Create a new windows user account (make it an admin one) and re-test.
Since it's for business I'm sure you keep backups of all your stuff so a restore from the last full backup will correct software glitches.
I have read countless pages on the "blinking" cursor issue...to which I have found no resolve. Let me state my issues:
I have Win 7 64 bit, 16 gig ram, etc in a high end Intel processor setup.
My problem is that the as soon as Windows comes up the mouse cursor start having the blinking "circle" next to it at a high rate of blinks. Also, when I move my mouse on the screen...it seems sluggish.
Next, when I click on the search window of a my browser (Google Chrome), I see the slash mark (where your first letter should start) but when I start to type...nothing. Then I've come to realize that if I go to click again to start typing...I don't get the "start point" slash mark....its as if the browser window is disengaged. If I re-click on the search window....I'll get the type slash...but by the time I can reach for a key to type...the window disengages and nothing happens...so I have to one finger type..and time my clicks so that I can get a letter into the box.
I have ran task manager, to find processes...and find nothing creating any massive amount of memory or resources being used. Matter of fact....only when it does the scan will Task manager show 1%...then quickly to zero. Every thing else is zero. I have looked for various "files" listed in many other posts on this issue...and find none of them listed. I have ran virus and malware software to no avail.
I have went into mouse control panel...no changes.
I have checked into control settings for everything...nothing.
I have even swapped out the mouse and keyboard..no luck. Both devices are "cabled" units..not bluetooth or wireless. I even tried different USB ports..no luck.
SO....I turn now to this forum for assistance...please HELP!!!! I need to be able to use my computer for business QUICKLY....!!!
