Windows 7 Crashes / Freezes With Artifacts (Wavy Colored Lines)
Jan 24, 2012
I've been using my PC fine for the last 3 years. A month or so ago I updated to Windows 7 Ultimate x64. That too has been running fine, then today, after about 3-4 hours of use, in the middle of a game, my PC screen suddenly got weird wavy lines and colours all over it and crashed. Long story short this has now happened about 10 times. Interestingly, I thought it was a graphics card problem, so I tried it on my HD TV (both TV and monitor connected via HDMI) and it did it on the TV too. I then uninstalled the nvidia (8800gt) drivers and restarted my PC. It works fine in safe mode, and in normal mode, but I can't change my resolution to 1680x1050, (it's native resolution) without installing the nvidia drivers.
I don't know if the problem is the drivers, (but never had an issue before?) or with resolution, (monitor problem?) Every time I do install the nvidia drivers the PC restarts normally, screen looks fine, and the PC seems to run, until I click on anything with the mouse and then the wavy lines and weird colours appear again and I can't CTL-ALT-DEL, I have to hard reset it every time. Once I left it for 5 mins. and moved the mouse a little every min. or so and that was OK, but as soon as I click on anything, it freezes and artifacts again. Also, my antivirus flashed red a few times and so did the windows clock in the bottom right corner of the screen, (very odd!) when the PC first starts windows.
That made me think it could be a virus, (even though I'm very careful about what I DL), but I had Avast run through a deep clean check and it found nothing. I also tried to get Win 7 to repair itself, which did nothing either! I've tried reinstalling the drivers, using newer and older nvidia drivers and I've tried to install my HG216 monitor driver, but since it's a few years old there is no official Win 7 support and all I have is an inf. file I can't install on Win 7. I haven't included a dump file, I know a fair amount about computers but I haven't worked out how to do that yet. Also, since I have to hard reboot everytime, in my event view the only errors listed seem to be about 'power failure', so I don't know if the bug or whatever would show up in the dump file?

I don't know if it's drivers, or the monitor, or something different. I only see the lines when windows is running (I do not see the lines in BIOS). The lines somewhat change when I change the refresh rate, however they always come back (and they're always there no matter how small, or large the lines are - they differ).
(It is sorta like a fuzz, but they're lines moving everywhere) (If I put my desktop background as a darker gray, the lines sorta look darker purple if you pay close attention) [URL]
(the image is taken from a cell phone because I wasn't sure if the lines would show if I took a screenshot, seeing that I do not know the problem)
I have also provided an image which shows my specifications of my computer: [URL]

I built up a PC a couple of months ago. It has an ok spec, Phenom II 550 x2, NVidia GTX 250, 4b ram, 500gig HD, 620w PSU. Windows 7 Eval. 7100.
From the first couple of days I noticed an issue that looked like incorrectly setup refresh rates - there are wavy lines accross the entire screen, and is particularly noticeable on highlighted text and the side edges of windows. I made sure the frame rate was correct, both in Windows and according to the GFX Card. I have tried all the settings but have settled at 75hz. This is the best setting but does not get rid of the problem.
I have the most up to date drivers for my GFX Card and Windows 7 is up to date too.
The intensity of the problem can fluctuate. Right now, its fairly minimal and only visable if you are looking. It can however get to the point where its becoming hard to read text, or at least tiring because you have to strain some more. This can happen at any time. The only link I have found is to games, as both World of Warcraft and Borderlands will intensify the isse, both ingame and in Windows. I am fairly sure they are set at the correct resolution and refresh rate where possible.
What could this be?
Further info, three weeks ago I turned the PC on in the morning to find the 'power' button unresponsive. After some waiting and several attempts it eventually turned on but I got a 'no signal' display on screen. Later I resorted to jump starting the PC without the power button, using a screwdriver to connect the prongs - after doing this, the power button has been fine although it took another day for the no signal message to go away and normal viewing return. This problem has not repeated since.
During this the fans were fluctuating a lot, audibly so. This dissapeared mostly along with the above problems, but I still think it sounds like the fans are fluctuating infrequently, particularly on initial bootup. I have no software for changing fan speeds, as far as they know they run at the speed I set physically.
A lot of this seems to point at the GFX Card, although I am a little more inclined to think it is the power supply, or the availability of power for each unit. But I really don't know. Either I can find the solution online or I take it to the shop and pay for a repair, not that its easy to even tell them what they need to repair.
The PC runs fast and with relatively few crashes besides that one weekend and this persistant display problem.

