find and download MalwareBytes Anti Malware
run a full scan
Edit: try HijackThis to scan, it goes through hidden files too
if nothing is detected, it may be a networking issue
malwarebytes found hotpotato (random adaware program, pretty useless)
hijackthis found ask toolbar, nothing else (not really dangerous)
did rootkit scans, found nothing
avast detected ~4 trojan downloaders (possibly blocked them before they installed, and they were the same. probably tried to keep installing itself) a few days ago, i'm pretty sure this is related to the problem and probably damaged some files or registry keys which is slowing down your computer
since it drops fps in many game, i don't think its a network issue. i checked quick and nothing was changed for his network settings
ran speedfan, normal computer temperature
you're pretty much due for a reformat, you have a lot of crap on your computer

take a day that you have nothing to do, save all your files/folders (that you need) and reformat
i'm all out of ideas, sorry about that. if you experience any other problems that could help me identify the problem, that would be great
