Wow. Sounds to me like there's no really accurate way to test the power supply. Maybe the best bet would be to exhaust all other possibilities and if the problem persists just replace the power supply to see if that fixes it.
Those of us with more than about 2 puters keep spares of stuff like this. Module swapping is the easiest way to troubleshoot. Find out if your Dell uses a standard ATX power supply, then if it does, consider buying one if only for dealing with problems like you have now. I was going to suggest getting one like the last I bought. Newegg has been having $10 off sales on it every weekend for a month at least, but it seems others are finding it a problem: http://www.newegg.com/Product/Product.asp?Item=N82E16817171007 Mine works fine, in an old system that blew 3 power supplies in less than 6 months. -- "The Lord is my strength and my shield; my heart trusts in him, and I am helped."
