computer doesn't boot after upgrading memory

[rxrx]

I have a AMD-K6-2 350MHz computer, and the video is integrated into the motherboard with 8 MB shared memory. It has 2 DIMM slots. Slot 1 cane factory-installed with a 32-MB memory module. Recently, I added a 64-MB upgrade memory module from Kingston to the remaing slot, but the computer could not recognize it. Then I decided to try to put this 64-MB upgraded memory board to slot 1, and then moved the factory-installed 32 MB-memory board to slot 2. Ater that, I turned on the computer, and it could not boot. All I heard was a continuous non-stop long beep, and there was no input to the monitor. This problem persisted even after I put the memory boards back to the way they used to be! I have no idea what to do now! Could anyone give me any suggestions on how to fix this problem, I would really appreciate it. Thanks very much.

Check the motherboard manual, to see what type of memory it supports. Is this the right type of memory you are trying to install ? Also check what is the maximum memory your motherboard memory slot can take.
Let us know maybe we can help from there.

Thanks for your response! I checked, and my mainboard can take a maximum of 256 MB, and each individual slot can take up to a maximum of 128MB. The factory-installed memory board and other upgrade memory boards I have are all of the same type: 3.3v, 100MHz, PC100. I also tested the factory-installed memory board on another computer and it worked! My problem now is that even with my old working memory board I can't get the computer booted up even past the point where I can access the CMOS settings. Do you think my problem has something to do with the CMOS settings. I would appreciate your suggestions! Thanks

Is there a way you can check the new memory on a different computer to see if the memory is good or bad ? Is there any jumper you need to set on MOBO for extra memory ? I'm not sure about K6 MOBO's. I'll try to get back to you soon.

Hi folks, I have had EXACTLY the same problem... Well, my brother did. I gave him an extra 64 Mb sdram which he inserted into his k2 350 Microstar 5169 m'board and it did not boot, it did nothing. He took it out and rebooted, only it did not. He then passes it to me to "fix".. I have reset the bios by resetting the cmos. I have checked his current ram, which is fine. I tested it by putting it into my machine and it was seen ok. The hd spins up on power, the fd power light is on, the cdrom spins up, with bootable cd in. Still nothing. The system jumpers are undisturbed and in the right place. I have checked the seating of all cables and power leads.I put in another working graphics card - no joy. The odd thing is that there are no post beeps. Suggestions as to what else I can try are most welcome. One thing - I'm not sure if it's important; there was no fd seek heard?

Folks; help! please..

If all else fails - I'm going to have to get him a new m'board. There is only one last thing to test by my ligts and that is the cpu. Got to find someone else with an atx socket 7 board and check it on that.

Folks, I found the cause of my woe; the cpu was damaged. Ghod knows how? Just from a memory upgrade. A mate brought round his pc and I tried the chip in his, no joy, we then tried his chip in my pc - all was light and beauty.
/me wanders off towards AMD with large stick in hand.....

Hi you guys! I checked very carefully to make sure everything on the mainboard of my computer was undisturbed or seated properly or correctly, but I still wasn't able to get the computer to boot. Because I bought the new 64-MB upgrade memory module from Kingston, I called Kingston technical support. They were very helpful! At first, they told me to change the position of the CMOS jumper on the mainboard to clear the CMOS. I did that, but then my computer would not turn on (the fan didn't turn on). I called them back, and they told me to bring my computer in. I called them back after three days, and they were able to get my computer not only to be able to boot with my original memory module but also to recognize the new memory module. I don't know how they did it, but they did a good job. My guess is that the problem wasn't about the CPU or CPU compatibility, but that it had something to do with the system hardware configuration, and you can reversibly change the system configuration to adapt to new conditions. Thanks for your answers, and Happy New Year!
