Hi guys, I have a problem with RAM.
I have 4GB RAM but Windows Vista recognise only 2.5.
Do you know any solution?
Except changing to 64bit OS.

Hi there, Vista 32-bit can only use up to 3.5 GB. Not more. But still you miss 1 Gb if you really mean 2.5. Be aware that you graphics may also use shared memory!

Best regards,

could be the motherboard? Might not support 4gb

Has your pc EVER recognised all of the RAM?

Try doing 'Clear NV RAM' and 'Load Defaults' in the system BIOS, that might help.
