Hello,   I am somewhat ignorant when it comes to anything beyond computer basics.

 

I have a Lenovo H420 Desktop, with Windows 7 home version - 64 bit, 1 Tb HD, 8 GB Ram.

 

Last week I found out from my ISP that my e-mail account had been hacked and was being used to send out spam e-mails.  I ran my AVG security program and it found nothing.  I restarted my computer and now all I get is a blank black screen with an active curser.  The numlock and caplock keys still work, I have left the computer on overnight in case it was a slow start up but that did nothing.

 

I have tried using my recover disks that came with my computer ...they run through the recovery but it changes nothing.  I tried running malwarebytes from the dvd drive...it found nothing. 

 

I have all my important data backed up to an external storage drive so at this point I think I want to re-format the HD and reinstall Windows 7.

 

I have no idea how to do that.  Windows 7 came installed on my computer and I cannot find a product key anywhere on the tower or with the paperwork that came with the computer.

 

What would be my best avenue to format and re-install windows under these circumstances?   Or is there a chance that I could fix the problem with out formatting?

 

I am able to bring up the command prompt in safe mode.

 

Thank you very much to anyone who has the time and expertise to help...it would be greatly appreciated.

Thank you for responding Louis.

 

I mistakenly forgot to include in my first post that I was able to run the Lenovo "oneKey" recovery and reset to factory default settings.  Doing that did not change anything in regards to how the computer acts on start up.

 

 I'm sorry I wasted your time by forgetting to include that in my original post.

 

 

I really appreciate your help Louis.

No problem with the omission, hardly anyone includes all pertinent data without prompting/questions :).

 

Unfortunately, I can't suggest any more than I have.  I'm not very familiar with OEM systems in general and certainly not familiar with Lenovo systems...but others here are.  Relax and wait for one of the more knowledgeable members to respond to your topic.

 

Thanks :).

worth a try

STEPS:
1. Boot up as normal, and wait until you see the cursor on the black screen
2. When you're booted, press Ctrl+Alt+Del
3. In the Processes tab of the Task Manager, find explorer.exe
4. If you find one, right-click it and select End Process
5. Select File ? Run
6. Enter explorer and press Enter - the desktop should show up
7. After it has finished loading, reboot
8. This time, your desktop will show up without the black screen
