Now by PC chips do u mean CPUs? because if so then yes your motherboard is dead but im not sure if it would be BIOS related. There should be a battery somewhere, one like a wristwatch but bigger and flatter on the motherboard, look for it and replace it and test if it works, otherwise it is most likely your motherboard is dead and you need a new one. There is a way of fixing the BIOS if that is the problem. Its called Force Flashing BIOS. I Don't know too much about this but apparently its not hard. Google It and see what you come up with

Hope This Helps

3 Short beep and 1 long beep and blank screen. My


That means there is s problem with the RAM on the motherboard (Problem lies with the Memory Chip). This could be a result of a Memory chip that has not been inserted properly or it has moved away from its contacts on the motherboard. This will be fixed by opening up the RAM compartment and remove the memory chips and replace them back carefully. Try to switch on your laptop again. Make sure that when you are doing all this, the computer is off and the charger is not connected to it. This I hope will solve your problem.

Hi Sue.

Remove the power cord from the back and then take out the motherboard battery for half an hour (you need to remove the side panel from the case to access the motherboard) after the half hour is up pop the battery back in and connect the power cord, see if that resolves the problem.
The fact that you can hear 1 beep indicates that all is fine so I doubt you have fried the BIOS chip.
Also, if you have a stand alone graphics card installed remove that and clean the contacts, then reinsert it.

Plesae post back if you have more problems.

Good luck.

Got a problem with my pc. It suddenly intermittently doesn't POST. It boots 1 out of 15 times. When not booting, it turns on, no beep, after 2 seconds, turns off. Then I have to wait around a minute before...


It may be that your motherboard is dead. I have had this problem before. Here are some things you can do to troubleshoot:

Remove video card then plug back in or try alternative video card if you have one.

Isolate each memory stick in your RAM. This may identify RAM problems.

Try a different power supply in your PC or at least reconnect every connection for your current power supply.

Try clearing the CMOS by switching the CMOS clear jumper

Pc keeps beeping 3 times and nothing on the moniter


remove the RAM(MEMORY CHIPS) from *********** board and reinsert.if the problem is same replace the chips,get new chips.mostly cleaning the golden lines on the chip with pencil/school rubber solves the problem.
No beep is usually a power problem that can be related to the power supply, motherboard or both. Always check your battery power before thinking there is a bigger problem.
Step3
One beep is a normal POST. That means everything is fine. Two, Three, or Four short beeps are normally about the memory of the machine. If there is a problem with one of your memory chips you should get beeps of different combinations in this area. If you get two or three short beeps, one or both of your memory chips could be in trouble.
Step4
Five beeps point toward motherboard or CPU problems. Make sure your memory and video card are seated properly. Try removing them and putting them back in, only if you are comfortable with computers. Six, seven and eight beeps. Eight beeps indicate problems with your video card. Six or Seven are CPU, or a bad chip on the motherboard. Nine beeps mean the BIOS is bad. Replace the motherboard. Ten beeps means the problem is in the CMOS. All chips need to be replaced.
thanks.

MSI K8N NEO2 Platinum NOT Posting + No beep + No display


try to test the CPU on another machine ...

or at least remove it and reinsert it.

But if u say that u reseted the BIOS an it still not doing the post, it just could be that the motherboard is out !

It can also be the PSU as u say, but i doubd it ! Try to remove all hard drives, cdroms, etc... to limit the power usage... and see if it passes the post.

U can also try to remove the motherboard from the computer case and put it on an insolating surface and than try to boot (sometimes shorts appeare betwen the motherbord- case - psu)

PC Chips M848A dead, no screen output or blips


I had the same problem. I bought the M848A from Newegg in an attempt to save my trusty Athlon 2600+ CPU and a fancy Raedon 512mb AGP card which I salvaged out of my old broken down system. I thought it would be a good time to update the RAM so I bought 2 gigs of OCZ 3200 DDR400 to go with.

Problems:
(1) First the damn thing wouldn't boot past the post screen. It would simply cycle thru post over and over. Fixed: The microsoft XPpro operating system was corrupt. The new board hated the old configs from the previous system. After trying (and failing) a os repair, I ended up simply doing a clean intall with great results. Board was stable worked great for a week. Only had one glitch...

