Bug in sleep mode - user locked

I bought a new notebook running windows 7 64 bit a couple of months ago

After running a full system scan with Kaspersky anti-virus a couple of days ago I now have a bug with sleep mode
- After going into sleep mode, the user with my picture icon is locked meaning that I can't enter my password to log back in - the password box doesn't show.
- With the ASUS face recognition scanner I'm logged back in, but everything is 'buggy' e.g. if I click on the start button and hover over that entire area it goes into sleep again, or if i click on the bookmarks on chrome it doesn't show them, instead it click on an actual site within the bookmarks.
- After going into sleep the only way to enter and return to a normal state is to click the 'switch user' whereupon, my user picture icon reverts with the password box

I have tried a system restore but this didn't work. Any help appreciated

Windows 7 Home, 64 Bit

Kaspersky anti-virus

Check for Windows corruption:

• Check Windows for corruption. Run SFC /SCANNOW Command - System File Checker up to three times to fix all errors with a restart in between each. Post back if it continues to show errors after a fourth run or if the first run comes back with no integrity violations. Use OPTION THREE of SFC /SCANNOW Command - System File Checker to provide us with the sfcdetails.txt file if errors occur.

Check for viruses/malware:

• Download and install Malwarebytes, update it, do not start the free trial, and then run a full scan. Also run a full scan with your antivirus software installed on your system. If you do not have antivirus software installed, see the Good and Free system security combination. for better security steps and scanning tools. Make sure to update the security software before running the full scan.
