Sometimes you find the BIOS must be current to support the memory sticks.
I recently was "gifted" an Inspiron 9200 and tried to upgrade memory to 2G (said to be max for this unit). But once installed, it will not boot past the black screen with Windows 7 logo. I've already checked that memory sticks are correct and both working individually. I also reloaded/updated BIOS. With both 1G sticks, the F2 screen says memory is 2048MB.(?) Specs: Pentium M 1.60GHz, 32 bit, Windows 7 + SP1,
The computer will run with just one memory stick installed, although the cursor keeps showing the "spinning wheel" as if something as in process.
How can I get this to work with (2) 1G Memory Cards?
