Eyetech should post a warning sticker on that stupid fan I have seen more than a few users and a dealer who took the fan off the proper shipped position and stuck it in the wrong position. The fan in the proper position is offset to the front of the mother board. People see this and assume the fan is on wrong and "correct it". The fan is reverse polarity protected and won't spin backward. I have seen fans become fused when they where left in that position for too long.
WARNING!!!! if you replace the CPU fan or you use the case fan header. Cut the yellow wire that is on some fans. The yellow wire is a rpm sensor. If you hook that to the AmigaOne you will be putting noise on the 3volt bus.
Kinston SDRAM while recommended is no GUARANTEE THAT THE RAM IS GOOD.
Kinston SDRAM even the same model number vary greatly from batch to batch.
Odd behavior and random crashes or errors ARE ALMOST ALWAYS BAD RAM.....
Your problem is the Memory. The Amigaone Needs memory in order to run the X86 emulator so it can boot the Video card.
To the individual having to reset the machine for the graphics card to work. I have seen this before. Guess what! That too was fixed with the substitution of proper memory modules
Not to do a plug for myself But.... That is why we are buying Memory MADE FOR THE AMIGAONE/PEGASOS boards because of the inconsistencies with memory modules you buy you can never be sure if the memory you buy works correctly. These Modules have been made by the Manufacturer to work specifically for the AmigaOne and have a special model number. MHC-(XXXX)-R1XE. they even put together special 2 Gig packages for the AmigaOne.
One more warning for the DIYr's out there. BE SAFE ALWAYS UNPLUG THE POWER SUPPLY FROM THE WALL BEFORE WORKING ON YOUR MACHINE. We need you and your machine in one piece.
