Computer troubles-Help required!

Post

Sorry to bother you with non F1 related stuff, but I tought I could find some help here.

My cousin have some really strange problems with his PC. Unfortunately I can't give you the config right now, but I don't thing it matters that much (It's a shuttle thing, whith the specific little motherboard that fit in, probably fitted a P3, 1Go Ram DDR).

When the PC is switched on, there is nothing wrong with the BIOS page, and XP seems to boot normally, but it then run the session opener page with the window containing the session login and asking for the password. The first abnormal thing is that before the problem the session was logged automatically. But the real trouble is that by that moment, both the keyboard and the mouse are disabled! actually it looks just like if someone unplugged the mouse at that moment. I thought his mouse was KO, so I brang him another one which works, but it's the same thing. The keyboard works perfectly ok in the bios too.

The strange matter deepens when you boot XP in safe mode, with the exact same trouble occuring! It's like even the generic drivers used in safe mode aren't loaded for those damned mouse and keyboard (the screen is ok)... :?
Furthermore, I tried a system recuperation with the XP cd-rom, and after the disk loads several drivers and I pressed "R" so the system asked which session I tried to work on (there is only one so no wonder), I entered the password and validate (there is no password so no wonder too), here I did land on some prompt screen of this DOS emulation XP have , instead of the system running the recuperation... quite disturbing. :-k
All I could do there was run an extended check disk command (CHKDSK /p), giving no probant result at all, as the HDD seems phisically OK.

So, any idea?:idea: If anyone knows a way to help he's welcome! :wink:

It seems there are new viruses for XP lately, my father suffered a similar problem two weeks ago, and at work I did encounter less dangerous, but nontheless aggrivating things like a new addware called "Ircfast", which is a pain in the ass to remove.

Anyway thank you all guys for taking time to read this!

What I'll do, in order:

1. To disable the log in scren in Windows XP:

a- If you are in DOS mode, then continue to step b-. If you are in Windows mode, click Start and Run. If your mouse is not working, use Ctrl-Esc instead of clicking on Start, and use the arrows to highlight Run and press Enter instead of clicking on Run.
b- Type "Control Userpasswords2" and press Enter.
c- Uncheck the box for "Users must enter a user name and password to use this computer". If your mouse is not working, use the Tab key to move around the buttons and use the Space key to check/uncheck boxes.

In the improbable case you have to change the tab you are seeing (I mean, if for some reason you see the tab "Advanced Options" instead of the tab "Users"), use Ctrl-Tab to change between them.

d- Click Ok or use the Tab key until the OK button is highlighted and press Enter.

2. Check your antivirus software and how old are the virus files. If the PC has no antivirus, get one.

3. Check the disk using CHKDSK /F. I don't know what CHKDSK /P does. It's not in the list of valid switches for CHKDSK (when you type CHKDSK /? you can see the valid letters you can use).

4. Reinstall the mouse and keyboard drivers. Use the CD that came with your mouse (or with your PC, if the mouse came with it). Better yet, download the drivers from the manufacturer's site (do this in a "good" PC). Check the mouse model number in the tag you'll see in its back and try to download the specific drivers for this model.

5. Check if one of the pins of the mouse is bent and if it is, carefully, un-bent it. Same goes for the keyboard (I don't think so, the chances of bending both plugs are infinitesimal, but...). If the mouse is one of the older "roller ball" mouses, clean the rollers that hold the ball in place. Twist the circular plate that hold the ball in place to access the rollers.

6. If nothing works (or if this PC has no antivirus), bite the bullet (probably you will have to) and backup everything and reinstall Windows. You should do one of two things FIRST:

a. Make your cousin sign a legal affidavit, in the presence of your mother, his mother and preferably, most of your family and a couple of lawyers, stating clearly that if you damage the PC is his fault, videotape him signing and save the tape in a safe with the affidavit, OR

b. Send the PC to a technician before you mess so much with it that it really becomes damaged. :)

You could also recommend yor cousin to LEARN how to reinstall Windows, but I've seen entire families ripped apart on this subject, after going through the horror and despair of trying to, so I strongly recommend to get psychological advice before attempting that. If you're drunk, it could be easier and the nightmares will not be as recurrent.

If you go with option a., then read the Windows site about how to do this. And I mean it: read it. A bottle of whisky can become handy, as I said before.

The best you can do is to format the hard disk beforehand, which means you have been really careful about the backup: it's not only the videos, photos, .doc, .xls or other user files: it's the mail, the adress book, the faxes or any data that programs may have to use AND all the installation files downloaded from Internet that allow you to reinstall the downloaded software. Do you know something? Better make it TWO bottles of whiskey... :)

Install an antivirus before connecting to Internet and update the virus files as soon as you connect. This is something your cousin should do by himself, even if he has signed the the legal document: the chances of not backing everything up or of damaging the hard disk are considerable and it takes a lot of time.

This morning the electricity went off while I was defragmenting the HDD and I got the (0xc0000005). error message and reinstalled XP. Very unpleasant way to spend a Sunday.

CHKDSK/F - Means your F****D :lol:

CHKDSK/P - Means your P****D off :wink:

Those rabbits always make me smile Ray :D

Tried using a PS/2 keyboard instead of an USB one?

