PC Boots Into Windows But Cannot Access Bios

[Nick-072]

Hello got a bit of problem, I have an old....very old Acer X3200 desktop pc. AMD Phenom x3 chipset !!! Anyhow to be able to boot into bios once i had to press DEL preboot. Running Windows 7 , Windows runs fine. (* I know this is an 8 / 8.1 forum my other PC runs 8.1 which i why i joined *) Recently I installed a Crucial MX500 250gb SSD, and thought about putting in a pcie SATA card for a little boost. Anyhow now when I press DEL , I get a message saying "ACHI BIOS installed!!" but wont go to the menu!
I have Flashed old Bios, Flashed later Bios, reset Bios (by removing CMOS battery), Put old HDD back in and trying again, I have run SFC (no problems found), tried ">wmic bios get /format:list" (incorrect perameters),
I only use this PC as a DAW for recording guitar and drums i am hoping to get another years use out of it, so apart from setting fire to it or throwing out of a window (like most Rock N Roll equipment) any suggestions??? Thanks , Soz for it being long winded!!

"ACHI BIOS not installed!!" wtf?? at least it boots into windows!.....for now!!!
