Gmod keeps crashing!

Hello. My gmod isnt wanting to cooperate. I just got Steam and installed HL2 and Gmod and gmod wont let me play in any other resolution that the minimum and somethings dot load and it crashes sometimes. I think it is my processor. I have 1.25 gigs of RAM and i dont think its my video card. The current processor is a Celeron D. Can anyone help?

Thanks
