Make sure the super I/O configuration is setup correctly.
Check for bad sectors on the hard disk (using a program such as
Norton Disk Doctor). This is a common problem with Conner
HDDs. If bad sectors are found, reformat the HDD.
Add-on cards work incorrectly
Check jumper and switch settings of add on cards.
Make sure that the card is firmly seated in its slot. Clean the pins
on the card and the passive backplane connector if necessary.
Make sure the bus speed setting in CMOS setup is 8 MHz. Check
that the shadow RAM and EMS settings in CMOS do not conflict
with the add-on card's firmware and I/O addresses.
Remove (or replace) the terminating resistors on the passive
backplane and test again. These resistors are especially important
for high speed add-on cards.
Real-time clock is not accurate
Under standard conditions the DS-12887 is accurate to within two
minutes per month.
Make sure the application software you are using does not
interrupts the RTC and/or writes improper data to the RTC.
Software
Make sure that the memory, system configuration, display and
HDD space meet the minimum requirements of the software.
Make sure the software is properly installed.
Check for and remove viruses.
