|"Packard bell MIT-COU-A"|
Close, but no cigar. It appears it's from Packard Bell EasyNote B3 series? Restart your system & tap the F11 key. There should be a recovery option unless you wiped it out when you installed Win7.
If you did wipe out the recovery partition, you'll have to come up with an XP CD, drivers disc, program discs, etc.
