SY-P4RS300 Quick Start Guide
20
3. Clear CMOS battery. (JP5 connector, see the Quick start guide for more info on how to
clear the CMOS).
4. Make sure the power supply you have on your system supports the M/B specification.
Example. If you have a P4 M/B, you need to use a P4 power supply.
5. If you already checked the power supply specification, change the power supply. It might
be defective. The minimum is 350 watt for a minimally loaded system or 400 watt for a fully
loaded system.
When I boot up my system, everything works fine, it sees my CPU and memory,
detects my hard drive, floppy drive and CD-ROM but locks up at "Verify DMI pool
data... ". Don't go any further. What should I do?
1. Clear CMOS battery. (JP5 connector, see Quick start guide for more info on how to clear
the CMOS).
2. If still has the problem, remove all other add-on cards except the video cards see if it boots
further. Then put peripherals in one by one to identify which one causes the lockup.
3. Change the CPU.
4. Make sure the boot device (Harddisk, CDROM, Floppy, etc…) you are trying to boot from
contains a valid, bootable medium or is bootable.
During Boot-up, my computer says CMOS memory Checksum error. What is the
problem?
1. Clear CMOS memory.
2. Redo your CMOS setup settings. If your battery is empty, the error will occur more
frequently. You will need to replace the battery in this case. If the problem persists, re-flash
the BIOS. If all fails your BIOS chip is failing and needs to be replaced.
3. Change the CMOS battery.
4. Re-flash BIOS.
5. The BIOS chip might be failing.
Stability Issues
My system intermittently locks up, very unstable.
1. Check the CPU Temp, it might be overheating. Change the CPU FAN.
2. Do not overclock your CPU.
3. Check the specification of the memory module, maybe the M/B does not support it.
4. Check website for latest BIOS update.
5. Check website for FAQ’s regarding instability issues.
6. Change the memory module or CPU.
7. The power supply might not have enough wattage to support all the peripherals. If your
system has other peripherals connected, like CD-RW, extra HDD, etc. disconnect them.
