Random Windows 7 Ultimate Overnight Crashes - Minidump Implicates Iastor.sys
Feb 22, 2013
I'm experiencing random overnight crashes, always similar to below minidump (below) results (iastor.sys is implicated) but cant figure out what brought it to this point. System is up to date, iastor.sys hasn't changed since 2/1/2012. Ran Malwarebytes and Norton360 scan. System is clean otherwise.

I've spend the last week scouring Windows 7 Forums finding dozens of people with this issue. At random times, during use or idle, the computer goes blank and reboots.Starting from a clean install of an OEM copy of Windows 7 Home Premium 64-bit on a formatted HDD
1. Updated all drivers for my devices for Windows 7
2. Loaded and installed all current Windows Updates
3. Flashed and updated the BIOS
4. Ran the driver Verifier, did not see any errors reported
5. Tried to run sfc /scannow, system reboots when the scan gets to about 60% (tried twice)
6. All non-necessary devices (printer, external HDD, etc.) are disconnected.
I would attach a minidump file but there isn't one. I've got the system set to record one but it's not there. I have the view set to display all hidden files/folders. I've done searches for *.dmp files and typed in the address I've got set in the options ... no dice.I never get the BSOD, I have it set to not automatically reboot. It still goes blip and restarts anyway. There's no real pattern to the restarts but it loves to do it in the midst of installations.I've held off running a memory test simply because all my fellow sufferers keep reporting no errors in the memory and any time I do anything time consuming it fails when the system goes blip again. System Info via Advisor attached.

Been having some crashes.At first they occurred on start up. Claiming the computer wasn't properly shut down. Now today, the other crashes started, with the first happening out of nowhere, the second happening upon starting a video game. I've been without crashes for a while now, only having used my browser(Opera) and copying some files to an external hard drive. As well as the SF tool.I only have 2 dump files available. SF tool file should be in attachments, unless I made a mistake somewhere

I'm having a problem with a new computer I bought with Windows 7 (64bit) installed. At seemingly random points in time it will crash on me completely. I've managed to find out from a dumpfile that the likely cause of this problem is something called Rdyboost.sys I've managed to find it listed as a driver in windows/System32. Apart from that though I'm not sure how to find it, and was wondering.

I have an ACER ASPIRE 5739G running Windows 7 64-bit.No changes were made on the laptop over the past 2 months, suddenly I started to encounter the "blue screen of death" once every few days, randomly when browsing the internet (no other software was running). It started to do this more frequently, within 1 hour of EVERY startup, I then performed a system restore and now the blue screen appears within 30 seconds of every startup, as well as Safe Mode.The blue screen appears for 15 seconds, the laptop then restarts.I have attached an image of the blue screen below:I know the most obvious solution will be to re-format the hard drive, as the computer is rebooting within 30 seconds of each start up as well as safe mode.Is there any way for me to browse the hard drive on the laptop without loading up the OS, to transfer to another laptop/external HD?I have a couple of really vital documents (only 10mb worth), although the laptop reboots before I have the chance to transfer them to a USB stick.If there was a way to transfer these files, I would be more than happy to re-format the laptop.

I reinstalled Windows 7 64-bit on my computer (HP p6510f) about a month ago. All went well for about a month. But now I get these random crashes. There doesn't seem to be any rhyme or reason to them. Happens when I surf the net, listen to music or play a game. The computer usual runs well for several hours to a day, then WHAM-O! The computer freezes up and I have to re-boot.
I don't get the BSOD and I'm always able to re-boot quickly. What troubleshooting steps should I take? I hope there is a fix to this because I'm getting pretty frustrated over this computer I've only had for a couple of years.

