mb working and not working!!
Hello, I recently stepped into this problem with my custom built system.
First my config. mobo: WinFast K7NCR18D-Pro Processor: AMD Athlon XP 2100+ Memory: 3 Kingston 256MB PC2100 266MHz 32x64 DDR 184Pin Videocard: maddog predator MX 440 8X GeForce4 HD: 4 maxtor 160 8MB Power: Kingwing 350W OS: Multyboot WIndows 2000pro and Mandrake Linux 9 The problem: The system has been working perfectly for little more than a year, I only had to replace a faulty PSU long time ago. About 3 weeks ago when pushing the power button I didnt hear the bip that usually is followed by the bios screen and the OS boot up. Holding the power button for 5 second restarted the machine, bootup fine either on windows or linux. Few days later the same problem became more relevant, I had to restart about 4/5 time befor the bip came along and the bios screen. To make it shorter now the behavior is even worse. Powe button pushed, fans workin, no hd activity nothing on screen, traying again for aout 20 30 times I get lucky and I see the cdrom light blinking and the bios bips and the welcome screen, windows starts booting up, here I have to scenarios, the first windows bootup screen the black with the white progress bar, at soon as the progress reaches the end I get back screen and only the fans are working, I have to restart again, if the progress bar can reach the end the next windows screens appear and with the blue progress bar reaching the end again everything goes balck, restart (well I have to restart dozen of time to get to the windows bootup again) and if a get lucky and widnows passes the firts 2 booting screens everything works fine until the next reboot. What I did to find the culprit: Unplugged everything, only mobo and processor, no results Unplugged only the HDs, again nothing Unplugged video card, memory, cd rom and whatever is unpluggable in many different order...nothing, still same problem. I changed the battery and cleared the cmos, nothign again. Every cables seems to be well plugged and just in case I disassabled the entire system and rebuilt it again cleaning dust and ect. No luck. Any idea or just a stop to a computer store and buy a new mobo? Thanks in advanced |

Any idea or just a stop to a computer store and buy a new mobo? Thanks in advanced Since the board does intermittently POST and boot to windows, the bios is intact. You might examine the board for failed capacitors and reset all cards, cables, memory, etc. Otherwise (even though it seems to be suspect all too often) I question the power supply, because Kingwin makes junk PSU. Their 450W is poor compared to some 300W, and I'd imagine their 350W is worse than many 250W. You might disconnect it from AC for a few minutes and examine the interior, particularly the capacitors where the wiring harness exits... often on marginal capacity PSU those caps give out after a few weeks to months. You might also try underclocking, 100MHz FSB & Memory, and possibly a slight CPU voltage reduction too, to see if that helps any. Take voltage readings with a multimeter if possible but failing PSU caps may not be revealed with voltage readings. |

I checked the PSU and seems to be ok, actually I'm sure because I swapped it
with another one fro a different pc and is working fine, the other PSU from the other pc didn't solved the probem, so definitely seems to be a mobo problem, I cannot see any visual problem or deterioration on the mb, I guess it's time for an upgrade. Oh well, I should start shopping around. Thanks guys |

I think I found the problem.
As I stated on my first post, the ram config was: Memory: 3 Kingston 256MB PC2100 266MHz 32x64 DDR 184Pin But I was wrong. After disassebmling everything I was packing the ram into antistatic bags, my attention dropped on a module saying DDR333!!! I checked and found that I had 2 PC2700 DDR333 and one PC2100 DDR266. I don't know how that happend because when I built the system, almost a year ago I was sure I had 3 DDR333 and I tought was wierd when posting that I got 3 PC2100, but I guess my nephew, that is always around my pc, did a ram swap!!! Somebody is gonna cry!!! ahah just kidding. But anyway, I suppose that the memory module messed up the mobo, even after removing it seems unrecoverable. Is that right? |

No, installing PC2100 along with PC2700 (that variable alone) cannot damage a motherboard. |
