Windows 7 x64 blue screened every few minutes with error code 124, but worked in secure mode.(EDIT: safe mode) I tried reinstalling windows, which didn't work, so i tried to install various Linux systems which also didn't work. the computer freezes most times on installing or gives a detailed erro rmsg like this one (its always the same with CPU bank stuff):    Super detailed system specs:   The only thing that works is a 2013 version of parted magic, a "repair" linux distro. so we could do all sorts of checks!  btw, disabling cpu cores is not possible in bios.  is this just a simple "cpu is damaged" problem? i found the same cpu for 10€ on ebay  EDit:   @secure mode  its actually called safe mode (sry english is not my first language)  @resetting your BIOS settings to defaults?  yes, i tried that, and enabling disabling different features in bios  @other routine checks like running a memory checking tool  i did alot of test from this disc:  i did different memory checks, cpu tests and hdd checks. nothing interesting came out.  @cpufan  idk how to check this as it is a laptop. i can hear a fan and it dosnt crash or burn during "system stability tester" from parted magic. (wich is a program to stresstest cpu by calculating millions of digits of pi) sensors temperature is at 60°C during this stresstest, (65°C max only hit shortly) so i guess its working  @mobo  ill open it up and edit the post (the mainboard has been swapped by lenovo service)
I've been having problems with a blue-screening Laptop (BCCode 124), and I've been trying to track down whats causing it. (It bluescreened randomly after 5-30 minutes of running in win7). It worked in safe mode. I tried reinstalling Windows, which didn't work, so I tried to install various Linux systems which also didn't work.  The only thing working right now is the parted magic version of the ultimate boot cd.(Its a repair linux distro that runs live from ram)  I had the idea to run a bunch of stability tests to try and isolate the faulty component(s), and I wanted some input on my results.  I did different cpu stresstests for different times. No problem (temerature ~60°C sometimes peaks at 65)  I ran memtest with no errors many times.  I also did a GPU check wich is included in the ultimate boot cd - parted magic distro - no problem.  I also checked the hard drive with different tools included in parted magic - no problem there too.  Every linux system I try to install crashes when I try to install it. (It either freezes with no error (rarely happens) or I get something like this shortly after I tell it to install (tried about 20 different distros): [*] 3 photos in the dropbox  Trying to isntall windows 7 just gives a generic "there was a problem" / "an error has occured" screen with no further information.  The laptop is a Lenovo B570. Here are the detailed system specs (the ram is a 4GB kingston now) [*] the hardinfo file in the dropbox  I have 3 crashdumps from Windows wich I can not open. (visual studio says it cant open old crashdump files) [*] 3 dumps in the dropbox  Can you help me to track down the cause?

modify specific column with sed or awk I have a CSV file that looks like this:  qw12er,foo,0 bn5mgh rt8yp,foo,10 gh78jk bn852mv,foo,852 78ghjkh tgbr,foo,10 ujmyhn wsx2d,foo,0000 ui52ohn tgbr,foo,7418529 ujmyhn ikl896o,foo,22 wsxdc52   I want to modify the 3rd column and remove all numbers and space from the beginning of the 3rd column.  Then output would be as follows:  qw12er,foo,bn5mgh rt8yp,foo,gh78jk bn852mv,foo,78ghjkh tgbr,foo,ujmyhn wsx2d,foo,ui52ohn tgbr,foo,ujmyhn ikl896o,foo,wsxdc52 Why is Compactification restricted to Toroids, Calabi-Yau et al? Story of lost tech but magic manifests I'm looking for this novel (or maybe a series of books?). I remember that technology began failing all over the world. Some people began transforming into different types of mythical creatures, like sprites, demons, etc. There was a band of about four travelers that were trying to make it to Chicago, since that seemed to be at the center of the issue. The story line frequently shifted the point of view in each new chapter. I vaguely recall a final battle in Chicago with an enormous and powerful demon creature. I think this demon used to be a corporate lawyer or big business guy before his transformation. I believe I read this in the early/mid 2000s, and was likely published around that time because of the types of tech used and failing in the story. Although it bears some surface similarity to the TV show, Revolution, they aren’t comparable in plot or characters. Live CD asks for a username and password Should edits with only minor code improvements be accepted. As an example, I'm reviewing an edit that changes all double quotes to single quotes and renames a variable in some javascript. With the exception of the variable rename (which is not entirely necessary), the edit is frivolous. Should I accept on the merits of a debatable variable name change? Why aren’t my villagers breeding? I’ve got one villager up 7 blocks surrounded with 6 doors. On ground level I have villagers who are supposed to breed. They are willing, their inventories are full of potatoes, and I’ve been sitting here for hours.  Hearts are popping up above their heads but nothing happens. I am playing on Xbox One. Computer doesn't boot up, shows PXE error and/or "operating system not found", "no bootable device", "insert boot media", or other similar error How do I disable the screensaver/lock? When I'm watching a film in Mythtv the screen turns to black every 10 - 15 mins and I have to log back into Ubuntu. Very annoying!  How do I disable the black screen / screensaver / logout in Unity?  There no longer seems to be any options to turn the screen saver off as there were in Ubuntu prior to Unity. EL proposals / autocomplete / code assist in Facelets with Eclipse Anyone know if R has quote-like operators like Perl's qw() for generating character vectors? A closed form for a triple integral with sines and cosines I read the following dev email  and when i read this part:  Note that this does not completely remove the ability for extensions (e.g. Dropbox) to add emblems programmatically by using the libnautilus-extension library, just the user-added emblems from the properties dialog/emblems sidebar.   There is ability to bring emblems programmatically. So, How can i use libnautilus-extension library to add some emblems like Dropbox does? Or is there any tweak tool for this? What does it mean to instantiate a trait? Remember window locations when docked and undocked I find this beyond frustrating.  I have two extra screens on my laptop at work. I take my laptop and go home, with no extra screens connected. I come back, dock the laptop, and the windows need to be rearranged again.  Is there a way to get windows (or a utility) to keep track of the overall screen configuration (#, size, resolution), and remember where windows were placed, so when the screen configuration matches again, it puts applications BACK where they were? iPad won't turn on after a complete battery drain My iPad mini retina is out of warranty,  I forgot to plug in my iPad after the critical battery warning and it went some minutes following the warning. I was not worried because same thing had happened a few times before and iPad was perfectly okay after charging it. However, this time I remember seeing a flash of blue screen immediately after it went black. Then, I plugged it in an waited for a while and tried starting it. Ever since, it fails to start hanging on the apple logo with white background screen.   I tried to connect to my Mac but nothing showed up in iTunes. I am worried now. Can I troubleshoot this or is it broken and needing repair? $\Bbb{Z}_{26} \rtimes_{\alpha} \Bbb{Z}_{5} \cong \Bbb{Z}_{26} \times \Bbb{Z}_{5}$ as groups. I am running Ubuntu 15.10 with Gnome DE.  I installed KDE plasma to try it out but sudo apt-get upgrade started giving me errors so I ppa-purged the kde ppa and removed kubuntu desktop with the terminal in Gnome.

I tried sudo apt-get remove kde-telepathy-minimal to remove the package which gives me this error:    The following packages have unmet dependencies: kde-telepathy : Depends: kde-telepathy-minimal   Attempting to remove 'kde-telepathy' gives me the original error.
