Keystroke lag and general hesitation even after clean re-install
I have searched the web and not found any solutions to this. My fairly new Win7-64 Dell XPS laptop is now suffering from slow downs/hesitations. Benchmarks, however, seem as good as before. The biggest problem is with typing. Keystrokes are not recorded immediately and can lag many characters behind....up to 20-30 or more if I type really fast, although they all eventually show up. This happens in Firefox, IE9, and Word-2010. Notepad, Wordpad, and Thunderbird are fine. This was so bad I started over and did a clean re-install of Win7 but it is still doing it just a day later. Also, videos are very choppy and missing many frames. Everything seems to have some sort of hesitation.
I have found lots of suggestions on the web and even some on this site; but no solution yet. There must be some clue as to why the problem exists in browsers, but not Notepad. I disabled everything in msconfig but it still does it. I disconnected all LAN/Wireless; still does it. I tried safe mode, and while it appeared a bit better, it was still there. Some have suggested it was the charger/battery; nope. Ran CCleaner; and while it seems to help Firefox for a few minutes, it does not last long.
This is driving me crazy. Does anyone know what this could be?
