Intel 845gvsr mainboard no display problem

this problem is normal because of the BIOS chip failure normally

when u get ram out and start computer it gives beeps and when u put back the ram and power on PC it gives no beep no display.

Fix the problem:
tools required:
1. hot air gun
2. 512kb fresh bios chip/ if the old chip is right then no need of newer one
3. p3 mainboard (with the BIOS socket) for reprogramming the chip
4. dos bootable hard disk
5. bios bin file.
have not the file ,
don't worry: this file can be made from the bios chip of a working mainboard using the bios flash utility.
flashing software: best is Uniflash.

1. with hot gun, get the bios chip out of the board,
2. reprogramme the chio with correct bin file.
3. put the bios back

copy the file in dos bootable hd
run the hdd on p-3 board
pull the bios out of running board (with slight care)
put the 845gvsr bios chip in place of p-3 bios
run uniflash and flash the bios
power of p-3 computer and get bios out

Location of bios chip on dell Inspiron 1764

The BIOS chip is soldered onto the motherboard. It is about a 1/2" square chip. The below link is the Dell Inspiron 1764 Service Manual from Dell for the Inspiron 1764. It is in PDF format (Adobe Reader online file, and downloadable).

Opens in Adobe Reader so make sure you have the program already installed, or download and install Adobe Reader from first.

Once the Service manual is opened. Go to the: System board section. Then scroll down to Replacing the Coin-Cell Battery Click on the link...That is the BIOS chip battery. The actual BIOS chip is not a removable chip on that particular motherboard, but a soldered in place chip located on the opposite side (surface of the motherboard) right near that coin-cell battery location. That chip may be reflashed w/ the latest BIOS by downloading the latest BIOS.bin file avail. from DELL at the following Drivers link.
Choose Drivers and Downloads from the left>Choose the installed OS Version first>Then choose BIOS from the list. The following choices are there; (only 1 version of OS avail. without the actual Service Tag # appears; Win 7 (64 bit OS)).

Windows 7 64 Bit>Latest BIOS file version is A13 (Released 06 Apr 2011) If that matches your OS (Go to Start>Control Panel>System>General Tab and look for Windows 7 and 64 bit as the type of OS installed, you can also download Belarc Advisor from and install and run it, allow the hardware and software inventory to load (print out the inventory) if possible, on the right near the top the System board info and currently installed BIOS info will show on the inventory along w/ everything else about that current laptop setup), if so, and Win 7 64 bit shows and the BIOS version is anything less than A13 (a smaller # like A6 or A11...then you need to update the BIOS to the A13 flash), is listed, go download from dell the A13 file, and install to flash the BIOS to the A13 latest BIOS version released. Then delete that downloaded file. You only need to flash it once.

Or go to: Choose Support>Look on the bottom of the laptop for Service Tag: Number or Tag: and enter the # printed there usually a short combo of letters and #'s. Or you can have it scan for the tag # by installing the provided program. Then once you are at the Inspiron 1764 location>Enter your Operating System Version or flavor installed>Choose Drivers. In the Drivers section choose BIOS, and look for the highest BIOS Version Number and latest file date created.

IF THE MOTHERBOARD will not boot to the BIOS setup Screen (Motherboard BIOS is BRICKED or DOORSTOPPED=Corrupted BIOS, usually caused by incorrect flashing w/ the wrong file, or an inturrupted flashing...Though, sometimes just a dead motherboard BIOS coin-battery type battery replacement, and re-flashing with the latest file will cure the issue though).

And should a new preprogrammed BIOS chip be required to UNBRICK THE MOBO, for the Inspiron 1764. One can be purchased on ebay at the following link, but should only be installed by a VERY qualified technician. (Notice it says on their pic....New chip to be soldered on board). That takes skill to properly handle, desolder and resolder the chip properly. DELL and others can also reflash bricked BIOS CHIPS. Chips that were flashed incorrectly turning the motherboard into the dreaded doorstop.

But if the BIOS setup is reachable (the computer will start and boot to at least the BIOS Setup screen...Usually F2 or F10 or Delete keys. Just watch the screen on boot up, choose the BIOS Setup or Setup key combo listed). If so, (you can get to Setup, then the BIOS Chip is not bricked, corrupted, damaged, or doostopped), In that case, just go download the latest BIOS Version .bin file from the above Dell Drivers Link for your OS version, and go into Windows and double click the file w/ the power adapter plugged in and all other programs closed...follow the instructions, and do not interrupt the BIOS Flashing process (very IMPORTANT!) The computer will simply restart after the BIOS flashing is completed...You may have to go back to setup after it restarts and load default settings if it does not load Windows after the flash, then restart again.

Good Luck!

My bios is corrupted how can i solve the problem

You can remove the battery to clear the BIOS - read the information from this link.

Although the link is about removing the password, the same things need to be done to reset BIOS to factory default.

Well u cant change the bios its soldered to the motherboard. If you can at least see the boot screen as a last resort you can flash the bios chip. However that is an absolute last resort to flash the chip. How are u so sure its the bios?

