| 522091 | 2007-02-03 07:23:00 | You say no LEDs come on? do you mean the front panel HDD and Power LEDs? Check you've got them plugged into the right places on the pin header - they might be wrong and causing a short, preventing the system from working (or any other front panel connectors such as audio or USB/Firewire) or if not you could try the whole "remove pc from case, setup and test on bench" for possible random short circuit elimination... |

| 522092 | 2007-02-03 07:37:00 | Does the green LED on the mobo light up?? This is telling u the power is actually getting to the mobo. |

| 522093 | 2007-02-03 10:10:00 | Thanks for asking that question speedy, agent24, pctek, yes . the green motherboard LED does light up and CPU, and GFX card fan spins . but the front panel LED dosent . . I am sure the front panel header is connected properly, as i have tried connecting both ways . Also I have borrowed a 400W Raidmax (18A to +12V)PSU from the office, I plugged it in . But it still has the same stressing result . Fan spinning, no signal to monitor, no beeps, no post . I also tried forcing the motherboard to somehow 'react' to an error i made . ie . . tried booting without any ram installed, but still without any effect . is there any indication that my Asus K8N nForce3 250 is faulty? so how many of you helpful enthusiasts are familiar with this make? |

| 522094 | 2007-02-03 10:19:00 | I would suspect the MB is faulty. | bk T (215) | ||
| 522095 | 2007-02-03 16:51:00 | so how many of you helpful enthusiasts are familiar with this make? I'm not familiar with it but as stated in a previous post, I've got the same mobo but its not running right now. If you were in Auckland/Mt Eden, you could bring it round and I could check it. |

| 522096 | 2007-02-04 03:06:00 | Thanks for the offer speedy, too bad im in christchurch :( So yes, it could be the motherboard that is faulty. I ran the athlon 3200 cpu in my K8V-MX, and it works! that singles out the asus! So how often have you people heard of top quality boards made by Asus, failing?! I examined every sq. Inch of the motherboard, and found no odd cracks, burn marks, broken capacitors, scratches etc.. nor have i smelt any burnt silicon. Im suspecting that the BIOS epprom is blown. any other ideas? |

| 522097 | 2007-02-04 03:25:00 | Another good test is pulling everything except the CPU (including the RAM) out - if the mobo doesn't beep (make sure system speaker is plugged in) then either the CPU or the mobo is faulty. My bet's on the mobo. What makes you suspect the BIOS is faulty? |

| 522098 | 2007-02-04 03:35:00 | I've recently bought a second hand Asus K8N Motherboard and a Athlon64 3200+, .. but there was no POST on the screen. the guy who sold it to me says hes never had any problems with it. Hes upgraded to conroe and dosent need that board and CPU any more. and the board dosent seem to be physically defective in any way. 2nd hand eh! No POSt suggests any tinkering with power supplies, cards, etc, ain't going to do SFA. It's a fair bet that the board or BIOS is dead, which is essentially equate the same thing unless you can replace the EPROM. I think the guy you bought it from speaks with forked tongue. Or he or you have shorted something while disassembling/assembling, which will be very hard to prove which occurred. More likely, but pure speculation, is that he attempted, and failed, to flash the BIOS. Perhaps you'll get lucky if you politely ask for your money back. Ok, yes I agree, that's a silly suggestion. Good luck. |
