Blue screen Driver IRQL not less or equal

"IdeChnDr.sys"
This is a driver file, having to do with the "Intel Application Accelerator."
If you know you have this file, I'd delete it ASAP, found within:
C:\Windows\System32\drivers

Hello my friend!

I got same message, and it was fail in HD. I Had seagate BC.

Good Luck! Jarmo

i have the same blue screen and error messages but my tech info says
stop 0x000000D1 (ox6f524557,0x00000002 0x0000000,0xf900ecd9
Rt 2500.sys address f900ecd9 base at f8ff8000 date stamp 42675c99


I have tried several registry fixes such as reg cure but to no avail and it will let me boot up and then start up for a few minutes and then crash

Sorry i forgot to add any help would be totally appreciated

Looks like this is related to Asus Mobos, another recent poster with Asus mobo has the same problem as well. DOnt know about the rest of you guys...Asus or not?

May be doing a repair install helps, as the problem is related to drivers in the Windows Folder. Repair install may solve the problem at hand.

I dont know that, can i use any other private sites link here. so i just copingy the matter that i had just read from a site.


SOLUTION:

The IDECHNDR.SYS is a driver associated with the Intel application accelerator programme. Apparently, this is a known issue.

Uninstall the programme and see if that helps.


There have been quite a few cases of the Intel application accelerator causing problems. In most cases, uninstalling the programme has helped.

Even Intel says it`s not necessarily required.

If external links are not allowed here kindly remove it from the post

Less or not equal?-

This can be very well associated with the Intel application accelerator, but it sound to me that you have uncompilable RAM or your RAM has gone bad.

I suggest you download memtest 86+ and run all the mem tests, if you see any errors then one of your RAM sticks is failing.

This is a known issue related to RAM.

Here is a post, it might help.
