Stumped

[Hamer]

Yeah im not quit sure whats goin on, ive cycled my modem, still no internet, but upstairs (which is wireless from downstairs) works as you can see. Plus by BF:V is acting up too. Sometimes when in game, it just shuts itself off. Other times when i start it up, it minimizes itself, and WONT let you maximize it again. And you can still hear the game music running when its minimized. Some other things that have happened, when just surfing around the internet, it will LAG like no other. And all thats running is IE, and AIM. Somthin weird is going on for sure. I just upgraded the comp like 2 months ago, and now its gone haywire. Any suggestions???? I hate calling tech support, cause usually i fix the problem myself, but in this case, im stumped
