Windows 7 should not have any problems with this amount of memory (4GB). This means the problem is somewhere else. You can start from a beginning and just take a different direction.
You are on a page that is part of Computer Troubleshooting Guide. If you have arrived here not from the start I suggest you click here and start from the beginning. The software will ask you some questions and it will try to solve your computer problem.
If you arrived here from the start please continue as normal.
