My main question is Would too low of ram make processor max out and make machine super slow ? Windows vista upgraded from Xp - 768 mb ram and intel celeron d 330 is what is in machine - or could it be virus ive ran both virus and spyware both came back clean - O also 160 gb HD

Both the RAM and CPU are an issue, unless you have a clean Windows setup with clean drivers, the Celeron D is pretty slow. You want 2 gig of RAM as a minimum for decent performance, and 4 gig would be ideal.

768mb is absolutely too little ram.
It will cause a large number of hard page faults and activity on your hard drive.
It will look like a cpu bottleneck because the cpu must pause while the page fault is resolved from the hard drive.
I had a 1gb laptop with abysmal performance. 5 hours to do some windows updates.
I added 2gb and it was magic.

I also converted to a ssd and the end result was a very satisfactory laptop.

The laptop I fixed up was a 7 year old lenovo R61 with a slow cpu.
After the ssd and ram, it worked very well.
I have converted to ssd on every one of the family laptops with very satisfying results.

2gb of ram and a 120gb ssd will cost you a bit more than $100.

ddr1 or ddr2 is a motherboard issue, not a xp issue.
Since your motherboard may not tolerate a mixed kit of ram, pay attention to compatibility.

You want documented ram compatibility. If you should ever have a problem, you want supported ram.
Otherwise, you risk a finger pointing battle between the ram and motherboard support sites, claiming "not my problem".
One place to check is your motherboards web site.
Look for the ram QVL list. It lists all of the ram kits that have been tested with that particular motherboard.
Sometimes the QVL list is not updated after the motherboard is released.
For more current info, go to a ram vendor's web site and access their ram selection configurator.
Enter your motherboard, and you will get a list of compatible ram kits.
While today's motherboards are more tolerant of different ram, it makes sense to buy ram that is known to work and is supported.
