No devices are displaying in device manager - Win98SE

Hello,

I have an issue with my computer not displaying devices in device manager after an unknown period of time. This prohibits me from using the internet, unless a web browser was open before device manager has stopped. The only way to get the list of devices to view again is by shutting down the PC.

A restart will not work either. When I attempt a windows restart, or a cold restart, the monitor goes into sleep mode, and the red pc led light remains lit and the PC hangs with no further processing.

All of these problems go away if I shut it down and then start again. I am then able to restart, get online, and see the devices in device manager for only a limited time which seems to be a couple hours maybe, but the time frame appears to be random.

What can I do to resolve this situation?

Regards,
Drumsticks

Hmmmm.....  Might be a heat issue. Check that all fans (intake, powersupply exhaust, CPU) are not clogged with dust. And that the airflow through the case is not blocked. Another thing to try is to take the case cover off and have a desk fan blow into it and see if it stops the problem.

Thank you for your post.

I had an overheating issue about two years ago and replaced and added a fan.  So now there are two fans in the box rather than one.  I checked the fans and they are running strong, and there is minimal to no dust inside the box, including in the fans or vents.  I frequently clean the PCs about once every two months since my learning experience with the overheating.

Generally, when I had overheating issues before and I would receive random errors.  However, this issue seems to be concise with the only random issue of when it decides to stop, which makes me believe that it probably isn't an overheating issue, although I could be wrong.  

I have taken the box off as you suggested, but I believe I've tried this about four or five months ago and there wasn't a resolution.

Do you or anyone have any other suggestions?

Regards,
Drumsticks

Not really. You might try: ( you do have a backup, right? )     : )

Description of the System File Checker Tool (Sfc.exe)
http://support.microsoft.com/default.aspx?scid=kb;en-us;185836

Start > Run sfc /scannow
From DOS: Go to C:\WINDOWS\SYSTEM and type SFC and choose Ckeck for missing/corrupt files

As a last thing to try:
Dirty Install of W98 (WinME)
You might have to install W98 over itself to fix it.  
Do Not FORMAT, Do NOT FDISK.  
Run the setup program from the CD or WINDOWS\OPTIONS\CABS or INSTALL folder.
This should save all of your settings and programs.
Also make sure you install to WINDOWS not WINDOWS001 ( or whatever ) when it asks where to install.

Although it sounds more like hardware.
I wonder if maybe your mobo or powersupply is starting to go flaky.

Coral47, Thanks!

System File Checker found a couple corrupt files, updated them, and I have no more issues now!

Thanks a bunch!
