Hi! The problem started on my personal computer, Compaq Presario running Win98. My computer was lagging horribly so i decided to run scandisk to see if I could find something wrong with it. The computer froze during the process. I rebooted and windows froze immediately after begging to load. I rebooted into Ms-Dos and got this error: HIMEM.SYS is missing Make sure that the file is in your Windows directory We've replaced the fiiles, checked config.sis msconfig, command.com, autoexec.bat and everything sure appears to be in perfect order. While accessing my personal computer through the network from an additional computer, Eventually the 2nd computer developed the same EXACT problem. Both computers cannot boot in safemode, they cannot log into windows from Ms-Dos. I believed the problem sounded like a virus. I searched all over the web and found nothing about a virus that causes this kind of problem. can anyone help me out? This is driving me insane!

Do u have an anti-virus program... Is it updated? If u need to a free AV go to www.grisoft.com. If u need a more competent scan, then go to: http://security.symantec.com/ssc/vc_scan.asp?langid=ie&venid=sym&plfid=23&pkj=XPNHRHYTINMHDKDCWLL. I don't doubt u've tried this or have an AV, but u didn't state it. But ya, sounds like a virus. U should probably post this in the "Security and Virus" section. Cheers.

Hi all, Start the computer with a Win98 boodisk. Do you still receive the message? Mesich

Download HIMEM.SYS it's not that difficult,had the same prob whilst runningWIN 3.1 after it worked perfectly normaly. Good luck

You say you've checked your AUTOEXEC.BAT and other files,thats good also make sure WIN is the last command in the AUTOEXEC.BAT file and watch out for using a different set of capital or small letters when calling these files up as they duplicate depending on which one you use. For example call them up with: EDIT C:AUTOEXEC.BAT---or EDIT C:Autoexec.bat

ok, I gotta say this.... 1. win98 will boot to the gui regarless of if you have "win" as your last line in the autoexec or not. It's not based on that anymore, it's based on a setting in the msdos.sys (bootgui=1). Also, on systems running any microsoft os, filename case doesn't matter. If you were running linux, then yes, Autoexec.bat and AUTOEXEC.BAT are different files. But not on a windows o/s machine. Microsoft has a few things to say about your problem... http://support.microsoft.com/default.aspx?scid=kb;en-us;296636 http://support.microsoft.com/default.aspx?scid=kb;en-us;116253 Check to see if those help you out, and do scan for a virus though, regadless of if this helps or not.
