I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

My BSODs continue. Starting to wonder if it could be a motherboard issue. Have been running many memory tests and none reports issues with the memory.

All components are less than 5 months old. I have re-installed Windows from scratch several times and I dont have a antivirus software installed. I have replaced the OS disk with a completely new one, since I thought at some point it was related to the hard drive.

Please, any help would be really appreciated!

I bought a pc two weeks ago and I had random BSODs without dump files so I reinstalled the operation system (win7 professional sp1 64bit).
I used it for a week or so and BSODs appeared again, but now at least I have dump files (I attached them). I would appreciate any help or suggestion and sorry for my bad English.
Thank you!

A:Random BSODs win7 64bit

I will leave the BSOD help for the experts in BSODs. But do you know that your graphics card requires 450w to run and then you have everything else to power and you only have a 450w psu? This means your system will be struggling and will be contributing to your crashes if not the full cause of them.

Just today, the 28th i started getting bombarded by BSODs, like 8 of them on diffrent games such as:

Arsenal of Democracy

I added all the minidump files. Unfortunately i cannot diagnose those as my debugger is giving symbols errors even though i installed it and reinstalled it...

I used the one with Windows SDK...

My video card 5750 Radeon ATI Mobile
help analyzing those would be great help.
My CPU i7 720 Q 1.6 GHz

My memory 8 GB PC 8500.

Small update:

It doesn't just happen on games. When i surf or just use partition software...

I downloaded latest adapter for my Intel WiFi. I had this laptop for two months, it hasnt been crashing like this before...

My system is about two years old, and over the past few months I've been getting various BSODs. It seems to me that it is related to a memory issue (or HDD?), but I have not been able to narrow it down at all.

I have tested each stick stick individually for hours with Memtest86+ but I have gotten zero errors. I also have another computer with the same specs running fine, so I do not believe it is due to incompatibility between the mobo & RAM.

I've attached the requested files and really appreciate any insight into my problem.

Hey guys. Background on my system: It's a Dell Latitude E6520, purchased July 2011, Win7 Pro 64-bit. Has been very stable for me until recently.

In the past few months I've managed to catch some malware, and a couple times successfully fixed the issue (or so I thought?) with Malwarebytes and other methods as needed. Lately, past few days, I"m not sure why, but the system has been unstable. I was getting multiple BSODs and thought I fixed the issue. If the computer goes on idle though, it can't be woken up and if I press the power button it'll shut right down (usually, if I was going to hard boot like this I'd need to hold it down a good few seconds). Powering back on brings me to the startup repair options. Only a couple times have I been able to get to the actual startup repair menu where I could run all the different options, such as fixboot, etc., and I have done that. Most of the time the system begins checking for startup issues and never gets past that point before I have to hard boot again. then I just select "start windows normally". I do have a startup repair disc I created, but I've already tried the options and it's not solving my issue.

Just now I searched for issues related to certain .dll files showing an error in the Event Viewer; sysmain.dll and wcp.dll are the ones I see under error code 1005 for two days ago and yesterday. Not sure what to do about this - unfortunately I cannot find my windows 7 disc (not even sure if my system sh... Read more

So I built my third PC in May of this year and have been increasingly experiencing problems. These problems include inability to install SP1, IE crashing, Firefox crashing, and even more frustrating, BSODs.

The errors I received when trying to install SP1 were 0x80070570 and 0x80070490. I looked them up and tried all the suggestions that I was allowed to do. For example, I was not able to complete a disk check before startup because of some error.

This led me to finally do a repair upgrade which was suggested in some forums. I followed a PCWorld article and did what they told me until during the upgrade repair, I received error 0x80070241. It says some of the install files were corrupt or something along those lines.

I am not very computer savvy, so if you can please provide a link for help that requires me to do something above a normal computer user's capabilities would be appreciated. I've started graduate school and I really need my computer to not crash and BSOD. Please help and you'll have my undying gratitude forever! Thanks!

Hello, new to the forum. I'm usually good at googling and finding answers to help myself. But this time, I need someone more knowledgable. I am including a Speccy Snapshot link. Well today I was playing The Vanishing of Ethan Carter on max settings. I also had a Firefox tab open and was uploading a video to Facebook. And, I also had Nvidia ShadowPlay on and was recording my gaming session. All of a sudden I got the Clock_WatchDog_Timeout BSOD. Then it stopped dumping at 45% I left the computer for awhile, came back, and was still stuck on 45% Probably a bad idea, but I then restarted my PC. I'm not too comfortable with trying to reproduce the same BSOD, did some googling, and decided to see if someone can help me pinpoint the issue. Is my CPU bad? I will admit I do have my CPU overclocked to 4.6ghz, but honestly don't even know if I did anything right. I'm not exactly a pro at overclocking. I don't have anything in the Minidump folder. How can I go about making Win 8.1 save dump files? Whatever info you need from me let me know. Thank you for your time!

