Toshiba laptop screen wont turn on, led's working

[Leposiedon]

Hi, im a realtive novice when it comes to conputers, i usually just use my laptop to run a few client games and some steam applications, nothing heavy. After attempting to alt tab out of a full screen application, my laptop seemingly crashed. After rebooting the laptop the led power indicator turned on, the fan was audibly running, but the screen displayed nothing. I tried connecting it to a separate monitor like my friend told me through an hdmi cable but that did not work, as the monitor read no signal. I pressed Fn and F5 afterwards and that turned on the screen on both the laptop and the seperate monitor, and it worked fine, but when i logged on to windows (10, not updated in maybe a month and a half) the screen went white. I could alt tab and my previous windows i had open showed up, but when scrolling though it would not shift to any of the windows. From there i force shutdown my laptop and now its back at square one. Any help?

Do you see the boot screens or can you enter and see the BIOS?

If you don't see any output, I'd suspect a hardware fault. If you see the boot splash screens and the BIOS, then it's a Windows video driver issue.

Nothing shows up, so no output what so ever in the main screen or external. If it is a hardware fault, do you think i could get it fixed? I know most laptops have internal pieces that dont really get replaced all that easily so im prepared for the possibility that i would need to get a new computer. And if so, would i be able to get my files off of the old one?

No, at least not cost effectively. Most all hardware within a laptop is part of the mainboard/motherboard. So to fix most anything, it means replacing the motherboard. In most instances, unless it's under warranty, it's more cost effective and/or cheaper, to simply replace the laptop.

As to your files, that's easy. Simply remove the HDD from the old laptop, and install it into the new computer as a secondary drive, or connect it to the new computer using a USB adapter or external enclosure.
