Cursor goes crazy, then computer slows down and freezes
Hi,
Since my screen turns black (instead of blue), I don't know if this is the correct forum to post in. The problem:
The mouse cursor (normally a black outlined white arrow) will, with no warning, turn weird-looking - and looks fuzzy or blurry, larger than normal, with different colors, it can go from pointy to round, sometimes disappears for awhile. After that, I have only a couple of minutes to shut down open programs before the computer slows down and freezes to the point where I can't click anything.
Sometimes, I'll have left the computer running, go off to do an errand, and come back to see the two monitors have turned black. Ctrl Alt Del does nothing. The only way to shut down is to push and hold the start button until the computer goes off.
Other times when the cursor goes crazy, I'm able to click Start and select restart, but the computer will not restart. It will start powering off, then turn black. I have to manually shut it off (push the start button in).
Upon restarting, the computer will start up normally (after selecting the option to start normally) and will run anywhere from a day to several days until the cursor goes crazy again.
I've run memtest 86+ and it reported no errors after 12 passes.
I saw a thread in another forum that suggested changing the power management of the mouse may help with mouse problems, so I have deselected "Allow the computer to turn off this device to save power" under the Device Manager > Mice and other pointing devices. The mouse is a Microsoft USB Wheel Mouse Optical.
I have no idea if the mouse is to blame, or if the computer is having other problems.
NVIDIA GeForce GTX 550 Ti display adapter is up-to-date, according to Windows.
In Device Manager for the mouse, the General tab says "This device is working properly"; and when checking for updates, Windows says driver software is up-to-date.
I read posting instructions and got stuck on #1 - configuring dump files. Which dump file should I configure?
I went on to #2 and ran SF_Diagnostic_Tool.exe. I couldn't see the SF_25-12-2013 folder on my desktop, but found it here: D:\Users\User\Desktop - Attached is the zip file.
Hoping someone can help detect what is wrong.
Thanks
