Computer Slow After Sudden Reboot

Sep 3, 2007

I was playing world of warcraft while watching a video and chatting on msn. My character died, and then suddenly BOOM, my computer restarted for no reasons (I ever saw my light turning down in my room) Now, its all screwed up. It takes AGES just to open winamp, most of my applications just won't open or take too long.

SP3 Sudden Shut-down - Asking For Activation After Reboot

Oct 4, 2010

So I reinstalled XP Home on an MPC Pentium 4 HT. After installing all the windows updates, including SP3, and some basic programs, I was up and running. The pc was running fast, and it was a joy to use. Then, just 1 week after the initial install, I'm on the computer playing a flash game, when it suddenly shuts down. I reboot, and instead of going to Welcome screen, then desktop with all my icons, it's showing the factory default resolution (you know, huge mouse cursor and all), and asking me to activate Windows, which I did about 6 days ago

Sudden Very Slow Performance

Jun 4, 2006

I'm on WinXP. I have a 2.4GHz PC. It used to take just 40 seconds to boot up my computer. Now it takes at least 7 minutes and then if I try and open Outlook, another 5 minutes. It was working fine a week ago, and oddly enough, this sluggish performance seems to be at the same time I installed a bunch of Windows updates.

I try and run Norton to check for viruses, or burn a DVD, everything works okay until about 5 minutes into it, and then suddenly I can no longer move the mouse and everything seems to be hung up. I can't even do a ctrl-alt-delete.

I'm not sure how to proceed.If need be, I am willing to back up all my files and initialize the hard drive and start with a clean slate, but I'd prefer not to.

1) Should I re-install Windows? It says the version on my CD is older than what's on my computer, and I think it said I should back up my files.

2) Should I run hi-jack this? Never run that before but maybe someone can see something that doesn't look right.

3) Is there a good free utility out there that can help diagnose the performance issue?

4) I know I have too many processes running in the background at any given time, and I'm not entirely sure which ones are necessary. Maybe some process in the background is slowing everything down?

I haven't been able to run Norton or anti-spyware, because the computer just stalls several minutes into the scan. I'm just thinking now, maybe I should run in Safe Mode to see if I can run Norton or Ad Aware?

Sudden Slow Down On Notebook

Sep 27, 2010

The problem I got is that suddenly my trusty notebook started taking 10 minutes to start up while it usually took it 30-50 seconds, I really hope this is not a hardware/RAM issue as I don't have the money right now to buy required parts to fix it and my job depends on working in my computer. And in case it's useful here is a logfile of hijack this I just did.after the 10 minutes it takes it to start, it works as smoothly as it have always done,

Computer Takes 3+ Minutes To Reboot / Slow Internet Speed?

Nov 25, 2004

XP Home reboots in the 3+ minute range. Once it gets to the 'Starting Windows XP' screen, it loads fine. Some damnthing is hanging.MY comp is running slow. Expeciially on the net. Task manager is reporting no excess network use. IE 6 acts like it's on a 56k modem. I use Mozilla FireFox, which runs fine, but my wife is a IE 6 fanatic. Shareaza and WinMX load slowly and take a minute or more to change tabs. BitTornado (latest versions all) loads and runs fine, but seems to hang after an hour or so. It stops updating speeds, seeds, peers, etc. It also closes slowly. Once I get online, the comp slams on the brakes. Mozilla is the only app that seems unaffected. Sygate is also logging a lot of portscans. 7 in the in the last hour or so. All from the same IP address.

Computer Running Slow - Not Just Internet Slow But Onboard Slow

May 10, 2010

Lately my computer has been extremely slow, not just internet slow but onboard slow. For example, if I click on an application from the desktop it will sit there for 10-20 seconds before anything happens. Occasionally I'll click multiple times on something and nothing will happen then 30 seconds later it will open multiple instances of things. This delay has been happening with just about anything I click on, acting like the computer's busy doing something else when nothing else should be going on. I've looked in the task manager and the applications column will be blank

How Often Should Reboot Computer

Mar 6, 2007

How often should you reboot your computer? I've noticed that my memory usage gradually climbs the longer I have my computer on. I generally put it on standby every night before I go to sleep? Is this a good idea? Or should I just get in the habit of shutting it down at night?

Sudden Ntdll.dll Error

Jun 25, 2005

I am not sure I am in the correct forum, but I recently started having a problem with an application starting to load and then a message coming up stating that there was a problem with the "ntdll.dll" file.

