Memory lost

I have 128 Megs of Memory. It correctly and fully checks all the memory during boot (the whole 128megs worth). However, once bringing up Windows 98 SE, I only have half the memory (64megs). Where did it go!?!?!?

Mowe, when you boot your system, it only validates whether or not the first few bits on the first chip of each module is valid. It doesn't actually test the entire module.

Did you just recently increase ram from 64 to 128?

Open the case and carefully remove the memory modules. Now with a soft dry clean cloth, clean the contacts with something like nail polish remover or lacquer thinner. Do not use anything that would leave a residue behind and do not touch the contacts with your fingers. Now place them back in the slots and try it.

If it does a 128mb check Bios can see the Ram sounds like a windows prob. If you right click on My Computer and select properties. Does it say 64 or 128.

It is definitely a Win Problem. DOS sees the memory, but Windows doesn't. I checked all bios settings and all the windows setting I could think of. It has always worked before, but now, all of a sudden, I only have 64 megs. I also opened my computer, pulled the memory out, put it back in, tried different slots, but still, only 64 megs.

Okay, let's look at some of the other reasons for this to be happening:

This can occur for any of the following reasons:
 
 - Himem.sys is not using all the memory on an EISA computer.
 
 - A driver or program loading from the Config.sys or Autoexec.bat file is
   claiming a portion of random access memory (RAM).
 
 - A virtual device driver loading from the System.ini file is claiming a
   portion of RAM.
 
 - A protected-mode driver is causing the memory mismatch.
 
 - The registry is damaged.
 
 - A CMOS setting is disabling some of the RAM.
 
 - You have the "maxphyspage=" setting in your System.ini file set to restrict
   Windows from using some of the installed memory.
 
 - Ramdrive.sys is being loaded in the Config.sys file.
 
 - You are using a video adapter that is integrated into the motherboard.
 

Let's try this. Rename your config.sys to config.old and autoexec.bat to autoexec.old.

I tried all of your suggestions. None work. I took the memory out and instlled it on another computer and it worked. I'm guessing it's the motherboard.

Sure sounds like it! How many memory slots does this MB have? If you can, remove the module in slot 1 and fill only slot two and see if it will boot. If it will, then exchange modules and try it.

Mowe, for the moment I am close this question with the outcome being that there is a motherboard problem that must be dealt with.

Please note though that even if you should accept this answer along with the dialogue above, you can return to this question as long as necessary to work out any final issues.
