BSOD niemal codziennie - piotr1 - 27.01.2015 10:56

Witam,

Od jakiegos czasu niemal codziennie mam problemy ze swoim laptopem (HP Pavilion dv8). Wiesza sie kilka razy dziennie, czesto tez pojawia sie BSOD. Sprawdzilem pamiec i okazalo sie, ze jedna z kosci szwankuje wiec wczoraj ja wymienilem i obecnie mam wlozona tylko 1 nowa kosc 4GB - stare na razie nie sa zalozone. Memtest po 5 testach nie pokazal zadnych bledow, a mimo to od rana znowu problemy - 2 razy blue screen. Ponizej wklejam zawartosc ostatniego mini dump'a - mam nadzieje, ze ktos bedzie w stanie mi pomoc.

Pozdrawiam,

Piotr

RE: BSOD niemal codziennie - LadyInBlue - 27.01.2015 11:04

Po pierwsze wrzuć na jakiś hosting zawartość folderu Minidump.
Po drugie podaj specyfikację tegoż komputera.
Po trzecie: skąd masz pewność, że to kość szwankowała? Zmień gniazdo, możliwe, że to gdzie teraz masz RAM jest uszkodzone.


RE: BSOD niemal codziennie - piotr1 - 27.01.2015 11:15

Folder minidump: http://speedy.sh/q6WGJ/Minidump.zip
Specyfikacja:
OS Windows 7 Home Premium 6.1.7601 Service Pack 1 Build 7601
Procesor Intel® Core™ i7 CPU, Q 720 @ 1.60GHz, 1600 Mhz, 4 Core(s), 8 Logical Processor(s)
RAM 4,00 GB (wlozone wczoraj - wczesniej byly 2 kosci po 2GB)
Grafika NVIDIA GeForce GT 230M
HDD1 Hitachi HTS725050A9A364
HDD2 TOSHIBA MK5061GSYN

Z gory dzieki za pomoc!


RE: BSOD niemal codziennie - LadyInBlue - 27.01.2015 11:21

Zmień gniazdo, do którego wsadziłeś pamięć i zobacz czy wywala błędy Zadowolony


RE: BSOD niemal codziennie - piotr1 - 27.01.2015 11:22

Taki test troche potrwa - cos sugeruje, ze plyta jest uszkodzona?


RE: BSOD niemal codziennie - LadyInBlue - 27.01.2015 11:29

Zawsze może istnieć taka ewentualność. Zwłaszcza, że problem nie znikł po wsadzeniu nowej kości RAM.


RE: BSOD niemal codziennie - piotr1 - 27.01.2015 11:40

Ok, test leci na razie bez bledow. Wystarczy 1 petla?


RE: BSOD niemal codziennie - LadyInBlue - 27.01.2015 11:42

Jedna pętla to za mało, powinieneś testować z 5 godzin.


RE: BSOD niemal codziennie - piotr1 - 27.01.2015 12:14

W takim razie niestety bede to musial zostawic na noc. Na razie zrobilem 1 test i nie pokazal zadnych bledow. Jakies inne sugestie?

Dopóki nie przejrzę dokładnie bsodów nie jestem stanie nic innego wymyślić, dojść do wniosków, znaleźć wspólny mianownik (bsody mają różne kody i na pierwszy rzut oka różne przyczyny).
Jaki to jest dokładnie model tego Pawełka bo tyle co napisałeś to ja już wiem z pierwszego bsoda jaki poddałem wstępnej obróbce ?


RE: BSOD niemal codziennie - piotr1 - 28.01.2015 11:00

OK, memtest po testowaniu 2 slota pokazuje zero bledow - 6 godzin pracy, 7 iteracji. Zapuscilem go jeszcze raz, ale tym razem ze stara koscia 2GB na 1 slocie i po 8 godzinach pracy zero bledow.

Model to HP Pavilion dv8 1110sw.


RE: BSOD niemal codziennie - piotr1 - 29.01.2015 11:27

Od czasu jak napisalem pierwszy post byl spokoj, az do dzisiaj - od rana 2 razy BSOD i 2 zwisy. Ponizej zamieszczam zawartosc obydwu dump'ow. Zaraz po 2 blue screenie zapuscilem memtest i niestety tym razem nie obylo sie bez bledow - screen tutaj
