Folk, I am building a new PC. Components: Thermatake Armour Series ATX Full Tower Case, Thermaltake W0116RU 750W Power Supply, Intel D975XBX2KR LGA 775 motherboard, Intel C2 Extreme X6800 Conroe 2.93GHz processor, 2GB OCZ DDR2 800 SDRAM, ATI FireGL V3400 128MB GDDR3 Video Card, SEAGATE Barracuda STE 3250620AS 250GB 7200 RPM SATA 3GB/s Hard Drive, VIGOR Gaming CLT-M21 92mm Thermal Electric CPU Cooler PLEXTOR 52X CD-RW IDE Drive. I have assembled the above components, and fired the PC up. No Post errors, No flames, No Smoke. The Bios recognizes the RAM and HDD, but upon boot up, the following message scrolls onto the screen: " INTEL BOOT AGENT PXE PXE-E61 Media Test Failure, Check Cable. PXE-M0F-Exiting Intel Boot Agent. No Bootable device Insert BOOT Disk and press any key" I ran the XP professional Installation CD and upon completion of loading, XP indicates there is no HDD present or words to that effect. I did swap out the SATA cable connected to the SATA HDD, I tried connecting the SATA cable to a different SATA port on the MB. No change in the result. I suspect that I have missed something in the BIOS setup, but am a newbie when it comes to the SATA setup. Any suggestions would be greatly appreciated! If I posted thread in the wrong forum, please forgive me. Yours Truly Fly'n_Blind!