I had a PC with a Windows 7 install for the last two years that had a motherboard go bad. I ended up buying a Tigerdirect combo (hardware specifics below) and just decided to reuse the case with my original install drive. After taking some time to retune itself to new drivers, the computer kept freezing at random times. In some other forums on this site, I thought it driver related (even though I had updated everything including new MB bios). To make things easier, I installed a new 80GB SSD drive and put in a fresh install of Windows 7. Have updated everything to the nines and avoided adding any additional software until I had data and stuff organized from my previous install. However, the randome gremlin seems to have come back at random times.
I've tried setting memory frequency from auto to the speed in the BIOS, but found this thread and have attached the BSOD zip file for some help. Any thoughts on what is the issue? It may be a hardware problem, but I have run memtest on the memory and just can't seem to find the culprit.
Specs:
MB = MSI H61M-P23
Processor = Intel Core i3-2100
Memory = Patriot 4GB DDR3
Windows 7 Professional 64bit

I recently had a virus on my computer and did a clean install of Windows 7 Ultimate. Now it seems that randomly my processes will stop responding, usually if I have a couple things running at once. I cant seem to burn a DVD because every time it will crash during it. Usually when it happens all the processes wont respong, task manager wont come up and a couple minutes later my system restarts. I have run a memtest and it turned up with no errors.

I've been having increasing problems with my Asus g73jh. Love the performance, but been having random crashes concerning video i assumed. Updated the graphics drivers as well as ran a bios flash on the laptop. The unit always has a problem with being moved and I just moved it for the first time in around 6 months (been using it connected to my screen in living room) to bring to class and it crashed with a page fault error when I arrived at class, then again with another bsod when I got home and unpacked it.

After going from the E5200 Dual Core to the Q9550 Quad Core windows freezes on startup. If I try to do startup repair it crashes there too. I get the black screen of death, no error message or anything. If I re-install the E5200 it works fine. I would like the get the Quad core working. It's already been replaced once. I'd rather not have a $200 paperweight.

I've recently received a laptop which has Windows 7 preloaded. About a week after starting to use it, I started experiencing random crashes while CPU intensive operations are occurring. I don't even get a BSOD, the screen just goes black for about .5 of a second and then the entire computer just shuts off. Furthermore, I've scanned for any malicious software, bad packets, etc etc. and those scans returned nothing.

Recently, my computer has started freezing while I'm browsing the web. No BSOD or resetting, it just freezes and I have to hold the power button to get it back.I don't think it's over heating, or memory or any of that because I can happily play games hour hours with no issues.I can watch films,or streaming media for hours and it's fine. It only crashes while surfing or talking on Steam.
MSI P67C45 (still haven't got my B3 replacement :O)
i5 2500k (standard clock, with the 'turobo boost' ability engaged)
4gb (2x2) G.Skill Ripjaws X (I think. Can't remember freqs but I'll dig it out if somehow important)
Nvidia GTX260
Corsair F240 SSD (lucky competition win ) with the OS on
1TB HDD - got the pagefile set up on this drive so I don't burn the SSD

I recently got a Kensington HyperX SH100S3B/120G SSD. I've been getting these stange BSODs. It doesn't happen during any particular kind of activity, usually it's just browsing the web or writing documents or something.
Every time the BSODs happen, for some reason the boot order switches from the SSD to my backup drive, and I have to go into the bios and change it. But other than that, my hard drive seems to be perfectly fine functioning afterwards...what's causing this??
All my components are pretty new, so I don't think hardware failure is very likely here. I've thought maybe I should update my bios? But I'm not sure honestly. My mobo is H67MA-E35-B3 LGA 1155 H67 mATX Intel Motherboard.

My brother has been complaining that his PC shuts down randomly. I check the events log and find a very large list of critical Kernel power 41 errors, with no other error before them most of the times. I can't seem to find any pattern to them, so I asume it's hardware related. There's also nothing in particular he does that triggers it. I've runed memtest86 and AIDA64 stress test while checking temperatures with nothing strange, changed the PSU, formatted and clean installed Windows again,still the same. I'm about to surrender with this...

every time i try to install windows 7 on my new build, i do a clean install, however it spends about a second on the copying files part, then waits a few minutes before it starts expanding files. it hangs at 0% for a few more minutes then it will start accelerating. it will crash at random points while it is "expanding files".
the crashes vary, sometimes the display will explode and look lagged out then look like small tiles, the display sometimes turns red where shadows are as well, it also likes to just freeze. it frequently likes to freeze at 76 or 46%.
i had 7 installed one time when i kept my mouse moving constantly throughout the installation, but then the freezes would happen when i would boot into normal windows, but not safe mode.

