Blank screen + cursor after instelling new graphics card / Windows 10

Hello,

I have been experiencing problems with Windows 10 ever since I've installed a new graphics card: the MSI Nvidia GeForce GTX 750 Ti. It worked well the very first time. But rebooting gives me a blank screen. I have been able to enter the system once (by clicking the spacebar and entering my password blindly but that does not seem to work anymore) to try and update the driver that came with it. I wasn't able to as I first needed to uninstall the previous one, which required a reboot. I was also able to check under Device Manager / Display Adapters to disable the shared Intel Monitor and enable the GeForce card. As confirming these new settings also required a reboot, I decided rebooting was probably the best option. I should have known better. I'm back to my blank screen and nothing seems to work. I have tried F2, F8, F10, F12, Windows + P + down arrow twice, spacebar, and Ctrl.

Would any of you know how to reboot and enter the system? And what to do next?

Thank you.

Possibility the card is faulty. Try reseating the card again and the 6pin Power connector. What Wattage PSU ? Do you get the Manufacturer's logo screen at boot ? What are you using to the monitor HDMI, DVI ? Check that also by swapping cables.

The card did not come with a Power connector slot. I'm not sure about the Wattage - where can I find that piece of information. I can see the HP logo when I reboot, just before it goes to blank. Not MSI (graphics card) though. I'm using the traditional monitor cable, not sure whether I can swop?
After trying many times, I have now been able to boot pressing Esc while rebooting until I got to the blank screen with the cursor. I pressed spacebar and entered my password to a blank screen. So the PC is running now with the graphics card but I'm not sure what to do and I fear that it might go to blank again if I switch it off for the night and restant in the morning.

I hope that you can give me some useful tips as I'm not very techsavvy myself (as you might have guessed).
Thank you.

O.k. said was an MSI card or not, although does not matter it is a NVIDIA Chipset in it, so drivers would be from NVIDIA. Many models of this HP P6 2000 can you give the exact model, i believe may have a 300W Power supply. This card has other monitor connectors on it,HDMI,DVI. Like to check the specs on this model if you can provide exact one. When you buy a Video card need to make sure your system is compatible with it and supplies enough power and has the right PCI-E connection. Card did show it had a power connection on it, 6 pin connection to the power supply.

Do not need to disable other integrated graphics if this system had it, will do this when you connect another card.
Wondering if we can get into Safe mode to check to.

These are the systems specs of video card and pc:
MSI GeForce GTX 750 Ti 2GB OC - Specificaties - Tweakers
HP Pavilion p6-2000be Desktop PC Product Specifications | HP® Customer Support

I have also found 300 W.
So the card looks compatible to me, but it might not be with Windows 10?
I checked the Device Manager: it says the card works well. I have also updated the driver in the Device Manager panel. Obviously, it wants me to reboot now (not sure whether that is such a good idea...)
Thanks for now!

300W is a minimum for this card, this card is a PCI-E 3.0 x 16 but is backwards compatible with your PC connector.
I truthfully would not update the driver through windows update, choose correct Operating system bit 32 or 64 bit here and download it. Driver version is 361.43

Chances can be a driver issue. Since already did it through Device manager it will change once you shutdown or reboot.
Can try to uninstall it in device manager and use generic windows drivers and may work, then download this one and install it.
Choose custom install from software driver ans select perform a clean install.


Other thoughts were you able to get into safe mode and do it there to and to see how it works there to.

Thank you, CountMike. I will try that. Is it important to do it in safe mode only?
And do I then install the new driver in safe mode as well?

This is an update of my progress so far.
I have managed to go into safe mode (once), uninstall all NVidia driver remnants using Display Driver Uninstaller and reinstall Driver 361.43. Once I get past the hurdle of booting the system, everything works fine using the new graphics card.
Booting is still an issue. I seem to be able to manage to trick my pc each time by pressing Esc before I boot, holding it down until I get to the blank screen + cursor, then pressing the space bar and entering my password. So I was wondering whether this might be a problem of boot order. However, I haven't managed to get into the Bios. I have tried a number of key combinations including shift+switch off and F2 or F10 when rebooting, but to no avail. If anyone has any suggestions about how to get into the BIOS on an HP P6-2000be computer, so that I can try to find an option to either disable the integrated GPU or change boot order, they would be more than welcome.
As an alternative option, I was wondering whether there are any counterindications for doing what I do now (= tricking the system to start up)?
Thanks for your help.
