So I come back from a three week vacation today and turn on my computer for the first time. I go through all the updates for the drivers and software (Malware Bytes, Avast, Itunes, Nvidia) and then after its all done, I proceed to log on the Internet when suddenly an Avast message pops up saying I have a Rootkit virus and it recommends to delete it, so I did. It then says to run a boot-time scan to complete the cleaning, so I clicked yes and it restsrted the PC. The screen went black for over 20mins, the "working/busy" light was lit, so I figured it was doing something.

After more time went by with nothing but a black screen, I decided to turn off the computer. Now it won't start. I hit the on switch, the computer loads for a bit, but the screen is blank and the monitor isn't responsive at all. It appears the computer isn't responsive either nor are the mouse and keyboard because any button I press doesn't do anything. It's nothing but a black screen and it seems like the computer isn't loading anything of working in the background. I've restarted multiple times, pulled out all the plugs then plugged them back in, nothing. Please help!

Windows 7, never had this happen before.

Edit: I get a beep upon pressing the Print Screen button

Sorry for the delay in responding, there just aren't that many of us that help out in this forum.

Do you still need help with this?

 

Most likely the program deleted a necessary boot component.

As such, the first step would be Startup Repair.

 

In most cases (w/Win7), you can get to it by tapping F8 just as the manufacturer's splash screen goes away (and before the Windows splash screen shows up).

It should lead you to a prompt that says Repair this computer" or something similar.  It'll be followed by the different Safe Mode option.

 

If that doesn't fix things, then I'd suggest backing up your data, and then performing a repair install of Win7:  http://www.maximumpc.com/how-to-repair-a-faulty-windows-installation-without-reformatting/

 

You may want to perform hardware diagnostics before repairing Windows in order to ensure that the system is free of malware and that it doesn't have problems with the HDD or memory:  http://www.carrona.org/initdiag.html

Thanks usasma, I do still have the problem. I took it to a tech yesterday and he moved around the RAM and it worked perfectly, I then got it back home and it didn't work again. Problem is no external hardware is responsive; no signal from the mouse, keyboard or monitor, so I can't press anything on the keyboard, the monitor remains a black screen, it doesn't even go on. All I get is a beep when I hit the print screen button

Have you tried wiggling the RAM?

Be sure to unplug the system from the wall before doing this (and be sure to ground yourself on the metal of the frame also).

 

If it still doesn't work, then try one stick of RAM in each of the slots individually.
When switching RAM, be sure to unplug the system from the wall before doing this (and be sure to ground yourself on the metal of the frame also).

Then , if that doesn't work, try it with the other stick of RAM.
