BSOD when restarting windows after exteneded user session.

well, for instance, recently my IP address was the victim of a coordinated DDOS attack recently, and it was killing my speed. So my ISP wanted meto hook up my laptop directly into the modem temporarily so they could take some kind of speed measurements or something. I normally have my laptop connected to Wi-Fi, so when they asked me to go to the ISP's speedtest site and test it with the way I normally connect

and then test it when it was directly hooked up to the modem. even with my laptop's HDD protection features, I know that moving any thing with a spinning hardrive is a big NO-NO. I also know that moving a laptop when it is in sleep mode is also a big NO-NO. Hiberate saves the windows session to the hard drive and turns off the computer, which mean the hard drive's internals can withstand external movement without incurring possible damage or data loss. since resuming from hibernation is quicker than booting from shutdown, and I did not want to have to bring all the windows (browser pages, etc.) again, hibernating the laptop was ideal.

since I have 8gb's of RAM, I have it set to system managed. My system uses traditional mechanical HDD's rather than not Solid State HDD's.

I believe I did answer the whether I used Disk Cleanup

"   I use Disk Cleanup, but I click the "cleanup system files" option before I start selecting any cleanup options. I run it Bi-monthly unless I feel there is a need to do it sooner.

I also run my malwarebytes (free version) scan weekly and a Spybot Search and Destroy scan one a month. I run a full antivirus scan using Microsoft Security Essentials at least twice a month. the quick scan is setup to run every Sunday. for all three of these programs, if I suspect there might be a problem, or if I am trying out a new utility or program, I run them immediately after said utility or program install. this routine has kept me virus, malware, and spyware free for many years.   "

My computer performs quite well, it is just on the occasions when I have had a windows session running for more than a week and I then try to shutdown or restart windows that I start seeing problems. If I do what might be considered a normal length windows session, (less than 1 day) then I see no problems. what so ever.  "

and I don't want to lose my windows session

Why? What do you gain?

My judgement on defragmenters is based on personal observation and from using the products. I am very wary and reluctant to accept spin generated by software providers. Automatic Defragmentation comes at a price. You can reduce fragmentation by having a fixed size pagefile. Are you using a system managed page file or a fixed size pagefile?. Of course you should not defragment a solid state disk so that goes towards rendering a disk defragmenter redundant.

You did not answer this question. Are you using Disk CleanUp or cCleaner? How often do you run whichever utility you use?

How are getting on with the real issue which is getting your computer to perform free of error and to a level that satisfies your needs?

Since Diskeeper might be involved you need to check with its support and forums for

any known issues. Please uninstall at least as a test and run without if for at least the

period of time it takes to ensure it is not involved.

Very often these sporadic BSOD issues are caused by the interaction of more than one

driver and/or program. So they can be extremely difficult to resolve. Though games which

stress the system and drivers are the most frequent culprits any program can be involved

(or even more than one startup or running program).

And there is always the added issue of heat (which does not always mean there is excessive

heat as a single component could be too sensitive to even the normal levels of heat).

I use hibernate usually when I am about to move my laptop to a new location and I don't want to lose my windows session. although I do perform regular battery "exercise" (unplugging the laptop until windows says it has reached reserve power levels), I normally keep it plugged in to the power supply as I infrequently move the laptop. My internet router is in inconvenient location for me to use it's Ethernet port, but that is okay. My internet connection is only 6Mbps down and 1Mpbs up, and I have full signal strength through out the house and get 72Mbps through my wireless connection to the router. this is much faster than the internet connection speed. when I perform a speed test, I can get the full 6mpbs down speed through the wireless connection (as long as no one else in the house is online too). I feel that having the full 100mbps of the Ethernet connection would result in a lot of wasted bandwidth since the connection to the internet is only 6mpbs. I am able to use RD (remote desktop) and RA (remote assistance) through both the local network and over the internet with all features enabled, so I am happy just using Wi-Fi.

many third party defraggers still use the api calls of windows defragmenter. I am not familiar with defraggler, so I won't make any statements on how it is (better or) worse than windows defragmenter or Diskeeper. Diskeeper 12 Professional, when all features are enabled has actually improved my access times on my laptop. the autodefragment feature defragments the system in the background. Since I use ReBit for my system backups which uses VSS, I have diskeepers VSS settings turned on, which the system is not constantly creating new shadow copies every time a file is moved during a defrag. I have it set to the extensive autodefragment setting, which allows for free space and directory consolidation, the intelliwrite feature keeps files from becoming fragmented as they are created. and I use diskeepers I-FAAST feature which move frequently accessed critical windows system files to the beginning of the drive. Diskeeper performance history is actually showing a 41% read and write access time improvement over the last 12 months.

