Question about PC Chips M848ALU Motherboard

1 Answer

Just installed new CPU on M848A v2.1 and pc will not POST

I've tried flashing CMOS settings, but no luck. It won't POST with the old CPU now either. I replaced my old Athlon 2600+ Thoroughbred with a 2700+ Thoroughbred, and it won't POST with either chip. I have 2x 1GB DDR SD-RAM pc2700 installed too. I even replaced my CMOS battery just in case! Any ideas how to get things running again?

I flashed the bios on my Asus motherboard M2N-E, and then replaced the processor with a quad. Cleared the cmos and now the computer won't post? What do I need to do to get it up and running again?


Hi,
Try to put back the old procie, if it runs again that means the new procie is not compatible with board.
Read the manual for the compatibilty issue for your MoBo.
Tell me if it works.

I just upgraded to a Elitegroup A780GM-A motherboard, AMD 64 X2 cpu, and 4GB RAM kit. I kept my 250GB Seagate HDD that has XP Pro on it with all my important data. The problem is all devices show ok after...


It is still trying to load the drivers for your old system board which apparently are not compatible with your new board. You need to boot from the XP CD and repair your existing Windows installation. It should redetect all components and install the proper drivers for the motherboard components.

After installing new motherboard and processor my pc doesn't booting. no beeping, no display, no sound but it seem it works, because the cpu fan run well.


Hi achmadjanupe, please include in this post the manufacture & model number of your new motherboard. (That will help a lot).
You must first clear the cmos by moving the cmos jumper to clear & wait at least 10 seconds, than move the jumper back to normal. (See your manual for this).
After installing a new motherboard & CPU it is not uncommon for windows not to boot & you will not hear a POST beep. Try removing your system memory & reseating it. If you have an AGP or PCI-Express video card, do the same. If you are using the same hard disk drive from the older MB & CPU you'll have to do a fresh install of windows, (Including a format of your hdd). Its a very bad idea to install newer drivers over old drivers for a newer board.
The only exception to this would be if the new motherboard is exactly the same as the old motherboard. Once you gain display, go directly into the bios & make sure your hdd is listed in the boot order.
If your hard disk drive is large enough. You can add a new partition within the free space of your drive & install your new windows onto that partition. When you boot to your windows CD follow the instructions on screen to create a new partition within the free space of your hdd. By doing this you'll be able to save all the old data within your old windows drive. You'll be able to copy & past your old data over to your new installation. Once all your data has been copied to your new windows you can delete the old windows & old partition by booting again with the windows CD. Windows can delete the old partition.
There is far too much information, drivers & registry information already in windows. If you try to run your old windows with the new board it will go crazy & you’ll have nothing but trouble.

Good luck achmadjanupe!
This will take some time to complete.
I'm sure you may have more questions, post them here.

Cmos clock will not set !


Is the cmos clear jumper in the wrong position? if it is it will drain the battery and mess up the clock, You may have to flash the eeprom with a newer version BIOS obtainable from the manufacturer, check their website on this to see if it is a known issue ( I have seen this on multiple other manufacturers main boards). If this isnt it it is possible you have a bad clock chip

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.

Problem after updating asus bios


The first thing I would try is to clear CMOS. Either set the jumper on the motherboard to do this, or even remove the battery, and wait half an hour or so. When installing a new CPU, and even RAM, you should always clear CMOS.

OVERCLOCKING FAIL/CPU FAN ERROR


First approach shold be the CMOS utility, check in FAILSAFE DEFAULTS that the error settings for shutdown are either null for overclocking or disabled if you don't have the failsafe defaults on your CMOS utility then set your settings to best performance (should be found on the main page of the CMOS utility). If you are unsure of touching the CMOs then you could try to remove the CMOS battery (small 3 volt battery about the size of a 20 cent coin) located on the motherboard this should reset the CMOS and fix the problem. hope i could help,thanks:)

Try clearing the bios/cmos using the jumper on the board, page 10 in you're manual. Than try booting. See if you're keyboard allows you to get into the bios/cmos. I'm guessing you tried another keyboard? You can also buy a PS2 - to -USB Y adapter. This is what one looks like.

If you bought an AGP graphics card lately you might have also received a single PS2 to USB adapter free. Like this one.
http://www.cablestogo.com/product.asp?cat%5fid=104&sku=35700
It's not uncommon for the the lights to function & yet the keyboard not function. A single pin within the PS2 on the keyboard could be bent or bad or not seating correctly in you're new board.

Tyan Thunder K8HM no POST


It sounds like you?re an experienced hardware guy so I won?t bore you with the basics. When I?ve gotten stuck on a new motherboard no-booting problem these steps have helped me: -Make this as basic a machine as possible. You don?t need much of anything to get the POST to display and anything else just adds more variables. -double check the processor and memory, ensure they are correct for the board. Make sure the manual is the correct one for your board. -Try setting the BIOS to the manufacturers ?Safe? settings or default settings. You might even want to pull the backup battery out, unplug the power supply and let it set for 30 minutes to void the BIOS settings. -Verify the power supply is working correctly, preferably with a power supply tester. If you can?t then try putting this power supply in another computer to make sure it not only turns fans on but really supplies the correct voltage needed to make things work. -Buy or borrow a pre-boot test card. This is a diagnostic card that plugs into a PCI slot of your PC and will give you a much better diagnosis of what is going on. You can usually pick one up for about $35. - Make sure your CPU fan is plugged into the right motherboard connector, the newer boards will check for the CPU fan. I would suspect that if this were the case you would see something on the screen but you never know. Last but not least you might actually have a defective board. Granted it doesn?t happen too often but I?ve had two or three dead out of the box over the past few years. Chances are if you?ve gone thorough all of this and relate the steps to Tyan support they will send you a replacement. And if the new board does the same thing then you only have two remaining variables left; CPU and memory. Good luck and if you have any other questions please let us know.
