Need to upgrade my computer, is it even possible?

[timcrow420]

I recently got my computer back after not having it for about five years. Got the internet turned on to it and it barely runs.

I used to operate pro tools Express with the mbox 3 interface. But I lost the installation driver disc and the pro tools Express software disc. so if I was to replace my computer I'm sure I would need that, and I cannot find them on the internet anywhere.

would it be wiser just to try to upgrade my current 32-bit operating system? It only has 2 gigs of RAM, and runs on Windows 7 which will only work with Express.

I don't know what to do, and I don't know much about the I lock device at all it's been so long since I hook this thing up I've never been in this situation before of transferring and reinstalling programs I don't have the disc too. This sucks
