Hi. I've got an old Vostro1500 which looks like it came out of the ark. Still it's soild and reliable and so worth retaining. I recently thought I would upgrade my ram to 2 x 2gb sticks - replacing the 2 x 512mb sticks which were installed.
All went well until I came to re-start the laptop. It just won't re-start. I have tried swapping the modules and ensuring they are fully inserted - all OK. I have also tried removing one of the 2gb sticks and replacing with one of the old but serviceable 512mb sticks and the laptop starts.
Any clues as to what could be goig on here? is there a fix or will I end up with 1 x 2gb ram 'ornament'?
