R4 games crashing

A few weeks ago a I bought an R4-III and had no trouble at all with games loading/playing etc. Now while playing the same games the games are freezing/crashing. I was running the R4-III v 3.02 firmware so updated to the newer R4-IIIv.03 firmware..... however still having the same trouble. I then reverted back to the v3.02 firmware and still the same crashing problem (Crashing on Kirby and Phoenix Wright so far). I've also tried formatting the SD card and reloading everything... now I'm out of ideas. I also have another R4 with R4v1.18 firmware that I can play (swap files) around with.Really starting to think I should have gone for the Cyclo....after all this site has saved me a bazillion dollars in games.......Any suggestions would be greatly appreciated.Tracey

I think your R4-III is screwing up, It's a fake R4 so was only a matter of time.

It's going bad definitely.
