It happens a few times that while I am on the explorer cursor simple disappear and everything frizzes, so I have reboot the comp manually.
Thatís first, and second: twice I did that it reboot itself but with completely black screen (as it didnít start itself). Both time I have unplug comp and screen from the electricity and everything was fine.
There is no any mistake on event log.
For the info: I have all utilities as you advised in malware forum, and run (and update) them regulary and I donít have any problems in that department.
What can cause these frizzing.
Thank you for any advice and help.
