Second map load crashes

well… the title really gives it away… not alot to say…
Gmod runs fine… no errors or anything… but the second time a map loads… right before getting in… it crashes…
like… load a map and play… its fine… load another map and at the end of loading… CRASH

ive deleted EVERYThing… wiped it all out… and reinstalled Gmod… twice… and im still getting the problem… help?

System hardware specs
Processor - Intel Pentium D CPU 3.00GHz, 2.99GHz
RAM - 2gbs
Graphics Card - ati radeon x300
Operating System - windows XP media center 2003

Addons - Ive ran Gmod without ANY addons… right after i wiped it clean… and it still crashed :expressionless:

Ok well… i reinstalled windows :"|
and now everything’s fine…

never /did/ find out what the problem was… but whatever… its gone now…

You reinstalled windows because of a problem with ONE game?

Wow,that wasnt the best idea ever.