"disabled" or "unplugged"? Is the mouse LED on? things like Num Lock/Caps Lock lights? The symptoms you described could also mean the computer is frozen. Try pinging from another computer on the same LAN.

What if you try the other way around? Maybe the computer hangs when it's trying to auto-login. Force the user to do manual login, so that (hopefully) XP doesn't freeze on the login screen.

First of all, many thanks to you for answearing. I was right to think I can find help here.
By now I can't go any further because my cousin ain't at home untill wednesday, so the situation is stand-by at the moment.

-Ciro I'll try the Control Userpasswords2 command ASAP, after all the freeze occurs on the login page, maybe it is just related to it... As for the CHKDSK /p command, it's not like I learned that at school, it's the DOS itself that provide the information when you try a simple CHKDSK command (it says something like "try running an extended scan whith /p"), so I'll try /f too, thanks for the info. But I'm pretty sure the HDD is physically ok, from my experience it has never happened that a physically damaged HDD produce no strange sound while you operate a scan on it, every time I had a broken HDD it made some horrible noise that tells you something is wrong obiously. However, maybe just a few sectors containing parts of the kernel could be damaged, but I'm not sure it would lead to the descibed problem.

-Saribro It is a PS/2 keyboard already (and we tried another one to be sure), But both mouses we tried were USB ones. Do you think the BUS controlling the USB on the motherboard can be deteriorated? I mean, it's not like my cousin (the name's Fred, so I stop saying "my cousin" every now and then) tried to flash his BIOS, is it possible to cause dammage to a part of the MB just by catching viruses on the web?!

-joseff Everything seems to work normally untill the login page (during the boot, the mouse emits a brief red light as usual, the keyboard works in the BIOS menu and in the DOS as well, you can light on/off the Num lock/Caps lock lights, yes. But when we land on the login page, all is frozen, you can't light anything anymore, the mouse doesn't produce light anymore too. Exactly like if they were unplugged.
Also, saddly there are no other computer at Fred's home, and he has no fix IP, so it might be impossible to try to ping it.

I found that Windows has a page for "login freeze": symptoms are similar, it happens when your Autoexec file is encrypted. I'm not sure, as the instructions are for Windows 2000... :)

To solve it (if this is what is happening):

1. Start the Windows Recovery Console.
2. Type cd c:\, and then press ENTER.
3. Type rename autoexec.bat autoexec.old, and then press ENTER.
4. Type exit, and then press ENTER.

Check here for instructions to avoid Autoexec.bat being encrypted: http://support.microsoft.com/?kbid=269397

So you're pretty much saying "remove autoexec.bat".
Other ways to achieve the same effect:
- Boot from recovery floppies, delete the c:\autoexec.bat
- If you use FAT32 instead of NTFS (avoid like ralf schumacher at turn 1), boot from FreeDOS, then delete c:\autoexec.bat
- Boot from a linux recovery cd (like TRK/sysresccd), mount the drive, then delete autoexec.bat

Oh, the possibilities! I'd use FreeDOS though.

Well, I brought up the USB <-> PS/2 possibility because PS/2 is practically hardwired into any computer system (both hardware and software), whereas USB could get tricky, especially on older systems (P3 systems are older, yes :D). But that's obviously not it then.

For the moment I can't really think of anything that would both kill the auto-login and apparently hang the system. If something pops up, I'll let you know.

Oh, no, don't REMOVE it. RENAME it. :)

Most of what I have to offer is after the fact, but may help in the future.
First off, if your cousin tried to flash the BIOS, make sure it isn't corrupted. I would find the correct BIOS, and flash it myself.
There's a handy download that displays your system's hardware and software specs. It is safe, and free too. http://www.belarc.com
Additionally, to keep aware of my hard drive health, I use Speedfan, which displays temperatures as well as hard drive performance and health. http://www.almico.com/speedfan.php

Since this thread is almost dead, I hope you'll forgive me for hijacking it.

I've been having some problems with my computer. Based on what I had found out, the only way to fix the problem is to do a BIOS update. The problem is that every now and then, when I'm typing, I'll hit the SHIFT key and the computer will go berserk. I get some hieroglyphics, the CAPS automatically go on, most commands stop responding, etc. However, while I have found a way to live with this, a few months back, my CD-Drive disappeared. It is no longer recognized by the computer. Can't find it in My computer, Hardware profiles, nowhere. It seems to be working fine. When I pop in the CD, I can hear it spinning, the light is flashing etc.

I went to Toshiba's site and that is where I found out that one of the possible reasons for the disappearance of the CD-drive is an old BIOS version. The SHIFT key is definitely a BIOS problem...I've searched it on the internet, found many people who have had the exact same problems and have fixed it by updating their BIOS.

So, here is my problem. How do I do this update, without the CD-drive. According to the instructions on their site, I have to copy the files onto a CD or a floppy and during the power-up force the computer to switch to wherever the files are stored. Since it is a newer laptop, I don't have the A drive, and since the CD drive is no longer there, I'm wondering am I SOL? Will I have to bite the bullet and buy a new one, or is there a way around this?

Thanks

If the laptop can read USB natively, maybe you can import the data through a USB based external drive

Did you try entering bios? Check CD status in bios settings.
