My rig:
CPU: FX-8350
MoBo: M5A99X Evo R2.0
PSU: Xfx pro 1000w 80+ platinum
GPU: 2xGTX 680
Cooler: Corsair H100i
RAM: Kingston hyperX predator 1866mhz

I thought to overclock my 8350 to 4.6Ghz. so i took a little research and found out that 8350 runs at 4.6ghz in a voltage of 1.4. so i watched a tutorial first how to overclock the 8350, and i first overclocked to 4.4 at stock voltages and it was stable and i kept it running prime95 for 20 minutes and nothing wrong. So i thought to take it to 4.6Ghz with 1.4V and when i booted my pc and first checked the temps and the cpu was at 39C. so i opened prime95 my PC blue screened.
after that i thought to come and ask the community what should i do.
ps. i dont know much about overclocking.

Perhaps you have a bad chip, some chips will be inherently better than others from the day they're manufactured. It's just he luck of the draw. Just because someon on the internet says you can get exactly X GHZ on X voltage, doesn't mean that it'll be the same for you.

It may boot to 4.6 GHz @ 1.4v but in my experience you need a bit more voltage than that to stay stable. Try going to 1.45v CPU core and see if that improves stability.

Also, make sure your CPU NB has a small voltage bump. In particular, boosting CPU core voltage but ignoring the CPU NB voltage will not work. The FX 8350 usually needs the extra CPU NB voltage brought up to 1.25-1.30v or so.

If you are pushing the motherboard NB and HT, you also want to give them around 0.025-0.050v more, capping around 1.15v NB and 1.25v HT.

Make SMALL changes and test. Keep temps and voltages in the safe range.
