I dont suppose you can push the shaft back into position can you? I havent opened one up in a long time, dont quite remember the bushing and shaft, so you would certainly know better.
On the Compaq, I dont know what age your puter is, but if its done the way i have seen they use what is called rompaq's. They are simply bios updates. All you do is go to their (HP-Compaq) tech support, then find your mobo, then find your rompaq and download it. I believe the instructions go with each rompaq, but if not, you can also print out or download the instructions, which, actually are pretty simple and standard. The only difference is that the rompaqs place the bios on part of the hard drive instead of a rom-bios chip on the mobo. I think thats the way it goes.
But all you have to do is do as it says and all will go well, just make sure you get the correct rompaq. ON the other hand, if you get the wrong one, i dont think it will even install, they have it done pat.
But if you need help along the way, let us know.
Usually its a matter of putting the new bios on a win98 boot disk, insert the disk into your floppy drive, turning computer on, going into bios and setting your bios so that it boots from the a drive and reboot. Then when you get to the a drive you type in the name of the new bios and it does all the work. But check the instructions they give you, should be about the same as this.
After that you may or may not have to re-set your bios by moving the jumper from 1 and 2 to 2 and 3, remove battery and remove all sources of power, like the power cord to the wall outlet. Wait a while then put the jumper back from 2 and 2 to 1 and 2 and put battery back in and power up.
Buy you may not have to do that.
One thing, before you start, boot up and press the "pause-break" button as it boots and write down the bios info string, should be at the bottom of your screen but may be on top, anyway write down the info so that when you install the new bios you can see that its different and should have newer date on it as well!
Good luck, they usually go well.
