After getting annoying notifications from avg saying i had a trojan on the file rpcss.dll i replaced the file and now that i restarted my computer i just get a black screen with my mouse at first i thought it was my motherboard but i just got a new one today and its not it. So it has to be the os but i dont know how to fix this at all i cant get past that black screen with the mouse, that i can move, its just getting annoying because i had to wait 2 weeks for the motherboard to come and now that wasnt the problem is getting me kinda of pissed off
