XP machine really Slow.

My computer is a Compaq 5322RSH P4 1.7 Ghz, 512mb ram, 60 Gig HD, with a MSI LD128LF graphics card.
On C drive I have 8.73GB used and 43.2 GB Free.
on System_Sav D: I have 2.56GB used and 1.33GB free
I have always had XP on this machine since it was new.
When the computer starts it takes forever to load the programs. Maybe, about five minutes. Norton will start enabled then sometime during start up will go disabled. Sometimes it starts ok and other times it starts disabled. After XP loads up and is ready to go. It still runs slow. I will click on a program and wait a minute or so for it to start.
I have 900Mhz ME machine with 192MB of Ram that seems to run faster than this machine.
All of my scans are coming up clean. Ran Spybot, Adware, Norton, Ewido, CWShredder, CleanUp, TrendMicro Scan and the online Panda Active scans.
The security section found nothing wrong with my machine and referred me to this forum.
i don't know if you can use the HJT log but, here it is. It will give you a idea of what my machine is running.
Here is the link to the Security forum so you can see what was done.
