9nda3J Cold boot problem

[Bob Bartlett]

I am having a strange issue with my Epox 9nda3j mobo with winnie 3000and an Antec Truepower 380 PS.

I have my system set to 9 x265 and I have stress tested it and have no random reboot problems, but whenever I cold boot, either from s3 standby or a regular shutdown the system does not boot up. The fans start, the case lights up and the hd is working is but nothing on the monitor.

I have to switch off the power supply from the back to turn off any power going thru the system, then switch it back to ON, then it boots with no problem but I have an error message that says reset processor in bios. I go into bios and just select save and exit and it boots with no problem.

It only does this if it has been shut off for an extended period usually more than 10 hours. During the day it has no problem recovering if it has been only a few hours. I thought it might be from mu intellimouse on the usb, but I changed it to the ps2 port and it didn't help.

MaKE sure you have disabled both sleep and hibernation modes in Windows. Also replace your CMOS battery or at leats check the voltage on it with a multimeter to see if it is run down. See if that helps.

Sounds like symptoms of bad/leaking/bulging caps, but that can't be (this quickly) I think ...

So, have you tried a more powerful PSU ?

Is ther a later BIOS revision than yours ?
Is there a mention of this problem in the readme from that ?

look here:

or check the FAQ (in the same support pages)

Nothing else found at this moment ...

Well I disabled both standby and hibernation, and I have the latest 2/15 bios. I did a regular shutdown last night not the suspend to ram shutdown and after being shut off for 9.5 hours it started no problem. I did look at the caps and they look fine, let's hope they stay that way.

If what I heared was right, the caps should stay OK.

I had a report from a Serbian member that said that EPOX now only used SANYO caps on their boards ...
Those are a well-known Japanese brand that is reliable.

Have you checked the make of those caps yet ?
Can you tell us what 's printed on their, pls ?

[Bob Bartlett]

Mine are sanyo.

[noorman]

Thanks for that confirmation; there boards will be OK from now on then ...

Might go back to EPOX in future.
