i need help with my toshiba qosmio x305-q701 please help

so my laptop was running great and all that and it was running like a dream. then it turned into a nightmare. i dont know waht it is but it started when the cd drive would not open for anything. i tried everything from pushing the button like 4534958345 times, then i tried right clicking and ejecting and that didnt work, i tried everything from force restart to regular restart, and then i finally manually opened it with the manual open on the cd drive. then it was working fine from there. so then like 2 days later, every time i play a game like call of duty to like stronghold 2 it will lag after about 5 minutes and i dont know waht it is. the only games that dont im guessing is warhammer online or world of warcraft because they are straight on my hard drive. i erased a bunch of programs that i have never seen before, etc etc system restore and defragment, disk cleanup all that crap, and it still is not happening at all. now, im guessing that its something to do with the cd drive itself but the thing is i had problems with the cd drive before and i called tech support and there was a file i looked up in the search bar and i had to delete 2 files and when i did that it magically worked again. now im in iraq though so my internet is limited and i cant call 1800 numbers from here wich is so annoying. can someone please help me its ver important.

also when i hit the fn key it used to have a drop down menu from the top. idk what happened but that isnt happening anymore i think that has something to do with it. is there a link where i can talk directly to toshiba or can someone please help me fix this crap
