Hello,
One month ago i purchased and put together my custom pc.
The specs are:
Motherboard Asus m5a97 plus
processor AMD FX-8350 8 cores 4 ghz
graphics card nvidia geforce 950 strix oc gaming
8 gb ram 1866 hyper x fury
After long hours of playing gta v , dota 2, crysis my pc makes some really loud noise. Eventually it freezes. The only way i can regain control is by restarting. Upon restarting, some weird disturbing noises come from the case. However if i turn it completely off and reboot it tends to go back to normal. What could it be?
 
I once had a system that would do a similar thing (a very very long time ago when I was 12 and didn't know much except how to overclock).. The power supply wires would warm up and droop a power connector onto the fan making horrible noises and causing the system to crash and overheat.. It was all because of poor cable management..
