Performance Issue, Glitches, Blinking, Cpu 100%
Nov 28, 2009
Too many glitches(windows, icons, everything blinks at different times and sometimes just after blinking for a while, they go black and as soon as I get the cursor over it it stops). I have a CPU meter and is running all the way to 100% almost all the time, with any Program, window opening or task that I try to perform. Because of that is running extremely slow.
I am not a computer expert as I see most people are in here, so instead of trying to fix it my self and making it worst. I took it to "Geek Squad", in Best Buys, to get it fix, and after 2 day with them they told me that there was nothing they could do. They did see the problem, but they didn´t know how to fix it.

This is the second time in a month I have encountered this glitch. I have had my laptop for 3 years and have just started getting it. I have an Asus G50VT-X1. It seems at a random time the screen just bugs out and the colors change and shift. There are also little block artifacts everywhere. I can move my mouse for a bit, but then it completely freezes.
I know it's not a hard drive or OS thing because although the first time it happened I was on my HDD, this time it happened on my brand new SSD that I just installed with a clean install of Windows 7. I've asked my friends about it and they said they have never heard of it happening before. I have the latest drivers from nvidia, so that can't be it.

System Information:
OS: Windows 7 Ultimate (6.1.7601, SP1 Build 7601)
Data Type: x64
DirectX Version: DX11
[code]....
I built this computer myself, I have upgraded the Video card about 3 times since I bought my motherboard. When I bought the motherboard, I also bought the CPU, SSD, RAMs, and Power supply.I haven't changed any hardware, except for the graphics cards. My problem is that an almost random set of games crash for no reason, even if the game specs aren't as high as others I play flawlessly. For instance, Dragon age origins (not a big performance issue), Batman arkham assylum, Bioshock 2, and Assassins creed Revelations- they all crash to desktop after about 5-15 minutes. Other games I play relatively fine are, Assassins creed 3, Planetside 2, Starcraft 2, Borderlands 2, Mirrors edge, all with max settings they work. All of these vary in system requirements, but as you can see, there seems to be no pattern.This would be fine if I could read any temperature meters, but it's impossible when it crashes. What it looks like when I'm playing is nice clean FPS as usually, then by suprise it overloads with sound (only some games), the polygons stretch, and I hit the desktop. When I hit the desktop, things are glitchy, certain areas are black squares (ie. random menu buttons, temperature readings, some, but not all buttons are black, but all readings are black). Any games I try to start up after this just don't start up. I am forced to reset, and my computer acts like nothing happened.
It rarely happens on my favourite games, it seems like whenever I buy a game, it's a lottery if it will crash within 15 minutes. If it doesn't crash within 15 minutes, it will rarely crash ever. My computer has a good taste in games though, I like that, but it lashes out on me if I try something new and it doesn't like it.I keep thinking it's my CPU, because my graphics can set themselves amazingly high, and I've changed it so many times, I think my graphics card is ruled out. Do I have to reapply the thermal paste onto the CPU? I might find some additional readings and post it here, when I get some time.
Is 650W high enough for a PSU?Are these crashes damaging anything but the part that is causing it?Are there any updates I've missed?How do I know if my computer has good enough airflow? What kind of adapter do I have to get to connect my USB 3.0 cable to my motherboard? My motherboard has 3 blue (3.0) 9pin slots, but my case has a 19pin 3.0 usb cable.

I recently put Windows 7 Ultimate (32-bit version) on my Acer Aspire One AOA150/ZG5. It runs but when I go to download something I often get a BSoD (not always however). I was wondering if this is a driver issue and if there's a way to fix it.Everything seems to work (except a few features on the mouse pad and I'd assume the webcam).

I'm using; Emu 0404 Usb Sound Card, M-Audio Radium 61 Midi Keyboard.
This system worked good on Windows Vista (32bit) with no audio problem or latency problem.
The system works great and faster than Vista on Windows 7 (32bit); but now with audio clicks,pops,latency problems and etc..
I'm using DPC latency program.. It shows red coloumn in every 3 or 4 secs. I tried to disable USB mouse, wireless etc.. but nothing happened. Also I updated all my drivers too.

my problem started after running the following dxsetup.exe, which was required to play a mod for the game morrowind (apparently some files were missing from the most recent versions of dx): (url) everything seemed to work fine after this. i played the mod for a while, then yesterday i decided to buy deus ex: human revolution. again, i installed, the game required a dx update which processed fine, and i played the game for a few hours and went to sleep. the next day, my problems began. i noticed Internet, livestream, own3d.tv, or any web video player would crash after a minute or so. the video would stop, the sound would stutter and distort, and i get a brief black screen and a then the video player restores with a green screen instead of the video playing, and in my task menu a pop up occurs with "nvidia kernel 180.26 has crashed and successfully recovered"

To reinstall windows 7 you just need the disk . Try updating your BIOS first your system should play crysis 2 smooth as butter . After that I would do a fresh install of window's 7 go into your BIOS select you dvd drive as first boot choice save and exit .put the cd in the drive and restart your pc don't forget to press enter !

