my game is shutting down every 10-15 mins, and I have already tried to reinstall, it didn't work. what can I do to fix this?
Does your PC also reboot ? If YES, then this could be related to your Hardware (GPU Overheating, RAM sticks, MOBO capacitors etc.). But it's hard to jump to any conclusion, as of now.
Do you get any ERROR message when the game closes ? Which Graphics Card are you using ? Just make sure to monitor it's TEMP by using any tool you may have, or use HWMonitor:
What are your System Specs ?? Post a DXDIAG. Does does happen ONLY while playing 'Splinter Cell Conviction' ? Which Power Supply (PSU) are you using, and is it sufficient for your whole PC ?
