ok, just so you know i did try a quick search of the forums and i did nto find anything.  This is a NEW computer, Dell 8400...3.2ghz, 160 GB hard DRIVE, and DVD RW+ and DVD rom drive.  

My issue is that I was trying to double my RAM as i have 1 GB right now and my buddy had a couple of 512 sticks that he gave to me.  Well they were not the right kind and i ended up not puttin them in as i could tell they would not fit.

After i closed up my computer and STARTED it bakc up i got this message...
Drive 4 not found:  Parallel ATA, PATA-0 (PRI IDE Master)
Drive 5 not found:  Parallel ATA, PATA-1 (PRI IDE Slave)

Then it says Press F-1 to continue or F-something to look at bios.  

Not sure what happened here, only think i can think of is that maybe some wiring got pulled loose because the case opens up from the side and swings out so maybe it was yanked or something but the DVD drive's still get power as they open and close but they are just not recognized in My Computer and do nothing when i insert a CD/DVD.  Any help would be greatly appreciated!

BrianBrian C.......Well I would open up the case and check to be sure the IDE cable which connect the dvd drives is securely plugged in at both the dvd end as well as the motherboard end ........ The problem appears to be with just the dvd drives according to this .........
