| This has been a thorn in my side off and on for 2 years now.
I bought a celeron 433 computer
MB is an Epox BX3 , Award Bios says its a i440 BX/ZX chipset. no problem
with it at all..Except
right from day one we've been having intermittent problems with the
system not powering up. the case has 3 buttons and 3 LED's: PWR button,
RESET Button, and STB button???. as well PWR LED, HDD LED and STB LED
(which is lit all the time). this STB really stumps me. is it STandBy?
I've never seen anything like it. Does anybody know how its supposed to
function?
On the worst day, you hit the PWR button, all lights come on except
HDD....then nothing...no post, no HDD activity, nada.
hold PWR button in for 4 secs....shutdown..push PWR button again lights
come on, nobody home.....push RESET...Voila! post, HDD boot up, no
problem.

| Could be a turbo switch. Just a thought had them on the old 486 boxes
Haven't seen it in a while tho

| I read your MB manual and it appears that it's for Turbo. This is an old
technology and I'm surprised to see it on a relatively modern mobo.
Although the connector itself says "STB", the manual shows turbo.
ftp://ftp.epox.com/support/motherbo...ls/bx300010.pdf
Regarding the power problem - I can think of three likely causes:
1. Do you have more peripherals installed than the power supply can handle?
If you have a CDBurner, a CDROM or DVD, a couple of HDDs etc., the
bare-bones minimum is 250watts, although I'd recommend 300watts. Remember
during POST there's an immediate draw of all devices. This could explain
your problem.
2. A failing power supply. There's no foolproof way to test a power supply
with intermittent problems - so if you've got a spare, give it a try!
3. Improperly connected jumpers. I added a link above to your manual, which
is actually one of the better ones I've seen - it may give you a clue.
Good luck!

STB is the TURBO button... back in the old days you might have to slow
the computer down to run some programs...

| Thanks for your reply,
Ya, I've read the manual 3 times, even found a version at epox.nl that is
version 3.2 rather than version 1. I am leaning towards faulty PSU but its been
like this since day 1 you'd think it would have died already, its been 2 years.
this is all I have running in it:
-floppy
-4gig HD
-TnT2 vid
-generic sound card
-USR 56k modem
-48x cdrom
-1 fan in PSU and 1 mounted on the front
Now the part about the jumpers is interesting, when it does boot properly the
splash screen says Celeron CPUat 433 mhz (66.6x6.5) which adds up, but the
jumpers on the ESDJ (if you saw the mobo layout) are set at 66 mhz and "4x"
multiplier, doesn't that seem odd? I've never done any overclocking so is there
another way the reseller could have overclocked this cpu somehow?(getting
slightly off topic)
thanks

| That is weird! I looked at the manual again and according to that, if
you're running your board at 66MHz, the fastest processor it can handle is a
366 (5.5 x 66 mhz), which makes sense to me (unless your mobo is a revision
of the BX3?
Having a "too fast" CPU, if the jumpers are set to 4x, should only make the
CPU run as a 266 (66x4).
So, you set the jumpers to UNDERclock, whatever is reported during boot is
actually not overclocking, it's what it should be. The part that is weird,
is there is no jumper setting for 6.5x according to the J3 jumper settings.
I wish I could see it myself to help you out. Have you used a multimeter to
test the P1 power connector or the various molex connectors? This could
point to a potential area of concern.

| This is the limitation of e-mail, you can never get all information through in 1
e-mail :-) The board is Rev 0.5, therefore the jumper settings go from 3x to 7x
in .5 increments. check out Rev 3.2 manual
http://www.epox.nl/manuals/mu-bx300032.pdf
doesn't give me a warm fuzzy feeling when the 6.5x setting at 66mhz says
"Reserved"
anyway I've set the jumper from 4x to 6.5x, boots up the same way. but NOW the
video will intermittently cut out and a blinking cursor will show up on the top
left hand corner...aaarrrggg.
No, I haven't pulled out the multimeter yet, the Bios reports that Vcore is
2.03v, Vtt is 1.47v
Vio is 3.42 (which should be 3.3 according to specs, think this is a cause for
concern?)
others are:
+5v = 5.22v
+12v = 12.16v (fluctuates between 12.16 and 12.09)
-12v = -12.09v
-5v = -5.06v
Think I'm gonna go buy a brand new PSU and see what the difference is.

