On mouse moven the mouse pointer gets stuck randomly

Ok, first this is a Samsung ssd?
Do you have AHCI enabled in the bios?

Also go to Control Panel>System>Advanced System Settings>Performance Settings>Advanced tab>Virtual Memory. Click Change:



Then uncheck whatever setting is chosen for paging file,
check No Paging File on 2 IBM drive, then Set, OK and reboot.


After reboot return to the same place to highlight the Samsung drive (only) and select System Managed Size, click Set, then OK.

This was already done a while ago.
No paging files into the two old IBM disks.
I have also disabled power saving on USB ports

The issue remains, I have noticed that when this is happenning kernel time are 50% (red curve on task manager, but does not last, say 5 sec)

Hmm, have you ran any virus or malware scan latley, can you check with MalwareBytes?
Try doing a full scan, and if anything shows up just post back.

Also have you tried running a sfc scannow?

sfc scannow : no integrity issues
malware bytes : a riskware was found in the temporary folder... hum let's see

when I use teamviewer on this PC, no problem either with the mouse (this is indeed the remote mouse that is used)...
Very strange

Did the mouse always behave this way? Did it recently start?

Have you tried to restore to a previous backup?

The issue was present under VISTA ... and then I decide to upgrade to Win 7 hopping it will dissapear ... and it did not.
This issue is more disturbing these last weeks.

1. may be I should install a logitech mouse and overide the window generic driver by the logitech one ?

2. I also have a dual boot to XP, I could check what is happening there ?

Did you upgrade over Vista, or clean install. If it was an upgrade the problem may have carried its way through the upgrade.
Does it also occur under XP?

Go ahead and try the logitech drivers and see what happens.
