Onboard Lan Port Hangs Computer At Startup , if Disable in Bios pc will work fine

[prspravin]

dear all...

I am from Nagpur MH, Having Trouble , I am Using p4 processor , Intel Chipset i945lm4 Mother Board , The Problem is A Onboard Lan Port Dead (Detect Sometime ) If Lan Enabled In Bios PC Hang at windows startup process , If Disabled Computer Will work Fine , External Card working but some time Automaticly Hanging Computer, So Please Help ! :idea:


here are done
1. I have changed Onboard Lan Port but No success ! ,
2. Flashed Bios but problem still occur

Hello Pravin,

Can I ask under "external card" you mean LAN adapter in some motherboard slot ?

Is there some other cards in motherboard slots, except video card ?

PC hanging is happened only in OS, or there is situations when hangs in BIOS or before OS loading procedure ?


For now I can say to check IRQ addresses of connected hardware, and check installed software, specialy firewall shields,... check all device drivers. Probably there is IRQ conflict.

Try to remove additional cards if present, and try.


I saw many times that situation when integrated LAN make freezing of PC, solution what I use is to disable integrated LAN and use LAN adapter in motherboard slot.



Best regards,
Peter

check the powersupply atx. test with new power unit. remove the cmos battery replace with new one problem not solved then remove lan bga ic on board . use external lan card

hello sir tpetar

thank you for reply
i mean onboard lan (inbuilt in motherboard)
there was a yellow mark on my lan card in device manager, i was not able to do anything,

bios working fine no hanging problem in bios , only hang while windows loading process , some time enable lan card in bios mode xp boot and detect lan card with yellow mark, and suddenly undetect after 2-3 minut


after disable in bios i can boot windows xp fine, but windows 7 wont boot at all no matter lan card disable or enable

thats why installed new lan card (external) working fine , but problem is i cant install windows 7 at all

suggest me to disable lan hardware and how? (disabled in bios not working) i just want install windows7 on it


thanks in advance

What exactly happen when you try to install Win7, how setup is stopped with what error message?

I think you have IRQ conflicts in PC.

What additional cards you have in PC (modem, tv tunner, sound card, USB/RS232/LPT ports cards,...)?

What motherboard you have, exactly model number?

after windows install , hanging while "setup is preparing your computer for first use", :sad:

Additional card Is working fine without additional card same problem happen :/

Chipset : Intel i945G/GZ
MOTHER BOARD NAME: ZX-I945LM4 Ver: 1.5 (made in China) AMIBIOS Motherboard
Video Card : Intel® 82945G Express Chipset Family

Did you try to start and finish installation without any additional cards? (Only clear motherboard, all expansion slots clear).

Yes

triend 5 time , no success , same problem

Try different expansion slot in motherboard. Some motherboards only accepts specific cards in some slots not in all.

If that do not help try this:


Try following step by step in this order of steps:

1. Remove all additional cards from motherboard.
2. In BIOS use "Load default settings" option (do not change any settings except next step).
3. In BIOS disable integrated LAN adapter.
4. Start Win7 setup and install OS (do not put any other cards or software after setup is finished).
5. Add additional LAN adapter in motherboard slot.
6. Install LAN adapter driver.
7. Install other device drivers (VGA, sound, ....)
8. Add additional cards to motherboard.
9. Add additional cards drivers.

Additional to this, there is many cheap and middle class motherboards which cant support to have all slots in parallel work.

tried, same error :'(
i can repair motherboard
what you suggest me about it?
i can change or replace part of mother board, i have same dead motherboard
suggest me to fix hardware (hope you will)

Can You visually inspect motherboard parts, check all parts on physical damage or overheating. Inspect MosFETs, capacitors, diodes, chips, .... look for small cracking, discolored areas, missing parts of part body,... can even looks like as small hole in epoxy of part body.

Check all motherboard voltages on motherboard power connector.


I personally think You have some other problem on motherboard and not with integrated LAN chip.

Usually this motherboard should be replaced, but if you have second the same or similar motherboard with the same chips, why not to try. At least you will increase soldering/desoldering skills. You need hot air rework station with adequate hot air nozzle. For BGA chips you need IR station, if you want to replace chipsets, several times I done that with hot air station without problem.

PC motherboard diagnostics and repairs requires a lots of equipments and serviceman knowledge, from good digital multichannel oscilloscope, logical multichannel analyzers, to IR spot soldering stations and microscopes,... Very often service is based on guessing and huge expirience. Serviceman need to have high expirience and knowledge, he need to know what signal he should receive or send on what point in motherboard, this also requires manufacturers motherboard service documentations. If there is no other solutions for problem, home users usually replace motherboard. Often replacing motherboard even with used is cheaper than service of single BGA chip in some good service.

problem solved ,
done with hot air gun,
i dont know what was the problem,

but its working now

i just hit with 220 digree all parts near lan port and problem solved

thanks to tpeter
