Hi, My computer is have 256 MB DRAM. And it was working fine, i just brought another 256 MB of DRAM. Now my computer hangs with blue screen or display go vibrating (keyboard caps lock won't respond). One time i got PAGE-FAULT-IN-NONPAGED-AREA, but errors are different at different time, some times blue screan death, some times display goes vibrating. I have removed the new RAM, computer is working fine, i removed old RAM and put the new one, still computer working fine. When i add both RAMS, it start hanging. How do i fix the problem ? Regards, Yujin

What are the specs of the two RAMs: Manufacturer, speed, latency? (Part # would help too.) Sometimes the RAM won't work because the chips are too different.
