PC not booting up
Troubleshooting should follow this logic:
1. Start Win95/98 in Safe Mode. If the trouble does not appear in Safe Mode, then the trouble is caused by software conflicts or defects. Investigate each of the functions that Safe Mode turns off. 2. If the trouble also occurs in Safe Mode, rename the current Windows folder and reinstall Win95/98 into an empty folder. If the trouble does not appear with a fresh installation, the trouble is caused by something you have added to Win95/98 (but something that is not turned off by Safe Mode). 3. If the trouble occurs even with a fresh install of Windows, the trouble is arising in hardware. Safe Mode does the following: (a) bypasses config.sys and autoexec.bat (b) prevents programs from starting automatically (from win.ini or the startup folder) (c) uses standard VGA video (d) prevents a network from being started (e) disables protected mode device drivers (those listed in Device Manager) (f) bypasses the [boot] and [386Enh] sections of system.ini For more details, see document 122051 in the Microsoft KnowledgeBase. If Safe Mode makes the problem go away, you can try tests from the list below to pin down the cause of the problem. For more elaborate instructions, see document 156126 in the KnowledgeBase, which explains how to do troubleshooting in Safe Mode. With Windows 98, you can use MSConfig to help you run the tests below. With Windows 95, you can use Startup Control Panel. Startup Control Panel is similar to the Msconfig utility that ships in Windows 98. It can make troubleshooting easier by removing and restoring items from the Windows startup. You can get Startup Control Panel as freeware from: http://home.ptd.net/~don5408/toolbox/startupcpl/ Startup Cop can also disable items loading at Windows startup and it is freeware. You can download Startup Cop from: http://www.zdnet.com/downloads/stori...0,,77594,.html 1. Change the video driver to Microsoft's Standard Display Adapter (VGA). Restart Windows and test. 2. Rename the Config.sys and Autoexec.bat to Config.sss and Autoexec.bbb, or edit them so that the only things loading are absolutely necessary for the computer to run. The latter items might be a SCSI driver for the harddrive, or disk management software for an EIDE drive. Deactivate EVERYTHING else by putting REM in front of that line. Reboot the computer and test. 3. Remove EVERYTHING from the Start Menu/Startup folder by dragging their icons onto the desktop. Also disable or uninstall all utilities that are running TSR (such as Norton Navigator, SoftRam or Macafee AV). Restart Windows and test. 4. Rename the Win.ini and System.ini to Win.iii and System.iii. Then make a copy of System.cb and name it System.ini. Do not rename System.cb itself. Edit the new System.ini as follows: Add device=*vmd to the [386Enh] section, and add drivers=mmsystem.dll mouse.drv=mouse.drv to the [boot] section. Restart Windows. You probably will have no mouse so you'll have to use keystrokes to do the following. Go into Device Manager and select the mouse (which will have a yellow exclamation point). Click "Remove." Again, restart Windows. Windows should find the mouse and install software for it. Test. 5. With Windows 98, run the System File Checker. Go to Start/Run and enter "sfc". 6. Rename the current Windows folder (directory). Then install Win95/98 to a new, empty folder. Test. If problem does not occur, it was caused by something in the old installation. I recommend that you keep this new installation and reinstall your Windows applications. When you reinstall applications, install Windows applications that were written for Win95/98 or WinNT but do not install older applications that were written for Windows 3.x. Install only one application at a time and test the system thoroughly before installing another application. Before you install and application, make a system snapshot with a program such as ConfigSafe; this will allow you to revert to the previous situation if (when) you install an application that causes trouble. With Win98, it is also possible to run "ScanReg /Backup" before you install an application, which allows you to restore the Registry if (when) you install an application that causes trouble. However, it is safer to make a complete system backup and recovery with ConfigSafe or a similar product. The following articles explain how to install into a new folder: How to Reinstall Windows 95 to a New Folder [142096] http://support.microsoft.com/support...s/142/0/96.asp How to Install Windows 98 to a New Folder [193902] http://support.microsoft.com/support...s/193/9/02.asp Information about reinstalling is also on www.windowsreinstall.com.

many thanks. i will use this as a last option, i have
found a way to bypass the antivirus check in the autoexec.bat file. -----Original Message----- Troubleshooting should follow this logic: 1. Start Win95/98 in Safe Mode.

PC not booting up
Yikes. That recently happened to me, & I was about to finally bite the
bullet & uninstall McAfee myself, after it would not update well a second time. However, I went to the site... http://us.mcafee.com/ ....& clicked my way to a download of the latest "Superdat" (SDAT4367.EXE, back then anyway). The site did say McAfee v.8 cannot update by way of Superdat, though. It carried with it the latest virus defs, in addition to "whatever". Seems to have gone in well & quick. I see the three ".dat" (Clean, Names, Scan) in "C:\Program Files\Common Files\Network Associates\VirusScan Engine\4.0.xx" that would come in but cause a crash before-- the crash you descibe, as well as a few others. And I see the eleven ".mmf" in "C:\Program Files\McAfee\McAfee VirusScan" that did same twice before. Odd-- various McAfee programs & McScan32.dll were mentioned in the crashes, BUT they were not changed (only .dat's/.mmf's were different). Anyhow, it took well by way of Superdat, & all seems well & good. As I bonus, it has now become tolerable to have McAfee's Auto-System Scan running, even now online. I don't know whether I must go for a Superdat every time now, or whether I may go back to the update button. Update: I can use the button. -- Thanks or Good Luck, There may be humor in this post, and, Naturally, you will not sue, should things get worse after this, PCR "Jamie" wrote in message ... | I have McAfee antivirus check on my PC, whne i try and | boot it up the virus check runs and scans for viruses, it | then says "checking memory for viruses........... is ok" | | after this it does nothing. | | Can anyone help??? |
