I recently decided to upgrade my computer big time by purchasing a new motherboard and processor and power supply/case. Anywho, it is a KD7-E motherboard, an AMD Athlon XP processor, and a 300watt power supply. The processor doesn't seem to be the problem though, so that shouldn't be anything to worry about. I put the new MB in to the case and hooked it all up correctly. I triple checked it a million times. It simply would not turn on at all until I hooked a friends power supply in to it, and that seemed to sort of jump start it. It came on, the fans and the lights, and it would seem to go just fine but then it would sort of hiccup and die. We hooked my power supply back in to it and it started working, but hiccuping just like the other. It would start up, fans and all, then they would just die all of a sudden. It seems that it runs longer though if you hold down the power button, for some reason. At first I just thought the power supply or the motherboard was fried, but that cannot be it, since they both work...just not well. I think it might be a short in the motherboard maybe? And it is not a lack of power either. It is a 300 watt power supply and that would be enough I believe. That, and my friends who we hooked in to it was a 450watt power supply, and that is more then enough. Anywho...dunno if anyone has heard of anything like this before, or have any suggestions or tips, but I would really appreciate it. I'd like to get it working instead of having to send it all back to get new stuff, which would be a major pain. Thanks.
