i was attempting to fix a problem where my windows kept on tabbing out, and i got to a forum that said to go onto msconfig.exe and turn of all services, and then turn them back on, after a reboot my computer turn on as it normally does, but now no display is shown and my keyboard doesn't light up.

Please help i dont want to take it back into store again, its allready been 8 times this year
