It can take up to 8 GB of RAM. If you are going to upgrade go for the 8 GB. You can find it on tigerdirect.com or newegg.com and the upgrade is a pretty simple process.

On the cloning I use a program called True Image http://www.acronis.com/homecomputing/pro...-US-EN-SEM-branded-ati&gclid=CN6CrKPA3rQCFao7MgodxzwAAA I use it for customers that have a hard drive going bad and it has the factory restore on the same hard drive. It images the entire drive all partitions. You could use it from your bootcamp side because I do not know if it works on OSX. I know you can use it to resize the partitions as well. However if it was me I would just do a fresh install of everything to have a nice fresh start with a SSD. Side note make make sure you turn off the auto defrag in Windows 7. It will burn up the SSD.
You are going to need a Windows XP disk to reinstall the operating system. Once you have the operating system installed you will need to go to Dell Support http://www.dell.com/support/home/us/en/1... and enter the service tag number that should be on the machine. That will direct you to the drivers which you will need to make all the components work with Windows.
I have had these fail before and it turns out to be the power board in the unit that powers the drive. The drive itself turned out to be fine. I would crack it open pull out the drive and hook it up inside the pc and see if it still works. If it works then just buy a new enclosure.
Last thing I think that you have left is to try a new LCD. They are anywhere from $75.00 - $100.00 depending on where you buy it from. Was the LVDS cable and the inverter board known to be good working parts?
