Can a Radeon HD 5770 turn into a 3000 overnight?

NZXT Lexa S case
Microsoft Windows 7 Home Premium 64 BIT
Corsair 16GB XMS3 PC3-10666 1333MHz (4x4GB) ram
ATI Radeon HD 5770 - 1 GB - (PCI-E)
Asus M4A78LT-M (AMD 760G) - VGA
Corsair Force Series 3 240GB SATA 3 6Gbs SSD
AMD Phenom II X6 1100T (6 x 3.3 GHz) AM3 9MB
500G Western Digital Caviar Blue SATA

I have been running this system with no issues for 18 months and closed it down last night with no problems.
Booted up this morning and it was completely dead. No fans. No LEDs. Nothing.
Figured it was the PSU so swapped out the old one with a new Corsair CX750M which I had. Switched it on and it sounded like it was booting up ok but my dual screens remained blank, though I could hear the windows startup chime.
I swapped over the DVI cable from the GPU to the Mobo socket and there was windows with a dialog box "No graphics driver detected". After a quick check there seemed to be nothing else missing apart from a corrupted printer driver, so attempted to re-install my current graphics driver which I had on file. It blue screened half way through. Un-installed and re-installed twice with the same result.
Now this is the weird bit. I checked in the Device Manager and it now states I have a ATI Radeon 3000 instead of the HD 5770 !!!!
This might account for the driver crashing?
Anyway, I have un-plugged and re-seated everything and even installed the driver for the 3000 (which didn't crash) but still can't get any output from the GPU.
Any ideas on what the problem is? Mobo or GPU or something else?

You only get display output going directly from your motherboard right? Well your motherboard has an integrated ATI 3000 GPU. That explains that, try pulling out your GPU, cleaning all the dust off (if applicable) and firmly reseating it in the slot.

Try clearing the CMOS. Unplug the machine, remove the CMOS battery, move the CMOS jumper to short, put the battery back in, move the CMOS jumper back to normal position, plug machine in, and hit the power button. Have the monitor hooked up to the 5770. If still no display then one of two things, dead PCIe slot, or dead GPU.

One thing do you get any video with the HD 5770 before you get to Windows? Like during the post test before Windows would take over. From the description you posted it looks like you were not in which case it would not be a Windows or driver problem in the first place so best guess since you have already reset the card would be bad socket or card.

Stickg1,
Thanks for the heads up on the integrated GPU, that explains the missing 5770.
I cleared out the CMOS as instructed but it made no difference, so I swapped out the 5770 for an old 4770 I had in another system and that booted up perfectly, so I can only assume the problem is down to the GPU.
It's not a big issue as I have been thinking about upgrading to a 7770 for awhile.
Do you think the PSU failure caused the GPU to fail or could there be another underlying problem lurking within the system?
Thanks for the help so far.

PSU Failure? Was there a power surge or something?

The GPU could have just died, they don't always run forever. I think it's just bad luck this time.
