Video Card Killing Motherboards?

I have an HTPC with a micro atx Gigabyte Mobo 780G (GA78GM-S2H) that I have just RMA'd for the second time since December. The first board actually caught on fire! Flames and all! Fortunately nothing was damaged except the board and the PSU. Yesterday my system rebooted suddenly and this hideous clicking noise came from the speakers. Thank God my Radeon 4890 wasn't fried. I stripped the system down, reset the CMOS, tested the memory, used and eventually determined that the onboard video no longer works, and who knows what else happened. Thankfully Gigabyte has an easy RMA process. Too bad I won't be using that model again...I am just going to sell that schitt like so fast!

I am doing a slight overclock on my video card (900Mhz, it shipped clocked at 875Mhz), the cpu and memory are at factory settings. Is it possible that this beast of a video card pushed the board too far? I wonder if anyone has been in a similar situation. Going with an ATX board is a no go for me because its gotta be hidden behind my tv.

Can someone recommend a solid micro atx board for AM2+ ?
