When booting 1st thing in morning- Dell Pentium III Win98 (nothing changed) i get BSOD - "system error -Memory parity error detected -system halted". When i hit off buttom or restart, the black screen comes up and quickly displays five lines of typeall saying "PCI Parity Error on Bus/Device Function 008h". When computer reboots it does so in Safe mode or Normal ok. and computer runs fine for the rest of the day. Is this telling me a ROM Chip is going bad or what?

Unplug the computer
Open the system and ground yourself to the metal part of the system.
Disconnect your memory from the systemboard and then reseat the same memory in the same slot.
Repeat with each memory SIMM.
You might also want to make sure that everything else in the system (any daughterboard cards) are properly seated as well.
Close the system and power it up.

Generally the usual (quick) fix with parity errors is to reseat the memory. If your system has been moved recently or the general on/off (heating and cooling) of a system will tend to expand/contract against the connectors and cause this slippage problem.

If the problem persists, then yes, look at the individual chips abd run diagnostics to see which memory address(es) are affected (and thus which chips).

Can you tell me if you have an ATI Rage Fury video adapter? It has something to do with one of your PCI cards. If you have the ATI card try the Microsoft Knowledge Base Article - Q232768.

I do have ATI Rage adapter and updated the driver. So far computer hasn't crashed. Maybe that is the answer. Thanks
