I have a Dell Optiplex GX620 and I just installed a new Samsung 840 EVO 250 GB SSD drive. When I boot the system it begins to load from the Windows 8.1 DVD, displays the logo on the screen for a few minutes, then displays some error message briefly and reboots. I have no other drives just the dvd and the sad, I have removed all but one 2gb stick of memory, pulled the add on video card, and reset the bios (which is the latest A11) to defaults. The bios sees the drive. Nothing seems to work. Any ideas?
