sorry i misspoke i wasnt saying the idea was crazy, i meant this problem is crazy and random.. but it happens weather the rom is playing or not..okay heres the full issue.. i downloaded desmume and then no$gba after desmume was acting up.. no$ plays both nds and gba games.. i was getting no sound for only nds games.. but for GBA games i got sound, and no$ wouldnt even try to play certain NDS games.. i went into sound and it said right away that some settings were causing problems and it fixed itself... so now NO$GBA still wont play most NDS games ( pkmn black2, heart gold, it says reinsert game cartridge) but will play pkmn platinum for nds and gba games... but it has the same problem that DESMUME does, when playing pkmn platinum... and that problem is (on both emulators) that when the emulators are playing NDS games, they will either flash "not responding" really fast and looks like its trying to re-open itself down at the bottom near the start menu.... or it will do that same thing but it will freeze and be unplayable and keep flashing and trying to open itself, then after 30 seconds to a minute it stars again and repeats the process at random.. i am not asking for help with NO$GBA, Desmume is my go to, i only downloaded it because desmume wasnt working, and found out it has the same issue so i know its with the computer.. this makes it impossible to play or record on.. and i want to say thank you so much for trying to help your the only one, ive only found this issue on here and one other desmume thread.. sorry this is so long, i am going to try your advice and disable windows defender right now and see.. just wanted to give u all the info.. and this is a built pc, it was brand new last week with windows 7, i had my computer guy upgrade it to windows 10 enterprise a couple days ago.. so its all new..
it has amd fx-4170 cpu
12gb ddr3 dual channel ram
amd radeon hd 7800 series gpu
ASUS M5A99x EVO 2.0 MOBO

i broke myself to get this pc mainly for emulators, games and youtube, it sucks that its having these issues. thanks again for the help, really.

Please please please if either of you figured out a way to fix this let me know.. I have searched everywhere and this is only the second instance I've seen of this happening besides my own and I cannot get an answer.. 2 suggestions, get an old driver and now Defrag.. if you solved it please post this is driving me insane for 2 days now.
