Boot to a USB stick with LINUX on it and then you can run diagnostics and eliminate or confirm whether problem is a hosed LINUX kernel or problem with hardware.

What Linux distribution?

When the Grub boot menu shows, have you tried a previous kernel version to boot from? Maybe an upgrade has broken something, and a previous version may still work.

What changed, and surely you have some event logs, screen shots, or something else.  There simply isn't enough information to go on so really nothing can be eliminated from a bad memory chip to a munged data file or a perfectly good binary with incorrect permissions.

We'll never get to the bottom w/o more information ... unless you're just willing to try everything that it could possibly be, one at a time, over the next gazilion years.

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

When you boot the system, you should have a Grub boot menu where you can select different options to boot from. Here you should have a list of different kernels, and you can scroll to the one you want to boot from. Sometimes if you don't have that boot selection when starting to bootup, you may have to press "ESC" to get to the menu selections.

What distribution are you using? What are the first messages you get on the screen after the PC has gone through post? Have you pressed ESC several times right after post?

I've seen system panic on boot up before ... it was a motherboard failure. If you have some equipment that can test your motherboard, do so.  Otherwise I suggest taking the computer to a PC shop that has the equipment to test the motherboard and possibly replace it if necessary.

There isn't any magic software that can fix this.  You need hardware diagnostics and hardware that can test other hardware.

I mean before the panic. There must be messages on display before that.

This seems to be a hard drive or lvm failure, try running fsck. If you have a full backup simply replace the disk and restore the backup.

I would investigate also the hardware, performing full hardware diagnostics against the machine would help to rule any hardware issues out.
