AMD ATHLON XP 3000+ upgrade - but Vista won't have it!?!?! I've just upgraded my AMD Athlon XP 2400+ to a 3000+. After loads of not booting BIOS, messing with memory clock speed jumpers, I finally got the BIOS to recognise my processor, but now Windows won't boot, instead it gives me the following: "BlInitializeLibrary failed 0xc000003f". I'm sure all the hardware and the BIOS is good, the Motherboard (V400DBL) is rated for an XP 3000+ with 333MHz memory and the memory's definitely correct now, it just seems to be Windows. If I shift the FSB jumper back to 133MHz everything works fine. I've tried typing the error string into Google and it doesn't appear in any of the results. Can anyone help, or do I really have to run my 3000+ as a 2400 :-( Thanks, Peter.