My mom has a Compaq laptop. It has Windows 7. Yesterday, the screen randomly turned a blue-ish green color. The Google Chrome new tab page is where she first noticed. It's pretty much wherever there should be white, there's that funny color. When I restart it, the white Compaq "Q" logo is green instead of white. The "Starting Windows" text is green and the light inside of the Windows logo is green also.

OK, just woke computer up from "sleep," and everything is working fine. A few minutes later, all of a sudden, the monitor screen is filled with colored vertical and horizontal lines...and nothing is working nor is there anything else on the screen but the lines. Manually, shut down and rebooted. Opened with options on how to continue. I chose Normal Mode. Computer and screen now working as they should for the last hour.

My Gateway runs great until a restart is requested by me or a program. A few days ago, it would restart just fine. When I select Restart, the computer appears to shut down fine, it beeps to restart, the Windows 7 screen begins to open but it freezes with three colored dots on the screen. It always stops in exactly the same place.
If I kill power, then boot again I get an offer for Windows to repair itself. If I let it, it cannot repair. If I select Boot Windows Normally, all is well. Except for this one problem, things are really running well. Odd. I've run Chkdsk, SFC/ SCANNOW, and PC Pitstop Optimize3. Nothing finds a problem or fixes anything.

The windows logo on the loading screen doesnt show. So the first step I tried was trying to boot into safe mode but there is problem one. I cannot boot into safe mode becasue whenever I hit F8 it does nothing and just boots into windows like normal. I know my keyboard works because if I hit F12 to list my boot device options it works. So since I could not boot into safe mode I used my win 7 dvd to try a system restore. That didnt work, neither did the repair windows startup option. After all this I took my hdd out connected it to my laptop and then ran a check disk. It didnt find a errors just missing files.

I've posted about this issue several times and still have not found a solution unfortunately. I have Windows 7 Ultimate 64-bit installed on my machine and I experience freezing and BSOD errors very frequently. The freezing occurs way more often than the BSOD does (by the way I would include a mini dump file, but there are no recent ones). The freezing is what's driving me mad as it happens all the time.
Just to rule out a few things, here is a brief list of solutions I've tried:
1. Updated all my drivers first and foremost.
2. Changed my power options from balanced to high performance.
3. Installed ALL motherboard drivers (chipsets, etc.) and flashed my BIOS to the most current update as a person on this forum told me to do so.
Also, the freezing usually seems to occur during some kind of activity involving the internet such as watching a video, playing a game, browsing a web page. It's pretty random actually, sometimes it will just freeze at the desktop. Recently it's been freezing when the computer has gone idle (when the screen goes black) after a while.

Since today, I've been having random freezes in Windows 7. When it freezes, all I can do is move the mouse cursor, windows explorer happens to be crashing at that point & there is no way for me to ctrl-alt-delete or ctrl-shift-escape myself out of the situation. I have to restart the PC only to be confronted with the problem again shortly after. These freezes happen at very random times. For example when I opened up the start menu and typed "cmd" and pressed enter, it froze.
Or just when I simply started up my PC and when my first action was pressing "Cancel" in an application window, it froze as well. It also froze just opening the start menu & froze opening my User (Tom) folder. I decided that it might be because of some update or one of the applications I've installed since today, so I decided to do a system restore to yesterday, which removed those applications. This however, did not fix the random freezes. I also checked my PC component temperatures in the ASUS BIOS, they happen to be fine. I'm on the PC right now, it runs fine in safe-mode.
These are my specs:
Windows 7 Home Premium 64-bit
Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz, 3411 MHz, 4 core(s), 8 logic processor(s)
AMD Radeon HD 6700 Series

I am running Windows 7 and frequently get a screen freeze while playing Battlefield Vietnam II or Battlefield II only. This happens quite often and I see no patterns except for these 2 games. I have updated my video drivers. I have an NVIDIA GeForce GTS 250 (Prerelease - WDDM 1.1)

I downloaded windows 8 consumure preview and I wanted to reinstall windows 7 so I get my windows 7 disk and hit reinstall.

