Windows 7: Sudden poor performance in a decent computer (Win 7 64-bit)

Sudden poor performance in a decent computer (Win 7 64-bit)

Hello all, and thank you for reading. I will try to keep this brief, but I'll try and explain my situation as clearly as i can. Recently (Thurs/Fri) I began experiencing a sudden drop in performance in nearly every facet of using my computer. Mind you, its not a severe drop, but enough to make gaming and media experiences frustrating. A few examples: poor response on anything media related, in particular youtube, an extreme increase in load times on games such as League of Legends and Torchlight 2, and a very noticeable drop in framerate in said games, and also (for lack of a better description) a general lagginess when web browsing or otherwise using windows. Im relatively experienced with computers, but definitely not a pro. I did have one BSOD earlier in the week, but thought nothing of it as my computer had been on for at least a couple of days, though that isn't the norm for me. I have beat the internet up, down, and sideways for a solution in the past 48 hours, and frankly i dont know what else to do. Here's what i have done. Downloaded HWmonitor to check voltages and temps, downloaded HD tune to make sure my HDD is functioning properly and not trying to quit, downloaded and re downloaded several different Spyware programs to check for malicious activity which I ran in safe mode, scanned and rescanned with AVG to check for and malicious activity, opened my case and checked every single cable and port to ensure positive connections, unseated and reseated my GPU, ram, and graphics card to ensure positive connection, blew out and cleaned dust from the inside of my case, checked all fans to make sure theyre operational, and even ran /scannow in an admin cmd prompt. In the process of trying these different options I used League of Legends as a benchmark, as I reliably get 60 FPS through an entire game, regardless of graphics strain. Lo and behold, when I tried to run it this morning, I get a game crash in between loadscreens. Rather, the game just doesnt load. I tried to use Starcraft 2 instead, and run into the same issue as it tries to update. Whether this is important or not i have no idea. I have steam and AVG running in the backround, nothing else. Ive kept a close eye on my task manager processes to see if I could find a memory hog. After i finish writing this, im going to set Memtest running and get some sleep. If anyone has any ideas/tip/tricks/witchcraft, insight would be wonderful. Thank you for your time, and apologies for the wall of text.

Hmmmmm....... you say you've ran more than one malware scan and a anti-virus scan. I would run a sfc/scannow first to check for any corrupted system files. (see link for tutorial) But simplest things first. Have you tried a restore to before this problem started? I would also look to the drivers for your graphics card. Either uninstall and reinstall or rollback to an earlier one if you've updated it recently.

SFC /SCANNOW Command - System File Checker

Graphics Driver?

If your problem is mainly graphics-related (games and videos) have you tried uninstalling and doing a clean reinstall of your graphics driver?

When I had an NVidia card and I downloaded driver updates from their site, the updates had a clean install option.

Windows recently offered me a Fresco Logic USB 3 driver update.
I foolishly allowed Windows to install it and it caused all sorts of havoc on my PC.

Uninstalling the update and reinstalling my original driver didn't fix the problem.
I had to use my backup W7 image to re-image my W7 partition to fix the problem.

Poor computer conditions = poor gaming performance?
First off, I didn't know whether to post this in gaming or hardware. Sorry. My question: If there is dust on the videocard and fans or other poor condtions in my computer, can it affect performance in gaming? FPS wise? Thanks, Andrew.
