Often when I boot up my win95 notebook, I get the error msg "ERROR: HIMEM.SYS has detected unreliable XMS memory. XMS Driver not installed." I'm then prompted to hit enter to continue loading Windows, after which I get the msg "HIMEM.SYS is missing... press Ctrl-Alt-Del to restart." But restarting just brings me back to the same place. I find this always happens after I have left my notebk idle for a long time, then try to reboot. What should I do? Thanks in advance. Cal

Hi..U are having a problems with the device driver for extended memory and the high memory area(HMA) .Himem.sys.and u will continue to Receive that error if U dont fix -it..However try to add a : device=c:\windows\himem.sys line to ur config.sys. .another possibilities ur physical Ram maybe faulty...laters,Dianna.

Cal: After I had built my first desktop about a year ago, the same messages came up. It did not crash although I had no idea what was happening, so I took the clone into a computer repair store. The techs had it for about 6 weeks and finaly came up with a compatability issue, with my video card. In my case it was happening about 1 in 4 or 5 bootups. I had them install a different brand [known compatible], and this has not happened again. I hope this may give you some insite, Doug

The unreliable XMS memory message usually means faulty ram or external cache. However in your case (laptop, rebooting) there may be a different explanation and fix, see: http://nospin.com/pc/pcs05-8.html
