games freeze my whole comp

i have recently been trying to play zelda-ocarina of time, but it keeps crashing after i play for about 5-10 mins. it actually happens with most of the roms i have. when it happens everything just stops. my mouse will work for about 10 seconds, then everything freezes and i have to cut the power and turn it back on. the latest time it happened, i got the "windows has recovered from a serious error" message, along with these two files that it said had crashed. do these have anything to do with project 64?

like i said before, i dont think my video card is the problem. i can play almost any game out there on 800x600,even half life 2 if i turn down some of the details. so i dont think thats the problem.

as for other apps running, i usually only have firefox running, but ive also tried it without anything running. and with nothing else running, p64 never uses more than 50% cpu. i do have the windows security center running along with avg virus protection, ill try it with those disabled.

the only other thing is, i am using an xbox controller with an xbox-usb adapter i bought. i use this with many other programs and dont have a problem. i tried switching controller plugins but that didnt work. ive tried without it, but i cant play for more than a few mins with the keyboard cause i hate not having an analog stick to use.

well i think i figured it out. it seems since i was using a controller, my screen saver was kicking in every 5 mins. i disabled that and it seems to be working now
