I tried to upgrade graphics card in my HPE-510t to PNY VCQK420-PB, but the PC didn't boot (it doesn't pass BIOS screen) after installing new card. So, I put the old card back in, went into BIOS, and disabled slot security on PCI Express slot. Now, the PC won't boot even with the old card. I took off the CMOS battery and put it back on to reset BIOS setting to get video working.
Is this notrious OEM lock of a HP PC? If so, is there a workaround? TIA
