Hi, im new here, I have just looked for posts that would solve my problem but found nothing. I got a nice computer (hardware listed below), I used to use windows XP, I could do anything without any problem. I installed Windows 7 yesterday and thats where my problems started, now I can't even play League of legends which i used to play on 60fps, now it runs on 3fps, watch videos on youtube on full screen also goes laggy, sound messed up and video on a low fps(I have no problems with videos in my HD nor youtube videos not full screen), it made me think it could be my internet connection, but I download torrents full speed. I hope someone can help me. Intel Core 2 Quad Q9400 (2.66GHz) RAM: 4GB DDR2 800MHz Graphic card: NVidia 9500GT 512mb Windows 7 32bits 250GB HD Seagate SATAII Edit: All my drivers are up to date.
