Please Please !!! - I've got no keyboard!

Things are spinning out of control now. Please tell me - I've got no keyboard. Doesn't a PC give an error on POST when there's no keyboard? I have an MS ergonomic PS/2 keyboard, and it was working today but now it isn't. It acts like it's not even connected. I swapped keyboards with one that's the old AT kind, with an AT --> PS/2 adaptor, and it's the same. However, I never did that before so I'm not 100% sure what's up. However, I sort of doubt that the PS/2 keyboard suddenly stopped working. I've been troubleshooting issues that suddenly started yesterday and I suspected my RAM or the PSU for reasons you can see below, where I quote another post just recently made (within the last 24 hours). I'm typing this at my second computer which is not internet connected. I'm going to copy this file to floppy and sneaker-net it to the lame PC and use my mouse to copy and paste text into THIS post. Is my motherboard dying?

I have another BIOS chip for this MB, an Epox 8K7A. Is it possible that swapping out the BIOS chip will fix this? I'd heard that my MB in the 1.0 rev. had a problem with the BIOS chips going bad, and I got Epox to send me one when I was getting a lot of BSODs.


As you can see in my quoted post below, I was planning on building a 2nd system (to replace my current 2nd system which is really old - AT system with 64 MB RAM and Cyrix P166+ CPU). So, I have a new MB, but I wasn't planning on making it my #1 system for a while. Wanted time and preparation and obviously it's a little hard to prepare a system for MB upgrade when it doesn't have keyboard support! I'm going to write down all the programs in Add/Remove programs so I know what I want to restore to a new system. I did a little research and figure that just swapping MBs is asking for trouble. Note: I'm multibooting OSs (in order of how much I use them):

Win2k (99%)
Win98SE (.5 %)
WinNT 4 SP6a (.5%)

As you can see in my post quoted below, I was having problems with MP3's sounding distorted for brief moments and quite occasionally and also noticed occasional jumping of my mouse. But the keyboard disappearing has me in crisis mode.

Thanks for any help. I'll check back here for posts. With mouse support, I can check the forums, but right now I can't answer except to type on my other system and sneaker-net.
My system was quite stable until the last day or so. First time I noticed a problem was TODAY. See below for my system specs. As seen in the specs, I multiboot, however my OS of choice and the only one I've used this week is Windows 2000 Pro, SP2. I made a couple of changes this week:

1. I swapped out my 2 sticks of Crucial 256 MB ECC PC2100 for a stick of PC2700 (Samsung chips on generic PCB) I bought for another machine that I will be assembling next week (MSI KT3 Ultra2 with XP 1700+). At first it worked fine. The vendor says on the receipt that I have one week to swap or get credit so I decided to test it in my current machine.

2. Yesterday I swapped out my cheap Enlight 300w PSU for a new Antec True430, again everything seemed to work fine except that I got an error the first time I booted from Motherboard Monitor. It was a tiny dialog saying "Privileged Instruction", and an OK button. After that one hiccup, no problems on reboot.

I actually slowed down my CPU yesterday from the overclocked 1.4 to 1.2, since my immediate goal is to quiet down this machine, hence the Antec PSU, which is supposed to be pretty quiet. I had experienced no problems running at 1.4.

Today, I booted the machine and played an MP3 file that I wanted to hear. It's always sounded fine and I've never had any issues with playing MP3s before with this machine. However, I noticed some nasty distortion around 10 seconds into the recording. Other MP3s were behaving similarly - weird distortion occasionally. Also sometimes little blips where it seemed to skip. Now this is probably a big clue: Twice I tried to download my email via my DSL connection, 5 messages. When it says downloading message 2 of 5, both times I was listening to this same MP3 and the sound would stop, resume after a few seconds for a second and stop again. Couldn't get into Task Manager. The whole system sort of locked up and I had to reset the machine. I've noticed that my MS Intellimouse USB optical mouse is jumping around sometimes, too. Usually it's stable and smooth. I ran memtest86 on the stick this morning, just the default tests, not the full set, and I got no errors with one pass through the tests.

