Some days ago I bought a GeForce 8400 GS Graphic card.
My computer satisfied all the minimum system requirements it required. After installing the Card in PCI Express Slot I started the computer. But it now hangs at the POST screen i.e.(the first screen when the PC loads).
It hangs at Checking NVRAM.
I had checked the graphic card on other PC and its works perfectly. So I think there's no problem in the Graphic card.
If I remove my graphic card and run my PC with built in Graphic card, my PC works and doesn't hang. I upgraded my BIOS but still no fruit. My PSU is of 400W and there no problem in it.
Do I need to disable RAID or is it the problem with my RAM?
