You computer has the barest minimum of RAM installed for use with XP so no wonder it is slow. Your computer can take up to 512MB of RAM and that is really the best way to go. You should be able to upgrade for a little more than $100. You will be amazed at the speed, it will be like a new computer and much cheaper than a new one.
It is very easy to install...open the case, remove old RAM and plug in the new.
Go to Crucial determine what RAM to order. The site will scan your computer and then recommend the best for your system, remember maximum of 512MB so this would likely be 2-256MB stick of RAM.
Crucial is generally the best place to check and purchase, at least that is what I have found anyway.
I still recommend using Mike Lin's StartUpControl Panel to control auto starts rather than msconfig.
Another thing you might consider is uninstalling AdAware2007....it is KNOWN to slow down a computer and go back to AdAwareSE. Click the name there for the download site for that edition. I tried the 2007 version and found it slowed my computer so I went back to the old version. DO disable SpyBot TeaTimer...it truly is more trouble than it is worth.
Yes, your logs look clean to me. Check out PROTECT YOURSELF FROM MALWARE: Tools & Tips
for what tools to use to keep the computer clean. The ones PP has listed there are the least invasive and use less of your resources. Definitely add SpyWareBlaster
 Omit Windows Defender. Keep Spybot, disabling TeaTimer, drop SuperAnti-Spyware, may be draining your resources at this point though it is a good program for most.
