Solved Windows 7 Login Screen button stops working

[Tristar]

I am having an intermittent problem logging into Windows 7 and it seems to be getting worse, so I was hoping someone might be able to help me.
What happens is: After turning on my Computer and selecting my profile. I type my password, then hit Enter on my keyboard to log in. Nothing happens. And if I try to click on the log-in arrow nothing happens either. To fix this I can sometimes click the Switch User button, which will quickly switch to a black screen and then back to the profile chooser(then it sometimes works to log-in), but other times it just displays the log-in background, then I have to restart my computer to try again.

Any help would be much appreciated.

Thank You,
Tristar

Hello Tristar and welcome to Seven Forums.

Depending on how long you've been experiencing this problem, you might be able to use a restore point to return your computer to a date/time prior to when the problem first began.

If you have difficulties logging in you might have better success by accessing Safe Mode through Advanced Boot Options.

Malware could also cause the problems you're experiencing. If you haven't already done so, do a full scan with your installed anti-malware suite. Since no anti-malware program is 100% effective 100% of the time (if there was such a thing we'd all be using it), I also recommend running full scans with these free products:

Malwarebytes

ESET Online Scanner

Windows Defender Offline (This requires you to make a bootable CD/DVD/Flash drive because it will bypass the usual startup procedure. Best to create the bootable media on a machine that is known to be malware free.)

It's also possible that you might have damaged or corrupt system files. Try running a system file checker scan from an elevated command prompt (option two.) If problems are found, run th escan 3 times and reboot your computer after each scan.

Please post back if anything helped or not.

Thank you for the help. I downloaded Malwarebytes, and ran it and it found some malware that my normal program didn't remove because it was a program i allowed because it used to be legitimate.

Thank you,
