TROUBLESHOOTING
I keep hearing about people overclocking their CPUs. What does this mean and how do I do it?
Overclocking your CPU means that you are setting the jumpers to make the CPU run faster (e.g. setting
jumpers to 166MHz to make your 133MHz CPU run faster). Okay so now it’s running at 166MHz, but the
heat buildup increases and you will shorten the life of your CPU. EFA Corporation does not condone
overclocking your CPU on our motherboards, doing so WILL VOID THE WARRANTY ON YOUR
MOTHERBOARD. If your CPU was designed to run at 133MHz you should keep it at 133MHz.
I recently upgraded my motherboard on my Windows 95 system and when I started using it, I got a
blue screen that popped up telling me that my system is now using “Compatibility Mode Drivers”.
My system is now running slow because of them and I can’t figure out how to get them off my
system.
Typically Windows 95 will use Compatibility Mode Drivers when you change the chipset and your
motherboard. This occurs because the old IDE device drivers that Windows 95 was using on the
previous motherboard are incorrect, so Windows will try to compensate for this by using 16-bit
Compatibility Mode Drivers. This will make your system’s performance slower since 16-bit drivers are
slower than the 32-bit drivers. In order to correct this, you can reinstall Windows 95 on top of the current
installation and it SHOULD load the correct 32-bit drivers for your IDE devices. However, this does not
always happen, in that case the only solution is to remove Windows 95 and reinstall it from scratch. This
will ensure that you do not have Compatibility Mode Drivers anymore. It is EFA Corporation’s
recommendation that you reinstall Windows 95 whenever you change your motherboard’s chipset.
My system has all the necessary components installed but I cannot get a display on my monitor.
If you have a speaker connected to your motherboard then listen for beeps when you power on the
system. If you hear any beeps then refer to the POST Error Beeps to determine what is causing the
problem.
If you do not hear any beeps then pull all components out of your system and take the following steps:
•
Reinstall the processor, making sure it is seated firmly in the CPU socket.
•
Reinstall the DIMM memory modules and make sure they are securely fastened in the DIMM sockets.
•
Reinstall the VGA card, again making sure that it is sitting correctly in the PCI or AGP slot.
•
Reconnect the power cables to the motherboard, making sure that the AT power cables have the
black ground wires next to eachother when they are installed. For ATX power cables the connector
can only go in one way. Make sure that the power cables are firmly seated in the socket.
•
Reconnect the keyboard.
•
Reconnect the monitor cable to your VGA card and make sure that the connection is secure.
•
Double-check all jumper settings against the Jumper Setting charts to make sure that you have the
correct jumper settings for your processor and power supply.
•
Turn on the Power without any floppy or hard drives installed.
If your system boots, then you will be able to install other components one at a time to determine which
component is causing your system to fail.
If you still cannot get the system to boot, refer to the Special Jumper Settings chart and clear the CMOS
and try to reboot again.
If I am using a 100MHz bus speed processor, such as AMD’s K6-2 300MHz processor do I have to
use PC100 compliant SDRAM?
Absolutely, although some 66MHz SDRAM modules have been able to tolerate the increased bus speed,
it is not recommended to use them as you will shorten the life of the DIMM module and open your system
up to the possibility of a crash.
