POST freezes:some times

by DOCSASST Sep 26, 2010 7:46AM PDT

About 3 weeks ago I had the MB moved from one case to
another. After words I was moving data from various HDD (which had OS on them so they were mounted as slave) As a result I was doing frequent reboots. I was doing a reboot when the POST got to the point of simply recognizing that there was a primary slave and just stopped. No matter what I did the system would not respond.. If I rebooted the same thing happened. So I unplugged it and let it sit a couple of days until I got get it to the shop. When I got it to the shop they plugged it in and it worked perfectly.
A couple of weeks later I was again doing frequent reboot when it happened again, except this time POST only go to the point of checking ?NVRAM? when it stopped.
I decided to let it sit unplugged for a day. When I booted it again this time it go to the point of recognizing the primary master and stopped. I let it sit unplugged for another couple of days. Booted it again this time it worked perfectly since then

What are the system temps ?

Have you checked the capacitors ?

How old is the system ?

Plenty of picture of doming, bulging, leaking capacitors on the right hand side of the BAD CAPS home page.

1)No pictures on home page
2)looked at "how to identify" seems to fit
3) but like any intermittent problem there is now way to tell unless it fails. Since last time it hasn't failed

there are PICs of badcaps on the home page ... bottom right of home page.... doming/bulging caps visible but not as prominent as those found under 'how to identify'.

The problem with bad caps is the behavior is erratic and intermittent until ultimately the motherboard stops working.

Good luck.

Just sharing.

I've seen bad caps on any board. Including video, USB cards and more. I know it's a lot to ask but we know to look everywhere.

ALSO, UNPLUG ALL USB THINGS AND RETEST.
