2901.1 | Video card problem??? | SUBSYS::WARK | | Fri Jan 31 1997 15:19 | 25 |
| I have seen this problem with some Orchid video cards...
In what I have seen, you don't get BIOS 'beep code' errors,
the drives spin up, no floppy seek... I've always assumed
the system was getting lost in the video BIOS startup
routines... The steps I take when it happens are:
1) Hit the reset button. Sometimes this will work
2) Reseat the video card.
3) Move the video card to another slot (which
is a more advanced reseat. With one
card, moving the slot makes it work
for a while, then it will stop, but I
can get it to work back in it's original
slot, contacts problem, maybe?)
4) Put in a different video card. Put old card
back two days later.
In any event, at least try another video card.
FWIW

| Sounds to me like it could be a power-to-the-motherboad problem.

2901.3 | floppy drive | CSC32::I_WALDO | | Fri Jan 31 1997 16:20 | 3 |
| I had the same problem when I went to a new motherboard. My old floppy
drive was killing it. Got a new floppy drive and cable and didn't look
back.

2901.5 | May be main memory | RTOMS::dhcp-185-48-51.hao.dec.com::WorkBenchUser | | Mon Feb 03 1997 08:50 | 8 |
| I've had that problem going from 486/25 to 486/100 with a new motherboard.
It turned out to be the main memory (I went from Simm to PS/2). Reseating it
made the problem go away.
The machine is working fine since.

| I had a similar problem over the weekend when I installed some
additional memory in my Celebris XL 590. To get at the memory
slots, I had to remove the daughtercard with the CPU on it.
I put in the memory, put everything back, and had the same
symptoms you described. I assume that somehow the new memory
is causing problems. I took out the memory, tried again, still nothing.
I went back, reseated everything I could find (including a
couple of things on the daughtercard) and it worked. I put
the new memory back in, and it still worked.
So...I'd suggest going back and reseating everything in sight
and seeing what happens. I assume you took reasonable anti-static
precautions (touched the case before touching anything else, etc.?)

| Hullo,
for those that are delving into the gizzards of PCs often, a good
investment is an anti-stat wrist-band. After having delved in a few PCs
over the years using the 'keep one arm attached to the case' method,
and now having such a beast - I can tell you the added mobility is a
real plus!

2901.9 | Clock speed? | SALEM::DACUNHA | | Tue Feb 04 1997 06:03 | 8 |
|
Check the clock speed. Some motherboards and associated sub-
systems can't quite handle the CPU-MEM transactions at higher speeds.
You may be limited to to say, 80Mhz.

> The reason I ask, is that I upgraded my children's 386 to a 486/100
Is this one of those special 386-to-486 upgrade chips or do you have
one of those 386/486 motherboards with lots of jumpers?
> All that happens is that a few disk seeks can be heard, then silence!
What is seeking? The floppy or the hard disk(s)? If the hard disk(s),
this would be their own power up re-cal sequence and wouldn't require
the processor to be working. If it's the floppy, the processor must
be working at least partially.

If you haven't already, try removing the extra cache. Did you have
to change jumpers?
Since you're not getting any "beeps" from the speaker, either the
processor/motherboard is not working at all or the speaker is not
connected. I'll bet on the motherboard.
Could you go into a little more detail on exactly what you started
with, what components you used in the upgrade, what jumpers you
changed and what components/assemblies you had to remove?

| re: Note 2901.10 by TAEC::SMITH
Try booting with the absolute minimum memory configuration required
by the motherboard.

The heatsink getting warm means the chip is getting power, that's
about it.
If you haven't touched the cache since you upgraded it (you didn't
say if you had in your reply), perhaps you've got a bad cache chip or
a bent pin? This is the only common thing to both of your processors
that was also changed. Well, except of course for the jumpers. I'm
sure you've probably checked and re-checked them several times over
by now.

Did you check that the speaker wires are connected properly?
Maybe the motherboard is beeping and you can't hear it.
Pull the cache chips out and run without external cache. <test>
pull the new processor <test>
put the cache back in and run with the old processor <test>
reinstall the cpu.

| Is your 486/100 a 3.3 volt chip or a 5volt overdrive chip? I would
think you would need the 5 volt overdrive for this to work.

| Well, one positive thing has come out of this (iro my children):
As the PC has been 'unwell', they have had to remember how to write
again! :-)

| I took the machine back to the manufacturer, who stated that one of the
jumpers was positioned wrong.
[I lost count at the number of times I checked the jumper positions
against the data sheet. One of these days I'll check what jumper has
been changed. Anyway, the machine is functioning fine now - even on
my 2-PC network!]
Martin.
