got a weird problem that i cannot seem to solve, last night i disassembled PC, to find two of my RAM modules dead. anyways thats not the issue at hand, after reassembling, everything connected in right place with right leads, etc. it POSTs fine but then, since im using a new hard disk i am trying to install windows vista again but i cannot seem to get PC to recognise my DVD-ROM drive, its IDE drive connected to the only IDE port on my motherboard, could this be a BIOS problem or something more serious? should i try pulling CMOS battery and clearing CMOS, might that work? thanks to anyone who can assist
