HI,
I recently had a problem with my computer. For the past two days its been running slower than usual and and games are very laggy! i could play skyrim, dead island and all those games easily with medium to high settings. Now i have to put it all the way down to low to play them.Also something else i noticed is that the Text and writing In-game is a little blurry(just to put it out there)but the text on google chrome and other programs are fine. It was working fine for about 3 months, but now its slow. :( Anyone wanna help get rid of this problem?

My specs:
Amd athlon II X3 445 Rana 3.1ghz
Hd radeon 6570
OCZ Modextream 750W
Windows 7 ultimate 64bit
2x4gb memory

Please help! :)
Thank you,
