- what's your OS (Windows 98, 2000, ME, XP, Vista)?
- if you go into the BIOS-setup at boot, what does it say about the memory?
I reformatted my hard drive, and I noticed that under "my computer" it is only showing 512 megs of memory. I have 1 gig installed and that is what it showed before I reformatted. How do I get my pc to recognise the total amount of memory that I have installed??
