Hello!
Purchased a HP Z800 tower yesterday. Installed W10 and flashed the newest BIOS on it. Everything worked flawlessly until I noticed hyper threading was off. This is when I tried to access BIOS on boot but noticed none of my keyboards were usable. I tried to reset the BIOS with the on-board physical button, which worked, but the system prompted a series of error messages such as time, asking to confirm with "F1".
I had to drive over to a friend to use his PS/2 keyboard to have control of the BIOS. Now I can control the BIOS, but all my boot drives are gone ("no bootable disk found"). I tried to reset default settings via BIOS, which is when I started having loss of signal issues. Now I need to remove AC to get the PC to display signal after boot.
When I get a signal, the following occurs:
POST -> RAID window -> LSI MegaCorp -> no boot disk, press a key
I tried to use another BIOS, but I'm unable to downgrade. Everytime I use DOS-Flash USB via BIOS I get "error flashing system rom". Only re-flashing the current 3.61 works without an issue.
What am I supposed to do? I'm very limited configuration-wise because I don't have a PS/2 keyboard, so every time I want to try something I have to do it elsewhere. Boot options are IDE / RAID+AHCI, tried both without success. I've tried to run with a single RAM stick but the lack of signal is still present. My GPU is GTX970, could that somehow be an issue?
Boot block date is of the newer one, running dual E5620.
