[QUOTE="James Snover, post: 16312792, member: 67454"] I had an old ultrasound machine by a company I can't name, but it was good enough, if you know what I mean. It would lock up on boot-up, right after BIOS. Just sit there, for. freaking. ever. And do nothing. It was early days in the medical biz, for me, and I was a bit stumped. So while I'm trying to figure it out, I see the CD-rom light is on, constantly. I press the button to open the cd-rom and see what's in there, and the instant I do ... it boots up! Huh. Well ain't that something? I'm finishing up, and I decide to do a full shut down and reboot. Locks up after BIOS. CD-ROM light on solid. press the button, tray opens, machine boots up normally, works perfectly. Ok. On a hunch, I grab the vacuum cleaner, and vacuum out the open cd-rom tray. Man, 15 cubic feet of dust and lint must have come out of that slot! After that, it works perfectly, boots correctly. Turns out that there was enough dust and lint to make it think there was a CD in the tray, and boot priority was hard-coded that it always looked to boot from the CD-ROM first, then the hard drive. So if it thought it saw a CD, as it did when it was clogged with dust and lint, it would just sit there forever, endlessly waiting to see the OS on the CD! After that, over the next ten years, I fixed a ton of of those systems for the same problem, armed with nothing but a vacuum cleaner. [/QUOTE]
