I'm running Windows XP Pro SP3 on a Dell Latitude D620, with an Intel Core2 Duo processor. About a year ago, I upgraded from the 1GB (512MB * 2) that came with my laptop to 4GB of memory (2GB * 2). I didn't notice much of a difference, but I didn't think about it for a while. This week, I've been doing some spring (winter) cleanup. I checked my BIOS settings and noticed that they report only 2048MB of memory installed. I had already been planning on opening up my laptop to see if I could blow some dust out, so I tried reseating the 2GB memory chip accessible under the keyboard to see if it would make a difference. However, my system is still only detecting 2048MB of memory, and I am now having memory issues such as lag and programs hanging, even with only a couple of tabs open and very few background processes. I checked Task Manager and when programs hang it shows 100% CPU usage. I'm pretty sure this isn't a software issue. Do you have any suggestions?
For what it's worth, System Information (msinfo32) reports the following information:
Total Physical Memory 2,048.00 MB
Available Physical Memory 1.43 GB
Total Virtual Memory 2.00 GB
Available Virtual Memory 1.96 GB
Thanks in advance,
