Ok so I may not be the most computer savvy person ever but I know a few things but my desktop is winning the battle of the minds at my house. I am the third owner of this machine that was built in 2003 or so. I fried the old motherboard (I think) so I bought a new Foxconn 755/760A01 Series mobo. Here are the system specs: Age of part Foxconn 755.760A01 mobo New AMD 64 3400 Cpu Old 2x1 gig OCZ Pc-3200 3-3-3-8 Ram Old 1 Tb WD10EACS SATA HDD New Ati 9800 series AGP Graphis Card 256 mg Old Power supply is a 480 watt Old Dvd player Dvd Burner Floppy drive Computer does not have an operating system loaded on it yet I cannot get far enough to do so. Computer will turn on and go into Bios and will start up until it says "Disk boot failure insert system disk and press enter." I originally thought it was a hdd issue so I bought a new hdd and now it says the same thing and I have no Idea what I need to do now. I have the hdd connected to the SATA 1 on the motherboard and the hdd is recognized when the machine fires up. Does anyone have any advice on something I might have missed? I am not an expert that is for sure.
