Missing drivers alienware laptop (M14X r1)

My buddy was trying to clear up some space on his laptop. After he finished, he tried playing his game aaand it crashed. Looked into it and found a bunch of drivers missing.
The graphics card driver is missing, some dell drivers, Alienware drivers, and alot more stuff. I've tried downloading some of them and it wont work, i would give more details but i could only use it for a couple minutes before he had to go. Any suggestions as to what i could do?

 

what graphics card would help, nvidia or ati

system spec cpu/gpu/ram/hard drive

also what did he use to clean it. cc cleaner/register cleaner i guess.

alternatively try a system restore

 

You can try 3DP Chip. It's pretty good about picking up the devices and pointing you to a URL to download the driver (it may not be up to date, though). Windows update also will find some.

 

All the drivers are on the Dell site. Do a search on "m14x initial installation", I think that will find instructions on which drivers and what order to load them.

 

The computer's service tag number should be printed somewhere on the notebook. Failing that, it will be listed in the BIOS (usually accessed by hitting one of the function keys, F2, F10, et al). Enter that ID into Dell's support page, and it will bring up a complete list of available drivers.
