My HP Z420 has a fatal problem, I entered bios settings and disabled and re-enabled ATS Support (By fault). I then rebooted my PC and when it came to the Windows login screen I touched the keyboard and sudden reboot, I taught that it was a tripple fault. When the PC booted it showed a message with an error beep " Code: Fatal TLB error in CPU 0
Then the PC shutdown. I powered it up multiple times after this, and the screen won't show, the cooler startup noise that it makes for a second is not present, like the CPU is stuck in an infinite loop. I tried a CMOS reset, and nothing changing. When I kept it for a while the CPU keeped working until it heated and I started hearing the cooler accelerating...
Please I need help !
- I am not really sure that disabling it applied, but it had with it another 2 ATS features and they were disabled. I think they were enabled before.
- I didn't run my OS before this.
- Also previously, enabling secure boot would make an error beep and CMOS reset will make it work fine.
- I tried CMOS Reset button, removing CMOS battery for 20 minutes but nothing changes.
- I hear a low volume high frequency sound, I guess it is the PCI bus ??
IS IT OVER ??
