| Walter All-Star Member 1445 Posts 3/05 | I have a screen freeze problem on my laptop. I have had Vista 32 bit for roughly a year and have not had this problem before. The Vista screen freezes while I am working, The only solution for me has been to shut the computer off and then turn it back on. This has been occurring for a few months. I am wondering if this could be caused by some sort of memory issue. To test this I made some observations with Task Manager. Yesterday I turned on the Task Manager after I had recently restarted the machine. I saw the following at that time: On the Processes Tab: Firefox using ~92MB of Memory (Private Working Set) Host Process For Windows Services Using ~41MB of Memory (Private Working Set) Desktop Window Manager using ~15MB of Memory (Private Working Set) Microsoft Windows Search Indexer Using ~12MB of Memory (Private Working Set) 75 other processes all using <10MB On the bottom of this tab, it indicates that I am using ~3% of my CPU right now but 45% of my physical memory. The performance tab indicates that I am using ~900MB, which is 45% of 2GB, which is the total amount of RAM on my machine. However, I am only running FoxPro right now. After making note of the above, I left Task Manager up and left my computer for a few hours. When I came back, the screen was frozen and Task Manager indicated that 54% of my physical memory was being used. It seems that a process called the defragmenter was running when I came back that was not running when I left. It did not appear to be a huge memory hog. I am not an expert and any help or explanation that could be provided here would be greatly appreciated. Is there some sort of memory problem here? PS I have 2 co-processors, if that matters. PPS I have done many antiviruses, antiMalwares, antiSpyWares, etc... type procedures. They seem to indicate that my machine is clean. I also ran memtest and id not find any errors. Thanks! [Link] |

Check the Task Manager in Safe Mode and see if anything abnormal is running. Almost nothing should be running in Safe Mode. If none of this works, the odds are that you have a serious problem with the computer. It could be the mother board or some other hardware issue. As far as software, have you installed any new program very recently-around the time this started? I'm not a Vista user, however, I do know that there is a major issue with Vista. What video card do you have installed? If it's a Nvidia video card that could possibly be the culprit. It seems that the ones they made for Vista has major problems. Microsoft has accused them of ruining the name of Vista by having faulty video cards that creates various problems. There is even a class action suit against them by a shareholder for an abnormal failure rate. If I were you, I would contact the manufacturer to see what can be done-especially if you're still within the warranty. It's always good to purchase an extended warranty for computers. |

| Jordan1 Member Fishing, a fun hobby! 490 Posts 7/08 | If my memory serves me, the quickest and easiest way on Vista is to right-click on the Desktop->Personalize->Display Settings. It should tell you what the Video Card is, e.g., Nvidia GeForce XXXXX. It's also in the Device Manager which has other info about the PC. I think you right click on (My?)Computer-left-click on Properties->Device Manager tab. After clicking on Device Manager there should be a list. Click the + next to Display Adapters and it should tell you what Video Card is installed. If u let me know which one it is, I might be able to help you find out if that Video Card is on a list of defective ones causing crashes or freezing. If there is such a problem, the manufacturer is obligated to fix it at no charge. Sometimes the bastards will try and dupe the public and hide a known problem so they don't have to recall and fix the tons of faulty PC's out there. I know there is definitely a problem with Vista notebooks and Nvidia Video Cards. |

| RandomPrecision Senior Member Enjoy! 8175 Posts 3/06 | Edit - Just make sure you have access to another computer with internet access before you do anything. There shouldn't be a problem but if there is, it's really helpful to be able to get online and find some help. Edited by - randomprecision on 4/22/2009 6:50:41 PM |
| Hardware All-Star Member Your other left 14606 Posts 3/02 | My guess is that you have automatic updates enabled, so it is possible that the problem was a faulty driver, and an update was installed a couple of days ago, thus automagically correcting the problem. That is certainly preferable to the other common causes of the problem you describe, which are a bad solder joint or a cracked motherboard. |
