i have been having some trouble with a dell Xps 15 laptop that i recently purchased. it is under a month old, and a problem has occurred, upon logging on just after start up, the computer will just sit on a black log on screen (with the mouse still visible and active) for a few minutes. it is extremely annoying, especially when im in a rush. the laptop is under a month old. So far, i have tried to update the drivers, all windows update, and still, nothing. also, it doesnt seem to do it when i log into safe mode, or if it does, it will do it for less than 10 seconds, then load the desktop (in normal boot, it usually takes a few minutes). i have also run a number of the inbuilt diagnostics, but found no errors. i want to avoid having to do a system restore for as long as i can. does anyone know anything that can help? (the laptop is running a 500gb SSD, 2gb Nvidia 640m, 8gb ram, 3rd gen i7 quad core with 8 threads) thanks.
