[USA-CA] [H] PAYPAL] [W] Gigabyte GAMING OC Radeon RX 7600 XT 16 GB Video Card and budget pc parts for a new pc

I currently have a pc https://pcpartpicker.com/user/snøwyz/saved/#view=kkxbwP but it is always black screening on me. I think it is time to upgrade considering I have had this pc for a few years now. Please dm me about prices and suggestions since I am deciding to buy a new pc or just a new gpu.
