BleepingComputer.com: Cant format pc

My boot logo screen now takes about a full minute to pass, it previously only took about seconds, and when i try to boot from cd it comes up saying:

boot from cd: _

then it stays on that, even when i press any buttons it doesnt do anything.
and i have tried it with xp disk and vista disk, get the same problem so its not the disks.
also i have tried to do an update while the computer is started up but when its copied all the files and has restarted it has a problem updating aswell with both installs.
my computer used to boot cd's without a problem but it is since it is taking about 1 minute to pass the boot logo this problem has started and i dont know why.

one addition i have noticed aswell is that the ide channels on the start up have changed, they are as follows:

ide channel master 0 EMPTY
ide channel slave 0 EMPTY

ide channel master 2 EMPTY
ide channel master 3 EMPTY

ide channel master 4 DVD DRIVE
ide channel master 5 HDD DRIVE

im sure they used to both be on the top two channels :/ not sure

Its finally working, it was to do with the ide channels, i changed the sata connections on the motherboard from ide channel 4/5 to 2/3 and it is working fine now.

Well spotted. Gremlins in the box mucking about with your cable connections?

Never mind ... it happens to the best of us.

Good luck.
