Windows 7: Cannot Boot system at all and getting Black screen

Cannot Boot system at all and getting Black screen


I am new to this forum and I just recently encountered an issue with my laptop.

Last night I got the windows 7 antivirus pro malware which i tried to remove by downloading avg antivirus. It deleted some files from the registry i believe and I had to do some other things to make .exe files work again.

After that everything was running smoothly until again later at night i got one of those viruses that locks your computer and turns your webcam on saying that you are being monitored by the government and need to pay 100 dollars and all that.

I immediately knew it was some malware and forced shut my laptop off. I logged back in and it happened again.

So after that i rebooted the system and did a disk repair. I left my laptop on all night and in the morning it was at the exact same spot i left it at and wasn't responding. I then again forced shut off the computer which was a mistake because now i can't boot it completely at all.

If i try to boot it in safe mode with networking it freezes at the directory avgidsha.sys . Then i get the black screen error where there is just a black screen and my cursor.

If i boot it with last known settings i get the black screen after the windows logo.

if i go to repair system it doesn't let me do anything. When i try to do the actual repair it says that make sure there is no camera or device attached.

i cant restore the system and i tried a whole bunch of things in command prompt like sfc/scannow but it says that you need to reboot your system for the disk repair to be completed.

Also i got the laptop from bestbuy with windows 7 already installed and dont have the disc

Can anyone help me? I've never had this issue before and its happening during exams when i need the laptop the most. Any help or guidance would be appreciated. Thank you
