Need help - pc loggs of automaticly
 

Hi , when i am converting vids my pc automaticly logs off in xp .
When pushing the big button on the case i can click to logon again and then every program is still running .
But when it is logged off my vids offcourse dont convert further ...
Any one has ever had this problem ?

Look at Display Properties --> Screen Saver and make sure you don't have 'On resume, display Welcome screen' checked.

Just a guess.

ok - what are your system specs? how much ram?

Could be overheating.
