Hi Tall,
You installed Panda, I see, but you did not uninstall Mcafee. It's murder on the system to run two AMs. They embed themselves very deeply and command a lot of resources when necessary. And they may be checking up on each other, making for an unmitigated disaster. And so I repeat:
If there is one thing I would do, it would be to uninstall McAfee, then use their uninstall utility to really get it off
The hardware isn't strong, so you are going to take a hit if you install Win7. If you can up the RAM, do that, but most of the older laptop boards maxed out at 2GB.
I'm not sure what you're trying to achieve. If it requires Windows, Win8 probably uses less resources than 7, but with both of them, and especially with 8, the question is whether you can find drivers for your hardware.
Or if you're not dependent on Windows, Linux (I like ubuntu and puppy) will give you a modern system that will deal quite well with older hardware, and they're free.
The problem is: I only ran Panda for a certain scan, and they said Uninstall was simply a click away and simple... So I did the scan, and was unable to uninstall Panda. Then, I used Revo Uninstaller on Panda, thought I had it! Then, I saw some remnants, and used McAfee shredder, and thought I got it! Now, I see I didn't, it appears...
This is a desktop, not laptop, so maybe can add more RAM?
What I am trying to achieve is 2 things:
1.to have this computer salvageable: past Windows XP SP3 , and not crash it or slow it down anymore in the process. It is so amazingly slow, that I can really only have one page open at a time, such as MT and not ..ABC news. If I am unable to get past XP,sp3, it is total junk, not even fit for a backup or the grandkids!
2. to learn on this one, how to set up a computer, what is needed to maintain one, what I like to use...(have never tried things such as Unchecky, or Revo Uninstaller, or changed/alternated between virus/malware programs: have never hardened or maintained a computer. I have only used it- turn it on, go look, answer emails,turn it off! The future does not warrant inability or lack of knowledge and experience like I have been doing! Malware is sneakier, faster, prevalent, unseen, and there is ransomware, and other dangers out there now, that just weren't around 20-30 yrs. ago and I need to learn! I need to know how to harden a computer, do backups, scans, deep scans, and since I am getting ready to have a computer built, learning what is good (processor/hardware/ etc.) and what will be too slow in 6 months! (graphics...?).
Thanks. I will look for a Panda Uninstall, and try that again!
