Evesham Axis 1400 WK Computer, Athlon 1400 CPU, 512 Mb PC2100 DDR DIMM, Asus A7A266 Mobo, approx. 4.5 years old.
Now needs several attempts to boot up and when it does goes into the BIOs with the falling message, "During the last boot-up, your system hung for improper CPU Speed setting. Your system is now working in safe mode. To optimize the system performance and reliability, make sure the CPU speed setting conforms to the specification of your CPU". The speed setting in the BIOS is set at 1400. I have spotted an earlier comment in the forum about the CMOS and the battery so fitted a new battery and re-set the BIOS. No improvement. Could it be the CPU and or mobo? If so can you obtain replacements that are compatible?
I have recently had a very similar experience, eventually I had to dump logic and replace components until I fixed it - it turned out to be the mobo even though it had pased every diagnostic test I could throw at it. Have you run any such tests it might be useful to do so - I recommend you use PC Check if you can get hold of it, it's a great utility works off a bootable floppy. If you can't get hold of one I'm happy to "loan" you one if it will help.
Wobblymike I think you are correct, it is a motherboard problem and not a BIOS one. Difficult to get hold of motherboard that is compatable with existing CPU and other items attached to it. Does this mean a new computer? Any help would be appreciated.
Walnut An Athlon 1.4 is not that rare and should work in a range of mobos - I guess its a Socket A (462) CPU - try googling it there are a range of gigabyte or ASUS boards that should do the trick
Failing all that a new mobo and CPU at the same sort of speed as your existing one should be pretty easy to find on e bay at a reasonable cost - e.g I have recently bought a Gigabyte 71Xe4 and 1.1 GHZ AMD processor less than £20 inc postage - it can be done if you are patient.
