Windows 7: BSOD IRQL_NOT_LESS_OR_EQUAL and random freezes

Slartybart, I'm not familiar with Magic ISO, if it uses SPTD I have a tool to get rid of it. Programs like Dameon tools and Alcohol 120 use it and it is almost impossible to get rid of. It is an SCSI pass through direct which will often cause trouble. 7 ZIP is a very good program, I use it quite often. I'm not sure, but I believe ImgBurn will do about the same as Magic ISO.

I actually use 7zip as my zip/rar manager. But I didn't know you can use it for iso as well! Thank you for the great tip, Slartybart. I will look through the list of free great programs, thank you for the link.

You're most welcome, Nisym.

I think I mentioned this before, but I should re-empathize it.

Since you're battling an issue with BSOds, do not install anything new until you reach a resolution. Uninstalling removes things from the equation and helps trouble shoot the original issue. Installing new software while your machine is still experiencing the issue might muddy the water by adding a new driver or software.

So keep the system as it is, sans removing suspect or identified software, and run for a while after each change. How long? Until another new BSOD or no new BSODs. This might take some time because it isn't clear what is causing the issue. By process of elimination, the culprit might be identified.

@essenbe: Imgburn - that's the pgm I couldn't think of - thanks.

I don't know about SPTD and MagicISO either. I recall there is a way to spot SPTD though, but I don't recall where to look. It might be worthwhile to run the tool anyway, unless there is a caveat.

It is usually associated with Dameon tools and Alcohol 120, but it is just a SPTD remover and won't hurt. The tool, as I understand it, won't work unless you have SPTD in the system.

Daemon Tools, Alcohol 120% and Power Archiver Pro uses SCSI Pass Through Direct (SPTD), which is a well known cause of BSOD's.

1. Uninstall Daemon Tools.
2. Download the SPTD standalone installer and follow these steps:
- Double click the executable to open it
- Click the button shown below



If the button it is grayed out, as shown in the image, there is no more SPTD installation on your system, and you can just close the window.

MagicISO or MagicDisc does not use SPTD. But still it is equally problematic, because of the MagicISO SCSI Host Controller, mcdbus.sys.

I would never suggest to use a disc emaluator of any sort. It emaluates hardware based on software. So it needs to start before windows; and problems occur.

My take is to use either 7-zip (free) or winrar (with a little cost) to manage the iso or any other sort of disc images. Those two can extract them all, so the basic job is equally done. You may miss the autorun at most, and nothing else.

That's what I remember - the standalone uninstaller. A picture really is worth a thousand words.

Just a note on the list items. I'm not sure Nisym has Deamon tools installed, but if it is it should be removed.

@Arc: Thanks for the information re: SPTD & MagicISO. I agree completely on NOT using drive emulators.

I don't have Daemon tools installed. Honestly, I don't even know what it is, sounds like the name of a malware of some sort, hehe.

I will keep that in mind, Slartybart, no installations for awhile.

Daemon Tools is like MagicISO, and it does sound demonic - Unix uses the term a lot for behind the scene services.

You're doing a great job Nisym, it's a pleasure helping you solve the issue.

Bill is easier to type than Slartybart - and you don't get the spelling "error" highlights if you use IE 10 or 11

Bill is it? Well thank you, Bill, for your patience and help, it is most appreciated.

At this point, I think rather than looking for a MagicISO replacement, I'll just use 7zip should the occasion arises.

I actually don't mind those spelling error highlights. I'd like to think that I'm a much more proficient typist thanks to those highlights.

Oh, and I'm Olanka.
