What bios are you still on ? All voltages/timings set correctly ? what other hardware is in your PC ?

For the ram run Memtest test 5 for 5 loops and prime or even beter Orthos prime (ram test) for hours , if it doesn't stop there you can exclude the ram. With Orthos you also can test the CPU and or the CPU and ram to test ya overclock or overal stability.

regarding the temps of ya vidcard I think these are normal nothing shocking in fact.

Also try to post in sentences not one text , it's kindda hard to read. Just give us more input and a solution might be around the corner
