hi all

i have a major problem:

i think it's the mainboard since all otehr components seem to work well

BTW i have a 7NJS Zenith board which ships with a 5 1/4 box called Cbox 2 which shows the POST codes on a display

well here it is:

during boot most of the time (~90+% that is) it either stops at POST C3, does a loop upto C3 and back (always reboots upto POST C3) or stops at POST 05

for clearity:

the manual says that:

POST C3 is "Expand compressed BIOS to DRAM"

and

POST 05 is " 3.)Blank out screen / 4.) clear CMOS error flag"

and even if a manage (that's the wrong word.. better: if i'm lucky enough) to boot the machine it shuts down all of a sudden after a nondefinite time (may be days, may be 10 mins... random)
and it's not the CPU since i checked that with MBM5

does anybody know what to do??..
i really need help on that since now it's only luck to get the machine to boot through

thank you

maybe it could be power supply? if you got another maybe check that. if you psu is going it might not have the power during boot and would also cause random shutdowns/reboots.

ive never used the onboard sound on it its disabled along with Nviidas lan, cos i dont like um, and if the fans dont start then it sounds more like a power prob

Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS

Been running around Quora lately, luv it there https://tinyurl.com/ycpxl
