okay here is the problem on my xp. The mouse cant right click that good anymore i have to hold down the right click for a bit and then release (its not a hardware problem!) and my startup has changed, my sound effect manager doesnt load at startup, neither does norton and a bunch of other apps. Now here is what i did (i hate nvidia, youll see why). so im thinking ill download the latest drivers for my 8400gs (crappy card i know) and so i do, and its from the official nvidia site for 8400gs. so i install it, everything is ok. so i try physx demo's, it says i need directx 9.0c. So i install it (it was too quick, maybe thats the problem) and it said it was succesful. Now i open the physx stuff again and i try a demo, it closes for no reason, i open it again now it says it needs directx 9.0c again. Wtf????? then i go to gbatemp and i start right clicking opening new tabss and all, then all of a sudden, right click stops working, now i have to push right click down for a while, oh and for some reason "rundll32.exe" was running on the way top, i find out nvidia is using it, so i end task all the nvidia stuff and do msconfig to see if its using rundll32.exe and no it isnt. So i restart, and the biggest problem of all, MANY PROGRAMS DONT STARTUP. My soundeffectmanager doesnt, norton antivirus doesnt, and some other stuff. what the hell? so im like fuck it was nvidia!!!! so i roll back previous drivers (cuz the new one was messed up, and i think the rundll32 problem or something???) ok all good. i restart, same thing happens. WTH!!!! (srry i am a pir8 just got me acid 7 by team NoPe) so i scan the crack for acid pro 7, no viruses. is this a virus i have or the startup changed by me excidentally doing something, in msconfig it says most of my programs have stopped and there are only 6 things on the start up tab on the list, wtf???? is this a virus or something??? im currently performing full system scan and it cant anything yet!!! gosh, what the hell just happened. Its either nvidia, me doing something stupid, or directx installation. oh man im f-----!!!! HELP!
