My story starts with a new laptop, decided to install win 7...all went great for like a week then i received my first BSOD something about IRQL_NOT_LESS_OR_EQUAL then 11 other types of BSOD`s followed...
Gave up, and switched to win 8..all was good for like 5 days then same patern of BSOD`s happened



here is the win 7 colection of BDOS : Free Image Uploading, Image Sharing, & Photo Editing | tinyuploads

here is the win 8 colection of BDOS : Free Image Uploading, Image Sharing, & Photo Editing | tinyuploads

I will make and upload dump files soon.

IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: fffffffffffffff9, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000000, bitfield :
	bit 0 : value 0 = read operation, 1 = write operation
	bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: fffff802b66a7820, address which referenced memory

Install the latest windows update.

Perform this and post back the dumps

I use Avira antivirus and i have malwarebytes installed too

i opened the verifier, he asked me to restart pc..i did, i don`t see anything changed...it runs hidden or i did something wrong ?

I updated windows, had 8 updates to do, something about rapid storage, update for net framework 3.5 and a big pack update KB 2770917


do i need to wait for verifier to finish or some new BSOD to appear before i add here the new dump ?

uninstall avira antivirus..

Use windows defender instead.

Driver verifier tests the drivers and BSOD`s if it finds faulty drivers.

If it BSOD`s upload the new dumps

windows defender is the best for windows 8.

The dumps do not blame avira.

But this might be behind to BSOD.

It just tells some driver is causing the fault.
By executing driver verifier we can find out which driver is causing the fault

ok got a new BSOD called PFN list corrupt

do i use the SF tool or just upload the minidumps ?


Also everytime after BSOD for like 5-10 minutes i cannot open my computer anymore, i keep geting a netoskrnl error ( something like that )

i`m looking forward for an idea on this ^...why closing my pc from button and waiting some time helps clear the error (closing from button and opening it without waiting some time still brings netoskrnl.exe error )

edit2: after a BSOD some " windows automate repair " pops up and i get the following

ntoskrnl.exe with codes 0xc 098, 0428, 0221 and 01
and winload oxc 01
5 minutes later i got a wdf01000.exe 0xc 0221

Imagine it like this, i open laptop, goes into repair...get the error, ctrl+alt+delete restart...again repair...new error etc :D

leaving it 10 minutes for the " autorepair to dissapear at boot makes my pc usefull again "

do this overnight.

errors might be detected after 8 passes.

The reason i have asked you is that one of your dump blames mem corruption. This can be caused by bad driver also

before installing windows 8 i had it run for 2 hours ( 3-4 passes ) from a PartedMagic USB stick and found no errors
+ my computer was checked for hard-drive, video board and memory and again was told no problems found.


only thing it has is a Hard Drive that runs a little hotter than what i`m used too, but their site specifies 60 degrees as maximum temperature which i haven`t yet reached ( tho was close, 58 degrees in skyrim )

it is a laptop, less than 30 days old. I have no idea about it`s cooling system nor do i wish to open it in any way to break the 2 year guarantee

If i cannot fix it or discover it`s hardware related i`ll send it back, but i need reason for that.

yes updated them.

what can cause the netoskrnl.exe error at startup ? Allways after a BSOD but sometimes even after a simple restart of computer.
