A iso image is like a map of the cd you do not want to burn the iso image itself to the cd but use the method to burn a iso image using a iso burner.

I've downloaded deepburner and memtest86
What do I burn to the cd?
I see 4 files including a read me. I'm putting the files on cd and will try again to reboot
I'm sorry that I don't understand.
I burned 3 files to the cd, rebooted but it just booted normally.
I appreciate the help and patience but I'm lost as to what I'm supposed to do.

thanks for sticking with me on this.
I burned the iso image and see 2 files in a folder called "boot"
There is a file called boot and one called memtest.img
I rebooted the computer with the cd in the drive and nothing happened.
It booted normally.
What\s supposed to happen?

Have yoy tried to restore the system to an earlier date? The correspondence going on here, before elementry procedures are being performed, is strange to me.

If you read through microsoft literature you will see that the error you get can be caused by almost anything under the sun. I don't believe that the problem is with the hardware. You almost certailnly have a corrupted windows installation, a driver or an application. Microsoft admits that because of the large number of variables it is very possible that none of the methods offered will solve the problem.

This minidumps business can be extremely misleading and at best will give you 50% analysis with vague results which lead you to nowhere if not entirely out of course.

I agree skeptic lets stop from getting off track on the order of troubleshooting.

If a system restore does not work I would recommend uninstalling google desktop I have seen it do some weird things that early in the startup stage and it is still in beta last time I checked.

As of right now, it is working through a number of reboots.
Several days ago, I used last good configuration if that's what you mean.
The problems continued but haven't appeared in a couple days.
Would Google desktop suddenly cause problems after being installed for months?
I appreciate all the help.
Since it's working now, I'll see what happens and post back after uninstalling Desktop
Thank you

Restore and last good configuration are two different things. If the computer works well now don't do anything.

I'm back again and appreciate your help.
The machine worked famously for the past week until just a short while ago.
While my wife was on, it shut down. I couldn't get it to reboot in any manner.
After it sat for about a half hour, my son started it right up.
I wonder if some piece of hardware is failing.

If so, how do I get the machine to boot from the memtest cd?
That sounded like that was a logical step when we stopped.

Also, it was mentioned about a restore. How would I go about that?
Thank you
Larry

Would overheating cause this?
My son discovered the case was really warm and the intake fan was really dirty.
Blowing it out.

Overheating an cause lots of problems. Open the box and use a thin brush and a can of compressed air to clean the heatsink that sits on top of the cpu (the large mettalic circular or rectabgular body). Clean the interior of the computer with compressed air. Try to do this without moving parts or cables.

Download and install Everest (a link in my signature). Run it on Computer > sensor. Wait a few seconds until data shows up. Keep the program open and run your antivirus. After about 10 minutes see in Everst what temperatures you have for cpu, hard disk and motherboard.

Thanks, Skeptic.
Last evening we took the side panel off and blew the machine out a bit. Will grab some more air today.
Here are the temps:
Motherboard 113 F
CPU 100F
Drive 1 122
Drive 2 126

Temperatures look reasonable. I would like to see somewhat lower temperatures in the HD and motherboard so keep cleaning. If you can't improve it leave temps as they are.

Thanks.
Those are after we cleaned some and removed one side which is still off.
I grabbed some air today.
On my own computer, I leave the side off.
I may do that with this one.
