Can you give us your hardware components such as the make and model of your power supply and the watts, amount of RAM, your cpu, and video card? Is this a new system?
 
Processor: AMD FX-8300 (8 core processor 3.30 GHz)
Memory: DDR3 12 GB
Graphics: AMD Radeon R9 255
storage is 2 TB
windows 8.1 with 64 bit OS x64 based processor.
I just upgraded the power supply from 350w to 420w (will be upgrading it soon to a higher wattage

I think your issue is with your power supply in that it is not supplying the power you need. For your card it is recommended to have a 400 watt power supply and that is minimum. Anytime you game your card is going to need more power.

For your cpu it needs 95 watts sitting idle and when engaged at least 160 watts.

This isn't including the demands of your other hardware. From what I have researched I suggest no less than 550 watts and more may - I say may - be more than you need but I would rather have too much than too little.

Do yourself a favor and buy a good psu such as a Corsair. There are others.
