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

ive got d same board as you, and the codes u get given are wrong, theres a reprinted version on the other zenith boards now, i had the same problem, for me it was that i didn reformat my comp, it cud be ur FSB try it on 133
 
thx

thank you.. I#m gonna try that

but now it doesn't boot at all al i get is a green LED from my case but nothing starts to run neother CPU nor Coolers etc.. but if it does I'm gonna try that

BTW did you also have problems with the CMI soundcard??

jonex
 
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
 
By chance,

Have you cleared the CMOS? Checked the PSU?

Heeter
 
thank you all.. I will check the Power supply again-. although i alraedy did once.. but well double check is better ;)

gonna post if sth or not happens

bye jonex

Also Hi EP and people. I found this place again while looking through a oooollllllldddd backup. I have filled over 10TB and was looking at my collection of antiques. Any bids on the 500Mhz Win 95 fix?
Any of the SP crew still out there?

Impressed you have kept this alive this long EP! So many sites have come and gone. :(

Just did some crude math and I apparently joined almost 18yrs ago, how is that possible???
