I am not sure if this is the right sub-forum, but I don't think my problems have to do with an infection and I have no idea where else to go.
I have a Windows 7 64-bit PC with the following specs:
proc: AMD phenom II X3 720 2.8 Ghz
GPU: ATI radeon HD 4800
HDD: SAMSUNG HD103UJ
I booted up my PC this morning and everything went fine. I start up a game and for some reason all of the text in the game became unreadable and disappeared for 80%. A quick restart of the game fixed this (I have no idea if this is at all related, its just something weird that happened as well). After that I tried to go on Reddit and watch a Youtube video, and for some reason the audio and video keep stuttering, but my internet connection is perfectly fine and has no problems loading at all, and the video keeps playing at the same rate, but the video and audio keep stuttering. After that happened i tried a second game and the same thing keeps happening there.
I have no idea what can cause this, any help is welcome. If you need more info to help me i'll glady give.
Edit: I forgot to mention I recently re-installed windows 7 on this machine (with full hdd wipe) because of earlier performance and malware related issues. I am probably still missing some important updates for flash/java/windows etc.