Windows installation cannot proceed. To install windows, click ok to restart the computer, and then restart installation". I hit ok. It restarts and the same message pops up.

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 recently reinstalled my OS and installed the AMD Drivers for my 5830s(crossfired) and they seem to be causing freezes. By freeze I mean that my computer will lock up completely and I cannot move my mouse and I have to then hard restart.
I have tried several solutions, such as reinstalling windows and reinstalling the graphics drivers after removing them in safe mode with driver sweeper. I have tried old versions and the latest versions do not install. I can boot into safe mode successfully and that is how I am asking this.
My Computer specs:
AMD Phenom II X6 1050t OCed to 3.2ghz
8gb of Corsair XMS3 RAM
2 XFX Radeon HD 5830s Crossfired
850W Power Supply

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?

My Asus G73-JH laptop is currently freezing at the Windows Starting screen. I've read a lot of other forum posts that feature the same problem, BUT there is artifacting (bunch of colored dots) on the top of this screen that goes across the "Starting Windows" screen in a sort of horizontal line. Sometimes it just goes straight to the "Windows has failed to startup" screen. None of the System Recovery Options from the Startup Tool seem to help fix the problem, they've all been tried. Trying to boot in safe mode doesn't work either, as after it starts to load the files, the artifacting appears on the top again after about the third file and it freezes.
I have not made ANY major changes to anything on the system for over two months prior. Because of the artifacting seen, I imagine the video card is fried or malfunctioning. I called Asus and all they suggested to me so far was to reformat, because apparently they think its a driver issue, but I'd like to consider myself fairly tech savvy and believe that there has got to be a better solution that does not involve reformatting the hard drive, as I had a lot of important data that had been stored and not backed up the previous night before the unexpected freezing. The only things I seem to have access to is BIOS and the Startup Tool. I have a System Recovery Disc too, and am curious if there is a solution to this problem (I am not well versed in BIOS), and (assuming the video card is shot) if there would be a way I can access by data and possibly back it up before reformatting so I can persuade Asus support that my card is in fact shot so I can send it in for a replacement!

I recieved my Sony Vaio Windows 7 disks today, put the first one in and it started doing some install thing for supplement disk (said 1/12) but then froze for ages, so I tried closing it. When I attempted to start the installation again, I now receive this error:"The supplement disk utility has stopped and cannot continue because the main C: drive partition information is not avaliable. Restore your computer to the original factory settings and try using the supplement disk utility again."

I have an HP desktop x64, win 7 32 i just did a factory restore 2 day ago but, I still have 1 of the problems I had before; the mouse on my computer will freeze for like 20 sec and sometimes causing the system to crash. Yesterday, it shut down on me and a blue screen popped up it said something about the drivers or bios but, I checked the maintenance and it said everything passed (good).

My computer has been crashing a lot lately. Usually, the computer freezes and weird lines appear on the display when it happens. Other times it just shows a BSOD and restarts. It started happening around 2-3 weeks after my motherboard, processor and RAM were changed because a part of the previous motherboard had burnt. The previous motherboard was ASUS M3A78-EM, the onboard graphics was ATI Radeon HD 3200 and RAM was 2 GB DDR2.I took the PC to a my computer vendor after everything I tried had failed. Firstly, he diagnosed it as an issue because of improper earthing/grounding in the switchboard where I plugged the computer and the UPS. I got the earthing issue sorted but to no avail, it still hanged/freezed. The second time I took it to him he said that he might have to update the BIOS and when I brought it back the problem had apparently been fixed but that was only for a few days. After like 4-5 days it started happening again. Same weird lines - green, magenta, purple and all the rest of it - started appearing. The HDD LED stops when this happens. I only observed the LED today, though. Today the computer freezed without those weird lines on two out of the 5 or 6 times it happenrd, it looked like it had just hanged but the HDD LED had gone off.Sometimes the PC doesn't start up at all immediately after it has crashed. That's what led me to guess it's a hardware issue. Also, it happens in safe mode and Windows XP too (I dual boot Windows XP and Windows 7) and I remember it once happening even before the computer had completely booted.Computer details:Windows 7 32-bitASUS M4A78LT-M-LEAMD Athlon II X2 250ATI Radeon 3000 onboard graphics1 x 2 GB DDR3 RAM250 GB SATAMinidumps and NirSoft BlueScreenView HTML report: url..
