hp6715b problem

[mindsifter]

radi se o laptopu hp 6715b gc049es.
ponekad(otprilike jedanput dnevno) laptop se potpuno odjednom blokira, ekran se zacrni i tippkovnica ne reagira.
OS je winxp sp2.

u event vieweru sam nasao ovo(neznam ima li kakve veze):
Error Server
The server could not bind to the transport \Device\NetBT_Tcpip_{59A.....} because another computer on the network has the same name. The server could not start.
