System rebooting automatically after a change of Hardware.

[Kamesh Akella]

Hi all,

I installed windows2000 prof recently and I replaced the
128MB RAM chip with a new 256MB RAM chip which is
perfectly working on a different PC of similar hardware.

After installing and started the PC, the system gets
rebooted continuosly and I tried with multiple options
like,

Safe mode, Last known good also with a recovery console
option of copying... c:\winnt\repair\system file to
c:\winnt\system32\config directory.

But it is still not getting started and finally I re-
installed everything.

Even the same happened earlier with windows2000 server
also and that time also I done again with re-installing.

Is there any solution, wherein I can simplify/solve by
again re-detecting hardware similar to windows 9x.

Please mail me the links where-in I can know the complete
file-by-file process of windows2000 booting.

Thanks & Regards,
Kamesh Akella

Kamesh -
If W2k runs properly on this machine with the old 128MB RAM chip, but
fails with the new 256MB chip, the problem is not with W2k. The problem
is with the RAM, or the mainboard, or the slot placement of the RAM. W2k
simply uses however much RAM it detects at boot; there is no "RAM
setting". And if W2k detects flawed RAM (according to its very high
standards) it will not boot.

- W2k is much more demanding of RAM than Win9x systems. RAM that appears
OK to Win9x (and to BIOS)may not appear OK to W2k.
- Make sure the 256MB chip meets all the requirements specified for the
motherboard, including which slot it's in, capacity/slot, speed/latency,
and so on.
- It appears from your note that there's only one RAM chip. However, if
there are two or more, they MUST be perfectly matched in every respect.
Ideally this means all came from the same batch when manufactured.
Slight timing differences can scramble the electronics, kill the OS.
- Make sure BIOS sees the full 256MB.

The above is riddled with assumptions about the machine, the RAM, the
OS, and so on - none of which you really described. Hope it helps anyway.
