Nvidia Graphics Card: Error 45

G

GeorgeOlphin

My computer worked fantastically. Everything fine, could play most games on medium settings or higher at 1080p with no glitches, dropped frames or artefacts.


So about two weeks ago I fired up my computer (it had been off for a day or two) and I get no display output at all from the motherboard. The fans spin up but nothing coming out of the screen. From this point onwards I have not been able to get any graphics to display from my computer.


I can use on board graphics but the PCIe device is not recognised by 1. bios, 2. device manager (shows error 45) and 3. Nvidia


My Computer:


Intel DQ57TM

Intel i5-650/i7-870

8Gb Crucial Ballistix 1600mhz

300w PSU

EVGA Nvidia GTX 1050 Ti /Zotac Nvidia GTX 1650 (Both cards do not need a 6-pin power lead)

Windows 10 most recent update.


Things I have tried:


1. Physically cleaning the pcie slot and checking for dust or bent pins



2.Changing the graphics adaptor in the bios from Auto to PCIexpress (PEG)


3. Using DDU to disable and uninstall Nvidia control panel and GeForce experience then reinstall Nvidia and geforce experience (with wifi on and with all network adapters disabled and the drivers offline) I get an error saying it cannot detect an Nvidia graphics card.

4. Checked that the computer isn't starting in "safe mode" using msconfig


5. Ran a CHKDSK to ensure there isn't an issue with the drives


6. Using command prompt "bcdedit" disabled pciexpress and then tested (then reverted back to system defaults)


6.1 Cleared CMOS and reset Bios on the motherboard


7. Reinstalled windows from USB using [shift+f10] and Diskpart tool to format drive and clean them.


8. Installed another DQ57TM motherboard (incase it was the Pcie slot) - The device worked for an hour or so until the computer did a windows update.


8.1 Tested all of the above again on the new motherboard.


9. Rolled back the windows update. (no change)


10. Tested using another CPU (i7-870 don't have inbuilt graphics) to try and force the computer into using the GPU - Didn't work just got the diagnostic beep for no video card


11. Tested another GPU (GTX 1650) no change.


12. Rinsed and repeated most of these tests but to no avail.


I am getting really fed up with this problem to be honest. I cannot get my head around why something would work perfectly two weeks ago and then just stop. I personally feel that an update caused this problem but that doesn't make much sense when I have uninstalled all the possible updates and wiped the computers back to basics.
