Radeon™ RX 550 Graphics card in seven year old HP Pavilion p6-2033w
I tried to install a Radeon™ RX 550 Graphics 2 GB GDDR5 dedicated memory card in my seven year old HP Pavilion p6-2033w Desktop. Light comes on but won,t boot. Monitor stays black. Had Windows 7 originally now has window 10. Motherboard is IPISB-CU (Carmel2). I ran the hp diagnosics utility, everything passed. I tried to update the BIOS at hp.com but can't. Any suggestions appreciated. Thanks!
