hi,

Recently I upgraded the memory of my laptop. It works fine, but after one hour or something, it goes into safe mode and says:Windows xp detected device error and fixed it. save all your work and reboot.

When I reboot it goes back to normal. What is the problem??

thank you

Describe this 'safe mode' a bit more ... does the computer turn off and reset in a safe mode state? Do you have to initiate the restart. The more details you can provide, the easier it is for me to help you out.