A:Clock_Watchdog_timeout win8.1 64bit

You need to stop overclocking and see if the problem persists.
I can't do much witout a dump file unfortunately.

I've been having constant blue screens for a long time.

It used to be on Windows 7, but I made a post and there were no replies so I tried to upgrade to 8.1 (already had a disc) hoping to have that solve some problems.

They are less often now but I've still had 3 today.

Any help would be greatly appreciated, this is a very frustrating problem for me.

Note for attachments: The one labeled 'TEST' is from this install of Windows 8.1, the one labeled 'Cory' is from the Windows 7 install, I included it because there are dozens of dump files in there that might also be useful.

Hibernation issues usually involve video, storage, and chipset drivers - please update them all. If you already have the most recent versions, please uninstall them and then install a fresh copy.

Running the May and June memory dumps (11 of them).......
And nearly all of them blame HssDrv.sys - a driver component of HotSpotShield.
Please uninstall the program to see if it fixes the problems.

You have a 341 mHz overclock - I'd suggest removing that until the system is stable again.

Please check the links below for drivers dated 2009/10 and earlier.
Then use the links below that to find and update these older drivers.
In particular, your chipset drivers are very old and should be updated.

A few times lately I've gotten random BSODs with the message 0x000000c2 BAD_POOL_CALLER and also I got one the other day that had 0x1000008e KERNEL_MODE_EXCEPTION_NOT_HANDLED. Both were always caused by the files ntkrnlpa.exe and win32k.sys. I haven't updated any drivers lately but they're up to date, windows updates are done as they come out, and I haven't installed anything new hardware or software wise for about a month (these crashes started just last week). I have also scanned thoroughly with various utilities for viruses and malware and there were no results. I have run memtest for 20 hours and verified that there was nothing wrong with my RAM, and I have run various hard drive error checking utilities and my hard drives are perfectly fine every time. The BSODs don't seem to be related to any specific action I do... I have gotten them in the middle of browsing the internet, while moving and renaming files, and even once just not even touching anything at all as I was out of the room and came back and it was on the screen. Also lately I have had an unusual amount of random freezing and sometimes even crashing lately with every program I use regularly so I think that could be related. Could someone tell me please what's most likely causing these, if it means something potentially fatal to my hardware or data, and how to fix it?

Hello everyone,

I bought this laptop september 2013 (FYI Windows 8 recently came out at the time) for school. I started having a BSOD (Bad pool caller) when I tried torrenting at the time but only when I had utorrent running. So, I decided to stop torrenting at school and use it strictly for class (Chrome and Microsoft suite). Fast forward to two weeks ago and after having updated a few things, I thought I'd try torrenting again.

I'm still getting BSODs while torrenting which sucks but now I get them without utorrent running. I'm either taking notes on Word, browsing, listening to music or all 3 when it happens. I've got BAD_POOL_CALLER, K_MODE_EXCEPTION_NOT_HANDLED and IRQL_NOT_LESS_OR_EQUAL so far. I had more dump files but I think the older ones disappeared when I installed a program to read the dump files (BlueScreenViewer).

Things I've tried :
-Update to latest stable version of utorrent
-Install latest drivers for GPU/CPU/Windows 8.1 (it said wifi adapter is up to date)
-Run C Cleaner for registry stuff and everything else
-Installed MalwareBytes Anti-Malware (found nothing as expected)

TL;DR BSODs while torrenting and now without torrenting

Thanks for your time!

I've never, EVER, in my whole life experienced any kind of BSOD in XP(sounds crazy I know), but lately I've got 4 of them in the last 2 weeks. So naturaly, I'm really iritated right about now.

The first one was caused by tdi.sys and after lots of googling, I downloaded the debugging tool and opened my first ever minidump. Again after a lot of googling, on one forum it was advised that I change the tdi.sys located in:


with the one from:


I did and that BSOD didn't happen again. I was soooo happy.
Few hours later I was greeted by another BSOD and after opening the minidump it said it was caused by afd.sys. That file caused my latest 3 BSODs. What does it do and can I update it somehow?

