SY-P4RS350 / P4RC350 Quick Start Guide
The system turns on for some seconds then shuts down by itself.
1. Check if the CPU fan is connected to the CPUFAN1 connector.
2. The CPU might be overheating. Check the CPU FAN if it is defective or see if
the CPU fan is in contact with the CPU.
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.
