i have come across a problem every time i turn my computer on it goes to the windows screen with the rolling bar and the rolling bar starts to break up and become distorted then once windows loads the screen is unreadable as if it is in a very low resolution i have updated the driver on my graphics card but still seem to be having the same problem i have tried to start in safe mode but am unable to see the screen as the resolution has set itself to very low can anyone help
this is very hard to explain without actually seeing it for yourselves

The distortion you describe (the Windows boot animation breaking up, then an unreadable desktop that looks like very low resolution) most often means the graphics hardware becomes unstable once full video mode or acceleration initializes. The earlier replies from and point in the right direction; below are additional, practical diagnostics and safe next steps that do not just repeat those suggestions.

  • Watch the screen before Windows starts. Enter the BIOS/POST screens (press Del/F2/Esc depending on the PC). If corruption shows up there or during the manufacturer logo, the problem is almost certainly hardware (GPU or its power/cooling). If the BIOS looks fine but artifacts begin at the Windows logo or when the driver loads, the issue is likely driver/OS related.
  • Use Advanced Boot Options (press F8 at boot) and choose "Enable VGA Mode" or "Last Known Good Configuration" to get Windows running with minimal video. If that gives a readable desktop, use System Restore to roll back to a point before the driver update, or uninstall the current display driver once you can see the screen.
  • Boot a small live OS (a Linux live USB or Windows PE) and observe the display. Persistent corruption in a completely different OS points to hardware failure; a clean image there suggests the problem is Windows drivers or configuration.
  • Inspect the card and PC internals (power off first): check the GPU fan/heatsink for seized fan or heavy dust, look for bulging/leaking capacitors on the card or nearby motherboard, and note any burnt smell. If temperatures, fan behavior, or visible damage stand out, the GPU or PSU may need replacement.
  • If you can boot normally at times, use a hardware monitor (HWMonitor/GPU-Z) to check GPU temps and clock stability. Sudden drops, runaway temps, or artifacting under light load are signs of failing GPU hardware.

If hardware is failing, replacement is usually the long-term fix. Always back up important data before doing invasive troubleshooting, and disconnect power and ground yourself before touching components.

Hi,
It sounds like your video card is playing up. Remove the card, plug your monitor directly into your motherboard and see if you have the same problem (Video may be slow), if it is working and you can, change the video card slot, or if you can try it in another friends PC just to ensure that it is the card.

do as Bob suggested, check also your device manager..for any errors in your driver..if you got an extra video cable..the cable that connects from your pc to monitor try to replace it check if it will help :)
