When I close FSX my computer screen goes blank and my PC locks up. Can anyone tell me why?
What are your system specs and when is the last time you cleaned the dust out of the case fans and heatsink.
Defrag will help also.
Nvida 5200,128 Ram
Fans are cleaned weekly
You need a much better video card, more ram would help but that's not the problem.
It a fair card for FS9 but not FSX.
What video card would you recommend?
Would recommend additonal RAM?
I guess you can use a AGP card but not a PCIe one, your board won't support one.
Check out this thread.
The more ram the faster the scenery will render.