Before my latest BSOD I disabled the automatic restart so I can see if the BSOD itself gives any more information. Here's what it said:

BAD_POOL_CALLER and below 0x000000C2 (0x00000007, 0x00000CD4, 0x000001AE, 0x89472EEC)
After some more googling I found out that 0x000000C2 is cause mainly by corrupted drivers or something.

After each BSOD, after rebooting, XP starts and works normally. SP3 is running(installed months ago after a fresh windows install).

Please see minidumps attached.

I've been having BSODs about every other day for a couple of weeks. Bluescreen View usually cites ntoskrnl.exe as the driver cause. This most recent BSOD has Bluescreen View citing afd.sys as the driver cause with ntoskrnl.exe+7cc40 as the driver address. This is the same address mentioned in the previous BSODs.

Attached is the requested zipped Windows_NT6_BSOD_jcgriff2 folder and perfmon.html

Also attached are 2 pics of the info screen from bluescreen view for multiple dump files, giving an overview of each (only the latest dump is represented in the Windows_NT6_BSOD_jcgriff2 folder.

System specs:
-Win7 pro x64
-OS is original installation
-full retail
-system is ~3 years old
-OS installation age ~3 years (no re-installation/etc. since I built the system, OS was installed clean to new HD, no upgrade from previous OS)

Computer boots up fine, runs for hours just fine. There is no common activity at the time of crash (sometimes in World of Tanks, sometimes just using firefox to browse, sometimes when unattended and no program running other than the background programs). I do hear a buzzing sound as the crash occurs but unsure if that's a cause or effect.

What I've tried:
-swapped out keyboard
-drivermax says all drivers are up-to-date except nvidia display (didn't install the 3D drivers) and they're 296.10 -- pretty recent -- and were a clean install (uninstalled the old ones, safemode reboot and deleted all traces then used driver sweeper, etc.). Sound card drivers... Read more


I am a big fan of Nir Sofer's work, BUT blueScreenView more often than not, doesn't point out the correct causes. Similarly Who crashed is even worse.

We prefer to use WinDbg (the Windows Debugging Tools) to read the memory dumps. It is the Gold standard for those of us that do this and often will give us the answer by itself. (we don't need the full jcgriff2 report each time).

If you look at parameter 1 in all the BSV crashes it is a C00000005 (which is a memory exception).

Before we begin to investigate that there is one thing you need to do which may solve the problem in itself.

Asacpi.sys. Yours is from 2005

The pre 2009 version of this driver is a known BSOD cause.

Please visit this link: Asus tek computer inc. -support- drivers and download p7p55d le

ASUSTeK Computer Inc. -Support- Drivers and Download P7P55D LE
ASUSTeK Computer Inc. - Motherboards- ASUS P5K-VM

Scroll down to the utilities category, then scroll down to the "atk0110 driver for windowsxp/vista/windows 7 32&64-bit" (it's about the 12th item down).

Download and install it.

Go to c:\windows\system32\drivers to check and make sure that the asacpi.sys file is date stamped from 2009 or 2010 (not before).

If after updating the asacpi.sys you are still crashing with the same parameter please run the following tests

These crashes were caused by memory corruption/exception (Cx05) probably a driver.

Hi every one,

i have this machine which is causing too much headache for me,

this machine was having Windows XP 64 Bit,
and it had a lot of BSOD crashes, then i just decided that it's the time to make the move to Windows 7 for this high performance machine, since i was not able to upgrade to Windows 7 because of some applications just working on Windows XP 64 Bit, but now there is a copy of it,

Any way i'm still having those BSOD crashes,
I have replaced the SSD 500GB hard drive with another regular hard drive with no results,
tried to remove and install nVidia Driver,
tried to install a different version of that driver with no results,
tried to remove McAfee AV and installed Kaspersky Internet security 2013 also no result,

now i have grabbed all the data using SF Tool, and i really hope that u can help me with that issue.

thank you

Initially I thought that the trouble was caused by the Avast Virus Scanner " Auto Sandbox" I disabled it but the BSOD'S continue.

There is no sense adding more software to this system until the problem is sorted out. I have a dual boot system with XP Pro as the other OS. I can easily blow out the partition for 7 and start over. But all I would be doing is repeating the same errors as before.

Very discouraging for a new install but I can do it again if that's what it takes to cure the problem.

