Thread: system hangs randomly

hello, have toshiba l755-s5244 laptop , installed latest ubuntu. working fine except kept getting reports fro apport saying it's detected problem. naturally googled when asked if had reboot , disabled apport because endless. laptop seem hot (the fan kicks on , runs full blast) until kill apport noticed running 99% cpu when looked in top see program might going wild. so, disabled apport , i'm still noticing these random freezes mouse moves nothing responds @ all. it's brief , lasts maybe 10 seconds , indefinitely locks up. couldn't switch terminal or anything. i've done googling , i've seen posts on forums others experiencing but, seemed lead me nowhere, ones seemed promising dead threads no solution. i've considered graphics might issue, lookd in system setting>system details , found graphics comes driver unknown. ideas fix appriciated. thanks, in advance.

additional notes: did more googling , found laptop apparently 64bit comes installed win7 64bit installed on it. checked command listed on ubuntu site , came 64bit. so, i'll try switching out 64bit version in hopes corrects whether it's goofed install or, incompatibility 32bit , system. doubt that's but, why not take full advantage of system. hate doing reinstalls but, it's no me when freezes frequently.
