A bit stumped by these W7 BSOD's...

post #1 of 13
Thread Starter 
I bought a laptop off of Craigslist... all looked good, it's a Toshiba Satellite L505D-S5965.

Specs:
- Athlon X2 2.1ghz
- 3GB DDR2
- 250GB SATA HDD
- Windows 7 64-bit (shipped with Vista 32-bit)
- ATI Radeon 3100

Now he said that it was his girlfriend's computer, and she hardly used it because it crashed all the time under Vista. He had a friend put Windows 7 on it though, and said it was running great. Well, turns out, it's really not running that great.

It crashes and crashes and crashes, with no reasonable explanation as to why. I have reformatted the drive and reinstalled Windows 7, with the same result. I have swapped both sticks of ram with known-working ram out of my other laptop. I have run a dskchk from Windows, with it only finding a couple of files that were corrupted or mis-indexed, but it still crashed. I have prime95'd the processor up to 99c, and it still ran just fine, no crashing.

The crashes are almost always BSOD's, though I have had a couple of all-out hard freezes (mouse stops responding). They seem to happen if I start doing more intensive operations, such as opening more than 5-6 browser tabs, or updating windows while browsing the internet, etc. The codes seem to always differ, but a couple of the recent ones were bccode c5 and 19. They seem to always be hardware-related codes, but never indicate a specific piece of hardware.

The only thing I can think of is that it's either driver related (though I only installed drivers directly from Toshiba's website), or that there's really something wrong with the hardware, besides the ram, processor, and hard drive. Maybe the video card?

I'm out of ideas. What else should I try?

EDIT: Also, here's the full specs on the thing. http://cdgenp01.csd.toshiba.com/cont...505D-S5965.pdf

ndis.sys
ntoskrnl.exe
vwififlt.sys
Ntfs.sys

ntoskrnl is the only one that is in all bluescreens... I'm assuming that the problem lies there? I'll start researching on that - thanks for the excellent program!

EDIT: I may have found the problem. vwififlt.sys has to do with wifi, and I realized I never updated my wifi drivers after the Windows reinstall - I just let Windows use whatever default drivers it wanted to install for that. Updated the wifi driver with the one off of Toshiba's website, and it seems to be working much better now - I am multitasking like mad with no ill-result thus far...

Open a cmd window
-
Analyze the power comsumption of the computer, and lists devices with issues:

powercfg -energy

Diagnose why the computer is not able to enter sleep mode:

powercfg -requests


It may be useful to enter the commands as:

powercfg -energy >> C:\\pwr-energy.txt

powercfg -requests >> C:\\pwr-reqs.txt


these will create text files that contain the output upload them or copy and paste them here.

edit: didn't see your edit sorry but Its strange Toshiba gave problems with Realteks drivers as well. If you get any further problems do ^tests

Problem is fixed. Zero crashes since installing the Toshiba drivers instead of whatever default drivers W7 installed. Wooo, thanks for the help Spooony! Very glad it wasn't a serious hardware issue, which is what I feared..!

Lesson learned.

I was enjoying how I hardly had to do anything to get the computer up and running after a W7 install. Oh well.

Yes Windows 7 By default installs the incorrect Wifi driver. I had the same issue a few months ago.
