IRQL_NOT_LESS_OR_EQUAL hello there, my cpu used 2 be a 2400 but was recognised as a 1800 so after i changed the clock speed 2 133 then it was recognised as a 2400 but now after about 5 or 10min of doing somethings on the computer i get a blue screen of death errors each time they come different once come but mostly this one comes up IRQL_NOT_LESS_OR_EQUAL how can i fix this problem please help me.

You have lost a driver for the program mfewpak.sys or the system driver that is part of this program try this link.

not sure about the specific error, what are you doing at the time? IRQ is an interrupt request for the cpu. its basically like a take a number for the cpu's time. your keyboard usually gets firsat priority, but as for this specifically, im not sure, hopefully this info makes it easier for you to find a solution

IRQL errors are generally software/driver induced.
1st see if you can boot to the safe mode (F8 at boot) and get into windows.
If you can try a system restore to before the issue started.
If you can't get into windows, try Fn + power and run diagnostics on the system, you may have a bad hard drive.

there are 3 versions of that card, G1, g2 and G3, hardware generation. (G models ,not GV)
Guess G3 version:
xp 32 bit or 64b it is max OS for eternity, the virus magnet.

I read G3 manual for you.. easy. RTM

did you read, ddr caution 1 to 5 first. on DDR? and CPU, both.
both matters.
my guess is you failed to read PAGE, fully or not at all.
read it.
not told using, AGP video card, listed on QVL?
not told is AGP cocking tied or untied in bios page. same
if you overclock the memory the AGP card fails, if tied.
so rule #1 do not do that.


are you mucking with overclock settings, why not just set clock to DDR spec speed max and CPU speed max which ever is less.
Supports DDR400/333/266, 2 sticks max.
Quote caution 1
"FSB1066-CPU is supported only when you install AGP VGA card into AGP
slot. Besides, if you use a FSB1066-CPU on this motherboard, please
adopt a DDR400 CL2.5 memory module." 2GB max"
BIOS page, turn on memory timing by SPD (plug and play chip on sticks)
The bios will not know what CPU max is and then read he SPD chip and if equal it runs at that speed, or IF ether is lower spec. the speed is at the lower, do not overclock chips as that causes overheating and hard failures. but is you cash lost not mine and down time.
and even BSODs endless. (kids being kids)


the manuals on old mobo are clear on this and how.
no ram models told (sku models) nor how many or size ddr and if a matched pair is it MUST BE, (intel told you to !)
no CpU told, full model # of CPU not told. is this CPU 1066? rated , NOT TOLD.
so any easy answers wow hard.
learn to post using notepad MYbuild.txt FILE.
make a file and type all details of the this custom build.
then post that first so we can end guessing all that.
and get exact answers.
if GPU used, tell maker and model about 1/2 of all made fail. so...
cpu exact model not old (the lid of CPU all words there MATTER)
ddr size pair models.# (labels have P/n#)
set all ddr to auto. and do not overclock
use tied mode. (this scales fsb to gpu speed so can not fail)
Untied is overclocking mode, avoid that. (is dual clock settings)
learn to do this the safe way then later overclock (why) and break it later and then at that moment you know you did that, say next week?

and damage does happen.. doing that, costly too,.,


enable the SPD, this line means
SPD ( is the sticks Plug and Play WHO AM I CHIP) it in facts contains the full spec of the DDR inside SPD)
this act (SPD enabled)
sets the CPU to the speed max the paired DDR, to max allowed allowed (which ever is the lesser wins)
nothing works better and for longer. even a hot PC,

Maximum of 1 GB per slot.
Yes, you can buy DDR400, it will be underclocked by the motherboard to DDR266. If you want some extra performance you can go in the BIOS and lower the timings one unit.
Yes, they will work, but not very fast. They should be used only as a last option.

All Athlons were until a few months ago named on a power rating, not actual CPU speed rating. Since you didn't tell me the exact type of your processor i believe that it's the actual , normal speed of your CPU. But if it isn't then it's underclocked. To verify that go in the BIOS and see if the FSB is the correct value - 133MHz - sometimes it's at the default value of 100MHz. This can be changed from 2 locations:
1 - the JP4 jumper on the motherboard - 2-3 corresponds to 133MHz (of course you should change it only with the pc is disconnected from the mains)
2 - in BIOS go to Frequency/Voltage Control - CPU Host Clock and set it to 133.

usually blue screen errors are related with the ram memory issues or ...corrupt (bad status) Hdd, but in your case probably one of the coolers doesnt work and it is overheating and forced to shut down suddenly ..,solution is to verify the ram memory ...and check the bios for any temperature limitations...and best is to restore the optimal defaults settings ...( factory defaults ) ...and also try to reinstall the operating system cause it might just have so issues ....also ...try to remove and replace the ram unit in its slot ..to be sure that its all ok ...
there is whatever the possibility that overheating damaged the ram memory already ,.and in this case it should be replaced... but this case its rare ...and ram memory if its not touched by hand ...usually has a life time exploitation period...
so ....either unlimited the maximum cpu temp allowed ..from bios...or find a way to install extra cooler fan...and reinstall for to be sure its all Ok...

Normally this indicates some kind of resource conflict between device. Could be you just updated drivers for a device, or a new device was installed/used.
From the device manager you should be able to find out which devices have a resource conflict.
Other details on the driver irql not less or equal error might help you as well.

Hi, click on this MSI link which will open to the motherboard
K7T Turbo 2 (MS-6330 v5.0). Links for, Bios download, user manual & FAQ is listed at the top of the page in the blue in colored bar. http://www.msicomputer.com/product/detail_spec/K7Tturbo2.htm
You can run up to 1800 but it must be the AMD Athlon XP (Palomino, Socket A) up to 1800+

2500/256 celeron is 2.4 GHz. If there is a setting in bios, it should work. Most Intel motherboards do not allow you to change the clock speed as incressing clock speeds lead to system instability and less processor life. YOU WILL ALSO LOSE THE WARRANTY!!!
