anyway guys you are the experts i m not really that good. listening to you guys ive learnt a lot

Thank you for your hints.
I have now bought a New Graphics card, but have the same problem. I will be running the diagnostic tonight to see what it comes up with. You mentioned switching off paging (or something), how would I go about doing that?

With the major parts already changed, troubleshooting should move from guessing at hardware to isolating drivers, memory, the motherboard slot, and the OS. The earlier question about "switching off paging" is answered below, but it is only a temporary diagnostic step — disabling the paging file can cause programs to fail if physical RAM is low.

How to disable the paging file (common Windows paths)
Right-click My Computer -> Properties -> Advanced -> Performance -> Settings -> Advanced -> Virtual memory -> Change.
Choose the drive, select "No paging file", click Set, then reboot.
(Under newer Windows builds the same dialog is reached via Control Panel -> System -> Advanced system settings -> Performance -> Settings -> Advanced -> Virtual memory -> Change.)
A safer first move is to set the paging file to "System managed size" rather than removing it entirely.

Prioritized checklist to apply now

  • Boot Safe Mode and do a clean uninstall of the GPU driver, then reinstall the latest WHQL driver from the GPU maker.
  • Run a bootable memory tester (memtest86 or similar) for several passes; swap or test one DIMM at a time.
  • Inspect Event Viewer (System/Application) for driver faults or disk errors that coincide with failures.
  • Reseat the GPU and RAM, try a different slot (or onboard video) and swap cables/monitor.
  • Confirm the BIOS sees the card and consider a BIOS update only if the changelog mentions video/memory fixes.
  • If faults only occur under load, monitor temperatures; if they happen randomly, suspect RAM or motherboard issues.
  • As a last resort, a repair install of Windows isolates driver/OS corruption.

Caution: disabling the page file is a diagnostic step, not a cure. If the diagnostic runs reveal RAM or driver failures, addressing those (replace bad DIMM, clean driver install, or motherboard repair) is the correct fix.

I have now also purchased a 600 watt power supply (which should arrive shortly). Hopefully this will sort it out.
Will keep you posted, but thanks for your help.

I have now installed a new power supply but the problem is still occurring
Any other suggestions?

Thanks
