If it was a SSD based system, perhaps you didn't plug the SSD and main HDD back into the same SATA ports. I've seen many systems misconfigured when the user incorrectly "added" an SSD to their system and just plugged it into the next available SATA port, instead of evicting the main HDD from the SATA1 port and connecting the SSD there. Then, when they installed Windows, the bootloader (BCD) was written to the primary SATA device (the HDD), while the OS was installed on the SSD by user choice on the drive selection screen. Now, disconnect and move everything to a different case, correctly connect the SSD to SATA1, and in certain configurations, you'll get the "No bootable disk found, please insert system disk and press any key _" message. However, the bootloader can
be moved to the SSD—I've done it.

I know it was a very well intended comment, but I'll take this opportunity to gently mention PassMark's benchmark page
again. Using their benchmark information, you can get a good idea of how different CPUs, HDDs, and video cards compare—before buying. In this case, his original i5-750
gets a score of 3730
, while a i3-4130
(similar to his new i3-4140) rates higher, at 4864
I second other people's comments here to check the power supply. If you don't know how to do this, let us know; there are several of us (including myself) that would be glad to give step-by-step instructions in necessary.
