hello, Recently I change some settings in my bios, I enabled the Secure boot and disabled the Legacy Boot in my HP Z440 Workstation. But After that it beeped 5 times and Red light. After getting that this is a ram issue I changed the slots, Now there is no beep or red light. Everything looks Normal. but no display output. I tried to cmos reset. Removed the cmos battery, But no luck.
My PC has Quadro 4000 GPU. I tried every type of Cmos Reset but it didn't Help.
