It passed the mem test and the seatool - both long and short, but it would not complete any of the speed test - from safe mode. tried the stress test in normal mode and it powered off very shortly after the test started. I will assume from these results that I have a hardware issue. Is this correct? If so, any guesses as to what?

Thanks again.........

You ran memtest for 6-7 passes in 5 hours?

You might have an issue with your power supply?

Do you know what type you have?

No - will look and let you know. going to buy wife new computer and then fix this one - is the I7 processor functioning properly or should I look at something else? Also, if I need to buy another power supply, what size do you recommend - i.e. how big? 400 W? 500?

Thanks a bunch

power supply is AcBel 300 W. Tried stress test again this morning and again it failed. Shall I assume that the power supply is the issue? software seems to be working correctly, i.e. it seems to stay running unless I get into large calculations, multiple transactions running at once, or large network interactivity. Then it powers off.

Replaced the Power Supply as you suggested and the problem is resolved. Thank you so much for your help. It was appreciated.
