I have a Gateway 550GR that I am having a strange problem with. I installed a hard drive from another computer that I had that died to get some info off it. It has two slots for SATA drives. I removed the DATA drive, plugged in the hard drive from my other PC, unplugged the boot drive, and booted into windows. No problems.
This evening I had to move it back to its location, so I replaced the original hard drives, moved it, hooked it up, and now when you hit the power button, it doesn't remain on.
Upon pressing the power button the fan in the case and the CPU fan both come on, as does the blue LED for the video card. But as soon as you let go of the power button, everything shuts down.
Also, the hard drive light under the power button blinks when you press the power button down.
Between the time that I replaced the hard drives and moved the computer, nothing abnormal happened. No drops, no shocks, no pulls or pushes. Everything went fine.
Any ideas?
