Windows XP - Blank screen

Users of Windows operating systems such as Windows 7 or Windows XP may encounter a blank screen after logging on. This blank screen issue in Windows XP could potentially be caused by corrupted video drivers. If so, one should download the latest video drivers from the official manufacturer's website and install them while in safe mode. The other option is to inspect the BIOS settings and see the status of PCI bus frequency and PCIe Frequency. The problem with PCI/e bus often arises with overclocking and the user should be aware of these types of issues.


I am using Windows 7 on my laptop. I have been experiencing a Blank/black screen after logging on. I've attempted the below solution:

  • Taskmgr.exe - ordinal not found
  • The ordinal 18 could not be located in the dynamic link library SHELL32.dll
  • ccSvcHst.exe - Application error
  • The exception unknown software exception (0xc06d007e) occured in the application at location 0x76429617.
  • Run DLL
  • There was a problem starting shell32.dll
  • The operating system cannont run %1.


Possible solutions for you:

Solution 1:

  • Head to the manufacturer's site and download the latest drivers for your video card
  • Get to safe mode by hitting F8 upon boot up, uninstall all video card drivers
  • Reboot the computer into safe mode - install fresh video drivers
  • Restart system and let it start Windows normally

Solution 2:

Check your BIOS settings and see if you can lock the PCI bus frequency and set PCIe frequency to "auto".

It sounds like either your video drivers are corrupted or your overclock is over-stressing components on the PCI/e bus. Sometimes an overclock can bring problems even days or weeks after having been without problems.
