Answers :

I have done countless transplants with over the counter PSUs in Dells, HP and many other OEM rigs without incident. I would suspect you have a faulty PSU. Just make sure you are getting one with a little more power than you currently have and try to match the design spec as much as you can. If you can find one without the aux. power switch then that's even better, but it makes no difference.