Thanks for any help. Here's my system (except that I've swapped the PSU and RAM like I said, and I've slowed my T-bird down to 1.2 GHz):

Epox 8K7A motherboard
Athlon 1.2 GHz CPU running at 1.4, 133 CPU clock (At 1.2 now, though)
2 x 256 MB Crucial DDR ECC PC2100 266 RAM (512 MB Samsung PC2700 on generic PCB now)
MSI geforce2 Pro 64 MB DDR videocard
Hercules Game Theater XP soundcard
USR Model 2977 PCI hardware modem
Promise Ultra100 TX2 IDE controller
IBM Deskstar 60GXP 60 GB HDD ATA-100 IDE (Promise IDE1 Master) - Boot drive
IBM Deskstar 60GXP 40 GB HDD ATA-100 IDE (Promise IDE2 Master)
Pioneer 16x 106S Slot loader DVD IDE (Motherboard IDE1 Master)
Liteon 24102B CD-RW IDE 24x (Motherboard IDE2 Master)
Iomega Zip 250 IDE (Motherboard IDE2 slave)
Mitsumi Floppy
Enlight midtower case with 300 Watt PSU (swapped for Antec True430 PSU)
Nanao F2-17ex monitor
Windows 2000 Professional Service Pack 2 (OS of choice)
Windows 98SE
Windows NT4 SP6a
Run NAV 2001 in background

Does anyone have an idea what's wrong? I could swap the RAM and see if things clear up and if that doesn't work, the PSU. I'm NEVER going to buy generic RAM again, NEVER!

I found that I could not download that one email, the 2nd. Win2k would freeze. I couldn't stop the download or close the email client (Forte Agent). I could only reset! Since I multiboot I decided to try Win98SE. I couldn't get that message there either! However, I could end task on the Forte Agent. I sent an email to the guy who sent me the message asking him for help. I decided to try my Windows NT 4 SP6a, not expecting anything significantly different, but there appeared to be no problem and all my email messages downloaded fine, AFAIK.


My RAM timings are not overclocked and "Normal", not fast.

I swapped the RAM out with my previous RAM, but the problem persists - very occasional unmistakable distortion when playing known good MP3s. If I play the file again in the same section it doesn't necessarily distort in the same places, and if it does, not the same way, so it's not based solely in what's in the MP3 file. All I can think to do now is swap out the PSU I just installed Friday with my old one, a royal hassle, but I can't think of another stone to turn over. Any ideas appreciated.

Here's another clue for sure! I'm listening to a known good MP3 and it suddenly distorted for a 1/2 second. Sounded kind of like when you blow out and flap your lips, ya know what I mean? Well, my MS Intellimouse Explorer USB mouse cursor stuttered and strayed at exactly the same time as the distortion happened! What's going on? Thanks for any ideas.
 

Sound playback probs + mouse cursor acting up = nasty irq conflict (maybe)


I'd try resetting the cmos on that mobo. If it doesn't clear up your keyboard problem right away you may be in trouble...replace the mobo.

All this crossed my mind. Here's the state of things: I reset the CMOS, same problem. Like I said, I had a replacement BIOS chip and I replaced that and same problem! I figured the MB was screwed up. I was about to go out and get another keyboard to make sure it wasn't a bad keyboard and stopped and started pouring over the MB manual again. I immediately saw my problem - I'd been plugging the KB into the mouse PS/2 connector! OK, so now I had my keyboard back, but still had sound playback and jumping mouse problems. I posted in the soundcard newsgroups and a guy said he had similar problems and reverting to the previous version of the Promise IDE controller Windows driver resolved the problem. I'd had the idea to try that yesterday and today was going to try it and his saying that sealed the deal. When I first installed the version 2.00.0.34 of the Promise drivers I immediately had some nasty problems with my Intellimouse, especially in Windows NT 4 and relatively slight problems in Win2k. In NT4 it was major - It just went crazy. Inexplicably it disappeared after a couple of days! The Win2k mouse problems seemed to disappear when I put the mouse on the USB rather than PS/2 connection. Maybe there were MP3 problems then too but I just didn't notice. Reverting to 2.00.0.29 Promise Win2k driver seems to have completely resolved the problems which, YES, do seem like resource problems. I called Promise and talked with a technician (same guy I talked to a month ago when I first had problems with the driver) and he talked furiously, hardly letting me talk sometimes, about all the different possibilities, a bewildering array of contingencies and possibilities. He didn't seem to want to admit that their drivers are buggy. He did admit the possibility sometimes. Well, I wanted to give them a heads up. I can't spend the next 2 weeks researching resource allocation with my MB in Windows 2000, 98SE and NT4.
