strange problem.... solutions?

Hey, Guys, i have been trying to help out my friend with his comp.

here are the pertinent specs:

he has an HP pavilion 6635 (celeron 530 socket 370 on intel 810 chipset, i believe, but could be wrong)
128 MB (crucial) and 64 MB (infineon) sticks of Ram
cordless usb wheel mouse (intel, maybe?)
ps2 mouse (yes, he uses this one when recharging the batteries)
ps2 keyboard
usb intel web cam w/ mic
running w2kpro
not sure of bios revision, but one of the older ones, came with his comp i think, but not sure how old his comp is.

and here is the problem:

I have helped him recently put in the 128 MB stick of crucial ram, as well as the usb intel web cam.

at first he was having problems posting, which led me to believe the ram was bad. but i put it in my machine and ran memtest86 (v2.8, i believe, the newest version) and it went through the test fine, all (11?) tests, and passed, without any errors.

he has had his usb cordless mouse for around five months, so i assume this is not the problem.

but we have been having problems with the web cam. it is difficult to describe the entire situation, but i will try.

basically, it will install "ok" and upon reboot, will operate correctly. but after that, sometimes more rebooting, w2kpro will not recognize the camera as a camera, and will require full uninstallation of the drivers and reinstallation of the software and drivers. I tried to just direct windows to the winnt/system32 and winnt/system32/drivers folders, but windows would not recognize anything installed in those categories as pertinent to the camera itself.

he would have random things happen to the comp with all different configurations.

for example:

sometimes, the computer would say that the keyboard has a stuck key (when nothing was being pressed) but then would boot up to windows, but then the problem with the web cam would occur.

sometimes it wouldn't even post, and would require a few boot ups to get through posting and into windows.

sometimes the ps2 mouse wouldn't work, sometimes the keyboard wouldn't work.
when the usb mouse was connected, sometimes it wouldn't work as well.

all these "sometimes" are with and without the usb web cam and usb mouse connected. these different configurations were also with the ram in different spots, with only one ram stick or the other... and these random things would still happen. sometimes it would boot up perfectly, but upon reboot, it would just be entirely messed up.

i thought maybe it could be IRQ conflicts with his devices, so i told him to disable game port, serial, MIDI...
but still random problems, the same random problems: stuck key, mouse not working, web cam not being recognized...

before the ram and web cam were in, he was fine. but now even with both of them out, he is still having problems...

i have run out of ideas and solutions to his problem(s).

do ANY of you guys know what could be causing the problems? i am open to any solutions, and will pass on any ideas to him.

TIA,

-Mel

Ram issue first:

Just because you tested it doesn't mean his board doesn't have issues with it. He very well could. He also could have issues with 2 different type of ram working together...a whole host of issues...

Web cam:

Sounds like it is just one of the incompatabilities that creep up...Does the wevbcam have specific win2k drivers???

hm, i had thought i had compensated for any ram issues by trying a host of configurations with the ram sticks, but maybe... both infineon and micron are on the tested list on the hp web site, i know crucial is not exactly micron... but i would assume very close.

and as for the web cam, yes, it had exact drivers, even in four different languages.

thanks,

btw, do you still think it's the ram?

The problems with the sometimes not posting may be ram related...However I think the majority of the other issues are the webcam, definitely...

Have you downloaded all the patches for win2k? There may have been some usb support updates. I am not sure though. Usb issues can cause a lot of the issues you are talking about.

If webcam is completely removed..drivers, software, and hardware...do you still have any stability issues???

i believe even with the peripheral devices not connected, there would be these random problems, at least that is what i remember.

he has not updated much of the operating system, which i have encouraged him to do... heh...

but i don't think such severe problems could stem from not implementing an update.

-Mel

edit: but most (all, i think) of the problems are before the operating system is even started. posting issues, keyboard, but then after that i guess with the mouse and keyboard not being able to be used. hmmmm, i am just stumped.

Check around for it though...There was issues with usb devices that really only showed up with multiple usb devices running and when usb optical mouses were used...patch fixed a lot of the issues...

I am not sure in what OS it was since I haven't had any issues in winme, but then again my usb devices are printer, scanner, and dig camera...never seem to have multiples running...


Once you get system to post have it run memtest on the ram in his board....

hm, i see, will inform him, but he is not using an optical mouse, but a wireless one with the ball, with a wheel.

yea, initially i had him run memtest on his comp, but it wouldn't even load properly - that's what made me think it was bad ram.

but then it ran through the tests fine on my comp. i will tell him to run the memtest86 program again, and see if it works.


but if it doesn't, does that just mean that there is a conflict with the ram even though it goes fine sometimes?

If memtest finds errors that could be part of the problems...

If memtest doesn't find any errors he may do 2 things: 1 he can try to get his hand on a matching stick (128mb) of the same type as used by the first stick of ram he had. Try to match them as to brand and avoid possible compatabilities. 2: he can leave it alone and assume it is something else...


I think memtest will find errors if it is a compataility issue anyways...IMO

Do a search of over the past 45-60 days in these forums for usb problems in win2k and see what they say....
