So i have a Radeon x1600 pro and wanted to put it in my system. I tried putting it in with my current power supply but it didnt have enough power.So i had to replace my old powersupply with a new 500W one. So im having my friend install the the new powersupply and when we hook it in (we had it on top of the computer just in case) and it explodes. We put my old one back in along with my graphics card and it works fine. Normally i would get a no signal screen but now it works fine. But heres the odd part. I did this at my friends house and the plug the new power supply was hooked into when it blew up is the only plug anywhere that will let my video card run without a no signal screen. Im wondering if anybody knows what may have happened and why that wall socket is the only one it will work in. Thanks.
