Alright, so yesterday I received my order of: Tagan CS-A+ Curbic Steel Case XFX Radeon HD-489A-ZDFC 1GB GDDR5 GPU/Video Card Corsair CMPSU-750TX 750W PSU AMD Phenom II X4 810 2.6 GHZ AM3 Socket CPU 8 gigs of G.Skill DDR3 1333 (PC3 10600) Ram (2 sets, with 2 gigs per stick in each set) Western Digital Caviar Black WD1001FALS 1TB 7200 RPM HDD (SATA) Sony Optiarc 20X DVD+R Burner Black (IDE) ECS Black Series A790GXM-AD3 AM3 Socket MOBO I have set it all up, but now when I turn my system on, I get a single, short beep from the case (presumably that means it is able to POST?) and a message that says "No Boot Device, Please Insert Boot Device And Reboot" and below that there is a message that says "Insert Boot Media And Press Key". So, assuming that my motherboard is unable to detect my HDD, I try to go into BIOS (which, in my case, is done by pressing the DELETE key on my keyboard). Instead of loading up the BIOS screen, my machine just shuts down on me. I curiously open the case up (I don't have a case window) and turned my machine on to see if I am at least getting any LED signals. The fans on my video card start up, the fans on my CPU cooler start up, all of the visible LEDs light up the interior of the case with green, and everything looks pretty good. However, on my motherboard there are 3 out of 4 small LEDs that flash red for about the same amount of time that the case beeps (once, and for a very short amount of time). They look like this on the motherboard: RED RED gray RED So, what is the problem here?
