Hi guys, I have had win 2000 running on my pc for the last 3 years. I observed some random reboots during the last few days but today, in the midst of using Firefox, the pc froze completely. Since then whenever I tried to restart it, I saw the following error message: "Windows NT has not found enough extended memory. 7Mb of extended memory is required to run Windows NT. You may need to upgrade your computer or run a configuration program provided by the manufacturer." I searched the MS knowledge base and the only similar issue reported was with Win95. I am using an ECS nForce3-A MB with Sempron 2800 CPU. I have two sticks of 256MB crucial memory. I tried reseating/removing the memory sticks but it didn't help. I cannot reboot with an OS cd also as this error appears during boot process itself. Please suggest what I should do now. Thanks, Nivas

Is the correct amount of RAM displayed at system start, on the POST (hardware) screen? Might consider testing with something like Memtest - at any rate, seems a hardware issue if you're unable to boot via the CD Despite claims to the contrary, posts are not routinely removed from Computing.Net

Yes. I also tried out a new 512 MB in the evening but I just can't get past that error message. The only thing which has worked is booting with a Win98 boot disk but when I do that, I can't 'cd' to my primary drive. 'C:' as shown by DOS is my secondary drive.

You don't cd to a drive but a folder. Command to go to a drive is "c:" or "d:" If your c drive is ntfs 98 can't read it. Download and boot a memory checker to see what it reports. Sounds like a hardware failure. Imagine the power if you knew how to internet search
