Hello!
I am having troubles with my GPU not displaying during the POST and during windows.
My Radeon HD 4850 was working just fine until I tooked it out and plugged in a Radeon HD 4670 to test it out for one of my friend. I was reusing the same driver for my HD 4850 and it worked well.
Booted up my PC this morning and i now have a blank screen. My PC was still using the HD 4670.
The onboard GPU works but not the HD 4670 or the HD 4850.
Here are my PC spec:
Motherboard - Asrock N68 VS3 UCC
CPU - AMD Athlon II x2 250
GPU - AMD Radeon HD 4850 (ASUS version)
Memory - Kingston HyperX DDR3 1600Mhz 2x2GB (the actual speed that I use is 1333mhz)
HDD - Seagate 500GB Barracuda 7200RPM
PSU - Rosewill RD400 2DB
Monitor - Samsung 1440x900 using a VGA connector
OS - Windows 7 64 bit
Having listed my PC spec I will now type out what i have done so far.
-Cleared the CMOS.
-Tested the ATI Radeon HD 4850 and the HD 4670 on another one of my friend's PC and both displays the POST screen.
-Tested an old Radeon x300 on my motherboard and it, to my amazement, displays the POST screen!
-PCIE is the primary graphics in the BIOS.
-I have uninstalled the onboard gpu driver to no avail.
-Checked to see that I have the latest BIOS which I do.
That is pretty much it. I don't think that my Motherboard is faulty nor my HD 4850 as well. Could it be the AMD Driver which I already uninstalled.
Any help would be greatly appreciated.
Thanks.
Also I gave the Radeon HD 4670 back to my friend.