I even located a copy to download, placed that in the WindowsSystem32 folder and each time I continue to attempt to launch this application, it partially starts up, then hangs and then gives me the error message.

Is there something I am not doing correctly? Any suggestions? It had been working just fine for the past year or so and about a month ago, BOOM, this error message came up.

Sudden Rash Of Hangups

Apr 15, 2006

Problem just started a day ago but it's really got me down. I'm freezing/hanging up in any graphic intensive program from Photoshop to games. PC will either freeze up needing a reset, or hang up then crash and restart Anyway, I've been through all the preliminary steps, did viral scan, spyware scan (CA AntiVirus and Ewido), cleaned the disks, defragged, etc. I updated my card drivers, made sure I'm up to date on all drivers actually. Still same problem. I tried even removing my antivirus program just to see if that was the problem (I just renewed it several days ago) but to no avail.The event viewer gives me no clues about what's going on. Hopefully someone can help me out, just started all of a sudden! Here's some system specs:

Sp3, Slow Domain Login Not DNS Issue, Not Slow At Applying Computer Settings ?

Dec 23, 2008

This is a Windows XP sp3 domain connected PC with one specific user, which all of a sudden takes 2.5mins to log in to the domain, Where it used to take just about 20 seconds. Other users on the same PC is all OK 20sec login This is not the usual where it hangs at "applying computer settings" or "personal settings" it's after those two has passed that it just hangs for a couple of minutes.
All i get is the mouse pointer (not even hourglass) and the desktop wallpaper for about 2-3 minutes. When it finally logs in everything is as quick as you would expect that spec of PC to be (1,6ghz Sempron, 1gb RAM, 40gb IDE-100 HDD)

What Can Cause Computer To Reboot While Burning

Jul 13, 2005

I have observed this since i had my PC, while burning a CD, my computer would suddenly restart as is the reset button had been pushed,sometimes even while reading a CD (even tho i havent observed this in a while) and even sometimes as soon as i was in the BIOS (that was quite unconvenient for trying to reinstall Windows I admitt) The problem is that, since that problem appeared (that's indeed since i've had this homemade PC), i changed the CPU, the motherboard,the burner, the alimentation, the RAM, the graphical card, the modem, i mean, everything besides the floppy disk reader thing, i also installed another Windows XP (SP1 indeed, even tho it was badly burnt so whenever i install it there is dll's that won't be installed) and in spite of all these changes, i still get those reboots while burning, and that's quite annoying mostly that it kills your CD's. so what can it be due to? i'd really appreciate an answer from anyone who might have one, cuz i've had this problem for 2 years now and now that i'm getting out of room on my hard disk and need to back up lots of things on CD's.

Sudden Freezing, And Apparent CPU Overload

Sep 26, 2006

My comnputer just started freezing randomly, and I cannot listen to music and do something else anymore. Any action that MS Word, or Firefox, or IE, etc, takes, and the music starts skipping. Same thing with videos. The computer has just become very uncooperative in general. And the "activity light" of the computer that normally blinks, sometimes stays on, without blinking, for minutes at a time, and I am not doing anything.

Sudden Case Of Missing NTLDR

Apr 2, 2006

Everything was fine last night when i was on my computer but when i woke up this morning and booted her up i recieved the "NTLDR is missing" error message with instructions to use control+alt+delete to restart and try again. I have not recently installed any new hardware or changed configurations and the only new software is Diablo2 and its expansion which has been on my computer for a week now (its run fine in the past and never caused any problems). I've been reading through the forums for most of the day and tried several different suggestions to fix my problem but to no avail. I've tried using a boot disk i made off of a friend's computer, rebuilding the boot record using the recovery console, and i even tried that NTLDR "fixer" disk that i downloaded from a link i frequently see posted. Nothing has worked. The only interesting thing is that when i use that fixer program (the one that gives you 10 boot options and you have to go through every one to find one that works) is that instead of getting a missing NTLDR message, i get a hal.dll error instead! So i go back into my XP cd and expand the hal.dll into the system32 folder on my drive and try again but now i'm back to the NTLDR error!

I really dont know what to do here and any help is appreciated! Also, i'm not tp sure how vital this is but my drive is labeled D: although it is the only HDD in my computer, when i try to use the recovery console i only have one option for an OS to explore and it is labeled C:. I'm not sure if how this happened is important to my current situation but i can explain it if necessary. Again, any suggestions here would be a big help and hope to hear from you soon. Oh, formating is also out of the quesion as i have no backups of my current papers, projects, and other data.
