1.Power Supply Testing
This is the #1 suspect given your boot failures and load-related crashes.
Test with a higher-rated 12V/4A+ power adapter (the stock unit may be borderline).
Measure voltage during idle/stress using a multimeter (should stay above 11.5V under load).
2.BIOS Update
Please press delete key as soon as you turn on the PC, so that you can go to BIOS. Please send us a picture of the Main page.
We will check if you need to update the BIOS.
3.SSD Health Check
Run SMART tests:
bash
smartctl -t long /dev/nvme0n1 # Replace with your SSD device
smartctl -a /dev/nvme0n1 | grep -i “error|fail|wear”
Replace the SSD immediately if errors or high wear are reported.
4.Kernel Parameters (Test these one-by-one)
Edit /etc/default/grub:
ini
GRUB_CMDLINE_LINUX_DEFAULT=“… intel_idle.max_cstate=1 processor.max_cstate=1”
Add one of these if needed:
iommu=off
idle=poll
tsc=reliable
Run update-grub and reboot.
5.Proxmox-Specific Adjustments
VM Configuration:
Set CPU type to host or kvm64 (avoid qemu64).
Disable ballooning in VM memory settings.
Hypervisor Tuning:
Add to /etc/modprobe.d/kvm.conf:
ini
options kvm ignore_msrs=1
options kvm-intel nested=0
Run update-initramfs -u.
