Screen black and flashing

I've had my asus vivobook pro for maybe 4 months. The past 2 days I've noticed that my screen just isn't turning on. The keyboard lights are on, I can hear notifications, fans are spinning, no screen. Sometimes it will appear for a bit, and then flash away again. Ik I need to update drivers (I updated them a month ago) but I cant see to update them. I've tried the shift+windows+ctrl+B to no avail but a beep sound. I need my laptop for work and im getting really anxious about missing deadlines. This thibg was also just so stinking expensive I cant just buy another one.
