Installed Win 7 64 Bit from USB Recovery and Optiplex 780 constantly reboots
I just received a new recovery USB for windows 7 64 bit. Prior, I had windows 7 32 bit and wanted to install the 64 bit operating system for the higher memory. So I went through the motions of installing the new operating system, took out the USB drive, and the Optiplex 780 is in a constant loop of rebooting itself, never even getting to Windows. It's like an endless loop of rebooting with no Windows logo showing up and what appears to be an issue with the hardware and the new operating system. Any help/suggestions would be greatly appreciated. Thanks.
