Hi there. Sorry to post another CMOS Checksum Error post but as i've been doing some reseach on the topic i've found that most solutions aren't working for me. When i turn my computer on, only half the time does the CMOS Checksum Error message come up but all times i havn't been able to get into my WinXP machine. it automatically gives me the "windows did not previous start properly" screen with me to choose my options. If i choose Start Win normally the computer hangs on black screen. if i choose any safemode option the computer hangs on loading the file required for safe mode. if i try to boot from xp cd to reinstall the xp the computer will freeze at the start when them files are being loading to start the xp cd. i've tried changing the battery as well as checking everything is firmly connected internally. graphics currently running is onboard. can someone please help with me any suggestionsss... thank you..

Sorry to post another CMOS Checksum Error post but as i've been doing some reseach on the topic i've found that most solutions aren't working for me. Do you mean this post? In any case cannot you just forget about trying to get into Windows? CMOS checksum is hardware-related problem. It needs to be fixed first before Windows will normally load. i_XpUser

Tried searching the web ?? I YAHOO for answers to problems.

CMOS Checksum Failure Problem- A checksum is generated when CMOS values are saved for error checking on subsequent startups. This error message will appear if the checksum is different from one boot-up to the next. Solution- Run the setup program again to correct the problem. I guess setup program is referring to BIOS ?? Like New York City says, hardware problem.

im aware it's a hardware problem. currently i've tried resetting the jumper replacing the cmos battery "load defaults" - bios and had no luck... what else is there to try?? could it be a fauly motherboard.. the motherboard fairly new.??

what else is there to try?? Like the first link list in Yahoo search, leads to a page that lists problems. motherboard, a virus, power supply, battery... --------------------- How PC Power Supplies Work ------------------- Memory(RAM), test program for downloading: http://www.memtest86.com/ ------------------ Harddrive manufacturers have software for download for testing HDD.

now when i turn the computer on the screen is sometimes all lined out and all the text on the memory test screen is jumbled up.. does this help with identifying the problem???
