please help me. I have a dell computer its not that old and is a pretty good computer and has quite a bit of memory on it. it goes pretty fast usually and i have not had too many problems with it since i bought it from my friend in february. but recently when i start up the computer a warning message on a black screen comes up and says "Warning System Voltage Low to continue with normal boot up strike f1 to go to (cant remember some diagnostics or utility of some sort) strike f2" and after i strike f1 it boots normally and seems to run fine. it doesnt do it everytime but has started to do it more often now. I am scared that eventually i am not going to be able to boot up at all and all of my home movies and pictures are on this computer and dont know what to do to remedy the problem. I have tried to take the power cord and plug directly into wall outlet and didnt work then i cleaned dust from inside of computer and didnt help either. if anyone knows of anything i can do please let me know. thank you very much! :thumbsup:

Usually this pertains to the CMOS battery on the motherboard. Replace it and you should be fine.

A little more information. This battery keeps the BIOS settings and runs your clock as well. Unless you have made changes to the BIOS there shouldn't be any problem with replacing the battery as they will automatically go back to the default settings. You will need to reset the Date and Time in the Control Panel. To do this go to Start> Control Panel> Date and Time. The rest is pretty self explanatory.

If you haven't made any changes in the BIOS, then there shouldn't be any problems.

Do turn the computer off when you change the battery. You should also touch the metal of the case to discharge any static electricity, this can damage or kill some components inside the case.

I did a quick Google and found a tutorial which should help you with changing the battery.

Any information that is stored on your hdd or your documents will not be affected. Like I posted earlier, you should only need to change the Date and Time.

Your having to ask these questions about the BIOS pretty much tells me that you haven't made any changes there.

If for some reason there has been a change in the BIOS it will not affect your data or any of your programs.

From what you have written, I seriously don't believe the BIOS has been changed from the default settings.

I think you can relax on this one. Take five minutes and a couple of deep breaths, and relax, it's easy. <smile>

Just to put you at ease, if there have been any changes in the BIOS before you acquired it, they will be very simple for us to detect and we can walk you through a simple correction if necessary. OK?
