Drama about old GA-7N400Pro2-Dying/dead capacitors-BE AWARE
« on: August 18, 2018, 03:10:40 pm »
All of a sudden at almost the same my two old MOBOs failed working. GA-7N400Pro2(first one older than following)- Asrock Alive Dual eSata2. Both are universal ones with Sata/IDE and Raid. They have always been installed outside cases.
Yes had cooling problem with GA. still processor could be better cooled from outside. had it on a frame to get space to surface to add large cooler from below.
Since its a very complicated story i will lead you to the detailed threads in Sysopt. com forum
All i can say, after almost 6 weeks i could make both running again and Ga-7N400 Pro 2 even allowes me shutting down PSU by turning switch off. Must be tested if i can also remove cable.
At the end one could say among other problems mainly with halve-defective PSU(Asrock) on both MOBOs halfdefective or totally nonworking capacitors are the reasons for sudden deaths. both pcs had been working excessively since i had. Ga since 2004 if i dont err. Asrock maybe 10 years-
When changing drives(be it HDD-ide to Sata) i always had to clear cmos/battery-removal Now at GA... i could form capacitor(s) to be able shutting down PSU(SWITCH OFF). on Asrock i still have to enter cmos-data.
Since i have multiples of both MOBOs I will setup later a second Asrock with replaced capacitors.

on GA i have also a Sata-boot-problem. its very complicate-pls read.
but its related also to a bad Bios see here:

Some also replaced a newly programmed BIOS-chip!

Newest SIL(Silicon Image)-drivers were wisely deposited here:
SORRY it seam wrong link in Sysopt-tread will check if i can find. but i downloaded data.
I will use 1.0.62.0 second from top for winxp.

I could form the decisive capacitor(s) responsible for holding Cmos-content. could shut down PSU. We will see on next start.
Gigabyte was rather not used anymore since last 10 years or less. Was backup when newer Asrock would fail. currently bought again another Asrock. will buit this up with same component and then using HDs which are now running on a half-dead MOBO. halfdead in the manner i cannot shut down PSU.
i know now where the reviving problems were. e.g. monitor had to be triggered sometimes during start. image noch shown sometimes. the same happens sometimes. and boot will stop early. then have to shut down_soft-off.

Please return the mobo to the museum you took it from
Nothing to see here, move along....
