Randomly Powers Off Without Warning.
Aug 12, 2009
My Vista x64 PC is randomly powering off. MSI Neo4 Diamond MB, AMD athlon 64 X2 4200+ CPU, 2G ddr2-800 ram, 1TB and 500GB SATA drives, ATI Radeon HD4350 video card. started a couple months ago. either you get into Vista and are working and suddenly pow... it goes off like pulling the power cord. sometimes it will do it right before the screen gives you the login to Vista..Thought it was a power issue and upgraded a 500W supply to a 750W modular unit. No change... have completely disassembled the unit, cleaned everything, cleaned the CPU/heatsink and put new Arctic silver in.
I can sit in bios all day watching the hardware monitor and the CPU never get's over about 30-31 Degrees C. Voltages are good and steady. as soon as it's booted to Vista, it starts... even sitting idle it will do it. I have Windows XP and Windows 7 RC on the 500G drive. if I boot to either of those OS's, it will run for days without ANY issues... it is ONLY vista that has the issue. I thought it may have been the drive, so I made an image and restored it to the 500GB drive, then removed the 1TB drive from the system... Same issues.

Basically Since I've put in a temperature gauge for my Kandalf case it's now will not shut down. well it does shut down and powers off (i also have an intellipulg thing but i'm sure thats fine) everything goes off monitor pc all the lights inside etc... then about 10 seconds later it just turns back on. Can't see how the temp gauge has done this as all that does is gives a display and takes one power molex so can't turn it back on. Have made sure that it's not on wake on lan/wireless. and turned off wake on usb keybored etc.

I cannot get my Vista box powers options mode to go to hibernate. It's simply no longer listed as an option. It once was. Also no "Hybrid sleep mode" listed as well. Once was. Looking over the web I see people use the cmd line with:-
powercfg -h on
When I do this I get a message:- "You do not have permission to enable or disable the Hibernate feature." I am the only user and I have administer status. What gives?

Vista Ultimate with all the latest service packs and updates install, then installed IE8 RC1.
Installed Internet Explorer 8 Release Candidate 1 and had the following
problems.
(1) Windows would not restart.
(2) required going through Safe Mode startup to get Windows to finish installation.
(3) after rebooting several times, finally got it going.
(4) Aero was turned off after all of this.
Not sure if it was a remnant of Safe Mode or from IE8 RC1.
Note: If you have to reboot, then turn off the PC. Unplug the PC or turn the power switch off on the back of the PC on the power supply. Sometimes just using the buttons on the front of the PC does not remove all power and thus all facilities.
I have seen this many times; demanding a complete power removal before the PC would restart properly.

I've been running Vista Home premium for a couple of years. Over the past months it has started to slow down, with warning about low memory (2 gig RAM). I defragment quite often.

My father and brother both use internet mail and when they send any emails on to me in Vista mail I don't get the attachments (one was a .wmv ext) As far as I know I have checked/unchecked ALL the correct boxes in the mail options and my Avast online scanner settings and still I don't get the pictures intended or the attachments. I have removed Norton, checked my firewall settings and still nothing!

They have done it again. Microsoft geeks take a perfectly goodproduct Internet Explorer 7 and mess it up. They just can't keeptheir dirty little paws off that source code, can they? The URL dropdown now gives you an assortment of locations on your hard drive, something like Windows Explorer.

Whenever I try to convert an .avi file to DVD format, my PC starts the conversion process, and then suddenly shuts down. I'm not sure if this is a Vista problem, or a hardware one, or a ...? I'm not sure what the problem is, but I'm wondering if there's some kind of fail-safe, a breaker of sorts, that shuts the PC down when the cpu usage is above a certain level? The PC does get extra loud when it starts the conversion, so my guess is the processor is really being drained. But if that's the case, shouldn't a dual core processor be able to hand a simple video file conversion? Am I making any sense? Probably not. Is there some kind of test / check / diagnostic tool I can use to assess what's going on?

I have a Vista Business from technet that had reached the end of activation, before I had the new key to reactivate it. Inserted the new key and reactivate, all ok, but I have still a warning that it remains 0 days to activate and the pc rebots.

WARNING!! Vista Windows Genuine Activation (WGA) Problems: Genuine Microsoft Software Advantage. There is a problem with Microsoft's WGA servers and they are not allowing Vista to be activated as Genuine.
Do not do anything that would require you to reactivate or validate Vista. EX: Windows Updates, Hot Fixes, Activation, etc. Wait a week before trying again to give Microsoft a chance to sort through the problem. If you do not, you will be left with a Vista that is considered not Genuine. If your 30 day trial period is almost up, or you are already in Reduced Functionality Mode, then see: - Read Tutorial

Do you know how to get rid of the annoying "wireless mouse battery level is critically low" popup? This is a ms wireless laser mouse 5000. It just started doing this about 6 weeks ago, before that it was fine. Did an update install new driver software or something? I just want to get rid of the popup, the mouse works okay.

I have disabled UAC on a Vista machine so that I can connect to it from a remote location and change its configuration. However, every time the Vista machine is restarted a window opens above the tray telling the user that UAC is off and that they should "click here" to turn it on. From ignorance or carelessness the user frequently clicks the window and re-enables UAC. How can I prevent this message from appearing? I want UAC off on this machine and I want it to stay off!

