Problems with my power supply?
I just bought a complete new system and I am running -
BIOSTAR TFORCE4U nforce 4 ultra motherboard AMD 64 3500+ cpu eVGA GeForce 6800GS pci-e 1 GB ddr 400 sdram. The problem that I am having is that I had the system running for a couple days and it was working fine. I then started to try and overclock the CPU with the overclocking utility that came with the motherboard which is located in the BIOS. I overclocked the CPU on the lowest setting which brought my processor speed from 2.2 Ghz to 2.5 Ghz. Once I restarted the computer, it seemed to run fine for about 30 min. until it just shut down on it's own and now I can't seem to start it back up. I have a 450 W power supply also. I was also trying to overclock the video card at the same time too. I am just wondering if overclocking the CPU that much higher caused the power supply to short out or did I actually burn out the motherboard or CPU. I also noticed that even though when I press the on/off button, the computer won't turn on, there are still two red LED's that are lit up on the motherboard near the front of the case. I appreciate any help you guys can offer. :crybaby: |

clear the CMOS with the jumper and unplugged

Problems with my power supply?
"JAD" wrote in message ... clear the CMOS with the jumper and unplugged Not a bad idea, but I'm not sure it will help. Even a severely overclocked system should do -something- when the front panel power switch is pressed. There isn't a lot to go on in the OP, but to me, this sounds like a sudden power supply failure. The overclocking attempt may or may not be related to the power supply problem. But if it is a power supply problem, overclocking didn't help any. I'm not sure a typical 450W power supply could handle the OP's rig, whether overclocked or not. I would want to see at least ~26A or better available on the 12V rail(s), if I was building a similar rig. There aren't too many power supplies in the 450W range that could handle that. Not that I've seen anyway. Now granted, the system will probably pull nowhere near 26A continuously, but power supplies aren't rated to run near peak output continuously, either. I suspect (could be wrong) that the power supply was over-taxed as soon as the system was first started up, and that it happened to fail (maybe coincidentally) shortly after he started overclocking. -Dave |

Did you unplug the power cord for at least a minute to reset the overload protection? What are the brand, model number, amp ratings at each voltage, and UL or CSA registration numbers (Exxxxxx or Lxxxxxx)? I ask for the latter in case the brand is unrecognized. It's possible this is not really a 450W supply because your system probably drew no more than 300W, probably less, but many low qualitly supplies can't sustain that, even if rated for 600W. |

Problems with my power supply?
Thanks for the replies. The first thing that I did was to clear the
CMOS and that didn't do anything. I also took the power supply out of the computer, had it unplugged all night and just tried hooking it back up, but it still won't come on. The specs on my power supply are this: Xion power supply model # LC-B450E +3.3V - 28A +5V - 45A +12V - 18A - 12V - 1A - 5VSB - 2.5A E164554 I was also wondering could this have damaged the CPU, memory, or some other component, or won't I find that out until I get a new power supply. |

Deer supplies have been known to cause damage when they fail, but most likely a new supply will restore your computer. Fortron-Source makes very good supplies under several brands, including Sparkle, yet they're also among the cheapest. A 350W Fortron should have no problems running your equipment, and a 400W definitely will have none. |
