Turn off the computer, then hit the power button to turn it back on and immediately start hitting the F8 key repeatedly until you see SAFE MODE. Take the Safe Mode option and let it boot up. Safe Mode will look different to you, the screen will be darker and the icons bigger, this is normal. If the ? key works in safe mode then there might be a virus or infection that has it. Take the steps above to get into safe mode, but this time select the Safe Mode With Networking option (this will give you internet connectivity). When it boots up open up your internet browser and download and install MalwareBytes. Go to www.google.com and in the search box type: "Download cnet Malwarebytes" (without the quotes). Download and install malwarebytes from the sites download.cnet/malwarebytes. When the site opens up click on the Green Download button on the left. Do not click the Red Download button, that's junk. When it finishes installing the Gui Interface will open up with an offer to Accept a Trial Version or Decline. CLICK DECLINE you want the totally free version. Run a QUICK SCAN. As it scans, if it finds infections the number will be in red. When it finishes scanning, click SHOW RESULTS. A notepad text document will open up showing you the results. You can close the text document and go back to the Gui Interface where you will click REMOVE SELECTED RESULTS. The objects will already be selected for you. When it finishes removing the objects click ok and it will sometimes reboot your machine. If the ? key still does not work your keyboard might be bad for that one key..Here is a work around. Download and install the Virtual Keyboard. Anytime you need the ? key just point and click on the virtual keyboard with your mouse pointer and it will appear.
Go to www.google.com and in the search box type: "download.cnet.com" (without the quotes). Click the link to go to the site and look on the left side when the site opens up and you will see a gray area that says FIND SOFTWARE. In the white search box under Find Software type: "Virtual Keyboard" (without the quotes) and click the mirror to search. When the search results come back look for FREE VIRTUAL KEYBOARD. Download and Install it. It's totally FREE. Also uncheck anything that pops up other than the license agreement during the download and installation. You only want the Free Keyboard and not the other junk. You can use it to solve your keyboard problem. Just open up whatever it is you want to type on such as the web address in an browser, a word document, etc., then open the Free Virtual Keyboard and it will sit on top of whatever you were doing. You can move it around so that it is not in your way also.
