98 Update causes Monitor to go dark

JF, it sounds like a power management problem, but did you disable your antivirus before installing SE? If you didn't, some of the updated files may not have loaded.

First, go into control panel, power management and change all of the power saving features to none and then test the system. If it works, boot into the Bios setup and disable power management in the bios, boot through to Win98 and then re-enable power saving in control panel, power management and test it again.

Dennis!  I followed your instructions but the power management propoerties (Control Panel) has only two screens: the first gives Power Schemes. Mine is always on. At the bottom of thisscreen: Turn off Monitor 15 min. and Turn off disk 1 Hour.  The second screen {Advanced] has a sentence select your propoerties (BUT there is NOTHING to select.  Then there is a item to check if you want the icon on the desk top.  In short: There are NO options in the advanced screen. The phrase power saving nevers appears in either of the only two available screens!! Thanks   Joe

Go back to Power management properties and where you see ALWAYS ON ,click the arrowhead at the end of that box. Set it to home/office and you can now change all the settings to NEVER.

Nick, posting someone elses comments as your answer is about as unprofessional as it gets! You'll never become a MCSE that way, IT professionals will shred you like cheap toilet paper, me included!

Joe, boot into the Bios setup for the motherboard and disable power management.

Next, go into control panel, power management.

Change Power Schemes to always on.
Change System Standby to Never
Change Turn Off monitor to 15 minutes
Change Turn off Hard disk to Never

Test the machine and let me know!

The solution proposed worked perfectly!  I was very impressed with the fantastic turnaround.  My "ghurus" here had no idea about what to do.  I was grimly prepared to clean my drive and restore from a backup.  This means I avoid that horror and retain WIN98 II.  Your Web Site is now prominently displayed in my Favorites but I won't need to look it up. Thanks again for your valuable help.  I appreciate it.     Joe Gross

Joe, which solution did you follow, mine or the answer you accepted?

I changed the power saving times to Never.  I restarted and have been working at the computer since. I did not change the CMOS. It seemed to me that both replies were correct but I was told that Vismag was the accepted answer although I did reply to Dennis (Dew Associates)first.   Perhaps the point total should be split between the two. I certainly hope that I am not creating a controversy.   Joe