| The voltages all seem within the normal range of fluctuation. That's the
agony of a PSU. If the problem is "intermittent" there's no way to test
except to use a replacement PSU and watch the results.
Of course, if the new one yields the same result, you'd have to suspect the
mobo itself.
I found this via google:
Recommended Processors:
Intel Slot 1 Pentium II (66MHz FSB) at 233MHz ~ 333MHz.
Intel Celeron (66MHz FSB) at 333MHz ~ 500MHz. *
Intel Slot 1 Pentium II (100MHz FSB) at 350MHz ~ 450MHz.
Intel Slot 1 Pentium III (100MHz FSB) at 400MHz ~ 550MHz.
Rev 0.5 (or greater) with atleast 11/04/1999 BIOS additionally supports:
Intel Slot 1 Pentium III 500E, 550E, 600E, 650E, 700E, 750E, and 800E.
* Celeron processors may require additional converter card (EP-S1C). (Do
you have this converter card?)
This link shows what the coltage settings for that card should be:
http://www.elsaco.com/epox/support/bulletin-1259.htm
Finally, here's a guy with your exact problem:
''It just stops loading during the BIOS screens ''
Location: Knowledge Base
Article #: 1094
Product: EP-BX3
Processor: Intel Pentium III 450
Memory: 128MB
Video: Diamond Viper Ultra 770
Hard drive: Quantum Bigfoot 4G, Quantum Fireball 12.7G
Other: CD-R
ISSUE REPORTED BY CLIENT
Yesterday I bought an upgrade for my computer and tried to install it, but
I ran into some problems and now I am at loss. The trouble seems to be with
the mainboard (but I am not 100 percent positive as I may have forgotten
something). When I try to boot the computer everything seems to go well as
long as the bios checks the system: processor is found, memory checks ok,
IDE-devices (both HDs and CDs) are detected and recognized and then it just
stops. After IDE-devices are found, the screen just goes black and the only
thing I can see is a cursor blinking in the upper left corner. The HD led on
the chassis is lit for about 5-10 seconds (but the leds on HDs themselves do
not even blink). It simply refuses to boot from either HD or a floppy disk.
I tried to remove all devices I could, but it did not seem to have any
effect and I have checked the cables several times & tried to replace them,
but the result is always the same. I have also tried to find settings from
bios configuration that would have some effect on it, but to no avail. The
configuration is EP-BX3 mainboard, 450Mhz Pentium III, 128Mb PC100 Original
SDRAM DIMM (bank 0), Diamond Viper Ultra 770 display adapter (which seems to
work fine). I tried to replace it with my old ATI Express+ display adapter,
but that did not have any effect on my problem. IDE-devices: primary master
is Quantum Bigfoot 4G, primary slave is CD (cannot remember what brand),
secondary master is CD-R (Mitsui, I think) and secondary slave is Quantum
Fireball 12.7G (and as I said, BIOS seems to recognize all of them just
fine. It just will not boot from them OR even from a floppy disk) Those
IDE-devices worked fine before I exchanged the mainboard & processor, so I
do not think the problem lies there either. Jumpers on the mainboard have
been set as JP1 = 1-2 (run mode), jp13= 1-2 (enabled), j7=nothing,
j8=nothing, jp3= 4.5X and 100MHz. Am I right when I assume the problem is a
bad mainboard and I should take it back to the vendor for replacement or
could there be some other problem? Thank you in advance.
POSSIBLE SOLUTION
Sounds like a possible motherboard or memory problem. If you have other
memory modules available try using them in the system and retest. Also if
possible remount the motherboard in your case. If neither help then I
suggest having the board replaced.
-Customer response-
I managed to solve the problem and now everything works just fine. It
seems the problem was caused by one of those bolts underneath the mainboard.
(My old mainboard had one more place for screws than this new one has and I
did not notice the extra bolt.) Apparently it touched the backside of the
mainboard and being made of metal, short circuited the mainboard. After
removing that bolt and reinstalling mainboard, everything went smoothly.
