New System w/ Radeon HD 6450 and Radeon HD 5450 Need Help

Asus mother board. Radeon HD6450 pcie x16 card and HD Radeon 5450 pcie x1 card. I want to run 2 monitors on each card. Installed both and the HD4650 installs the software and drivers. Install second and at first got BSOD. It installed but shows as video controller (VGA compatible).
I go into the AMD Vision Engine Control and the two monitors on the HD 6450 show up and the monitors come on and work. It shows the other two monitors, but I cant tell how to turn them on. I use the "extend" option and the working screens flicker, but nothing out of the other two. The show up on the software but I cant activate them. I would greatly appreciate any help you can offer, it's about to drive me mad. Thanks

I just wanted to let the room know that I uninstalled and reinstalled the Radeon HD5450 and it seemed to identify it. All 4 monitors are working fine but my NIC card quit working..still working on that one.

does happen, the 2 cards don't work in crossfire or at least shouldn't but as stand alone cards should work just fine.

the nic issue is another matter, did that happen after the bsod? or when you installed the second set of graphics drivers?

or when you installed the second set of graphics drivers?
Shouldn't have to install the driver twice as both cards use the identical driver.

One thing that would help is filling in your system specs,

The NIC stopping working (card or onboard?) could also be a motherboard issue depnding on how it is configured with regards to the PCI-E 1x slots.

NIC Adapter

It was one of those things where you do a couple of different operations and then you notice somewhere along the line , something changed. I think it was caused by the BSOD. I've read endlessly and finally pulled a USB internet adapter (looks like a thumb drive) out of the drawer and used it. Some things are just above my abilities. Thanks for answering. Everything has worked out and it was all due to driver compatability.

3 Monitors HP2311 - Radeon HD 6450 - doesn't work.
I just bought a new system and I am not very technical. My graphics card has DVI, HDMI, & VGA ports (no display port). The monitors have the same 3 ports, so I thought they would work, but it seems like the system will only recognize any 2 of the 3 monitors. I have been told that I either need...
