Detailed description:

I started experiencing an issue just after Christmas when the screen would not turn on but there would be a flicker on the lower screen, and the power light would be on and it warms up and you can hear fans cooling. Restarting it by holding power button for 10-12 seconds turned it off. then turning it on again it would not show the ASUS boot logo. Trying the other reset by holding the power button for 40 seconds, would not work either. It has done occasionally, and i have been able to work on it, but yesterday and today it would not start up at all.

I recently upgraded it to Windows 11, as the windows checking tool said it was ok to update, didn't think anything of it. And it worked fine for about 2 weeks. No updates that I recall.

Helpdesk advised i should try downgrading it, but that didn't work either. Managed to get it started yesterday, went to do a fresh install of win 10, but it failed twice, right at the last installation stage, about 20-30%. Thought i would uninstall Bitdefender security to see if that was stopping, but it wanted a restart, and guess what, not starting up. I must have tried to start the laptop at least 50 times today. Not a Asus logo in sight.
