I had 128 Mb PC133MHz RAM on a VIA V845SX Motherboard with a P4 1.7GHz processor and ran XP Pro SP2. I decided to add more RAM and got another RAM of similar configuration but of different company. I put them together and the problem began. My computer started freezing a lot. BSODs on XP saying PAGE_FAULT_IN_NON_PAGED_AREA repeated. I reinstalled XP but in vain. I downloaded Memtest which either showed errors or just hung.........
I tried Memtest on individual RAMs at their respective slots and they do not show errors. They show errors only when they are together. I tried putting them in different slots but in vain. Is there any way to rectify this?? Maybe some motherboard setting or something..............

Remove the already installed RAM module then insert the RAM that is smaller in SIZE or slower in speed in the 1st Slot then the next then so on and so forth !!!
