During Boot-up, my computer says CMOS memory Checksum error.
What is the problem?
1.
Clear CMOS memory.
2.
Re-flash BIOS. Check on how to flash bios on the later part of this
book.
3. Change the CMOS battery, the battery might be drained.
4.
The BIOS chip might be failing.
Stability Issue
My system intermittently locks up, very unstable.
1. Check the CPU Temp. It might be overheating. Change the CPU
FAN.
2.
Do not over clock your CPU.
3.
Check the specification of the memory module, maybe the M/B do
not support it.
4.
Go to BIOS setup and load fail safe settings. Please check if the
system performance in the BIOS setup is set to Turbo/Maximum.
5.
Check website for latest bios update.
6.
Check website for FAQ's regarding instability issue.
7.
Change the memory module or CPU.
8.
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.
9.
Install SiS AGP driver.
My system intermittently locks up, during Windows installation.
1.
Go to BIOS and load "load optimized default".
2.
Check website for any BIOS update.
3. If still has the problem, remove all other add-on cards except
CPU/Memory/Video card/Hard disk. See if you can finish
Windows installation. Then put peripherals in one by one to
identify which one cause the lockup.
