* I'm using a fresh installation of Windows 7 64-bit.* I have 2gb DDR2 SRAM.* I have an Abit SG-95 motherboard (PCIE X16 1.0) with the latest BIOS from Abit which is 11-20-2007.* My power supply is an Hec HP485D 485W ATX12V.* XFX ONE R-Series Radeon HD 5450 1GB DDR3 (PCIE X16 2.1)When I try to boot the computer all I get is a black screen and the computer locks up.  If I remove the Radeon, change the BIOS setting "Support PCIE Multi Adapter" to Enabled, and put the Radeon back in my computer it will boot Windows but only in 640x480x16 video mode.Device Manager tells me "Your computer's system firmware does not include enough information to properly configure and use this device.  To use this device, contact your computer manufacturer to obtain a firmware or BIOS update. (Code 35)".I have tried installing the Catalyst 12.4 drivers from the CD, and I uninstalled them and tried the latest ones from the AMD web site.  It always stays in 640x480x16 video mode.I believe the problem is because my motherboard is PCIE X16 1.0 but the Radeon is PCIE X16 2.1

Quite possibly, that is quite an old motherboard and a really piece of ***** power supply. If you aren't a heavy gamer, which judging by the HD 5450 you aren't, take a look on Newegg about putting together an AMD A6-5400K based APU system. I put one together for my uncle and I can say I was quite impressed with the power of that inexpensive system.
