I have a mother board with pentium MMX 233 MHz with 64 Mb RAM.
In the beginning it was not booting at all.Then I increased the 5 volts supply up to 5.27 from the SMPS and it started booting.But it started rebooting when I get a message of "starting ROM DOS".In short booting goes smooth up to that level and then rebooting starts and so on.And this problem also fixes when I raise the supply to 5.5 and it will last for two -three months.At that time you have to adjust voltage again.The question is why it takes 5.5 when it is designed to work on 5.0 volts.Where can the problem lie?Is it a hardware or a software problem? prash email removed. |

I dunno mate,perhaps the power supply is getting too old and not maintaining voltage.

Agreed, for a PC this old it really isn't economical to fix. :)

Dear friends this mother board is not from a PC. it is in a controller of a CNC ( computer numeric control) machine used in sheet metal industry.IT IS EXTRAORDINARILY ECONOMIC IF IT GETS FIXED. though I am not sure that it is because of +5volts; or it just seems so.But it is sure that changing volts(+5) fixes the problem.PLEASE THINK OVER AGAIN AND HELP.SORRY FOR NOT MENTIONING THIS EARLIER. THANKS. Prashsar

Well I did also mention the PSU.Its possible that there is vdroop.That would explain why adding extra voltage helps stability.
