Reboot and Select Proper Boot Device...after reboot?

Hello all. Getting a little frustrated here. A couple of weeks ago we had a user come in on a Monday morning to find that her pc was displaying the classic message "Reboot and select proper boot device...". Tried popping in a windows disk and fixing the MBR, no luck. Ended up reinstalling windows and her few programs back on it. All was good after this. For about a day. She came in the next day to find the same message. So at that point we decided that more than likely the drive was bad even though oddly enough it tested out fine. It was a Corsair 60gb SSD.

Last week we swapped that Corsair with a 64gb Crucial SSD and installed Windows. We then created a backup image of that drive. All was good until Thursday when her power strip that the PC was plugged into got tripped. Start up the computer for find "Reboot and select proper boot device..." message. So, apply the backed up image to the SSD since repairing the MBR didn't work.

Now this morning she comes in and the PC is running fine. Attempts to open Microsoft Word and she gets a pop-up stating there isn't enough disk space. So, she then restarts and upon booting back up gets "Reboot and select proper boot device..."

Any ideas what is causing this? Is it something with the mobo or do I just have horrible luck and replaced the bad SSD with another bad SSD?

 

reboot and select proper boot device

Alright whenever I try and boot to my SSD (boot drive) my computer will end up saying "reboot and select proper boot device or insert boot media in selected boot device and press a key". However if I use the same SATA and power connections and attach my Linux hard drive, with no changes to the BIOS, it will boot just fine. If I have my SSD set up as a slave drive, I can access the files fine and browse the drive as if nothing is wrong. Anyone know why this is happening?

Specs:
Mobo: ASUS M4A79XTD evo
CPU: AMD Phenom II X4 965
RAM: 2x(2x 2GB A-Data Gaming Series)
SSD1: Kingston SSDNow 64GB
SSD2: OCZ Onyx 32GB
HDD: WD Caviar Black 640GB
Linux HDD: Hitachi Deskstar 320GB
DVD Drive: Some LiteON drive
Graphics card: AMD Radeon HD 6950

If anyone has an idea as to why this is happening, please let me know. The system has been working fine up until I took it apart earlier to clean it out.
