Internet tips & tricks world

if you are experiencing random BSOD Memory errors without change much on you system it is worth to check following thing before:

1. Use WinDBG to find out any issues with drivers (!analyze -v – should give you the driver name)
   • If you see different program or drivers, follow below. Otherwise remove / update the driver to check if the BSOD stops.
2. Check Cooling (Thermal paste) on CPU
   • Check with Core Temp program or maybe in bios.
   • Intel CPU’s should have approx 30-40° C while AMD little more like 60° ? Not sure about AMD.
3. Check memory with MemTest86
   • Yes, this take really long time, so do it overnight.
   • at least 8 passes
   • if you see a error, stop test, remove half of the RAMs and start over. If no error, do same with the rest to find out the faulty RAM
4. Check if memory sits tight in the sockets.
   • better to remove the RAM and exchange the sockets with other RAMs
5. Change power supply temporary

More tips to follow…

For me it was 2. which produced the random BSOD with memory issues.

Let me know what was for you the issue.

powercfg -requests

C:\WINDOWS\system32>powercfg /Requests
DISPLAY:
Keine.

SYSTEM:
[DRIVER] Realtek High Definition Audio (HDAUDIO\FUNC_01&VEN_10EC&DEV_0…01)
Ein Audiostream wird derzeit verwendet.

AWAYMODE:
Keine.

AUSFÜHRUNG:
Keine.

PERFBOOST:
Keine.

ACTIVELOCKSCREEN:
Keine.

will list the state of the exe’s.

So we can see DRIVER under SYSTEM there is Realtek High Definition Audio in use.

to override the request :

powercfg -REQUESTSOVERRIDE DRIVER “Realtek High Definition Audio” SYSTEM

now it should be discarded and you should be able to get your PC into sleep mode again.

Too sad that it does take research instead of an icon on the right bottom side which tells you: your PC wanted to sleep, but could not because of xyz. Do you want to disable xyz? do you want to disable this message? oh man… alles muss man selber machen :-)))

sfc /scannow will check filesystem for corrupt files when required.

cat /proc/device-tree/model 

output on rpi 1b:
Raspberry Pi Model B Rev 2

output on rpi 3b:
Raspberry Pi 3 Model B Rev 1.2

this simple approach might get complicated and have many ways to resolve, but here is my suggested solution:

counting down from 4 to 0,  use: =5-row(A1)

this might be useful if you want to transpose also the direction.

A                B
Head               formular

Index1                =index(a$2:a$4;5-row(A1))
Index2                =index(a$2:a$4;5-row(A2))
Index3                =index(a$2:a$4;5-row(A3))

counting down from 4 to 2 🙂

first check what's set: sudo locale 
second create the missing one with:  sudo locale-gen "en_US.UTF-8" 
third:  sudo dpkg-reconfigure locales

Also, if you have issues to use german Umlaute (äüöÄÜÖß) which is not show in the colsole, try to edit /etc/inputrc

# Turns off 8th bit stripping
set convert-meta Off

turn off reverse DNS lookups:
"UseDNS no" in /etc/ssh/sshd_config

1. Disable Windows Updates
2. install following KB updates,
KB3138612
KB3145739
KB3153199
KB3078601
KB3172605

3. Activate Windows Update again and try again.

bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd
diskpart
select disk [Nummer] (Windows Festplatte auswählen)
list partition
select partition (auf der windows installiert ist)
active
exit
dann neustarten und daumen drücken.

if you accidentally clicked SHIFT + LEFT ALT key, the keyboard switches the input language. you in German keyboard input you will receive an Z if you want to enter a Y. Just click on LEFT-SHIFT + LEFT-ALT key once and release, you should be back (or next language).

in order to disable the short cut, better go to control panel:
Language settings, advance, disable the keyboard short cuts (click on no action on the radio buttons)

what an annoying and useless feature for 95% of the users…

espeak mit mbrola kann plötzlich meinen namen nicht mehr aussprechen…
mbrola: Warning: t-EI unkown, replaced with _-_
oktay = okt ?

man kann die entsprechende phoneme datei ändern (suchen mit find /usr -name “mb-de*”)
vi /usr/lib/arm-linux-gnueabi/espeak-data/voices/mb/mb-de5
replace 0 EI aI
Oktay = Oktay 🙂

Folgendemaßen läßt sich die alternative Aussprache ermitteln:
espeak -v mb-de5 “Oktay” –pho
…
EI 77 0 153 80 144 100 144

espeak -v mb-de5 “Oktai” –pho (–pho gibt mbrola phoneme aus)
…
aI 77 0 153 80 144 100 144
