looks low on ram

my computer is slow and freezes for a while on startup. I ran the diagnostics on it.

physical memory 1gb
88% full
available 115mb

virtual memory 2.24gb
available 922mb

I think this is the cause of my problem. Is this correct. if so what ram upgrade do you think necessary?

Hi my friend , welcome to MG's :major

Vista needs at least 2 gb of ram to run properly , go to Start - Run typing msconfig - Ok
go to Startup tab remove ticks except for antivirus - Apply - Ok
Windows asks you to restart your machine - do it
What is your free space in your hdd ? :wave
