Hi, Hopefully someone has a clue where to start looking for the solution to this, as I have pretty much run out of ideas. I have a P2-400, with a PC100 M726 Motherboard, Matrox Mystique G200 Graphics Card, IDE disk + Symbios SCSI card, USB devices, etc, etc. And with this combination my machine is extremely unstable running anything other than Linux (Cool, but I do need to run some Windows stuff) or Win95a. I have tried copies of win98 & win95b, with these versions installed everything s fine for a little bit (approx: win95 3hours, win98 3days) and then the machine starts complaining that It cannot access the registry or that the registry is corrupt and it needs to reboot so it can recover and "safe" copy. The machine has now got to the point where in 1/2 hour I had four registry problems, and it's beginning to take the piss now. What I am seeing is that with win98, I get the message "invalid page fault in kernel32.dll" and then the app closes. I even get this message on the file manager application every now and again (win95 just seems to crash at this point taking the whole system down) Any ideas, on where I should start looking ?

I thought that's just for Win95. I get that problem when I load newer software or use the Internet that much. Just copy user.dat and system.dat in a safe folder. Whenever I get registry problem and check user.dat it's renamed. There's something fishy going on.

You're not alone!! Here's another PC100-M726 with PII-266, running extremely instable, or not running at all. Configuration: 256 MB, WD WD43AA 4GB, Asus AGP 3800, Adaptec 2940 UW, SB-Live. Running W98. Did it right for about a week, then started to show a fully garbled display when in charactermode. Wants to start Scandisk on every reboot, but fails to succeed eventually saying it cannot write to the C: disk. Regarding the garbled display I first suspected the ASUS VGA card so the retailer was kind enough to simply replace it. Unfortunately, the same problems still exist and the shop where I bought the main board has ceased to be. Anyone got a clue???

i have that same motherboard with a PII and it is always crashing. i'm running linux which is generally pretty stable on my other machines. i don't have a solution yet but it has something to do with DMA i think
