trouble starting up

the fact that my computer fell makes it seem like a hardware issue however because it is in RAID 1, that the internal diagnostic programme found nothing wrong, and the fact that the hard drives aren't in the back where it fell makes it less likely. also how efficient is RAID 1 at fixing problems with the hard drive? though i have only used the programme after the RAID software had rebuilt the drive might have something to do with the diagnostic programme stating that there was nothing wrong with it. should i reinstall windows and immediately wrong the diagnostic programme?

also could it be that the internal diagnostic programme is just not finding the error? the diagnostic programme doesn't work probably due to the fact that it is a RAID 1 setup. i checked the WD website and they don't have a RAID 1 diagnostic programme.

Anything is possible.
But look at the facts, you dropped the computer and then problems
Code 24 hardware

I can only guess, but raid, diagnotic problems and everything else, I still have to go with hardware.

so i should get them replaced. then here's the question seeing as how only one showed the error message can i just replace the one or do i have to replace both since they are in RAID?

I dont have the answer to that one

Does not refer to your problem, but has lot of nice ideas.

alright so here's an update.

i bought a new Hard Drive same make and model, it got rid of the error message at start-up however it didn't get rid of the BSODs during the installation of windows so i took the new drive out thinking that was the problem so that it would run off the secondary Hard Drive however i still received the BSOD referring to the BIOS.

Bottom line on BIOS, if you are not qualifyed to make changes to the BIOS get a professional. I do not have enough experience to give advice in that area.
Most here agree, it should be left to a professional

so would a computer repair shop work or does this mean i have to send it back to dell?

Dell, reapair shop; it depends on who works on it
If you have any sort of warranty do not let anyone other than Dell touch it or warrantywould be void
If no warranty, its up to you. Go to where you feel most comfortable. Speak to some kids they know who is good.
