PIII errors

I have a PIII 700 that can run up to 933 without problems. Whenever I shut down, the computer goes to a blue screen and freezes, requiring a reboot. At stock clockspeed it doesn't do this, has anyone experienced this before? It's an ASUS CubX board, Radeon and SCSI HD with Adaptec controller and winME. It ran for months at 868 without this happening and started this about a week ago

p.s. It runs flawless at any speed up to 933 with default voltages, just won't shutdown and increasing voltage won't solve it.
 
SCSI is notably sensitive to high FSB. If your mobo doesn't automatically do it, check in the BIOS to make sure you're getting a 1/4 divisor for your PCI slots.
 
no definite answers here but would suggest you try disabling sb emulation & disable fast shutdown (under advanced in msconfig) to see if it makes any difference!
it may be helpful for troubleshooting purposes if you could post the BSOD message in full!
 
There is no BSOD error. The screen just dumps the icons as it would when shutting down and the screen freezes with my desktop background colour but no icons on screen (does this normally when shutting down as well). At 124 my PCI is actually underclocked at 31Mhz and I've used the same SCSI card and HD at 140Mhz FSB without problem on my PIII500. I have SB emulation disables and also have assigned IRQ's in the bios and there are no conflicts with the IRQ's.

I'm stumped!
 
It could be video related. Try changing to standard vga drivers and see if it does it. Even better, throw a PCI graphics card in if you have one. If it shuts down normally, you know it is video related. I had the same problem with my old GF1. At 933 it run stable, but would not shut down/restart, it would hang. After getting a GF2-GTS, the problem was gone. Sounds like a video problem to me. It could be the 89mhz agp and your card.

Yea I think it may be a video card problem too, but I don't have the time or spare video card to play around with it and it's the office computer so I shouldn't even be overclocking it, since it is used for work. I guess it's my nature to push it to it's max, that's what backing up is for 😉. I just can't figure out why it would start to act like this after month's of running fine. It doesn't make much sense, but I guess that's normal in this field.

Thanks for the effort!
