Only 3 days to go! erm..... if anyone else has something to add please do so! Recently i been cleaning my PC externaly and internaly. I recomend you do so too! Use free software like Lavasoft Ad-Aware to clean any nasty unwanted adverts and trackers! I also recomend you defrag your Hard disk before you start playing HL2. and also RAM defrag. (also free software) Finally software such as norton system works. Although not free it is very useful in cleaning your PC and making it run more efficiently. Clean your keyboard/mouse too to make movement smoother, also your monitor. A good clean can help to make the visuals clearer!
