HELP !!!!!!!

About a month ago my computer was working great. It had been for over a year, since I put it together. It is a 166mHz 686 (IBM CPU) desktop unit used exclusively for home use, with the occasional dog club newsletter, or neighborhood mailing list. Then it started to lock up. This started happening more frequently until it was happening up to three or four times in a 5 hour period. I ran an updated Norton Virus Scan that found nothing. I've removed the partitions on my hard drive and re-formatted it using FAT32, then re-installed all of my software. I had 32 MB of SDRAM (168 pin, 10ns, DIMM) and 16 MB of EDO RAM (72 pin, 60ns, SIMMs) which my motherboard book says will work in the configuration I had it in. After much frustration, I took out the 72 pin SIMMs. It worked great for about 2 weeks without any problems at all. Then it started happening again, with increasing frequency again.

Last night, while in Excel, it stoped operating with the following message:

Excel caused an invalid page fault in module Excel.exe at 015f:300e731d.
Registers:
EAX=062e343 CS=015f EIP=300e731d EDP=0062fbfc

00340031 0030034

This morning the screen saver was on and I touched the mouse to wake it up and I immediately got a blue screen with the message:
WINDOWS:
A fatal exception 0E has occurred at 0028:7fffffff.
The current application will be terminated.
Etc. Etc. Etc.....

These are about the same messages I was getting a few weeks ago, with a few variations. The blue screen was the most common. Sometimes hitting a key clears the problem, just to have what looks like the same message pop up again with only a few changes.

I'm at a loss.
Any help would be appreciated.

Fatal Exception at OE is almost exclusivley a memory problem. Go back to the 72pin SIMMs, remove the DIMMs, and try it out. If the problem goes away, toss the DIMMs and get new ones. If the problem is still there, it is possible, not likely, that both sets are bad.

Note: 72pin SIMMs are usually 5V. ALL SDRAM is 3.3V. Not knowing how your motherboard handles the mixed types or how you jumpered it, the DIMMS may have been getting hit with 5V, damaging them as time wore on.

Hi, my friend had the similar problem too. Since you said that you have assembled your PC a year ago and after frequent use, it may be because the battery is almost dead...and it causes frequent lockups.

I had the same problems a year ago with an older computer. It was all related to bad memory. Thankfully I had a full lifetme warranty with the memory so replacement was free. Try what avatar said about taking out memory and trying different combos. eventually you'll probable find a bad set of memory that doesn't work. then call the manufacturer for a replacement.

I've got the same kind of prob...lots of fatel exceptions I run a cirrix 200+ cpu on a matsonic 5120 board I replaced the original hd with a quantum fireball 3.2g and put in 64 megs ram (edo)and it just crashes faster and faster going to try an amd K6 in a couple of days software probs have been eliminated and there is no dimm in. will post the results of new cpu

To all interested, this problem was solved. Petew had a bad set of DIMMs. Without them installed, everything was fine. A new set was all he needed.