Thank you in advance!

I purchased the Win 7 Pro Upgrade 32bit via digitalriver, but I've been doing some reseach and probably should have selected the 64bit version.

- Any ideas how I can get the 64bit version?

- For those who ordered the 32bit back-up disc kit for the extra $15 and have received it, does it come with both 32bit & 64bit?

- I've already installed and activated the 32bit version, but when I go to install the 64bit version, will I need to / is there a way to deactivate my initial 32bit install or will this not matter?

Thanks for your advice.

I have a new Toshiba Laptop (Win7 64bit CORE i3). I would like to run (via usb) and old hdd from my desktop which was 32bit Win7.
I have the old hard drive in a SATA enclosure and running it via USB to my laptop. When I attempt to either copy or read the old hard drive I get a write protect error. I have tried
the MS registry changes to remove "write protection" but the registry entry they call for is non existent in my laptop registry.
My last post on this was annotated as solved...but my explanation was weak. I do not want to run this drive as a permanent addition to my system, I just need to copy some files from the old drive to the new one.
If I attempt to use Control Panel/Disk Management it tells me the old drive is not "initialized". Both options to initialize don't work. Please help I have some very important medical records that must be copied from old hdd to new.

Hi folks.

I have searched through the various threads that deal with this topic but have not seen anything that deals with this specifically.

I have a custom built computer I put together last year. I installed Win7 32bit at the time because I didn't want to bite the bullet and reinstall everything. That time has now arrived.

My computer has:

i7 Core 960 2.67GHz
8GB Ram
1TB HDD (Win7 32bit installed)

I purchased an OEM DVD of Windows 7 Home Premium 64bit and an Intel 180GB SSD drive.

I want to install the SSD drive on the computer and install Win7 64bit OS as a DUAL BOOT. This way I will be able to choose to migrate my applications at my own pace. As I install a 64bit version of my Photoshop CS6 for example, I will delete it in the 32bit OS once I have all my settings, brushes etc. moved over.

Should I ?

1. Install the SSD and get it recognized by the BIOS and the 32bit OS.
2. Boot from the DVD of the 64bit OS and choose the SSD as the location of the installation.
3. Reboot the computer after installation complete

and at that point I should get the dual boot screen?

The above is how I understand the process based on some tutorials I've seen for dual booting XP and Vista. Does this work for Win7 32 and Win7 64?

A:Dual Boot Win7 32bit and Win7 64bit on a second SSD drive

Easy - install the SSD and disconnect all the HDDs. Then install Win7 on the SSD and make the SSD second in the boot sequence (first should be the CD/DVD reader). Then reconnect the HDDs.

When you want to boot from your 32bit system, temporarily change the boot sequence (usually via F12 at power-on).

Hi all,

Hope all is well. I just purchased a Toshiba Satellite P855-S520 laptop with Windows 7 Home Premium (64-bit), SP1 already installed and would like to upgrade it Windows 7 Ultimate.

I had already purchased a retail version for Win7 Ultimate before (the full version not the upgrade) and would like to use this for the upgrade.

I looked around the forums for some advice and found some very useful stuff but I would appreciate if someone could help with the following. My apologies if the answers were posted already. Must have missed them.

1. I read about the Windows Anytime Upgrade feature. Will AU work with the full Win7 Ultimate retail key or does it specifically work with an upgrade key?

2. If I use the AU and it is successful, will the new Win7 Ultimate key be converted to an OEM version as well? The full-version retail key I have gives me the right to install this to 3 computers. I do not want to lose this right since I may use it for different computers in the future.

3. Is it better to go for AU or a clean install of Win7?

Since I just purchased the laptop, I have no personal data or programs installed so I do not have to worry about losing data. However Toshiba has certain software installed with the laptop. My understanding of a clean install is that everything will be wiped clean and then necessary software e.g. drivers, etc... need to be installed again. On the other hand, once I upgrade to Ultimate perhaps some of this software will becom... Read more

A:Macrium Reflect: Restore Win7 32bit to Win7 64bit?

NO -- a clean install is required to move from one to the other. IF you restore an MR backup over an install, it replaces the entire contents of the partition. So basically, you would be going back to the version that you saved to backup.

