Picked up a palit gtx 970 today, got home pulled my evga gtx 670 out and put the 970 in and nothing! 
The fan spins and it seems to get slightly warm but it wont send a signal to the monitor.
Pulled the 970 out and put the 670 back and everything worked perfectly.
Any suggestions? or is it return for refund?
Thanks
Stu
