[RESOLVED] Win98 SE lock-up

I've recently installed Win98 SE on a
P3 450, ASUS P2B-LS Motherboard, with 128
MB SDRAM. Hard-drive is a IBM SCSI 8GB.

Windows boots up nicely, but locks-up
randomly. I mean I can just leave it running,
without doing anything, and it'll eventually
lock-up (the time interval is between 5 min
and 6 hours)

When this happens, the mouse ceases to respond, CTRL-ALT-DEL doesn't do anything
and you have to reboot.

Everything is well configured, i.e. no exclamation marks in the device manager.

I've reinstalled a couple of times, both Windows and all drivers I could think of, but I have the same problem. BTW, if I use Win95, I have no problems.

I'd appreciate any suggestions.

Disable all Advanced Power Management in Control Panel

try downloading the lates bios from asus they update often

Sounds like overheating, I suppose the cpu cooler fan is running?


------------------

In my humble opinion, I would disable Task Manager permanently. I have seen this cause more problems than any other one thing in windows.

Are we havin' fun yet?

You didn't list a video card in your description but I will tell you this. If you are using a Diamond 550 under Win98se and a Logitech mouse I have seen this same issue several times before. The remedy is to switch to Nvidia 3.53 drivers and it corrects this issue.

------------------
I wish I knew what I was doing.

Diamond 550 prob with Win98 SE is the conflict between the COMCTL32.DLL ( within IE5 ) and the version that Diamond used. If you install the 255 release of the Viper V550 drivers this prob is solved. I have found personally that Nvidia ref drivers don't perform as well as the Diamond originals.

why are our jobs so interesting??????

As said before, what video card do you have. In my home computer I had that problem with an Adaptec 2940U2W card and a Diamond Stealth III Video card. Diamond has posted an updated driver to fix conflicts with SCSI Cards.

I have a similar problem... with Win 98 though....


Creative Labs Graphics Blaster Exxtreme Vido Card
400 MHz
64MB RAM
6GB Hard-drive

Our seems to "stall" when I try to perform more than one thing at a time.... have to CTRL-ALT-DELETE and sometimes it works, but usually have to also reboot. Have tried to reformat the hard-drive and reinstall, but has not resolved the problem...I still have to install the audio drivers, but this was occuring prior to the audio being gone.

Look at the scsi driver in win98se. I know it should work but, it is not a common problem. it could be video, but video does not cause this many problems. I have seen other related problems with ASUS scsi drivers before. I do agree that you should check for a bios update for the MB.

Plese let us know for sure if it turns out to be anything else.

I've seen this Problem on other PC's incuding
My own running the K63 series chips, they run very hot, with my K63 450 I have to run the PC with the case cover off and I have no problems, I tried putting extra case fans in the case one in front to draw air in, a large fan and heat sink on the chip and one in a slot in back to draw the air out and this slowed the time between lock up's but did not eliminate them by leaving the case open it runs fine

when I see this problem it's usually heat and usually from the video card. I have had great results using those fans that are flat and have a bracket so you can screw them into an empty slot and face the fan part right in front of the video card. They suck the heat right out of the case. Its worked every time so far where heat seemed a problem, and since your lock-ups are so random seems likely. You could try a diff power supply too in case your might be acting up.
