What's wrong with my computer?

[Evo]

Good day!

My computer is old.
CPU Celeron 667
Mainboard Via Apllo 133 plus(693+596a)
display card Ati rage 128gl
Memory Hynix pc133 128MB

It have a very strange problem,my OS is win98, when extract some files (like

zip or cab) it always display "CRC" wrong.[I'm sure that the files is

OK]

When I setup WinXP(boot from CD-Rom), the setup start copying files,

some files cannot copy or cannot copy correctly, and I fell to retry.

(the WinXP disc is good too) I have changed my hard drive, cd-rom,

memory, data cable,removed sound card and modem, but the problem

remained.

How I can do? Please help me...

That's a strange one. I know you said you've swapped out the memory but I'd
suggest downloading and running memtest86 and leave it running for a while,
preferably overnight. It sure sounds like it may be a memory issue, maybe
the memory bus or the slot-contacts or somesuch.

Just a thought,

You're wrong. If I had to guess I would say you have now, or have
had earlier, memory faults. If you have functioning ECC memory I
am wrong, otherwise you are paying the penalty for not insisting
on ECC in the first place.

as the others have mentioned
it does look like a memory problem

you may want to try clocking your system * down * to see what happens
though

-----------------------------------------------

Since you already have an XP disc, there is no reason to be messing
around with Windows 98. You would be better off troubleshooting your
failed XP installation problems.


"(the WinXP disc is good too)"


Have you tested the disc in another machine to verify this?


"I have changed my hard drive, cd-rom,

"

Try installing XP with the bare minimum hardware. 1 CDrom, 1 HD, Via
Apollo 133 pro + 667 celeron, psu.

If you can, try to find another stick of pc133 (crucial, kingston) and
give it a shot.

If you are truly certain your files are OK and you have
swapped out the HD, CD-ROM, memory, etc., then the problem
could be your motherboard.

I once had a controller fail on my board and data started
getting corrupted all over the place, which included copying
to and from hard drives, CD-ROM drives, network devices --
basically whenever moved it ran a high chance of getting
corrupted. A new motherboard fixed the problem.

Your symptoms sound like failed Cache RAM. That could explain why it
seems to pertain to any files, including those being read off the CD.
Run a memory test that will test Cache memory as well as DRAM. You
might be able to disable the cache ram in CMOS, but it would only be a
means of confirming it is bad as you would not want to run without cache
permanently.

Completely untrue.

Half of win98's problems where resulting from buggy apps and drivers.
A clean win98 install, isn't near so likely to crash as it is AFTER
those buggy apps & drivers are added. Now that the apps and drivers
have matured more, evolved, Win98 is more stable that it "used" to be.
It's just a side effect of these more mature drivers and apps, that
winxp seems THAT much more stable, better.

Sure it has resource limits and other little quirks, but it is still
the right OS to use on any system not fast enough for XP, or for
anyone not gullible enough to pay $100 a pop for each aux PC... Win98
is more than adequate for limited function, special purpose systems.
For a main PC for a power user, of course XP is the preferred choice,
after you strip away all the extra crap running by default.

Not sure exactly what you mean by "cache ram", but the L2 cache is
integral to the CPU, and the main system memory is used for drive
caching, provided a driver is loaded to provide that during the
install.

If your bios (or jumpers) are set to run the memory at asynchronous
speed, FSB + 33 mode, change it to synchronous FSB speed, 66MHz. Try
different memory timings in bios, like "normal", or "10ns", or "SPD",
"Auto".

Check the power supply voltages, preferribly with a voltage meter.
Verify that the heatsink fan hasn't failed, the heatsink is providing
proper interface. On (relatively) cool-running CPUs like that, a CPU
heat problem is more of a gradual concern, it may not outright crash,
but be corrupting things.

Check the motherboard's capacitors, for signs of vented, leaky swollen
or reside. Considering the motherboard age and type, there's a good
chance the caps are poor at this point even if they haven't failed
yet.

caching, provided a driver is loaded to provide that during the
install.

Admittedly the cache is on the processor chip, but if I am not mistaken
it is used every time a file is read from the floppy, CDROM or HD. If
my memory serves me right, it then writes what it has read and placed in
cache into system RAM. This transition from drive to RAM can fail if
the data written from cache into RAM is not identical to what was read
on the drive. I have seen an error occur in the upper portion of cache
not show up until a file large enough to utilize that upper location is
stored. This caused an error when it was read from what was placed in
RAM, because it did not match what was read from the drive originally.
I believe that CRC is a check of the validity of the data against what
was expected, such as the number of ones in a file.

Cache ram is used as part of every processor memory access. During a read
of a floppy or a hard drive doing UDMA, it is read directly into a main
memory buffer, which is often part of the drive cache memory. The L1 or L2
cache only gets involved when the CPU is involved.

If you are getting CRC errors, it is either controller, memory, motherboard
or CPU. If it is all drives, suspect memory, cpu or motherboard. Of course,
drivers associated with any of the above could be the problem.

You didn't mention your hard drive. If its a newer drive, get the
install/diagnostic program from the manufacturer...and make sure
you've set its ATA speed to be compatible to the FSB speed of your
mainboard.

The two must agree...or you'll often get corrupt data.

Good luck.


Have a nice week...

Can you explain in detail how to do this Trent?

(My computer always display "explorer" error and then stop respond, it
seemed to be liked overclocking, but I didn't.)

I lent a keyboard and a mouse from a friend in order to work it out, but the
problem still remain the same. The system clock is 66Mhz, it as same as the
memory clock, and the CL=3. All parts of my computer have already been
changed, except mainboard, display card, CPU and power. in your opinion,
which part is the most like cause this problem?

The memory can be checked with http://www.memtest86.com

The power suppy voltage can be checked with a voltage meter, then
leave it unplugged from AC power for a few minutes, open and visually
inspect it.

Either the power supply or motherboard could have failed capacitors...
bulging, vented, leaky, residue, etc

Remove the CPU heatsink, check the fan, reapply heatsink compound and
reinstall heatsink.

After you've completed these checks, it's most likely the motherboard.

What 'detail'? That's pretty much it. What part didn't you
understand?

So you're saying.....? What are you saying?

If the UDMA capabilities of the drive don't agree with the setting of
the mb, its possible to get corrupt data. For many drives, there is
software to adjust this speed of the drive.