(2) The board would only recognize and post ONE of the 2 gigs of ram I bought. I raided all the CMOS settings, and downloaded all the user manuals I could get a hold of and found no answers to this curious problem. On a whim, I opened the case and switched their locations back and forth which led me to...

(3) Lights on, no one home. All the lights came on... power, HDD, cd drives... all the fans worked: case, CPU, graphics card... but the screen would remain blank/unpowered and no post menu would come up. Seemed like it wanted to work, but simply stopped short of booting up. THIS WAS YOUR PROBLEM?!?? On a hunch, (more an angry impulse) I reached over and popped an old Mushkin Technologies (PC 3200 400DDR) 512mb out of my old dead mobo and slammed it solo in the primary memory slot. Bingo. Fired right up.

The board appears to be testy with its RAM... If it fails its initial memory test, it will not post. The screen will not come on. I'm not 100% certain this is the final solution to the problem... I'm still playing with it. My questions now are.... do I have dead RAM? Chip compatibility issues? Perhaps the PC Chips support techs on their website have some practical advice on this issue. I'll keep you posted if you like.

AMI BIOS Beep Codes

 1 Short Beep One beep is good! Everything is ok, that is if you see things on the screen. If you don't see anything, check your monitor and video card first. Is everything connected? If they seem fine, your motherboard has some bad chips on it. First reset the SIMM's and reboot. If it does the same thing, one of the memory chips on the motherboard are bad, and you most likely need to get another motherboard since these chips are soldered on. 
2 Short Beeps Your computer has memory problems. First check video. If video is working, you'll see an error message. If not, you have a parity error in your first 64K of memory. First check your SIMM's. Reseat them and reboot. If this doesn't do it, the memory chips may be bad. You can try switching the first and second banks memory chips. First banks are the memory banks that your CPU finds its first 64K of base memory in. You'll need to consult your manual to see which bank is first. If all your memory tests good, you probably need to buy another motherboard. 
3 Short Beeps Basically the same thing as 2 beeps. Follow that diagnosis above. 
4 Short Beeps Basically the same thing as 2 beeps. Follow that diagnosis above. It could also be a bad timer 
5 Short Beeps Your motherboard is complaining. Try reseating the memory and rebooting. If that doesn't help, you should consider another motherboard. You could probably get away with just replacing the CPU, but that's not too cost-effective. Its just time to upgrade! 
6 Short Beeps The chip on your motherboard that controls your keyboard (A20 gate) isn't working. First try another keyboard. If it doesn't help, reseat the chip that controls the keyboard, if it isn't soldered in. If it still beeps, replace the chip if possible. Replace the motherboard if it is soldered in. 
7 Short Beeps Your CPU broke overnight. Its no good. Either replace the CPU, or buy another motherboard. 
8 Short Beeps Your video card isn't working. Make sure it is seated well in the bus. If it still beeps, either the whole card is bad or the memory on it is. Best bet is to install another video card. 
9 Short Beeps Your BIOS is bad. Reseat or Replace the BIOS. 
10 Short Beeps Your problem lies deep inside the CMOS. All chips associated with the CMOS will likely have to be replaced. Your best bet is to get a new motherboard. 
11 Short Beeps Your problem is in the Cache Memory chips on the motherboard. Reseat or Replace these chips.
1 Long, 3 Short Beeps You've probably just added memory to the motherboard since this is a conventional or extended memory failure. Generally this is caused by a memory chip that is not seated properly. Reseat the memory chips.
1 Long, 8 Short Beeps Display / retrace test failed. Reseat the video card.

sounds like the motherboard has failed. I had those same symptoms this summer. Replaced m/b and it's good again.  Did you count the 'continuous' beeps? That's a code to say what is wrong.

Beeps along


Hi, Past experiences with different models of Asus of this type of problem indicates BIOS problem. I have not come across the same symptoms with ECS, Intel, MSI, Gigabyte or others but once in a Samsung. The beeping sound is actually up down (like old ambulance siren). I have tried some correctives measures with varying results: 1. Clean the motherboard with a strong solvent, hot air dry with particular attention to the BIOS chip; 2. Resolder the bottom side of the motherboard particularly the chip holder of the BIOS; and/or 3. Flash the BIOS chip using an identical motherboard or an EPROM programmer. If all else fails, am afraid you have to replace your motherboard. Good luck and pls post back how things turn up or if you need further information. Kind regards.
