I have an odd problem. Whenever my HTPC is left on over night the image starts to crackle. I originally suspected my HDMI lead, but noticed that if I change the resolution and change it back, the problem goes away.
- 512MB XFX HD 5450
- 3 530 2.93Ghz
- Asus P7H55
- 4gb RAM
Any idea what the issue might be?
