ASUS-A7M266+ATHLONXP PROBLEM

hi there,
i just bought an asus A7M266 (kt266) and coupled it with an athlonXP 1800+, after flashing the bios (just for it to recognise the 1800XP) my system started up and posted..everything ok except that everytime i raise the fsb to 266 making the athlon run at 11.5x 133= 1533 when windows XP starts it hangs ,and a blue screen pops up saying:
"windows has been shut down to prevent damage to the pc."
??????????????????????????????????????????????
that was my reaction then,
i know it's wierd so i am now running at 200fsb, 11.5x
safe mode if you ask me, what could be wrong?
here is my hardware set-up at a glance:
256 megs of ddr2100, hdd 40ATA100, radeon 8500/or geforce2MX400...
thanks

Check if your PCI bus speed is 1/4 of the FSB at 133 MHz (133/4=33.3 MHz) otherwise you will be running your PCI devices at 44.3 MHz which is way over standard.

My case has so many fans that it hovers above the ground .

oups, sorry about that, it is actually the amd761 chipset, and no i flashed in the right bios, if it was the wrong one, the board wouldn't even started!
and about startup temps, well the cpu is running cool even with the 266fsb...about 45 idle....
could it be the pci clock?sounds logical.
i will check that and get back to you guys.

no actually my PCI multiplier is 1/4........
so i guess the pci's are ok, anyway i have tried removing all of them...but still the same

but shouldn't the shipped drivers work fine with 266fsb?????????????????????????? or is it a windows xp compatibilty/mobo drivers issue?
and you see the problem is that i now can't downgrade to the windows98se unless i format, and that's the last thing i want to do.

i have a question will the a7m266 work with a 1600 xp because thats what i ordered and it was one that new egg sold as a package so as far as i can see they are compatiable but also i figured newegg took them being compatible into account

Hey Guys.
Right now if you order the a7m266 it's bios is 1.05 so it is fully compatiable with amd xp's. I just built my first computer and i had no problems at all with any hardware except for me buying a cheap case that doesn't excatly fit the mobo, wierd. well a7m266 is a great mobo and works at 1400 mhz with the xp 1600 witch is 100% speed. if you use a xp 1600, a7m266, nvida geforce 2, 300 watt pwr supp, lg cdrom, teac floppy, wet dig hd dr it is my experience it goes smoothly. I used a 120 gb hd dr it takes forever to format because it comes to 114 gb. wow does it take forever.
