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?

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
