Asus Rampage Extreme VGA BIOS error
 

My friend have an Asus Rampage Extreme (775 socket) and it started to get "VGA BIOS" error on the LCD Poster. He is running an Sappire 4870x2. I started by swapping it with an AMD 5450 or something similar single slot GPU that doesn't need additional power. The problem went away and then I reinstall the old 4870x2 with a new Antec 520W and the problem came back. Am I looking at a dead GPU or is it not sitting properly? Also, he's old Zelman PSU seem a bit broken because when I turn off the PSU switch, there's still power going to the motherboard as all the onboard LEDs are still on.

EDIT: When I manage to boot into Windows, there were a lot of GPU related errors in Event Logs and he complained about BSOD as well.

look fore dust in the gpu blow out with compressed air. take shroud off and blow fan and heat sink.
heating issues ??
need a 650 W or more that GPU also good one if he has the cash.

take down bios settings then reset it by remove wall outlet cord then hit start button then reset cmos

yes it mite be pci-e power issues

Well I fixed it. I read on another link that it could be not sitting in the slot properly. Since I had to force the card up a bit to align it with the case screw holds, I suspected it may be out alignment despite it's all the way into the slot. I unscrewed it and it booted right the way. Unfortunately, I removed it since I couldn't trust that Zelman PSU as it would pass power the motherboard even with the back power switch set to off.
