I recently switched from a Zebronics G31 board and Pentium D 925 to a period accurate Gigabyte GA-945GCM-S2L board and a 1.80 Ghz Pentium Dual Core for my HCL system with 4 GB RAM and a Zotac GT 730 Zone Edition, but ever since I have had the infamous nv4_disp 0xEA error during certain game launches and in the middle of the same games, I did DDU, reset all possible settings but nothing seemed to fix the issue and going back to the Pentium D stopped the issue. Any ideas why this happened?
