[QUOTE=nemesis688;2479531]It took me a bit of searching but I believe my motherboard is a MS-7184 (AmethystM). I found the specification at the HP website (http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00378480&dlc=en&lc=en&cc=us)
I havn’t tried to update the BIOS and theres no warrenty, the computer is from 2005.
The computer is a HP Pavilion a1250n. It was working fine then one day I turned it on and it was saying there was no hard drive connected.[/QUOTE]
I would check to see if your connections between your HDD and mobo is connected firmly. Cause over time connections do work themselves loose as to why can be a number of cause being old and if you opened the case and dislodged a connection and didn’t realize it. So go back and update the BIOS if there is a new version and clean and dust out the inside of the computer as well as check all power and hardware wire connections are connected and tight. And then turn your computer back on again. But as you mentioned how you connected a IDE to you computer and it worked so that means it still a working mobo for now but did you hook your sata drive to another computer and see if it sees the sata drive and if it doesn’t that means the drive is no longer working. You didn’t mentioned whether the sata was the main HDD or not?? If it is then just hook it to a working computer with a working main HDD and see if it will detect and broswe the HDD from you computer. That is one way to test if the sata HDD is still working. Beyond that if the sata ports did fails you still have the IDE but since everything is going sata it might be time to decide whether to get a new or build a new computer that will still work.
