Computer won't boot. I sometimes get "cmos/gpnv checksum bad"?

Question

I have a
AMD sempron 2600
asrock K7S41GX motherboard,
256 megs of ram
480 watt power supply.

Now I've taken the ram and power supply to the computer store and they tested them both as fine. I've also tried replacing my cmos battery, reflashing bios, and resetting cmos, but I still get this error.

The problems that I'm having with the computer is many times it won't boot at all, not even to bios. I have to turn it on and off many times before the one lucky time that it will boot to bios. And if it does get that far, it nearly always crashes somewhere along the line of booting up windows. There was about 2 times that I luckily did get windows to boot up, and it worked fine for a little while but was short lived because it crashed.

I'm running out of ideas, I'm guessing the processor or motherboard may have gone bad, but I don't want to go replacing good parts. Can anyone help?

Answer 1

It sounds like the bios chip on your motherboard may have been corrupted. It happened to a friend of mine and was a huge hassle to replace. If your motherboard's manufacturer has good customer service they might send you a new one. If not you're probably going to have to get a new motherboard.

Always get current hardware checked by a professional before replacing it though.

I'd start with the CMOS battery first. It can cause checksum errors when you boot. The battery holds all your CMOS settings while power is removed from your PC. If the battery is weak, the settings get lost every time you turn the PC off. Sometimes the battery just isn't in there enough.

Check the CMOS chip itself make sure the chip is seated in the socket all the way.

Bad memory can cause this symptom. Have you changed/added any memory lately?

Clearing the CMOS is worth a try also. There should be a jumper on your motherboard to do this.

Most of all, don't get frustrated. Sounds like you are doing everything step by step, I'm sure it's something really simple.

If everything is in there as it should be, boot up and set your BIOS back to factory default settings. If it starts, then you know everything is good and you can start making changes to the BIOS.

Best of luck to you.

attempt eliminating the battery for a couple of minutes and positioned decrease back in you've gotten to restart some cases if the computing device is kinda previous replace the battery the area huge form is on the battery

Answer 4

what you will need to do is re install your operating system,s CD and then click install, some of the operating system,s are corrupt and the disk cant repair it, will have to reload the operating system all over again, the system will guide you through the process.
