so most likely the error occurs every 80+ secs up.
My pc setup:
Windows 7 Ultimate 64-bit SP1
Intel i7 950 Quad Core
Corsair Professional Series™ Gold AX1200
GTX 680 jetstream 4gb
120gb ssd OCZ Vertex 3 for my os and apps
1tb HDD for my documents
12GB Gskill Ripjaws f3-12800cl9t-12gbrl Ram
Heres a little history, i have this problem too when i have the gtx 580 direct cuii and when i upgraded to phantom gtx580 3gb its still there when i downgraded to geforce 210 the problem is still there and now i have jetstream gtx 680.
I am pretty sure i have all the latest drivers, even BIOS, got the drivers from their official sites.
Also when i render the video on premier pro the problem is the same but on windows movie maker no problem at all.
I am thinking that it might be my RAM or something because my motherboard is just 2 months old. :(
If its SSD its 5 months old. So guys pls need help.
