Just finished putting a PC together for my dad with all new pieces apart from using an older HDD and SSD. Go to boot, and the PC powers on for a split second (fan moves slightly and onboard LED lights up for a split second) before the system shuts itself down. Pressing the power button no longer does anything until the PSU is turned off and back on again/unplugged and plugged back in.
However with no Sata storage plugged in, it works absolutely fine and I can boot into bios or windows setup with a USB (but can't install it because I need a hard drive to install it to). If I try plug the HDD/SSD in when the system is on, it immediately turns off.
I can however plug the drives into my PC, and access them with no problems. I even tried plugging in a brand new SSD into the problem PC and it has the same issue, so surely the problem isn't with the drives themselves, but yet without them in, the system will post..
Any ideas?