Alright, so recently I upgraded my windows vista laptop to windows 7 ultimate.Everything ran smoothly, except for now when I type, it will randomly act as if I am holding ctrl for short bursts, opening new tabs, windows, closing the browser, opening the find window, bookmarks window, etcIt never did this before I installed windows 7, and I checked to make sure my drivers are up to date, which they are. I've googled and tried many solutions, but none of them have worked. I am running windows 7 ultimate 34 bit on a Toshiba laptop, but that's all I really know.

I have been having random graphical issues. Sometimes in games (ie. COD4) the screen goes black when a new map loads. I then have to exit the game and reboot the PC, hoping it fixes my issue. Also, since I updated to the latest version, there are random graphical glitches in the game (weird objects on the ground and in the air in the game). Now the issue is much worse:
When I boot up my PC, my taskbar is completely blank, except for the Start Button. I'd be willing to deal with this issue if I knew how to fix it when it pops up. I uploaded a screenshot here: [URL] I'm running the latest drivers from Windows update from Nvidia. My motherboard is the EVGA Nforce 680i.

the screen glitches with pink, white, and green tiles and lines, the cursor disappears, the screen goes black, and the hard drive stops spinning. All the lights on the front of the computer stay on, the fans stay on, and the monitor doesn't say anything about not receiving a signal. The first time it happened I tried turning it on right away and it booted up and let me sign in, but as it was loading the desktop and icons it glitched again, and froze. after I shut down and let it sit for a while it worked just fine until the next day when it did the same thing again, but twice in one day and with a shorter time between freezes. Today I had a WerFault.exe error pop up and when I clicked ok on it the bottom half of my screen turned pinkish and the computer froze when I restarted the pink tone was still there but it did not show up on any windows that I opened and when the background changed it went away.

Yesterday, I noticed my taskbar acting strange. I was using Firefox at the time, and my taskbar would just start blinking rapidly.Right now as I type, my screen is blinking, my taskbar is flickering rapidly, and the icons on my taskbar are enlarging quickly. This happens when I am not in firefox though.I booted into safe mode and ran a full scan on all my drives and got nothing.This pretty much started happening randomly. I don't remember installing any new software, drivers, or updates before it happened. After it happened though I did install about 90 windows updates.i also get graphics glitching in all games.In HL2, the video in the main menu turns to random colors and while actually playing the game, all props starting flickering like crazy.In Oblivion, the loading screen got distorted near the top among other things.

I have recently obtained a laptop with Windows 7 Home Premium installed. This is the first time I'm using Windows 7.My HDD light on the laptop keeps blinking, even when I'm not doing anything, just staring at the desktop. I don't notice anything on the performance, everything seems to run fineOne thing I was immediately aware of is how Windows 7 seems to run a lot of processes in the background; indexing, defragging, etc... I have turned these off, along with stuff like WDefender,Firewall, my hdd light still keeps blinking.I have also noticed that googling this issue reveals lots of results with mixed replies. Some say HDD light is supposed to be blinking and/or this is completely normal, others say it might be an issue.Just as I was writing this, I also downloaded a gadget for monitoring hdd: Drives Meter. Looking at the graph, the hdd doesn't seem to be doing much. It usually stays on %0, just some little activity here and there... Yet the light is blinking on a heartbeat rate. Bear in mind, I am running Comodo+Eset at the background; however, for comparison, on my PC (running XP Pro) which also runs Comodo+Eset, there is no blinking whatsoever.

Well, I think we might have a new one, I looked back a few pages in the whole list of topics.
My wife's computer is using a fresh install of Windows 7 build 7000.
This problem seems to happen randomly and we cant find a rhyme or reason to it. At first I thought it might be a heat issue, perhaps with the video card. Well about 4 months back(the blinking problem was not present at this time), I found her video card's fan had stopped working and we replaced the card with a new nVidia 9600GT.
The blinking started maybe a week or two ago.
Rebooting the computer does not help in most cases.
Placing my monitor on her computer was inconclusive. It did not blink.
Placing her monitor on my computer was also inconclusive. It did not blink.
Right now she is using a driver that is dated 4/2/2009. We are currently downloading the driver for 4/30/2009 hoping this will help, and once it is downloaded and installed, I will write back on my findings. Maybe we should update to the latest build of 7?
If I'm in the wrong forum, or location or if I missed a post regarding this same issue, please let me know so we can get this figured out on our end.

