intermittent bios hard drive detection
Working on my friends desktop computer and the BIOS doesnt detect the haddrive all the time. If i cold boot or reset the machine the harddrive is not detected. However if i pull the CMOS battery and power cord then drain the capacitors (by pressing the power button) and replug the power the drive is detected by the BIOS and starts booting windows (then freezes). The Computer can boot from CDs fine (from IDE cd drives). when i power up the machine without draining all of it's power/ removing the power cord the BIOS gets stuck detecting the SATA drive.
I tried the Hard drive in my machine it and worked fine so i dont think its a drive/cable problem. i also tried one of my known good WD drives in the machine and it doesnt detect it.
i have tried replacing the signal cable
default settings (no options for IDE/AHCI just enable or disable SATA)
i'm not sure if windows freezing is a 2nd problem or part of the first.
Motherboard: Gigabyte GA-k9ns Version F9
Drive: seagate 500gb sata (also tried a WD green 500gb & black 1TB)
thank you for any tips
