Hello I'm new here  And I'm having trouble with my new build

Config:
Intel CORE 2 Duo E7300 (2.66GHz)
ASUS P5QL-SE P43 MotherBoard
HIS HD4670 PCI-E 512MB DDR3 IceQ Turbo
Kingston DDR-2 800MHz 2G Ram
WD 640GB 6400AAKS SATA II/16MB HDD
ANTEC EA280 EARTHWATTS 380W

I'm using my old IDE DVD-ROM (DVD DC DW1670 from BENQ)
When I put the Win XP disc in the DVD-ROM,
it said "CDBOOT: Couldn't find NTLDR",
followed by "Reboot and select proper BOOT device
or insert boot media in selected boot device and press a key"
I have tried different discs BORROWED from my friends,
and it just showed the same error.
I also tried the discs using another computer and they work fine.
So what's the problem here?
Is it my IDE DVD-ROM? Or the new HDD?
Thanks in advance!

P.S. I have SET the DVD-ROM as the 1st boot priority
More likely to be the DVD-ROM drive. Do you have a spare to swap in for your current drive?If the problem doesn't follow you (taking the disks to other computers and they work on them) then the problem is the drive / cable.

Re-partition and format and see if this works.
