Cpu good or bad?
New build....
My cpu fan starts as soon as I plug in power supply to computer. I understand this could point to shorted board,but since my cpu fan is spinning,can I assume my processor is good? Motherboard has power,but no boot?

I'm experiencing a very similar problem and do not know why. Sometimes my system starts without shorting the pins, sometimes it doesn't. I seem to be having BIOS trouble.

Try this:
http://forum.pcmech.com/showthread.php?t=132409 That'll eliminate (or point to) a short as being the problem. The CPU is probably is fine (unless you damaged a pin or something), but a running fan isn't necessarily indicative of a working processor (or any other part). Also, list your system specs including the power supply brand/model.

I used it with my other computer,so I know it works. I thought it was probably my board. You get what you pay for. Thanks |

It is still possible the power supply is not putting out enough juice to boot the system. The motherboard could also be faulty. But I would say the easiest thing to check is the power supply. Either hook up the Xion to another system, or find a good PSU from a friend and try it. Then you'll know if its a dud or not.

I think I will try my best PSU with the board,just to make sure. One never knows. I only used this PSU with my Pentium 3, so even though it was fine there,it be having issues with my Celeron. Can't hurt to try. I'll get back with results,later. |

No power! Board is fine. It was the PSU I assumed,since the PSU worked before,and the fan was spinning,all was well. Like you guys always say. First,and most importantly,never assume your PSU is good. Check,double check,and affirm. Thanks a lot Man! |

Is this "ET" or what. I am presently using this same Xion PSU on this computer. It is working fine. I was about to trash it,but I hooked it up again,and its running fine,with this system... 1.0 Athlon,Gigabyte Motherboard,etc,etc. Strange things are happening here man! I took the other 300 Watt PSU,and installed it on my new build P4 Celeron,ECS 648-FX Board,and it is running,but I have to short the power led to start. Must be a bad power button. It doesn't have the additional 6 prong power plug,but I can still short the PSU! CPU fan spinning,CD getting power,etc,etc. I havent' installed any memory,or hard drive yet,just wanted to see if I could get it going without the additional power plug. I wonder if I could boot this board without the additional plug,without doing any damage! |
