I tried installing a Geforce GT 610 on my Lenovo H500s, but my monitor just comes up blank! I had a feeling that it was a problem with BIOS, so I went in. The only options related to video were: PEG, IGD, and AUTO. I have tried all of these but still, nothing. My monitor still works when the graphics card is disconnected, so it's not the monitor or a faulty cable. Any help is appreciated! Thanks -Oliver
