hi i recently built a computer with a 250gts graphics card that was overheating so have been runing it without it untill yesterday when i atatched a musashi gpu cooler to it instead of the origional cooler. the computer worked fine for about an hour or two playing ArmA2 with the card never rising above 60c untill suddenly there was a pop and the whole system suddenly shut down and there was a faint burning smell. i unpluged the system untill today and looked at the system and there isnt anything wrong with it at first glance but the system wont turn on or show any sighns of life. the motherboard should always provide power to the usb ports even when the power is off but my wireless mouse and network adapters are off as well as my keyboard. i have tried removing the graphics card which apears and smells fine and replacing the fuse in the power cable but neither of these tings fixed it. does anyone have any idea wheat might have caused this or what the problem is. i think it may have been that i put too much stress on the power sorce and blew that up but that is only a theory
any help will be much apreciated and apologies for spelling and grammer mistakes

plus it was an r-senda, you can get a decent poersupply in the 550-650 watt range from a name brand company for relatively cheap. It's worth the investment to protect your investment. Buy from a known name brand.
try checking out directron, newegg, or even amazon for any of the bigger name brand ones. Seasonic, Pc power and cooling, and several other companies have really good power supplies with 5-7 year warranties.
