I recently got a new computer, I have had it for about 5 months now. I got it for free so i'm not too worried but I'm wondering if its the top slot on my motherboard or its BIOS locked. I'm using an A8-5500 Quad-core with 8 gb's of DDR3 1600mhz and an OEM board. I have an HP Pavilion p7-1534 deskop and I recently decided to get a dedicated GPU since it has an open 16x slot. I bought a GPU and popped it in and I got a beep code, I don't remember how many beeps but it was for expansion card failure, the fan on the card spins up to full speed but theres no video outs. I thought it was the card because I got it for cheap on eBay, but I put it in my old system and that one boots just fine and has video outs and everything, I tested the GPU by pinning it at 100% by mining on it for awhile and it didn't crash or anything and the drivers installed just fine. Wondering if the slot on my board is dead or if it's something BIOS or software related locking the slot, since I can lock all my PCI-E slots in the BIOS.
