I'd try running a diagnostic on that drive, Hard Drive Installation and Diagnostic Tools - http://www.bleepingcomputer.com/forums/t/28744/hard-drive-installation-and-diagnostic-tools/

Have you tried booting without the drive attached?

FWIW: When chkdsk runs at boot...that's not a good thing. It means that the drive is in dire need of a chkdsk, for whatever reason. For me, it's my signal to run a disk diagnostic on that drive (since I routinely run chkdsk /r and should never have it try to run at boot).

I see No Signal on my screen when my system shuts down and then the power goes off inside the box.

The monitor itself still has power, but is not receiving a video signal since the box is not running. After a minute or so, the monitor figures it out and switches to power saving mode and the message goes away.

When you see No Signal, is the box still running (can you hear the power supply fans), the necessary lights are on, etc. If yes and you still see No Signal, the monitor is not getting any video input. Could also be a loose cable, so unplug and replug them.

If the video card is separate (plugs into the motherboard), reseat it and check all the cables are snug (power off of course). You can even move the video card to another free slot if there is one. Maybe it got undone somehow in your other repairs.

Or... if you are running a chkdsk and it takes a long time, the system could be cutting out the video after some period of inactivity as part of your Power Settings (by design). When you see the No Signal and if the system sounds like it is running, move the mouse around or press the space bar on the keyboard to see if that wakes it up.

The mediocre teacher tells. The good teacher explains. The superior teacher demonstrates.