I have purchased and downloaded both 32 bit and 64 bit Windows7 Professional (no CDs or media here only download version)

I sucessfully upgraded from Vista 32 to Win7 32

Then I upgraded my hard disk (140Gb 500GB) and RAM (3GB to to 4GB)

Now I would like to go from Win7 32bit to 64bit

When I try and run the Win7-P-retail-en-us.x64.exe file it upacks the box then stops with this error:"We are unable to create or save files in the folder in which this application was downloaded. Please check the folder properties to make sure that you have security permission on the folder to write flies and that that folder is not read only"
I am the System Admin and I have full rights, and have moved the exe and the setup box files to My Documentsand I have modified the directory properties/attributes but I still get the same error over and over.

I searched the posts and some people stated one needs a clean install others say you can upgrade from any version so I am trying the upgrade here especially since the upgrade from Vista 32 to Win7 32 was smooth and did require all the extra work of a reinstall.

Can someone help me here?


A:Win7 (32bit) to Win7 (64bit) upgrade install error

I believe to go from 32-bit to 64-bit, you will have to boot off the DVD. The installer is a 64 bit application that won't run under 32-bit. Find instructions to create a DVD if you don't already have it.

Good luck!

I have a legally purchased win7 Premium (32bit) CD. I purchased a new desktop that is pre-loaded with win 10 (64bit). I prefer to stay with win7.
Question 1: If I do a clean install of my win 7, will it work properly? At least until win7 support shuts down in 2020.
Question 2: Since the new computer has 64 bit architecture, is it possible to upgrade my win7 (32bit) to (64bit) using anytime upgrade?
A little info: I understand there may be a little loss in performance, but, for my purposes, that would be irrelevant. I just don't like win10.
I'm a senior on fixed income. Had to save for a full year to buy the new desktop and simply cannot afford to purchase a 64bit win7 (if it is even still available)! ...and Don't really want to go the 'pirate' route.
Any simple (layman) advice would be gratefully appreciated.
Oh, one more thing. I have made a backup of the win10...in case I have to go back to it in the future.

I have read many of the similar posts...but they were either confusing or not quite answering my specifics.

I am working on a Dell Studio 1745 running Win7 64 Home Premium. I need to run a piece of hardware (Tascam US122) that is incompatiable with the 64bit OS. My plan is to partition the drive and install Win 7 32bit on the new partition so I can run the mentioned hardware. I've done this on another machine (Dual Boot XP and Win 7) and ran into a problems with the bootloader. I learned to install older OS FIRST because of that. I'm wondering if installing Win7 32bit on a current Win7 64bit machine will cause a similar problem with bootloaders? I'd rather not have to mess with the bootloaders, but I really need to run this hardware. And, since this is a Dell, with touchscreen, and most IMPORTANTLY, a friend's computer I want to be 100% sure I'm not going to cause issues I can't fix.

So, again, will installing Win7 32bit on a new partition of a Win7 64bit machine cause problems with the bootloader, or any other foreseeable problems?

Thanks a bunch!

I have read the directions on how to do a clean install but have no way to know if this would be classed as a clean install. I may not be the brightest bulb on the tree but I am very careful. It's been a few years since I've had the hood up on a computer but I do know my way around inside, even know what some of those things are in there.

If it's going to be installed on a separate computer and you have a second key to activate with, then yeah you could do a clean install with it like in the tutorial below.

I am currently using Windows 7 Home Basic 32bit. I acquired Windows 7 Professional 64bit through MSDNAA and was wondering about how the OS change will go.

What I'm worried about are my files. I currently have about 200gb worth of data on my drive and I have no extra harddrives to make backups.

Because I'm going from 32bit to 64bit, I read that a clean install is required for this type of change. My question is, will my files be placed in a "windows.old" folder? Or will I be required to buy an external drive and transfer them all in order to keep them?

Are there any other things that I must keep in mind?

Hello all,

I upgraded my system to Windows 7 32bit (from Vista) back when there was the student discount. And am regretting it now since i work in Photoshop all the time and need more RAM to suppose the work i do. So i'm looking to upgrade my system to the 64bit equivalent of what i already have (Home Premium).
I understand you can't use the Windows Anytime Upgrade for a 32bit to 64 bit upgrade. I also understand you need to do a clean install, which is no problem.

So what my question is, is what product should i buy exactly? Can i get away with an upgrade only? Or do i have to buy the full product?
I still have my Vista CD, so i could re-install the 64bit version of that, then buy the Windows 7 Home Premium 64bit upgrade?
Or is there a simpler way?

You can buy the Upgrade key because you have a previous OS already (Windows 7 32-bit).
