Hi, I have an issue with Vista whereby after around half an hour of use, everthing seems to lock up. The HDD light stops flashing, but I can still move the cursor around, although it has the blue egg timer hoop thing rotating. The hover over still works on the icons, but I am unable to get into task manager, click on the start button or open any applications. CTRL+ALT+DELETE does nothing. Sometimes, if left for around a hour, it comes back to life, but in most cases, a hard reboot is the only thing that will sort it. When it restarts, often it will run through disk checker and sometimes finds faults with $I30, whatever the hell that is. The problem does not seem to occur after using a particular piece of software, or at a particular time. There is no slowness otherwise, its really quick most of the time. Things tried so far: 1). Re-formatted and re-installed Windows: Worked fine for a while, but as soon as I start to use it regularly, the issue returns. 2). Made sure all of the updates were on, did antivirus and anti-spyware scans. Found nothing (The laptop is only a month old and has hardly been used) 3). Contacted Dell Support (Useless patronizing nonsense suggestions on a premium rate line). I've tried to rule out overheating too. I have an Antec laptop cooler, which I always use. Laptop is always cool to the touch all over. I've figured that because Vista seems to be working in the background on something, that it must be a program that has locked, but I can't tell what. I really can't see why there is no facility in Vista to auto-eliminate non-responsive or programs needlessly hogging system resources or at least record their activities?? Are there any applications which record system activity up until the point of lockup, so I can identify the problem?

Go to Control Panel-System-Performance-Manage Startup Programs Do Ctrl-Alt-Del to access task manager and see which programs, tasks, etc. are running.

It could be your AV scanning in the background & hogging up resources -- what do you have? Jabbering Idiots: Everywhere You Look!

Yes, this was my initial thought. The laptop originally came with McAffee (Trial Version). Since I have reformatted it, i've been using Avast home edition instead. I have looked at the event logger, but this does not tell me what program stopped responding. Are there any other programs which record processes, so I can identify the problem app upon it hanging? Or a program which monitors/restricts how hungry certain apps are for resources? I wouldn't mind as much if I knew what was running at the time, and that it was actually busy doing something useful. The blue timer rotating, doesn't give much of a clue by itself. I'm frozen out of the system at random intervals wondering whether it has plain stopped responding or not.

Using Task Manager/Processes isn't much help. Firstly because I cannot access it when it locks and there are 20 or so processes, so there is no way to be sure which one is causing the issue. I could do with something that creates a log file of the running processes, so I can go back to it and look at the last process to run before it locked.

Does it freeze in safe mode? If it does not, it would indicate a software. Post back to let us know if it does. BTW, you could try Process Monitor if you found Task Manager lacking. Although, it may not serve its purpose if the machine is likely to lock up after few minutes. http://technet.microsoft.com/en-us/... Jabbering Idiots: Everywhere You Look!

Check the Event Log for errors or warnings. Look under the System section. When it locks up like that, note the time on your PC's clock that it did so, and find the event that is nearest to the time that it locked up. Personally I suspect that your hard drive is failing. Maybe you should take back to where you got it and have it exchanged. WinSimple Software
