[QUOTE=bean55;2787004]Are both connected to the MOBO or a add on graphics card ?
Still could be connectors going bad, try a add on graphics card if not using one now
Or drivers just not loading if the bios stuff is seen as booting up.
Did you replace it in the same slot, perhaps the slot is worn out or going bad, did you try another SATA slot ?
Next thing to look at is the PSU perhaps it is going out and not providing the necessary power all the time.[/QUOTE]

New graphics card.

Drivers loaded from CD that came with card.

Checked the PSU with my PSU tester and the only thing was the 12v showed up as blinking L.L, but I have another computer with the same PS that shows the same thing and it works fine. Thanks.
