I installed my intel 520 SSD about two weeks ago without much trouble, and it ran smooth until now. I was working on my computer and it cut to black instead of a blue screen, and upon restart the drive is not detected. More specifically upon reboot I'm given "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key". I've checked boot order, no usb, no cd, disabled my other hard drives, checked my power and SATA connection and I keep getting the same aggrivating outcome. I'm assuming the drive crapped, but I'm posting here because I hope I'm assuming incorrectly.
I'm running Windows 7 x64, and it died in session with only Chrome running.
I has same issue as ur problem. Here problem is reset motherboard bios to factory setting and then reboot. There go.
