Ok so I got my pc around feb this year, i dont know much about computers, only basic stuff. My computer is slow despite having an nvidia gtx770 gpu, 4gb ram, and an intel i5 processor, im not sure if this is a hard drive problem or problem with windows? Lots of my steam downloads are missing logos and warthunder(a game i downloaded) doesnt work, when i click on it it just says:
Unable to execute a file in the temporary directory. Setup aborted. Error 5: access denied.
Also i uninstall avg ad all of the files are still there and i cant delete them. I cant save anything onto c: drive when i choose to and also when i play battlefield even on low settings it lags and the games im in often suddenly end with some error message coming up. Sorry for this big list but its just really annoying me how unpredictable this is, it seems there are new problems cropping up all the time. SOMEONE PLEASE help me, could someone give me a step by step guide of what to do? Thank you doctors of the computer world!
oh yeah ps im on windows 7, 64 bit
