I am building a computer for a friend and am having problems installing windows. specs: ASRock 775XFire -eSATA2+ mobo Pentium D 2.8 processor 1 gig DDRII 533 AOpen 6600GT 128mb graphics card Seagate 250gb SATAII 300mb/s Lite-on DVD-RW IDE after installing all the parts I turned it on and it posted and asked for a operating system... in post it recognized the hard drive... I put in a windows xp cd w/sp2 and started setup. it loaded all its stuff and then asked as to what I wanted to do. I chose to install windows xp and it said it did not detect a hard drive. I tried several times. In frustration I installed it into my computer and installed windows on it without a problem. I put it back into the new computer and attemted to load it. It posted and began to load windows but imediately there was a flash of a blue screen (it went away so quickly that I could not read any of it) and it rebooted... it did this several times. I tried different SATA cables and even tried booting with another hard drive but to no avil... the same outcome appeared. I am pretty much unsure of what to do now... any help would be greatly appreciated.
