You do have some problem. I do hope that you have more than 140MB of RAM in your PC. Heres how to change the size of your swap file if youre running XP:
Go to Control Panel > System > Advance > Performance > Settings > Advance > Virtual memory and choose "Custom Size". Make the Initial size 1.5 the amount of RAM you have on your system (or at least the same size as your RAM). Make the max size twice the initial size (3 times the amount of Ram). For 256MB of RAM, the initial size should be 384MB and the maximum size should be 768MB. Select Set to apply the new settings. Click OK and reboot your PC. Your problem should be fixed.
