So I have a levono m91p desktop I got the msi afterburner radeon hd 6450 card installed it and getting not signal my bios is set to auto detect so I changed it to only detect my onboard graphics to see what's going on it goto my device manager and I believe my card is reading as other device pci serial port I have to install CD for the gpu and tried just installing the drivers from it and still nothing I'm so confused and I'm not some tech savvy guy but from what I seen you should be able to just install the hardware and install the driver
