I have a home built system that has been in use for several years with no issues. I decided to upgrade my Windows 7 HDD with an SSD. I cloned the HDD using Reflect via USB. The drive and its files were visible in Windows Explorer so the drive should be working. When I swapped the drives the PC failed to post. Fans came on for 1/2 second and then switched off with power light on. After checking connections and removing cables i mistakenly reconnected the old drive and the system booted normally. I have checked cables, I reset the CMOS, disconnected all drives and the system boots to the BIOS. Now I tried connecting the old HDD by itself and no dice. No post again. Any ideas?
