My gateway ms2274 shows a bluescreen warrning say IRQL-less or-Equal and turn off. I restore it two times to the factory defaul restore t but it shows the same sign again and turned off.

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

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.

software booting files are corrupt,need to do system restore

Download a bluescreen viewer application in order to fetch the exact stop error, as this is critical to identifying and resolving any possible hardware related problem. Then copy and paste the exact message and info.

In regards to getting the "irql_not_less_or_equal" BSOD this can be related to several things. You could be having a driver problem or a hardware related problem. To know exactually what your problem is we need to look at the stop code you are getting as well. The link below will show you what number I need to see exactually where your problem is.

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...

it might be virus effect...........
reinstall os wiil solve the problem...........

Try this...on boot up hit F8 and select SAFE MODE and see if you can get in that way. Look on the control panel for add and remove programs...eliminate Uniblue from the program list. Reboot and you just may be fortunate.
Isn't it funny that the program that is messing up your machine is the one (for money) will fix it.
I still think the best way to update drivers is right from the manufacturer (ATI , nVidia, ASUS,)or the computer company (Dell-Gateway-HP) they all have driver updates for FREE in their Support area look for Drivers and Downloads. To contact their sites try the Company name and .com
I also think if things are running along just fine...don't update until performance suffers. Like your daddy told you...if it ain't busted, don't fix it.
hope this helps...good luck my friend

irql not less or equal sounds like a graphics driver problem. All you needed to do was boot up in safe mode and remove the gfx driver and the OS would have rebooted with the default driver and then you could have reinstalled it

Has memory been added to this laptop recently or any changes been made?

the irq error/bluescreen is mainly due hardware issue and most of the time in my experience, memory.

Re-seat your Ram, go into the bios and reset all back to factory defaults. Unplug all devices, as well.
