Yesterday I accidentally downloaded some malware and used malwarebytes to fix the problem. I normally don't have any problems but this time after running the program fixing all that it finds and rebooting, my computer won't start. It's a fairly new del so I can't imagine it being a hardware issue.

On the back of my tower near the plug there's a green light indicating power but the on button is just not responsive..

Hi, :welcome:

We will need to view the system status from an external environment. You will need a USB drive and a CD to burn. There will be several steps to follow.

Download GETxPUD.exe to the desktop of your clean computer
  • Run GETxPUD.exe
  • A new folder will appear on the desktop.
  • Open the GETxPUD folder and click on the get&burn.bat
  • The program will download xpud_0.9.2.iso, and upon finished will open BurnCDCC ready to burn the image.
  • Click on Start and follow the prompts to burn the image to a CD.
  • Next download driver.sh to your USB drive
  • Also Download Query.exe to the USB drive. In your working computer, navigate to the USB drive and click on the Query.exe. A folder and a file, query.sh, will be extracted.
  • Remove the USB & CD and insert them in the sick computer
  • Boot the Sick computer with the CD you just burned
  • The computer must be set to boot from the CD
  • In some computers you need to tap F12 and choose to boot from the CD, in others is the Esc key. Please consult your computer's documentation.
  • Follow the prompts
  • A Welcome to xPUD screen will appear
  • Press File
  • Expand mnt
  • sda1,2...usually corresponds to your HDD
  • sdb1 is likely your USB
  • Click on the folder that represents your USB drive (sdb1 ?)
  • Confirm that you see driver.sh that you downloaded there
  • Press Tool at the top
  • Choose Open Terminal
  • Type bash driver.sh
  • Press Enter
  • After it has finished a report will be located on your USB drive named report.txt
  • Then type bash driver.sh -af
  • Press Enter
  • You will be prompted to input a filename.
  • Type the following:

    Winlogon.exe

  • Press Enter
  • If successful, the script will search for this file.
  • After it has completed the search enter the next file to be searched
  • Type the following:

    explorer.exe

  • Press Enter
  • After it has completed the search enter the next file to be searched
  • Type the following:

    Userinit.exe

  • Press Enter
  • After the search is completed type Exit and press Enter.
  • After it has finished a report will be located in the USB drive as filefind.txt
  • While still in the Open Terminal, type bash query.sh
  • Press Enter
  • After it has finished a report will be located in the USB drive as RegReport.txt
  • Then type dd if=/dev/sda of=mbr.bin bs=512 count=1


    Leave a space among the following Statements:

    dd is the executable application used to create the backup
    if=/dev/sda is the device the backup is created from - the hard drive when only one HDD exists
    of=mbr.bin is the backup file to create - note the lack of a path - it will be created in the directory currently open in the Terminal
    bs=512 is the number of bytes in the backup
    count=1 says to backup just 1 sector


    It is extremely important that the if and of statements are correctly entered.

  • Press Enter
  • After it has finished a report will be located in the USB drive as mbr.bin
  • Plug the USB back into the clean computer, zip the mbr.bin, and except for the mbr.bin zipped file, post the contents of the report.txt, filefind.txt and RegReport.txt in your next reply. The mbr.bin zipped file must be attached to your reply.

The button must turn ON the computer, else, you are experiencing a hardware issue. If a laptop, remove the battery and attempt to boot the computer just plugged to the wall without the battery. See if able to boot.

It's a desktop. Is it possible the virus toasted the motherboard?

That is nearly impossible. What about the Power Supply Unit (PSU). Have you experienced any issues with it in the past? Does at least tries to fire up?

Remove all peripherals, whether external or internal (Printers, Scanners, Internal Modems, PCI Cards,...etc, leave only the Monitor, Keyboard and Mouse connected) , and attempt to turn ON the computer.

Check if there is any power on the wall or source.

I've never had any problems with the power supply. No it wont fire up. I plug it in and a little light attatched to the power supply lights up, but nothing else. I tried removing all cords, leaving only the pc connected and the button isnt doing anything. I moved the Pc to another wall and it still doesnt work. =(

The problem is definitely hardware. There not much we can do in this regard. Only a technician by means of an onsite diagnostic may be able to identify the problem.
