New PC won't boot and no post beep
Hi,
I've bought a new pc yesterday (AMD 2400 +, 512 Mb RAM, 64Mb AGP) i build. Before to put HDD and DVD, i would test the motherboard with memory, cpu and AGP graphic card, monitor and keyboard. When i turned on the computer, only the cpu fan turned during 5 secondes and then the computer stops. There was no beep, nothing appeared on the screen. I verified all the connection at least 2000 times. I removed the memory and then i've heard a long beep but the computer still stopped. I replaced the memeory and removed the graphic card, nothing. Removed and replaced the cpu fan and processor. This is not the first time i build a PC. I've got problem with HDD, Graphic card, unplugged cable... But never this problem. I don't know what to do or what to test. So please can you help me ? Thanx in advance Stef |

Try it without anything and see if you can get the fans
to run. Then add parts one at a time. "stef" wrote in message ... Yes i did that in this order. Stef "Rotary Phone" a écrit dans le message de news: gers.com... Sorry for asking but you are sure you completely cleared the CMOS? Sometimes you have to wait ten minutes and make sure the power is unplugged from the wall outlet.

at Tue, 08 Jul 2003 12:17:20 GMT: So please can you help me ? If fans are not even turning then I would suspect either the power supply has gone or something is shorting the +12V to ground, like a plug or part of a board touching metal. Inspect the plugs, cable and clearances. -- mark |

Is the cpu fan connected some m/b won't boot with the cpu fan disconnected?
AGP card correctly seated? Good memory and seated? If you have a PCI video card try that instead of the AGP. Switch memory positions or use only one stick. Pls post details about your m/b, memory and video card. "stef" wrote in message ... Yes i did that in this order. Stef "Rotary Phone" a écrit dans le message de news: gers.com...