About a month and a half a go my laptop was infected with 2 trojan viruses and ever since I haven't been able to start it up as it stays on a black screen with a blinking cursor after the toshiba splash screen. I am able to use my computer by booting with Hiren's boot cd and have since cleaned up my computer and gotten rid of any viruses..but have to continue booting via disc and it is getting sickening to do so.

I was installing 7 on a friends laptop last night, everything was going fine, however after the installation has finished, upon turning on the laptop, windows does not boot. In the top left of the screen is a blinking command prompt like icon. Cannot type/ do anything from this point. If the 7 disk is in the option to boot from disk comes up, but this leads straight to install windows. There is a repair option, and it will allow me to scan for start up errors, but none are found. It also says windows 7 is definatly installed on the C partition.

Almost every time I click (Open windows, maximizing windows etc, etc...) The whole screen will blink and I will see a brief (Not Responding) which only lasts for a split second, then I can resume my work, in the worst of cases this can happen 9 or 10 times until the computer actually responds and selects what I want it to.I have recently upgraded my graphics from a ATI Radeon X1200 (Old and useless) To a NVIDIA GeForce 7300 SE/7200 GS. ALL of my drivers are up-to-date and a system restore is not an option.

I have been using my emachines netbook 350 for a year now and running windows7 in it since I bought. A month ago, I've started seeing those blinking horizontal lines on my screen. Almost half of my screen is affected. I wonder if it is a problem with my video card or just some viruses. Well when I print screen, the lines are not showing. The same as when I connect my netbook to a projector

I just rebuilt my computer, but reused my old WD HDD, OS and all. It used to be hooked up to an AMD rig, but my new CPU is an i5-2500k and mobo is an MSI P67A-GD53 (B3). So when I hooked everything up and booted for the first time, the computer showed an error saying that the memory or cpu had been changed and that I needed to run the setup, which I did. That led me to the blinking cursor on a blank screen.It stayed that way for several hours before I decided to reboot. That time "A3" "99" "B4" flash on the screen, then it goes straight to the cursor. So I decided to give a new hard drive a try. I went out and got an SSD, hooked it up, same problemMy best guess right now is that the mobo was DOA. I'm still kinda new at this PC building thing

My problem:-Computer restarted itself while I was working (I believe I had awindows update installed, and it restarted by itself)-Rebooting never gets past the Gateway logo.-What I see: Blinking cursor, even AFTER pressing F8.What I did:I tried F8 (to get into system restore) but all I can do it so into F2 and F12. When I press and hold down F8, the computer beeps 3 times. After that, any key I press will beep.My computer:-I have a Gateway netbook laptop, running on 64-bit Windows 7-I do not have a CD-ROM drive in my netbookI do not know what to do.

I am having a major issue with my laptop! First, here are the specs:
HP G60 Notebook PC
Windows 7 home premium
Pentium Dual Core T4300
Total Memory 3072 MB
BIOS version F.53
Just recently i got a virus and since i dont have much money i didn't have protection. I used my system restore to get past it (not the first time i had to do this). I dont remember if i was able to use the laptop after that or not, but it was only a day later that i noticed the laptop wouldn't boot into the OS selection screen (I had Ubuntu installed also, so i had to select between that and windows 7). At any rate, i will press the power button, then it has a screen that shows HP's logo, then changes to a blank screen with a blinking white underscore in the top left of the screen.I reset, then pressed ESC immediately on start and ran a few tests by selecting "System Diagnostics" which is selected by using the F2 key.
100 percent of system memory tested OK
Hard Disk passed Quick Scan
Hard Disk passed Full scan

So I installed Windows 7 on my HD. The installation process went well. I chose my Username, password, etc, and then Windows prepares the Desktop for the first use, and then the PC automatically reboots.
The problem is that when the pc reboots after the final stage of the installation, Windows won't boot up and I get stuck with a blinking cursor. The only way I can boot up is when I turn on the PC and keep pressing F5 and then it takes me to a GRUB 0.4.4 Red Window like this one
When I chose the "alternative method", Windows boots with no problem. Is there a way to choose the alterative method as the default?

About two hours I was doing a recover in my hd (with Acronis true Image 2010) when at 1/3 of the process the computer rebooted. I thought it was normal, but soon after the image of the motherboard appeard, a blinking underscore emerged and the boot does not proceeded. I have tried changing the boot to dvd and hd (in the bios), also I tried to put the windows disk but the option to boot from cd does not appears. ie, the PC starts, the image of the motherboard appears and then immediately the undersore flashing.

I upgraded to Win-7 64 bit and now my mouse cursor blinks with the busy icon about every 6 seconds. I also see the processor is running at a constant 4% to 6%.
When I had Vista the solution was to disable the HD Audio device and it solved the problem. Now this isn't working at all.
I also installed a new video card: ATI Radeon HD 5770.
