PC gets black screen after Windows logo
PC boots up to Windows logo splash screen but then screen goes black (no cursor). I have tried to boot in safe mode and it stops when it gets to krbt file. Things I have already done for troubleshooting:
Pulled drive out and put in another PC and ran scans. Malwarebytes, Adware, and AVG all came up clean.
Video is integrated so I put a new video card in and same black screen.
Tried new memory.
Tried different memory slots with new memory.
Tried new power supply.
Changed bios battery.
Tried new hard drive and when installing Windows it got to checking for current operating systems and would not go any farther.
Checked CPU and heatsink and heatsink came off easily so I added more thermal paste.
After booting the PC again in normal mode it went to the splash screen and went black. I can hear the hard drive running and the fans are running just no video with a black screen.
I am thinking it is probably a bad CPU or motherboard at this point??? Any and all help is much appreciated!

Any beeps on startup?
its probably from the CPU
It sounds like the hard drive. With the original hard drive, boot the computer with the XP install CD to the repair console. At the command prompt enter chkdsk /r
If it completes, try restarting the computer and post the results.

If your computer had an onboard video, and a pci video card added for a dual monitor setup, there may be a conflict, keep on reading for your solution.
1. Try plugged the monitor to the other video card. It's possible the somehow the video signal defaulted to the added video card, but only after windows booted up.
2. Alternatively, go in to the bios by continuously pressing either f12, f10 ,f9 or del (depending on which system you have ) as soon as the computer powers-on, browse through the screens for an option called "enable onboard vga, and uncheck it. save the new settings and reboot.
3. If you have a Dell computer. Dell's bios offers no option to disable the onboard video card so just set it to auto if it is not already there. To do this just make sure your monitor is plugged into whichever video output that lets you see the boot screens and press (F2 on most Dell systems) to enter setup. Once in setup scroll until you see the video adapter options and set to auto.
Now, cold boot the system. Switch the monitor cable back to the onboard card and restart. You may not see anything until Windows loads (the opposite problem as when using the new card). Once you can log onto Windows do so and at the desktop right click the mouse on the wallpaper (background) which will bring up the display settings box. (Ensure you have the proper drivers installed for the new video card and that the video card is showing up in the device manager [ right click on "my computer" then click "manage" then click on "device manager" in the left column. In the right column expand the "display adapters" by clicking on the "+" sign ] if the card shows with no error icons on it then you are good so far. Once you have the display settings open click on the "settings" tab at the top. You should see two squares with numbers "1" and "2" in them. This means that Windows "thinks" you have two monitors and there is your conflict!!

what was the last installation you did which involved using a I/O device (hardware)
restore your OS to time earlier that .
If you are getting the first screen, it is not related to video card.
Just try the last good known configuration, the earliest restore point.

to do chkdsk we will need to see a prompt or desktop, in this case, it is not available, so in my humble opinion last good known configuration is the first option or an earlier restore point.

There is a virus which causes the black screen upon Windows boot. A friend's machine had it and it was extremely difficult to remove. Unfortunately, I can't remember the name of the virus, but I do remember that I used every virus checker I could (with the infected hard drive connected to another computer via USB) and most either reported that the drive was clean or were unable to remove it. One recent link that I found on the problem is http://answers.yahoo.com/question/index?qid=20100126215449AAIUfYD. I know that you can find other discussions of the virus by googeling "windows black screen on boot". Good luck!
Lets rule out if it is a Windows issue or a hardware issue.
Boot with a live linux CD---
I guess, u know that Linux CDs are Live meaning you don't need to install linux on the HardDisk to get an idea of it. Only the booting process will be slow.
It is very much unlike Windows, Most people shy away from the proposed idea because they think that they will waste an hour or two installing the OS.
Just download the Image, burn it to a CD and you will be able to boot & experience it straight-away,
