Well it isnt fixed and ive restarted it manny times.. And now the internet is also slow.. But it isnt just for my computer all the computers have the same.. But when i looked at the thingy that checks my speed it says 8-9mb/s wich is normal for us :/ so may it been a hacking program or something..? And some pages loads like Really quick.. And some does not like this page loads in seconds and facebook loads in ages.. :/
Hey.
Make sure you check your Network settings, just to double check anybody inbetween your area, ins't stealing your internet.
Secondly, clean all the crap you have in your PC. It may sound that it wont help but, from personal experience, YES it does.
Thirdly, if the problem still occurs, make sure you don't have any background applications running whilst you play SA-MP, for example, Utorrent.
CCleaner and GameBooster are two good programs which enable you to clean your PC throughoutly.
Hope I helped.