Iv'e been having a warning icon show up in the system tray lately, but I can't right click it, open it, or get any info whatsoever. Not a big deal really, just an oddity thats bugging me. Event viewer just shows normal error and warnings, although one DID show a reg. leak. Not sure if theres any relation there. Like I said, its not big deal...just more curious as to why I can't click or open the icon.

When my battery runs low I usually don't notice it's happening until it's too late. On my last laptop under XP I was given a screen pop-up warning to plug in my power adaptor before it was too late. I've searched all over the Power Management section in Vista and cannot find this ability even though I'm sure it's there. Where is it?

I just built this PC, installed Vista and also MS Works 2001. I keep getting a flashing UAC warning in the task bar that WKUpdate.exe wants to access my computer. I can click allow or deny, and it keeps coming back, no option to add to trusted users. I am about ready to turn UAC off anyway.

I have Vista Home Premium 32 bit. I have issues with the system cold rebooting while surfing any websites. I have a Dell Inspiron 1720 system. I've had several avenues of support from Dell's "experts" from India. None has solved the issue so far. If I run a Video card stress test, then go on a website and surf, the system will cold reboot in less than 10-20 seconds. The CPU does not seem to go over 60c, and the memory does not seem to run out of resources. Currently, if I surf for about 30 minutes or so, I will get a reboot. I have reinstalled Vista with SP1 and all updates.

I am running Vista Home Basic. I have good computer knowledge and skills although certainly not an expert. I can't understand why I am constantly getting the low C: memory warning. I store all pictures and music, etc. on a separate hard drive, and I have carefully gone over my program files and uninstalled any that didn't seem worthwhile. I have a 70 gig hard drive which seems like lots and is more than any computer I've owned before. Sometimes it seems that if I delete files, etc. to clear up memory and the next time I come back to my computer I'm out of memory again. I often get the "could not complete back up due to insufficient memory" notice. I'm unclear on what is being backed up and if this is part of the problem. I have 3 GB of RAM and the Virtual Memory is currently set at 3242 MB

When I use harmless programs (such as createinstall free), I get a warning: an unknown program wants to access your computer (litteraly translated from Dutch). How can I disable this FOR ONLY THIS PROGRAM. That means: My intention is to disable it only for createinstall, and not for any other programs.

I am using Vista Ultimate and am on a fairly new computer, does anyone know what is causing this? I've ruled out overheating and energy problems. I set windows to not automatically restart and give me a blue screen on crashing, but it still shuts down and restarts with no warning. Is this a hardware issue? It's done this since I've gotten the computer but it seems to be getting worse now.

When my PC was delivered, and evaluation copy of McAfee Command Centre was pre installed. As I prefer to use my own antivrus product as well as Windows own firewall, I uninstalled McAfee. Although it didn't fully install, I removed the files left behind with the removal tool provided by McAfee. I installed my own antivirus product, aVast, and activated Windows firewall. If I look in Security Centre, the is a conflict warning saying that I have two firewalls activated. For some reason, McAfee is still shown as being present as both a firewall and antivirus protection. I don't know how this can be because McAfee is no longer on my computer. Furthermore I cannot find any way to remove the reference to McAfee.

I was going to run SP1 Disk Clean up tool but I need clarification from this warning from BRINK:
"WARNING
Running the Windows Vista Service Pack 1 Disk Clean-up tool permanently removes the ability to uninstall the Vista SP1. Do not run this tool unless you have no plans of uninstalling the Vista SP1 and just want to save or regain hard drive space. The only option to remove the SP1 after using this tool is to do a clean install of Vista".
If for any reason I need to clean install Vista, would this be a problem? In other words, would I be able to... after having used SP1 Disk Clean up tool?

FYI The latest Windows Updates include Security Update KB941644 which is rated as Important; is in fact Critical. Windows Update provides only summary information and links; the reference security "Vulnerabilities in Windows TCP/IP Could Allow Remote Code Execution (941644)" clearly says this update is in fact a Critical update for Vista (and only Important or Moderate for other OS's). If anyone knows how to notify Microsoft of such errors directly please could they do so and/or let me know for future reference?

I truned this off a while ago and since then I bought a $350 video card and Aero still turns off when going to certain web pages and I want to find out what is still causing this after such and expensive up grade to get so little in return. So how do I turn this warning back on? The card is an 8800GTX.

My machine (an H-P Notebook Pavilion running Vista Home Premium 64 SP2 with 4 gigs of onboard RAM plus 4gigs of ReadyBoost and 4gigs of PageFile) is generally running fine but I do install a lot of sofware apps to check them out and often uninstall them if I discover they are useless to me. I used to be an engineer before I became terminnally-ill so I really like utilities. Also, I tweak it frequently closely following the instructions from you really bright guys on the respected forums. Anyway, I periodically check the event viewer logs notwithstanding that health check finds my machine to be generally healthy. I haven't experienced any boot problems other than on rare occasion it will be nearly loaded and automatically return itself to the boot screen with the H-P logo and boot up fine then.
This evening I noticed several critical events under Diagnostics-Performance Operational. I'm pasting a copy of these into this missive because I am wondering if this is anything serious. Naturally, I don't have an original installation disk for the machine thank you H-P but I do have a set of disks that H-P provided me one time when they couldn't get my machine to burn disks from the Recovery partition that came in the first machine I purchased prior to them having to replace it when it crashed during a BIOS upgrade. I also have a raw version of my operating system I purchased but can't use because it voids my warranty.
