Helping people with computers... one answer at a time.

VxD errors are specific to Windows 95, 98, and ME. It's hard to determine exactly what causes them, but there are a couple areas to look at.

I've used Spybot, etc. to get rid of a number of problems. However, my system performance (and I have cable) is still extremely slow. I receive constant blue screens that relate to error messages in VxD. Most of the time it allows you to press Enter and continue. Could you please lend some assistance with these numerous errors in VxD blue screen error messages?

A "VxD" is a "Virtual Device Driver", so named for the ".vxd" file extension they're given. They're unique to the Windows 9x family - Windows 95, 98, and Me - and provide the software that allows Windows to communicate with and control the computer's hardware.

So what do you do when a VxD reports an error?

Without more information, just "VxD errors" by itself is impossible to diagnose. As I've mentioned, VxD's are all about hardware and errors are typically due to driver issues. If there's particular scenario where errors happens that involves a particular piece of hardware, or perhaps even if not, my first step would be to check for updated hardware drivers. A visit to Windows Update might also be a good idea. This page on may also help with specific issues.

It might also be a hardware problem. Quite often a system about to die will start to suffer from these types of problems. It's hard to say exactly what it is until your system actually kicks the bucket. You might test the memory with this tool - though it is kinda techie.

It's worth noting that this is one of the areas that has improved significantly in Windows XP. Windows 9x was much more vulnerable to device driver problems as well as application bugs. In short, Windows 9x blue screens more often than Windows XP.

Like the rest, I too suffered from pesky VXD errors, and I've seen it too happen in my client where I work as a part-time programmer. This VXD error really pissed me out, like a heckler perpetually would pop out whenever I use my Pc. I used Win98se then. But now, I've upgraded to XP. Though there are no more VXD errors to talk about, there are now checksum errors that I would encounter from time to time.

I run Windows 98 SE. Right now my startup only runs upto driver loading (I suspect) because something is wrong with VXD (as the screen displays - failed to initialize VXD restart.) and I need to restart my computer. But I get the same error each time.
What I did: Scandisk /autofix /surface
As the surface scan started, I notice there are a couple of sectors marked as bad (I suspect this is where the VXD file resides). I finished the scan, but when starting--I still get the same error.
what should I do next?
1. Can I re-install my win98se over the current one to fix it and if so -- will I be able to retain all my previous application and configurations?
2. Will Norton Disc Doctor help solve the problem?
Thank you!

Actually both approaches sound valid. You should be able to do a "repair" install of Windows 98. This article touches on that:

I get the error "A fatal exception 06 has occurred at 0028:C0047C94 in VXD VFAT(01) + 00005A84" the moment I double click Warez P2P. My PC hangs down and I need to restart my PC and in the process I can only open it after several such messages and keep switching on and off several times. I use Win 98SE. Please help me to solve this problem.

I had this same error message on my computer. I found the problem. The CPU was overheated, because the IDE cable that went to the CDROM was pressed against the processor's fan. It couldn't cool the processor. The computer worked for 30 minutes, and then it would freeze for no reason. Then I had to wait an hour and turn the computer back on. I tried to reinstall Windows, but every time I tried to reinstall, it froze. Earlier when I replaced the power supply, I did not see that the cables were jammed behind the power supply pushing against the processor. PROBLEM SOLVED. Now, this was my problem, but this error message can occur for many other reasons such as defective memory, defective motherboard, defective hard drive, etc...

My problem first started when i switched pc's location from one room to another and when I rebooted i got "mouse not detected" on boot up with my normal backround pic b4 all the icons load on the screen,so i reboot and let it scan disk,when it does surface scan and gets 99% done (3 lil boxes away from the end of scan) it gives me a message that there is errors (on a prompt box ) so i click ok or contine then another prompt box comes up saying its gona collect data and save it to a good part of the drive but never does anything..i waited and waited over a day and nothing(also the prompt box has a "stop" button )then the screen goes black and even pushing the space bar doesnt do anything for it,and now if i try to let it continue to load all the way i cant even use the keyboard now ,which in the first dozen boot ups i could!also blue screens with the oem and vxd error remarks...let me know if you need the exact error message and error #.. (win 98se) ~John
