I've defragged the crap out of my hard drive (several times over until it only got to the point that each defrag took less than 2 minutes and no more progress was visible) and run CCleaner and Eusing Free Registry Cleaner. I've updated my GFX driver to the latest version and rolled it back to a few different 18x.xx drivers just in case, but that didn't improve anything. I ran Intel's processor diagnostic and it said my processor was fine. I've run Seatools (all the scans it has) and all of them passed. My temps all seem normal and all my fans are running at their regular speed. Nothing major was found, except for one rootkit with tdsskiller, which I removed. I've scanned for viruses with Malwarebytes, SuperAntiSpyware, AVG, Avast and tdsskiller. I didn't change drivers or make any drastic changes to the software or hardware of my computer. After lagging for a few minutes, it simply crashes to desktop.īefore this, I could run all the games mentioned maxed out and achieve 30 FPS or more and had quick load times. And, most importantly, New Vegas runs perfectly fine at my regular settings - but as soon as I shoot at someone, the game becomes a slideshow. Battlefield Bad Company crashes to desktop about 15 seconds after joining a server and runs really slow during those 15 seconds. Borderlands runs fine for a few minutes, then starts to lag out horribly down to what seems like 5 FPS or less. World of Tanks and League of Legends take an eternity to load a level.

Also, my games have all showed weird signs of this slow down. It BSODs if I have more than 8 or so Google Chrome tabs open - that's how bad it's become (previously I never reached a limit that made it crash even with 30 tabs open).

My computer's suddenly slowed down a lot lately.
