So, i built my first computer yesterday with the help of my friend who has an IT degree, we made sure we were grounded and everything went great, i got windows onto the new system and played a few games of counter strike during the day and everything was working beautifully, everything was running quietly and smoothly. Then while The Elder Scrolls Online was downloading, my computer froze and i could do nothing, no keyboard mouse, picture was still being displayed but nothing was happening, tried pressing the restart button, didn't work so i left it for 5 minutes, still nothing, so i held in the power on button for a few seconds until the computer shut down completely. after that, my two LED fans wouldn't turn on when i rebooted the system, GPU's fans are spinning really fast, (the sound is very noticeable) and the cpu fan is spinning, nothing would come onto either of my screens so i left it for about 30 minutes and when i returned, nothing, i powered off the system, turned off psu removed socket from wall, plugged it all back in after about 5 minutes, the only thing that has changed now when i boot it up is that by LED's turn on, GPU still going crazy and cpu not much better!. Help me please, i purchased this computer to animate on so i could complete my assignments :(

i5 6600

16gb g.skill ram (ripjaws)
