Crashing issues with HD7850 XFire

[Durtyjonny]

I recently built a new computer with 2, 2GB HD7850 in crossfire. I am running into a lot of freezing and lag, occasionally it is as if my display (2 moniters) are resetting.
I have verified all drivers and updates are current, but still the issues persist. The only thing I can think of is the power supply might be insufficient. Currently using corsair 800w silent pro gold. Is it just not beefy enough to handle this set up
Msi Z77A-GD65
Intel i5-3570 CPU @ 3.40GHz
Corsair Vengeance 16GB
Gigabyte HD7850 2GBddr5

Your PSU is sufficient, but its not from Corsair. Its from Cooler Master.

yeah,i agree with JJ1217,you PSU is sufficient(http://www.amd.com/us/products/desktop/graphics/7000/7850/Pages/radeon-7850.aspx#2),try resetting the factory default settings of your monitor with Pstrip and as u said that you are running into a a lot of freezing and lag,try updating your bios and it would be better if you buy a cpu cooler(e.g.Cooler Master Hyper 212 EVO Cooler)and keep updating.

Is it freezing during gaming or just at the desktop?

If during gaming, are you monitoring temperatures for the graphics cards?
