I don't know if it's the heat but I can't get my head around this!
Fixing a computer for a friend his motherboard was going! Computer would get to verifying dmi pool data and then a weird lines and colour so screen!
So I bought a new mobo and fitted it today and only put the essentials in, once I saw that it booted I turned it off and put the rest of his hardware back in the case, but then it wouldn't even turn on but mouse led is lit up so not a blown fuse, I have reverted back to the original setup that managed to make it boot previously however that won't even work now! I've tried different power supplies and even the old motherboard but I get nothing just wondered what you guys thought!
