hello,
a few days ago, my pc was slow, probably a virus, I used nortron rootkit tool, and it worked, came back fast, but now the pc turns on once and once not.
that's how it works. I turn on the PC, it works all right, I turn it off, the next power, hp logo appears and then black screen, and continues so, a power works and the next not.
however, when you turn on it takes 1:30 minutes before we put less than 30 seconds,
I reset the compiuter but it did not, I reinstalled the OS with a clean version of Windows 8.1 downloaded from microsoft (also keeping the data) but totally useless,
I reset and updated the bios, I also changed the CMOS battery, but it did not do anything,
What can I do?
thank you
