My computer restarts again and again

Couple of days ago I faced this terrible problem with my computer. While I was working, my computer used to restart again and again without giving any warning or error message. Earlier the frequency of restart was low, so I kept forcing my way thru the problem ie. simply working after it has restarted. But lately it had started restarting again and again. So I had to do something about the issue. Here is how I solved the problem.

First of all I disabled 'Automatic Restart' of computer in case of system failure. Here is a picorial step by step explanation of how to do it.

1) Right click on My Computer and click on properties.


2) Go to 'Advanced' Tab. At the bottom part of 'advanced' tab, you should be able to see 'Startup and Recovery' option. Click on the 'settings' button of 'startup and recovery' option.


3) Under the 'System Failure' option, uncheck the box 'Automatically restart'. Then click OK button.



This process stopped automatically restart of my computer in case of system failure, but the actual problem was still there. When I restarted my computer manually, after some time, I got a blue screen with error message. The message was "DRIVER_IRQL_NOT_LESS_OR_EQUAL". Though, there were so many other messages in greek, what I could understand was that the problem was because of file "IdechnDr.sys". I learned that this was a file required for an Intel application which was corrupted and was causing system failure. I had "Intel Application Accelerator" installed on my machine. Then I started my PC in safe mode, uninstalled this intel application and manually restarted the computer. Now my PC is working fine.
