Had the same thing only it stuck at 83% kept telling me my install disc was corrupt, took out one of my memory modules that i'd recently put in to upgrade and it worked perfectly. it might be the place to start as ashdav has had the same problem...
I use to get the blue screen of death. And on its own it use to reset every now and again. I swapped HDD's and the problems went away. But i suppose you can tell the health of the HDD with the noise it generates.
If one of the RAM sticks (or a certain part of it if there's only one) is playing up then it will not show up until that particular volume of RAM is reached during the installation. Repeated attempts at reinstall will result in failure at the same stage. It can be misleading as the HDD maybe faulty as has been mentioned and this will give the same result. As it's easier to replace RAM this should be the first thing to address. A good indication of where the fault lies is that faulty RAM will cause the computer to freeze during intensive applications (video is a good example) whereas HDD failure usually causes the computer to fail to boot and is accompanied by mechanical noise. This is only a rough guide and the best tool is to test by substitution.
To test your RAM (one stick at a time is best)click here You need to copy this to a floppy and boot from it at start up. Hope you've got a floppy drive. If there's a fault it will usually show up within 30mins but the program will run forever unless you stop it. For the paranoid amongst you it's usually enought to let it run overnight. If you get any red (bad) results then the RAM is goosed. Blue is good.
