Sorry sounds like either you didn't your 8350 installed correct or the power supply wasn't up to snuff to handle the chip.. Your FX 4100 was only 95 watts where as your FX 8350 IS 125 WATTS.
I think we can limit it down to the PSU, xjacksssss said he was using it for 10 minutes until it failed. It's most likeyl a cheap (nameless) brand.
