computer freeze and overlocking
iftach May-09-00 00:17 AM
1. i've changed my motherboard to abit bh6.
since then my computer freeze when it likes to,
could be when i load windows or when i click
the mouse.
sometimes it works fine for a few hours.

this problem never happened before with my old
motherboard, and no other component was
replaced except the board.

2. i used to put my PII 350 on 112 MHz bus speed.
now with the new abit bh6 it doesn't work any
more. any speed larger then 100 MHz causes the
computer to freeze when loading windows, and
my sound card makes very bad noises.

My comp:
====================
PII 350, abit bh6, 128 Mb sdram 100 MHz,
WD 6 Gb hard drive (master 1)
creative cdrom infra 48(slave 1)
0.8 Gb hard drive as carried drive (master 2)
sb live value, ati expert 8Mb, floppy, isa modem.

Stuttering soundboards are caused by an IRQ conflict. Occasional locking-up can also be caused by an IRQ conflict. Right click My Computer, Select Properties, click Device Manager, look for a driver with an exclamation mark, and run the Windows troubleshooter to fix it. Your ISA MODEM may be set to COM 2, IRQ 3 and may conflicting with the COM2: on the motherboard. That can be disabled in the CMOS Setup. I do not overclock CPU’s and do not recommend it. Larry

Thank you lbyard.

i don't know how to set irq but No problem exist in my device manager.

another thing that i found is that enabling
turbo speed which means 103 MHz instead of 100 MHz
causes the computer to crush at the begining.

as an electrical engineer,when we design a chip,
we clock it 10%-20% faster to check the reliability. if it can't work at 103 MHz , sure it will crush sometimes on 100 MHz.

i tried to take out one component each time,
my sound card, display card, memory, etc.
non of this fixed the problem.

also i found that Norton utilities disk doctor, and speed disk causes the computer to freeze after 1 minute every time they work.

do you think that formating my hard drive and start from the begining can fix the problem ?

thank's again for your help

I would try slowing it down further. If it stops crashing at a slower FSB, I would replace the memory. You may want to try going into the CMOS Setup and enabling OS is PNP aware which will allow Windows to share IRQs. If that sound board is stuttering (for lack of a better word), you do have an IRQ problem, whether or not Windows is aware of it. Usually reformatting a hard disk does not solve problems, but sometimes it does. I do it as a last resort. You may have a bad motherboard, but I have found the BH6 to be an outstanding product. I will not get into an argument about overclocking; I have already learned that lesson the hardway a couple of times over. You are not dealing with just the CPU.

thank you again for your time.

i enabled os in the pnp bios - it didn't changed anything.
i also slow down to 66 MHz but the computer freezes when loading windows.

this is strange cause my friend has the same problem with celeron 266.it is hard to believe both motherboard are defected.

i will try to install windows.

Yes, strange. And both of you bought your boards from the same place, right? A computer fair?... (http://duxcw.com/digest/guides/buymb/intro.htm) Larry