Bad bios flash, backup gives bad checksum error. downloaded correct ver - still bad checksum. what should I do? AMI bios ver 1.0

Is the mother board working? If so, why are you flashing the bios? If the bios is bad and can not be flashed, you may be able to buy a pre-flashed chip if it uses a removable flash chip. Try this site but you can find others on the Internet.

Good news, you can save the machine, although it may take a while. There are a few ways to do this. If you are lucky enough that the boot sector of your BIOS didn't get corrupt and your computer still posts and you can put in a floppy. Then all you have to do is follow your normal dos based flashing and it'll replace it no problem. Now...the problem REALLY arises when you’ve flashed your BIOS and the next thing you know you've received the black screen of death. No beeps, no video, power on, and that's it.....this is when you've officially turned your board into a circuit filled paperweight. If you happen to have the EXACT motherboard laying around then you'll be able to save yourself some money. It has to be the EXACT motherboard, no exceptions. If you have an NF7-S v2 then you need an NF7-S v2 board...period. There are a special set of tools you need to remove the BIOS, but if you're feeling brave and like to really take your chances like myself...then get a strong paperclip and bend a little hook at the end and I mean little. The bend needs to be maybe a quarter of an inch. You can then put this in one of the open corners in the socket the BIOS chip sits in. Use the little hook to get it under the chip and pry it out. This won't work if you use a small wimpy paperclip so make sure you get a big thick one that’s a little difficult to bend. Remember....a paperclip is metal....metal is conductive....if you stay in the little corner and get under the actual BIOS Chip you will be fine...avoid touching ANY connectors within the BIOS socket or anything around. If you use some electrical tape to thinly wrap the paperclip, you now have a rubber non electrically conductive BIOS removal tool! Remember don't just wrap the tape around the paperclip but also over the tip. It doesn't help to make the stick of the paperclip non-conductive just to leave a nice little tip for something to spark to. If you use some electrical tape to thinly wrap the paperclip, you now have a rubber non electrically conductive BIOS removal tool! Remember don't just wrap the tape around the paperclip but also over the tip. It doesn't help to make the stick of the paperclip non-conductive just to leave a nice little tip for something to spark to.
I've removed my BIOS chip with the system turned on many times using this method but don't come crying back if you stick in a paperclip and you get a nice jolt.

You can see a picture of the appropriate BIOS tool here:

It's the black pair of large looking tweezers.

That image came from this site

Which offers what is called a BIOS Savior which basically allows you to have two bios chips and if one fails then there's a switch that allows you to switch to a working separate yes essentially you have Dual BIOS, but only one is active at any given time.

Back to hot flashing....what this means is that you will be removing and replacing the BIOS chip while the system is 'hot' or otherwise...turned on. To hot flash your corrupted first need to remove the corrupted BIOS chip from your board. From here place in a non-corrupted BIOS chip. Remember...the BIOS chip you use has to come from the EXACT board that you have. So if you don’t have another copy of your motherboard you can order a new BIOS chip and when it arrives you can then use the Hot flash method to restore the corrupted BIOS and then you'll have two BIOS chips incase again if one gets a failed flash.

You can get Spare BIOS chips from

So now that you've got your new BIOS chip you can either pop it into your board and be happy with it and throw out the other BIOS chip or you could do the better nerd way and hot flash that corrupted puppy! What you'll need to insert your new BIOS chip. Make sure that your floppy is first in the boot sequence. Also it's a good idea to go ahead and remove your IDE1 and IDE2 connections to ensure it goes to the floppy. DO NOT put in your floppy yet as we need to put in the corrupted BIOS chip before the disk starts. If the disk is not in there it'll simply say INSERT SYSTEM DISK AND HIT ENTER TO RESTART. Getting to this screen is perfect as you don't want the system to try and boot from your HD into windows and you just need it to sit at a part where the system is accessible and the floppy will still be accessible.. At this point you need to have your bootable floppy with flash utility on it near by as you'll be using it within 5 minutes. Before you put the floppy in, first remove the good BIOS chip currently in the system. This is where it gets dangerous especially with a paperclip. Your system has to remain ON as the only reason it was able to POST is because it had the proper BIOS in it. After the computer has POSTed the BIOS information is basically no longer needed so it's safe to remove the BIOS chip even when your system is on.

So hopefully at this point your computer should be on and wanting a disk to boot from in the floppy. Remove the good BIOS chip and replace it with the Corrupted Chip. Now you may insert the floppy disk and flash it just like you would normally do a DOS based flash. If you have the autoexec file that came with the flash utility, then as soon as you stick in the floppy it'll start up and flash your corrupted BIOS with the files you select and are hopefully the right ones. Hopefully the flash is a success and then will now have 2 working BIOS Chips with the exact same information on it. So in the future if another bad flash occurs you can once again hot flash the chip to restore it or simply put in the spare BIOS chip until you have time to hot flash it.
