My computer has developed a strange set of 'symptoms'. The first thing I noticed, was I tried to run Scan Disk (as routine maintenance, it had been fine) and after rebooting it said it was running and instantly said 'disk check was canceled'. It now does this every time I try. I don't have a stuck key; the keyboard seems fine, and dell diagnostics found no keyboard or hard drive issues. In MS One Note, the highlighter pen won't work. When I click, my pointer turns into a pen for a split second, then back to a pointer. At Windows live mail, the options menus will not stay open. I have a systray utility for keeping windows on top. When it is clicked the pointer turns into a push-pen until you click the title bar of the window you want to keep on top. Now the pointer just turns into a push-pin for a split second, then disappears. The windows screen- saver preview also quit working, and in another program with small pop-up type help windows, those won't stay open. It has also gotten slower responding when I type. Sometimes, it will not register 3 or 4 characters, then they show up at once. The other thing I have noticed is in My Computer, wen I right click on C: and click properties, it occasionally brings up Control Panel-System instead. This may not be related, because everything else I have listed is consistent, every time. Another possibly related problem is a third-pary program that has started giving "overflow" errors. This program isn't the cause, I have used it since the computer was new, and I'm not sure it's related because it seemed to start more recently than the other symptoms. I haven't installed any programs, or made any system changes that should cause this. I'm using Zone-alarm Anti-virus/Antispyware and firewall, as well as WIndows Defender. They have not detected any problems, and a full scan of both ZA and Defender showed nothing.
This has me stumped, any help is appreciated.
