With the battery removed and power supply disconnected, SLOWLY take it apart again and SLOWLY reassemble making sure all the ribbon cables are correctly inserted.

Just buy “paper path cleaner” sheet and use as directed until prints cleanly

In “Advanced Options” click on “Startup Settings” and select “Enable Safemode” and see if it boots up. If it does problem is minor. Try rebooting and if still a problem then use “System Restore” from the “Advanced Options” . Worked on my computer this morning. You can try changing the order above to “System Restore” and if it doesn’t work then “Enable Safemode” and reboot. If it boots to the Desktop O.K then just reboot normally. Good luck.

Go to ifixit page: Nikon D800 Repair and download the manual. Identify your part’s name and then in Google type “Nikon D800, the part name”. You will then see list of web sites that sell the part. Nikon may even have it on their website.

Just upgrade the RAM. It has two slots for up to 16GB.

Try downloading “Ccleaner” or “Advanced System Care” and running to eliminate minor software issues. Majorgeeks is a good, safe download site: https://www.majorgeeks.com/ Have you run Windows Update ?

Hi Brent, You are lucky your AMD CPU is 64bit. 4GB RAM is fine for most basic activities. There are PCI Express ports for graphics card and even a USB 3.0 upgrade, Before doing anything else update the BIOS. I believe 1.08 is the newest: https://www.dell.com/support/home/nz/en/... I’m presuming you downloaded the ISO file for Windows 10 64bit from Microsoft. Don’t use the DELL version - limited drivers, etc. Download Rufus 2.18 last version for Vista and Window2s XP https://rufus.ie/downloads/ Run this with a USB thumb drive in a USB port. MBR Partition Scheme and the USB must be NTFS formatted. Power on and tap F2 at Dell logo. Under “Main” change Legacy Diskette drive A to “None”. Also, change the first boot priority to “USB drive”. Hit F10 to” Save and Exit”. Remember to change the first boot priority back to “hard drive”. I may have left a small step out so be sure to carefully read the screens in the BIOS. Let us know how it goes and don’t hesitate to ask more questions.

Try lifting out and re-seating the card in its slot. Try uninstalling and re-installing the driver for the card. Note: You might try using DDU_Display Driver Uninstaller app to completely remove all traces of old, possibly corrupt driver. If neither helps then replace card.

This is from IFIXIT web site. Read it through. PLEASE HELP! Beeping and black screen when laptop turned on

You need a screw extractor set. They are not very expensive. Make a starter hole with a small drill bit. Then place the extractor tip in the starter hole you drilled. Slowly turn the extractor counterclockwise and press down until you feel the extractor threads bite into the screw head. Turn the extractor slowly to back the screw out enough to grip it with the locking pliers and finish removing . If you are not used to this sort of work “slowly” is the key word here. Don’t rush the job and rest frequently. Watch a few videos on the web if unsure of what you are doing..
