So, I have an AsRock G31M-S R2.0 motherboard ( ,which according to the AsRock webpage supports up to 8 GB of RAM, so I bought a set of 8 GB RAM (Kingston KVR900D2N6/4G),two of these, and when I install them screen stays black, if you say that the memory is not compatible, it is in the compability list ( http://www.asrock.com/mb/memory/G31M-S%20R2.0.pdf ), the other confusing thing is that I am running on an G31 intel chipset ( http://ark.intel.com/products/31913/Intel-82G31-Graphics-and-Memory-Controller ), which on the webpage claims to only supporting 4GB RAM "depending" on the memory type,also I contacted AsRock by email and they said that they tested it with the same memory/CPU (probably lying), I have cleared CMOS a lot of times, I have removed every single component from the motherboard, cleared the CMOS and it doesn't work.I am running on Windows 32-Bit for now but that shouldn't prevent it from booting.I have an Intel E2180 CPU and a nVIDIA GT 210,also in the processor page from intel it says that the base clock is 2.00 GHz, but mine shows 1.80.Please if you have any idea help me,if you need to know something else ask on the comments.Sorry for long post.Link to processor : http://ark.intel.com/products/31733/Intel-Pentium-Processor-E2180-1M-Cache-2_00-GHz-800-MHz-FSB .
