Solving windows 7 ntoskrnl.exe blue screen of death

Two cases concerning memory corruption, probably driver related, and one case of possibly corrupt system files.


Firstly, you should test RAM with memtest.You can use built in memory test application http://www.howtogeek.com/howto/wind...y-using-windows-vista-memory-diagnostic-tool/
You should do at least 7 full passes. Post the test results here.


Secondly, insert your windows installation DVD, boot from it (usually, you can enter the boot menu by pressing the F12 key just after starting your PC and choosing the DVD drive on the list) and on the first screen choose language.


On the second screen click "repair your computer", in the dialog that appears click next (here note the drive specified on the right, it will probably be D: ) and finally choose "command prompt".
Once at the command prompt, input


Code:
chkdsk d: /r /f 


Allow it to complete the scan and post the results here.


Lastly, once back at the command prompt, input this
Code:


sfc /SCANNOW /OFFBOOTDIR=c:\ /OFFWINDIR=d:\Windows


Typically, c: is the boot partition, d should be the windows partition, from the recovery console perspective.


If unsure, you can input
Code:
diskpart
list volume
which will show you the list of all available partitions.

Change the hostname without logging out or restart in linux

echo “newhostname” > /proc/sys/kernel/hostname 


and you are done!!!

Enable EPL on RHEL compatible distros such as CentOS/Scientific Linux

How can I install the packages from the EPEL software repository?

There are repository rpm packages for RHEL5 and RHEL6. The repository package installs the repo details on your local system for yum or up2date to use. Then you can install packages with your usual method, and the EPEL repository is included.

For EL5:

su -c 'rpm -Uvh http://download.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm'
...
su -c 'yum install foo'

For EL6:

su -c 'rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-7.noarch.rpm'
...
su -c 'yum install foo'


then install the rpms from rpmfusion and you will be fine
