its connected to my M2-atx power supply so i didnt think i would need to use the filter. It only happens when on hot days tho. work fine in the morning or on a cold day. The PC is located in the boot. Would the length of the cables have anything to do with it? voltage drop?
I have a m2-atx in my trunk and run a barrel plug from it all the way to the front of my car to the lilliput 8inch screen with no voltage issue, length is not the issue.
