Black screen upon start up on windows 7

Hello, I have a frustrating problem ever since I did windows critical update and changed anti virus and the problem occurred yesterday. Every time I reboot my PC, a black screen appears with a cursor shows up for a few minutes before going onto login screen/welcome screen. I did system restore back to a month and it still doesn't work. I uninstalled anti virus to see if that might be the case and the black screen is still there. I then reformatted my pc by reinstalling windows 7 again using the disc and the problem is still there. My pc is only one year old as well and it's quite fast and quiet. Normally when I startup my PC it goes straight onto the welcome screen/desktop without this black screen. What can I do in this case? Much help will be appreciated.

Could also try loading Hitman Pro or Malwarebytes Chameleon ?

@jaywoo I ran in both safe mode and safe mode with networking ans still no result. However the resolution is different, it comes up big on my screen than booting up the normal way.

@nickf yes I uninstalled using bitdefender uninstall

I still believe it is a graphic card issue. You seem to have tried everything involving software, pointlessly I might add if a reinstall of Windows did not solve it. So now it is time to take the side of the case off and remove the graphics card a reseat it. There are plenty of videos on Youtube showing you how to do it. But it usually involves removing the screw that holds the graphics card to the back of the case, obviously removing the cable first.

Inside the case there will a plastic clip holding the GPU to the slot on your motherboard, this is at the back of the slot. This needs a gentle push or pull whilst pulling out the graphics card. You can replace it by gently pushing it back into the slot. Replace screw and cable. Power on PC.

If problem persists it may mean a replacement graphics card is needed.

By the way when you power on your PC what beeps do you get? These will be a mixture of short/long. Please listen for them and post exact beeps here.

Also make and model of PC would be useful, that way I can have a look at tge manual online.

Ok I will try do that if I can, so you just take the graphic card out and then put it back in again? I don't get a beep when I power the pc on and the PC was customised for me so there is no brand on the case. All I know that I have an Asus motherboard. I will check other components if you like.

Could it be a loading drivers problem? Perhaps it would help if you enabled windows boot logging and read the "ntbootlog.txt" in C drive to see what's loading and what's not Info ClickHere computerfreetips.com and also ClickHere sourcedaddy.com

Download and install this SIW scroll down to the home edition which is free. When you have installed it and opened it you will see on the left hand side about halfway down a list of component headings, clicking on them will open a page on the right. Most of the information will be in the top two boxes. this is where you will find make and model of each component.

If you do not get any beeps then who ever put your PC together did not bother to install the button speaker that comes with a PC case along with the bag of screws ETC which are bundled with the case.
