If it reboots fast, but takes a long time to reach the BIOS in a cold boot, it's probably the PSU as I mentioned earlier.
Rocketfish is a very poor brand and I would not be surprised, because it's made by one of the very worst manufacturers of PSUs ever: Huntkey. It's taking that long to warm up and produce stable power. Take it back to Best Buy and get an Antec.
now when i reboot it, it takes the same time as when i cold boot it. Ill try getting a new psu today and post back
