He also thinks it may simply be that the ATI card is faulty.

I apologize if I sounded skeptical of his abilities, it just seemed like a simplistic and unlikely explanation.
If the card worked once but was not found on any further reboots, it could be a faulty card or a faulty motherboard. Has he tried to set the motherboard to default to PCI-E as the first video output device? Did your board also have integrated graphics? In that case, it should also be disabled and the framebuffer set to as low as possible or off.
If your system previously has Nvidia drivers, he should have run driver sweeper to clean out any remaining drivers for the old Nvidia graphics card but generally this will not cause the new card not to be found in the device manager. It should still be there, especially as it already worked once.
If your motherboard has of all things, an Nvidia chipset and integrated Nvidia graphics, he might be right and it might just be the least painful option to just put an Nvidia card in there to avoid driver conflicts. I'd recommend the $200 GTX 460 which is comparable but slightly faster than the 5770.

He mentioned some Starcraft players in the forums are having a problem where the demands of the game are causing some cards to literally melt. Has anyone heard of this?

The HD5770 has very low power requirements. What PSU do you have? Ask your tech what the wattage is and the amperage provide on the +12V rail(s).
The issue with overheating was solved in a patch a long time ago. The bug was caused by the menu screens not being FPS (frames per second) restricted so even if nothing was happening it would rending a bazillion frames a second which puts a full load on the GPU.
