I have recently upgraded my abit bh6 based pc to 950MHz (overclocked 633 celeron2). It ran fine for a couple of weeks but then permanantly blue screened.
I have tried to reinstall windows98 from a clean c:format but I get a Fatal Error message 0D @ 014F:00002B6B just as it finishes installing and before the backdrop appears. I can get into safe mode though. I have never had a problem with a clean '98 install before so I assume I have a hardware problem. I noticed that the graphics sometimes became corrupted when I was playing in safe mode (I running an old Diamond viper v550 riva TNT base graphics card).
I would really appreciate any advice.
Cheers!

Hiya
I don't know about that particular error but you could try looking at

My suggestion is first put the Celeron speed down to 633MHz.Then try booting to windows.This might solve your problem specially if the bus speed was changed along with the multplier.
Running at higher bus speeds can damage your hardware.
Trouble shoot your system with Celeron at 633MHz and not at the overclocked speed.siri

Yes, I thought it might be worth trying de-clocking the CPU. The thing is, it's been running at 100 MHz fsb to clock my celeron 300a to 450 for the last three years without a problem. It seems unlikely that clocking a 633 to 950 by using the same 100 MHz would cause problems. I'll try it anyway - you never know!
Cheers!

Should have been your first step. Overclocking is outside the normal operating range. Can always cause a problem.

I ran into all kinds of errors in a lot of programs including those similar to what you mention. It turned out to be a damaged memory module. This was a Micron memory stick too. So stuff can happen. If you have other memory to try check that out.

Here is some info I had about overclocking which might be of interest:
Will it damage my CPU or other components?
There are a number of things that could happen to your system through overclocking but, with a little common sense, you can remove most of the risk. Heat is the primary concern. The CPU is the system component that is most likely to suffer from excess heat. Higher clock speeds and/or higher voltage create more heat. Extreme heat can literally fry the CPU. Keeping the voltage as close as possible to the default of 2.0 volts and using a quality heatsink and fan will keep the CPU temperature within reasonable limits.
Long term effects of higher current produced by faster clock speeds can have more subtle effects. A process called electro-migration can slowly erode the microscopic circuits inside the CPU--causing the traces to spread and the semi-conductor junctions to break down--until the CPU eventually fails. This is a very slow process and it takes years. A modern CPU has a design life of 10 to 15 years. While the life of your overclocked CPU may be somewhat shortened, do you really expect to be using your current 300 MHz processor, even overclocked to 450 MHz, in even as little as 5 years? By then we'll all be overclocking 1000 MHz (giga-Hz) CPU's.
Since BX motherboards like the BH6 and P2B are designed for a 100 MHz bus speed, you are not likely to hurt the mainboard with speeds up to 100 MHz. The other components, however, can be negatively affected by bus speeds other than the standard speeds of 66 or 100 MHz. At all other speeds the PCI and AGP clocks are higher than normal (see the table below). Besides the obvious effects of increased heat generation, some peripheral devices are especially sensitive to timing problems when the PCI bus is over clocked. Some harddrives will trash your data if the PCI bus is clocked too high .
FSB PCI FSB Ratio AGP FSB Ratio
66 MHz 33 MHz 2 to 1 66 MHz 1 to 1
75 MHz 37.5 MHz 2 to 1 75 MHz 1 to 1
83 MHz 41.5 MHz 2 to 1 83 MHz 1 to 1
100 MHz 33.3 MHz 3 to 1 66 MHz 3 to 2
112 MHz 37.3 MHz 3 to 1 74.6 MHz 3 to 2
124 MHz 41.3 MHz 3 to 1 82.6 MHz 3 to 2
133 MHz 33 MHz 4 to 1 88.6 MHz 3 to 2siri
