anthlon-xp 3000 in older emachine-UPGRADE?

[JustME]

I have an older emachine (T3065)...it has an AMD Anthlon-xp 3000 processor in it. I run windows XP.
Last December while trying to put together a family slide show made up of old photos's etc, with a newly purchased Corel Video studio/paint pro combo...I discovered my processor wasn't large enough or speedy enough to handle the whole dvd authoring thing. (I wanted relatives to be able to view said slide show on their TV/DVD)
No matter what I did, the program would close unexpectedly. I am not computer savvy. My fault.
My hard disk drive just went "boom" and I will need to replace it...perhaps my monkeying around with hundreds of photos and a non functioning program finally did it in...at any rate....IF I am going to have to replace the hard drive? Is it possible to also upgrade the processor?? Would I also need to install/replace the motherboard?
Believe it or not? This has been a great computer...but I have definitely "outgrown" it. A friend told me a "rebuild" would be more expensive than buying a whole new tower...hoping he is mistaken. Could anyone help? make suggestions? Thanks for your time. [/i][/b]

Check system requirements for your DVD authoring program. If it requires SSE2-enabled processor then fixing your old system won't make any sense, as you won't be able to use the software after your system is up and running again.
