Hey guys. My parents have Windows 2000 running on a 700-someodd MHz AMD Athelon, and it takes nearly 20 minutes from pressing "power" to the point where you can actually do anything. I think I could upgrade it for them, but I have a few concerns. First of all, I've been lead to believe that all I'd have to do would be to get a new motherboard and CPU and move all the other components to the new mobo, but I have a hard time believing it's that simple. I speculate I'd also have to get a new PSU, at the very least, and that several other old components would be incompatible with the new mobo. Secondly, I don't know what effect the upgrade might have on the OS (Windows 2000). If I had to reinstall it I'd have to do some research, but it can't be that hard, right? I don't have much (okay, any) experience with building or upgrading computers, so I'd love some help with this. The closest I've ever come was when their computer was running really hot and I had to take out the PSU and the heatsink to dust it out. I have a pretty good idea of what everything is and what it does when I look at the inside of a computer, and I'm pretty confident I could do this without destroying something. Nevertheless, I could use any advice or tips you have. This would be my first job, so to speak (if they'll let me do it). And if I screw it up, I have a (much better) computer of my own they could use .
