Razer blade 15 base 2020 (RZ09 0328) display issue

A week ago while I was playing gtav on the laptop the screen suddenly started to flicker white and black lines then the laptop shutdown i restarted it and everything seemed fine. It happened a few more times then i stopped playing I was busy for the rest of the week untill the day before yestarday when i turned the laptop on it happened again but this the the screen went black the laptop was still on thou. I restarted and everything was fine for a while before it happened again. I restarted again and this time it started flashing white and black at the boot up. Went to the bios to see if it needed an update but it was updated to the latest version. One thing i noticed is that in the bios the problem didnt occur I thought it could be a driver issue I restarted it again and this time windows crashed and said it needed repair, did that but the problem didn't go away. I did a local reinstall of the windows keeping my data everything was fine for a minute or two before it happened again checked taskmanager everything was running fine no issue with graphics card graphics drivers were up to date too. Then the screen went black in bios it worked but as soon i log in to windows the screen goes black. external monitor works fine. Then the laptop wouldn't even power up till today doesn't matter how many times i pressed the power button. It just powered up but the screen is still black the rgp on keyboard is working the fans are working.
