My computer has had a trojan for some time and I can't go online whatsoever. I tried dial up, wireless and wired ethernet connection. also, with this problem all these error message would pop up. so I decided to reformat and reinstall a fresh copy of windows. I did it and now the video card doesn't work because the drivers are gone, the modem i'm trying to install won't read no sound network wired connection will not work the only that would work was the modem, however once it was installed, i had to restart the computer and a blue screen would pop up saying I need to update by BIOS...I have no idea what that is. I know I need to install the drivers, but most of them are online now I can't go online because of the missing drivers for the modem... what do I do? can i still keep this computer. I told you I know nothing.....please help... what do I do?
