Keyboard locks a few minutes after turning on

[Woogie]

I have a Dell Inspiron 9400 laptop. 

I can turn it on and get online okay but after 15 to 30 minutes I'm unable to type anything, either as a a web address, on a webpage or even in a word document.  If I'm on Internet explorer the system beeps for every keystroke made but nothing is entered.  If I hit the "f" key the File menu dropsdown, the "a" key the Favourites menu dropsdown, the "h" key the Help menu etc. 

I can continue to navigate online but only using the mouse, not the keyboard.  I've used Firefox and the same issue occurs.

If I reboot this fixes the issue for another 15 to 30 minutes and the cycle continues.

Another issue is that a lot of icons won't open by double clicking.  I have to right click and open.  I've checked the double click speed in my mouse setting and they're fine.

And sometimes when I click on dropdown menus, eg File, Favourites, start the drop down box only appears for a micro second then disappears.

I use the Windows firewall and AVG free anti virus.

Two days ago I ran Dell PC Restore by Symantec.  This reverts the system to it's factories settings.  After running Dell PC Restore I uninstalled McAfee security suite (preinstalled but out of date) and immediately downloaded AVG anti virus.  It hasn't corrected the issue.

Any help please?

Your  system might be infected. download malewarebytes and do a full scan, and see if it finds anything, it will also tell you if certain settings are hijacked.  http://www.malwarebytes.org/

Try an external keyboard to see if it exhibits similiar behavior.

I've downloaded malwarebytes and have performed a full scan on all drives.  the result I've pasted below.

I've had this issue before try these ideas:

1) Try to take it out (Keyboard & mouse) and put it back in.
2) Try another keyboard & mouse on the computer to see if it's a computer related issue, or it's just that your mouse and keyboard are screwed up.
3) If in step #2, the other keyboard & mouse are working, then go buy a new keyboard and mouse for yourself.


I had to do Step #3.

Also, how old is your keyboard and mouse, I had to replace my 6-5-year-old Keyboard and 8-year-old ball mouse.


Good luck.
