I've got a Mac Pro (Intel) which has worked flawlessly for 3 years. However, a week or so ago, on boot up, I got a solid blue screen, and nothing more. The mouse pointer is there - and although it responded initially, now no longer does. I can hear the HD clicking - but it never gets beyond the blue screen. Have rebooted too many times to remember ... and nothing. Any thoughts? Running 10.5.
This symptom can signify one of the following things.
1) Mac OS is corrupted and needs to be re-installed."Archive & Install"
2) You hard drive is rendered unbootable, Erase & Install may work.
3) Hard drive needs replacement

It's hard to say without more information. When you say it doesn't boot, does the screen come on at all? (the first thing that shows during a boot attempt is a gray screen). If the screen does come on, what does it show? Also what year is the macbook pro?
1. Restart the computer. If necessary, use the reset/interrupt button.
2. Immediately after the system startup tone, press and hold the
Command-Option-O-F key combination. The computer starts up to a
text-only screen, indicating that you are in Open Firmware.
3. At the prompt, type: eject cd
4. Press Return.
5. Type: mac-boot
6. Press Return
The fact that the "BONG" sound (or better known as the MAC CHIME) does come on and nothing further means that the computer cannot find your hard drive or (sometimes worse) cannot find the operating system. This means that you will have to remove the hard drive... then insert it nice and firmly again. Try now to boot. If nothing happens then your drive has gone faulty and it could mean that you may have lost your data... NOT NECESSARILY though.... What I mean by that is that you may still be able to access the dat when you connect the "faulty" drive to another computer via USB with an external casing and then get your DATA off it.
Parallels won't have caused this, Bootxchanger might have but it's not likely.
More likely is that you HD is faulty.
A largish number of white Macbooks shipped with faulty Seagate HD which, although fine to start with, started failing after about 1 year of use.
I've seen 3 in the last six months.
Thankfully the HDs in these MacBooks can be changed in just a couple of minutes, the bad news is that the data on the drive is generallycompletely destroyed.
Try starting up from your install DVD, but not do the install. After you get asked about language, at the next screen, go up to the menu bar and locate disk first aid. Run that - you may be lucky and it fixes it or you may not.
I had the same problem with an Intellistation 6868 for years. It just wouldn't load XP but ran fine on Windows 2000 SP4. I tried 3 different XP Installation CD's with no luck. After several attempts at installing XP I bought a clean XP Upgrade from ebay.
It took me 3 goes to install it but eventually I got it in there. If you can get XP to start on the 6868 press F8 and start it in safe mode first then when it's booted fully, shut it down and and then start it clean again. It worked for me. I've been running it for 5 months now and it's fine.
I couldn't get it to work at all on the 6868's onboard IDE so I installed a PCI Raid Card and it boots fine on that.

You should only use Windows xp for running a program that is
not yet available from Apple. There shouldn't be much reason to link to
the net while in Windows. Also while in Windows you are wide open to any
viruses that exist. Try getting your work done without getting on the
net, then go back to your Apple format. There you are 99% free of
viruses. … Still need to link onto the net let me know I will ask at our
Apple Computer Club on Monday
