Hello everyone, I am fairly good with computers and have gotten a virus which keeps coming back.

 

My computer was working fine, and then I got a virus which messes up the screen, meaning shows a pattern of my screen warped and shrunk and this pattern covers the screen, then gets a blue screen in dos, and lastly shuts off the computer a few seconds after. This shut-down is similar to for example, pulling the plug, then when I try to turn on the computer, before it gets to windows, it repeatedly shuts down every time. Sometimes when I get to windows it will not stay very long, or at least long enough for me to do a virus scan. I am sure this is a new virus.

 

TO EVERYONE WHO THINKS I HAVE A POWER SUPPLY PROBLEM  BECAUSE ITS SUMMER: I tried taking out my hard drive, removing the cables, then i turned on my computer without a hard drive on, it stayed on for several hours, and then i shut it down by pressing the button.

 

I tried to delete partitions and make new ones, and then format and put windows, but i got the same exact virus. So I was thinking next time I will skip the "connect to the wifi internet, ..... part of setup" and this is where my question comes in.............. Is there a way for me to install and possibly update manually, in offline mode, like if i were to get webroot installer offline so I am prepared and "ready for action" when I turn on the internet?

 

If this post is moved, please kindly send me a private message, as I was not sure where to put it, and if you need more details just ask and I will write more.
