Hi I've been having some problems with this laptop I have,
what happens is it starts up, the CD drive clicks, then turns back off an starts up again. This happens over an over, although occasionally if your lucky it will actually start up fine.

When it starts up fine everything works perfectly so I don't think there's anything wrong with the hard-drive, but after a random amount of time it will turn off.

When it does the start up click, then turn off part the screen stays completely blank, so it does it all before the splash screen appears, so I can't go to the BIOS or any F keys and I can't get it to load up from a CD either.

Its an Acer Aspire 5520 Laptop (worst thing ever!!) but yeah any help would be amazing!!