I am experiencing some disturbing shut downs on my pc. This has been plaguing me for about 6 months now and I can't take it anymore. Just to be clear, these crashes do not provide a BSOD and therefore no error code for me to research and correct on my own. In the last two days, this has happened 4-5 times, and most often while watching streaming video online (but not always). Without warning, everything will lock up (sometimes this is accompanied by a terrible sound emitted from the speakers - presumably looping audio from the video i was watching). The computer then reboots itself without my involvement.

The computer then reboots itself without my involvement. Before anyone asks, my drivers are UP TO DATE, and my BIOS is up to date as well. So far, I have asked around and most people point to my graphics card overheating, or a very dirty (dusty) pc as a likely cause. Firstly, my computer is generally kept very clean, and I am monitoring my GPU temps and they are usually WELL within normal ranges (frankly it runs very cool). I have called EVGA for support, and they told me they had not heard of this problem before. They had me run a bunch of gpu stress tests, all of which provided no clue (they were clean) as to what could be wrong. Someone else told me to make sure my RAM was properly seated. I did check that and I can't see any seating issues.

Since about 4 months ago, my computer has crashed randomly. Every time this happens, I would try to reboot it, and it would start for between one second and five minutes before crashing again. It would continue to refuse to start like this for 10 minutes to three days at one point.It started four months ago, and occurs fairly rarely. Since the first "series" of crashes, it's only happened five or six times, with anytime between a week and a month separating the crashes.My computer has just crashed again, and as expected, is not opening right now, so I'm typing this from my tablet.if there's any specific information needed please tell me and I'd be happy to gather it once my computer decides to start up again.
Edit: More info - Windows 7, computer is about 10 months old, and I do this have a warranty on it. A curious note, the light on my wireless adapter remains on after the computer has crashes, whereas it would normally be off if I turned the computer off normally.Gives me the option of starting in safe mode, crashes there too. Usually it'll crash before the option is even offered. I've also tried plugging it into other sockets around the house, but still crashes.

Within the past week I've been getting numerous BSOD crashes. I've had some in the past that were related to the video card. Replaced the video card with a NOS replacement. That seemed to cure that problem. Three months later here I go again.
Here's what I'm runnng:
HP M9250F Desktop
Asus IPIBL LB Benicia MB
Intel Core2 Quad Q6700
4 gig of ram
Nvidia GeForce 8600GT
Haupauge NTSC and ATSC TV tuner

cpu i7 2720QM
gpu nvidia 555m
RAM DDR3
Main HD Crucial m4 128GB fw 309
Windows 7 x64 Professional
My PC randomly crashs without an apparent reason, one of the most annoying one happens if i leave the PC working without any input with power plan Balance, the screen is black and i can only reboot (doesn't happen with High Performance).However sometimes i also get BSOD while working normally.I'm also noticing how the frequency of the CPU gets really low sometimes if i remove the charger.

I have been having some computer crashes lately. They haven't been constant lately but it crashed again today and that motivated me to post this. I know that these crashes have to do with my graphics card. It happened to my computer with my old graphics card(fried) and it is happening about once time a month now. Basically what happens when it crashes is there is a notification on the windows task bar to the right saying something along the lines of "AMD display drivers has crashed". Any video I try to play will be messed up. Pixels are jacked up and sometimes the video goes completely green. If I see that notification about the display driver crashing, I have two choices. Play a video until my computer crashes or I can do stuff not related to gaming/videos and restart later. My graphics card is a Diamond Radeon HD 6670.

I think this all started after I did a RAM upgrade
It began with programs stopping (kernel32.dll, idon'tknowthenameanymore.dll)
But also games are just freezing after some time, mw2, ac, cod4. They all crash randomly.
Now sometimes the whole system freezes and I have to reset it.
Also, I get various BSOD's (ie IRQl not less or equal)
I think it has somethin to do with my memory,
I have 4 gb dual corsair 1066 kit combined with 2 gb Reaper 1066.
I am thinking of re-installing windows, because I didn't install it after the upgrade
Or do you guys think that the memory is corrupted?
Specs:
Win7 ultimate x64
