Fatal Exception Error
Jen writes in with a troubleshooting question.
Question:I'd just finished up Online and my PC had been sitting idle for approx 20-30 minutes when the Display screen turned all different colors (Brick reds, black, yellows)w/ the font becoming a yellow color and is diff to read. I shut it down and now it won't boot at all - Even in Safe Mode. I get a Fatal Exception Error message - 0D @ 0147:0000BC9D, just when it looks like Windows might start. I attempted again to boot, this time w/ my Windows “Start up” Disk and ran a step by step confirmation run, and it said something about not being able to locate my RAM DRIVE! I'm assuming it's a Virus of some sort and I'd rather not have to take it to shop (yet again). Is the prognosis ominous or - Can my computer be saved?
Answer: There is always the chance that it can be a virus. You will need to run a scan to find out though. There is a virus called W32.Mydoom.F@mm that can affect your RAM drive. You can read about it here.
You can also try to restore a previous copy of the registry. To do so, do the following:
1. Reboot and hold the CTRL key down, until you get the boot menu. Choose Command Prompt Only. Or you can boot into Safe Mode and choose Command Prompt Only.
2. At the C:\> prompt type: scanreg /restore and press enter. Choose a backup with the word "Started" before it then press enter.
3. You should get a message that Windows has successfully restored the registry.
4. Reboot the computer to see if you can get back into Windows.
If none of these work you can try to reinstall Windows. If you have a backup of your data or don’t care if it gets erased I would highly recommend formatting the hard drive to make sure any viruses or corrupt files get cleaned out. For Windows 98 you will have to manually format the drive from the command prompt after booting with your boot disk.
At the command prompt type format c: /s where c: is your c drive and the /s switch Copies the operating system files IO.SYS, MSDOS.SYS, and COMMAND.COM from your system's startup drive to a newly formatted disk.
If you do not want to format your drive first you should be able to install Windows over your existing copy and keep your data and programs intact. Keep in mind there is a chance that something can go wrong! If a virus is present this will not necessarily fix the problem but may get you running long enough to back up your data.
To do this boot from your boot disk and pick the option to include your CD-ROM. Then switch the drive to you D drive by typing cd d: assuming d is your CD drive and then type setup and press enter to begin the installation process.
