Hi everyone, I need help.  I bought a Dell Studio 1535 off ebay.  It doesn't work right.  I get error messages all the time, some of the programs don't work and it runs really slow.  I contacted Dell for help.  They accessed my system and told me that I am missing a bunch of stuff and that it would be best to reformat the laptop but I didn't get the disks with the computer.  They then told me that they couldn't give me the disks to do that because the computer isn't in my name.  I tried to look up how to reformat it back the the factory settings and I can't figure out how to do it.  One said to press F3 while it is rebooting then select restore to factory settings but it didn't have the option or one like it.  The other one said to hit Ctrl and F11 at the same time then click on restore.  When I did that it just started like normal.  I'm not sure what else to do.  Can anyone help so I'm not stuck with a really expensive paper weight?
