hello all, im getting really low fps in all my games, and even windows 8 is self feels really slow. it all happened after a blue screen i had this morning, so im wondering if anyone who reads this and with similar setups can tell me what fps they are getting.

specs:
intel 3770k cpu not overclocked
h100i cpu cooler
Corsair Neutron GTX 120GB SSD
2tb western ditgal HDD
gigabyte amd hd 7970 gpu not overclocked
asrock z77 extreame 6/tb4 motherboard

games and fps:
starcraft 2 max settings 1080p: 40 fps gos lower lots
mechwarror online med-low settings 1080p 30 fps often gos lower too
thats the only games i tested so far.

and if you think it may be the blue screen that caused this (the lack of fps happened after one before i got good fps) please look here: BSOD on newly installed Windows 8 OS on my just built PC
and do you think reinstalling windows 8 would work?

so if any one can tell me how to fix and what fps they get on these games that would be great.
