Just double click the Start Up program in the Control Panel, icon looks like a little computer, and it will open.
To check your Virtual Memory settings Right Click on My Computer. Choose Properties. When System Properties opens click on the Advanced Tab. When that opens then click on the Advanced Tab there. When that opens click on the bottom button, Change. When that opens note what is there and post back here with the information. You should see something like this; Paging file size at the top and it will show you something like 1536-3072;
In the middle you will see boxes with 2 different numbers, give me those and then at the bottom you will see 3 listings; Minimum Allowed, Recommended and Currently Allocated.
Give me all those numbers.
