SW crashes/freezes when part becomes too complex

Hi there,

I'm running SW2013 on a dell latitude 6530 and I have problems with SW.

When I start creating a part, SW is very snappy, but as the part get more complex it start to hang, and eventually freezes for ever (left it more than 6 hours on a thicken surface with 2mm and merge).

This is the second time this happened. I'm a begginer, so my skill aren't the best, and I'm sure what I designed could of been done faster and more efficienctly, but I stil can't accept this.

i've run SW Rx and I got all 0.0sec so I think my system is decent, but I can't explain why this happens. I have the lastest drivers. I have also dissabled all the power saving features for the laptop. I have set up the graphical card for performace, dissabled Hyperthreading (was a sugestion around here) and also tried the dell ultra power settings with no results. Also I can see SW performing worst when software openGL is enables. I have tried to tweak the perfomances in SW, since I only want to create a part, not to have a fancy rendering of it.

Can anyone help me? Unfortunatly this is an educational instalation so the license is managed by the Uni, and aparently we haven't got the support feature.

I have also attached the systeminfo and performance test (i removed my license number for safety).

I can't attacked the part, but here is a link from my dropbox in case someone want to give it a try and see if it's only me
