Dear List: This is a computer that I rebuilt for a client that just made
his purchase from another vendor at Christmas. He was under the impression
that he got a PII, but he had a Celeron and was having numerous problems,
all of which resulted from a bad 64MB DIMM board, which has been replaced.
At any rate, I am having several problems, with two almost identical machine
rebuilds.
The rebuild was with ASUS P5A-B mobo, AMDK6-2 400 CPU and Trident Video 87
AGP accellerator (Jaton Corp. -- not my first choice by a LONG shot but I
have a tiny little shop and it was on hand. Original mobo had sound and
video on board and was not compliant with Microsoft gaming . . . client was
a pilot . . . at any rate that is the new components (accepting memory) that
I put in this system.
On rebuild, everything seemed to be functioning perfectly. After three
days, Netscape took a dive. You sent the info on that one for me and I got
that straightened out. Within a week, same old errors started creeping up .
. . blue screens, fatal errors, freezes. I thought, maybe power supply (it
was ATX). I brought the computer back to my shop, changed out the case for
one with an AT power supply (mobo handles both) turned it on and immediately
got a Windows protection error, something the client had reported since the
rebuild. Windows replaced the registry with a backup, machine started up
and ran fine. Shutdown and reboot produced another protection error. Soon
enough, there were no good backups to restore and I was blocked out of
Windows. Scandisk then found multiple problems with directory structure,
long file names, all sorts of bad things. I reformatted.
I ran RAMExam for approximately 24 hours and found no errors. Scandisk
finds no errors on the hd (which is original and a Samsung 4.3 GB). The
ASUS probe was reporting 2.2 core voltage in Windows and I was not
displeased with the temperatures which were at midrange of the probes
acceptable parameters. However, the CMOS NOW shows CPU core voltage (with
no other software installed) at 2.1 . . . which is incorrect. Jumpers
checked, double checked and rechecked, all appropriate (100 mhz frequency,
4.0 clock). I do not recall having specifically check the CMOS for this
reading before changing out the case and may have relied solely on the ASUS
software within the Windows environment (bad, lazy Gina).
*100mhz frequency sets AGP to 66.6 mhz and PCI to 33.3 mhz.*
The rebuild has the following:
Asus P5A-B w/USB
AMDK6-2 400 mhz
1 64 MB 100mhz DIMM board
Trident Video 87 AGP (I think its 8MB, may be 4)
Creative Labs AWE64 (replaced onboard sound - by original vendor)
Samsung 4.3 GB HD (original vendor)
Mitsumi 3.5" Floppy (original vendor)
36xCDROM (Generic - original vendor)
230 Watt AT Case/Power Supply
OS = Win98 OEM
Note: Peripherial software not exceptional: Combat Flight Simulator would
seem to consume the most resources.
2nd Note: Client has been a good student and is not overly curious about
"how" the computer functions. Just enjoys playing and is very intuitive
about general user software operations. Do not believe he is the problem at
all.
I am hesitant about beginning software reinstall until I am sure about the
2.1 core voltage issue. Will check ASUS and AMD sites today for info.
Don't understand why computer began operational difficulties. Any clues???
Second computer is almost identical but probe is reading core voltage at 2.3
but CMOS reads 2.2 correctly, no operational errors, however . . .
Any help you can provide will be most appreciated. I'm stunted.
Thanks tons,
Gina Hunkins
