I recently replaced a set of 2x2 DIMMS for one G. Skill 4GB DIMM. I also replaced the PSU to an EVGA 500w and the graphics card to a Radeon 7770GHz (No fanboyage please) and now all of a sudden the computer will either do one of two things: Start as normal which is rare, or release BIOS messages. I have isolated the error code to the Memory. I have reseated and seated the RAM, cycled through all the slots for it, and cleansed the slots and legs multiple times to no avail. I didn't use anything wet, so I don't think moisture has anything to do with the RAM issue. Any suggestions? It's really aggravating me.
