Why does my computer not boot?

I have a Dell Precision Tower 5810 with Windows 7 Professional 64-bit installed.   The option to upgrade to Windows 10 was included.   I downloaded Windows 10 from the Dell website and burned it onto a USB stick.   When I booted to the USB stick, Windows 10 began to  install then the screen went blank.   Now I cannot even get into setup to try to get it to boot.   When I tap F2 on bootup to enter setup or F12 for selective startup, the screen is blank.

Booting from Windows 10,

Without the USB, what happens when powering up?

Usually, an upgrade has to be initiated after the system boots into Windows 7 in your case, then inserting the USB with the media, running the setup that will go through the upgrade process.

Status on system, does it suggest something else might have failed,power supply, bipping for memory, graphics issues.

It seems that your initial attempt may have wiped/altered the HD content, and after the Dell splash screen lacks the ability to boot.

If your system includes an addon graphics card. Pulling it and using the builtin to salvage.... Then if system boots with the builtin graphics, go through upgrade, once upgrade, look at the graphics ........

The install process takes time, the screen saver might have kicked in and was rerouted by your action.......

Also, without the USB,  shut down, start up and press Shift-F8.  Can you boot into Safe Mode?

I cannot even get into setup, never mind safe mode.   I will pull the graphics card then try again with another monitor, in case that is that is the problem.

It well may be the graphics card because some of these are not Creator update compatible. Remove it and that will leave you with at least VGA and see if it starts.

Dell offers a full set of drivers

see:  http://www.dell.com/support/home/us/en/19/product-support/product/precision-t5810-workstation/drivers

So the PC should be able to run Windows 10 64 bit.   However I saw its had nearly 10 Bios updates in the last 18 months, with version A20 updated 27 Sep 2017.    See their note that version A11 is required before going to their target BIOS rev.

remove or disconnect all devices - printers, card readers, usb devices
then try again
windows 10 - like all other windows versions often hangs on (older ) not supported devices

Remove CMOS battery or refer to motherboard's manual to clear CMOS data, then retest.

I removed and replaced the CMOS battery, however that did not help.   I replaced the video card with the one originally shipped with the computer and I can now get into setup.  When I inserted the USB Dell OS Recovery stick and rebooted, the computer booted into Windows 7 normally.   Any idea why?

Replace all the main drivers: BIOS, Chipset and Video - Video for the card you want.
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

This suggests that the replacement video card isn't supported by Windows 10. Also, have you changed from legacy BIOS to UEFI BIOS and enabled support for secure boot? Setting the BIOS options for Windows 10 can be a bit of a minefield; there is a lengthy article here:


... outlining the numerous gotchas awaiting the unwary, and I don't doubt that there are many others.

There is no VGA, just the supplied video card.   After inserting the USB Win 7 OS recovery, the computer booted normally into Windows.   Perhaps that was a coincidence, as it then booted normally without the USB stick.   I just installed all the previous devices and everyone seems to be getting along with each other.   I will stick to Windows 7.

Thanks to everyone for their suggestions.

If the card is compatible with Windows 7 that may be the way for this computer.
