of this, I'm wondering if it might be that even though everything I run tells me the ATI card is being used, it might actually be the Intel? Of course, I have absolutely no idea.
It may also be pertinent to note that I recently tried to install Comodo Firewall and immediately uninstalled as it created network issues for me. I have scoured my computer for any drivers it may have left behind, any registry values, and any folders or anything at all the software may have left behind during the uninstallation. The reason I mention this is that before this, things seemed to work just fine. Once again, however, I have no idea if this is it, since for a number of days before I noticed the issue, I was unable to play any games due to having to wait for support tickets to be responded to from Riot (League of Legends) and Steam, which would allow me to log into my accounts. However, back when I was able to log in a few days before those issues, the FPS issue was nonexistent, at least in League of Legends. I couldn't tell you more about the Steam games since I didn't reinstall Steam for quite a while. I recently had my laptop shipped in for repairs, and my motherboard was replaced, though the gaming seemed to work fine when I got it back. It isn't until I didn't play for a few days and got rid of Comodo that I started noticing these issues.