these features are the reason why I chose Diskeeper above other available products

IntelliWrite®

IntelliWrite® fragmentation prevention is a ground breaking technology that prevents the majority of fragmentation from ever occurring, dramatically improving Windows system performance. A small percentage of fragmentation is not preventable and will be eliminated by Automatic Defragmentation. The combination of IntelliWrite and Automatic Defragmentation will keep your system running at optimum performance in the most effective and efficient way possible. Prevention of fragmentation with IntelliWrite has been found to be more efficient than other defragmentation methods. IntelliWrite reduces the need for disk head movement and results in a reduction of system resource usage and power consumption.

I-FAAST

A Diskeeper exclusive, I-FAAST® Intelligent File Access Acceleration Sequencing Technology improves file access and creation on NTFS volumes by up to 80% (average 10%-20%) above and beyond the improvement provided by defragmentation alone. This is the first industry implementation of "Disk Performance Calibration", the modern evolution of the outdated and inconclusive disk optimization strategies of the past.

InvisiTasking

InvisiTasking® technology is a proprietary technology developed by Condusiv Technologies that carefully monitors resource consumption on a Windows computer system and injects Diskeeper processing into the unused portions—and only into the unused portions. InvisiTasking is so good that it is all but impossible to even detect whether Diskeeper is running.

I/O Smart

The Diskeeper I/O Smart® feature intelligently monitors drive access during defragmentation to ensure top system speed. Diskeeper will temporarily suspend defragmentation whenever other disk activity needs to occur, automatically (I/O throttling). This proprietary technology detects whether or not the disk is busy with other I/O requests and pauses defragmentation to eliminate any potential interference with user or system needs at the "disk" level.

Instant Defrag This enhancement to Automatic Defragmentation immediately eliminates any fragmentation that is not proactively prevented with IntelliWrite. Rather than waiting for potentially extended periods of time for fragmentation to build up, this feature provides uninterrupted peak system performance. Progressively more beneficial the larger the volume, Instant Defrag also saves system resources by minimizing the need for volume-wide analysis and defragmentation tasks.

directory consolidation

A Diskeeper feature that gathers (almost) all directory entries on a disk volume into a single area on the disk, instead of scattered in many places. Directory consolidation makes defragmentation more effective than it would otherwise be. Directory consolidation requires sufficient contiguous free space into which the directories can be moved.

HyperBoot™

HyperBoot technology optimizes system boot processes to allow for faster system boot times. As applications are added or profiles expand, boot-up times become longer and longer. HyperBoot accelerates full computer start up and boots a PC directly into Windows.

I use Disk Cleanup, but I click the "cleanup system file" option before I start selecting any cleanup options. I run it Bi-monthly unless I feel there is a need to do it sooner.

I also run my malwarebytes (free version) scan weekly and a Spybot Search and Destroy scan one a month. I run a full antivirus scan using Microsoft Security Essentials at least twice a month. the quick scan is setup to run every Sunday. for all three of these programs, if I suspect there might be a problem, or if I am trying out a new utility or program, I run them immediately after said utility or program install. this routine has kept me virus, malware, and spyware free for many years.

I  used this routine on my old XP desktop as well, and it served me quite well then too.

Back when I first got my laptop, and on the occasional factory reset, I use Pc DeCrapifier ( http://pcdecrapifier.com/ ) to get rid of some of the preloaded junk that Toshiba tries to push onto me.

Restarting the computer assists maintenance by refreshing the system. It is also one of the first things you should try when you encounter a system error. System performance on a desktop computer is better if hibernation is not used. You do not have this option on a laptop because the computer relies on a battery for it's power supply. If you turn off hibernation you can easily flatten the battery if it is not connected to a mains supply beyond a limited period of time.

With a computer it is better to use an ethernet rather than a wireless internet connection when carrying out large downloads. Downloads are quicker and less problematic. Many users do not appreciate this point and it is one explanation why so many problems are encountered using Windows Update. A laptop should be connected to a mains power supply when carrying out a large download.

You have pointed out that the Defragmenter provided by Microsoft is a lite version of Diskeeper. I prefer to use Defraggler because you cannot manage fragmentation of large files with the built in Defragmenter. It ignores files over a certain size and misreports the percentage fragmentation. This leads to fragmented free space. When free space is fragmented any new files over minimal size tend to be fragmented immediately they are written to disk. I do not know, but it is quite possible that Diskeeper has the same defect. Using Defraggler the user has greater control over the process and can see more easily what is going on.
