internal sata drive stopped working

ok, so i was installing a few things and my machine would freeze up when it was testing the install. after waiting about 5 minutes i decided to hard reboot my machine. my sata drive is no longer detected by the mobo. it acts like its trying, but then just skips after around 2 minutes. detects my ide drives just fine. no matter which sata slot i put it in the same thing happens. drive is spinning. windows will not boot from an ide drive if the sata drive is plugged in but will if it is not plugged in. what is my next step in determining where the exact problem is and figuring out a resolution?

 

If you have problems after an install inside the PC, then look for loose connections you may have bumped. Sata drive connectors are easily knocked out of wack, especially the earlier versions of the cables.
