Problems have been.#1.would only start in safe mode.#2.if try to start normal hangs up on logo screen.#3.tried to do chkdsk and restarted...after restart wouldnt even go in safe mode(hung up at system32/drivers/agp4440.sys)(also some other files were missing at other times).#4.Could not not access cd rom to burn files(tried to backup drivers and could only send to floppy,which worked ).#5. I erased 1 harddrive with system suite6 professional(only one because windows told me the 2nd one was not formatted)and now i am trying to install windows xp and at first had a hang up at setup on an ntfs file,retried and got "corrupted file sym_hi.sys message".found out online it could be do to bios settings or actual physical sdram memory problems,so i fiddled with bios setttings and got windows to install and restart now it has taken about an hour and a half to finish and finalize.my question is...does anyone know what all this means??is it an old piece of crap?,do the bios settings need changed?

My Laptop (running XP) will boot up to the login screen (which now takes about 5 minutes when it used to be less than 1 minute). Once I enter my login information and hit enter it stalls for about 5 minutes and then returns to the "ctrl-alt-del login screen".I have 2 "profiles" and can successfully log in to one under the administrator login but I don't get a start button and the windows look "different". For example, the expand/minimize/close buttons when I run the task manager look more like how I remember windows screens looking years ago if that makes any sense.

On boot sequence, PC hangs on Windows boot screen - with the good old progress bar churning along for eternity. It just stays there. It is possible to boot into safe mode, safe mode with networking, etc. but never boots up normally. 'Last Known Good..." does not help at all.
I have tried 'repairing' XP using the recovery console (deleting the boot.ini file, then BOOTCFG /REBUILD and then FIXBOOT) to no avail. Do not know where in the boot process it is getting hung up and not totally sure how to determine that.Using Windows XP Media Center Edition with SP2. Plenty of RAM and disk space.
Had this problem once in the past and it seemed to self correct after about 50 reboots.
Does this sound like a re-install of XP is required or are there any other options that might work?

i have ONE hard drive with partitions. I had a really bad setup first, I had 1 partition with 3 windows installs on it, folders like WINDOWS, WINPRO, WINN, I never took the time to delete them or whatever, and I was using winpro as my main OS. When I was running the above setup, when I boot up it would ask me: Select what OS to load Windows Pro, Windows Home, Windows Home
I decieded to install Windows 7 Ultimate 64 bit, worked flawlessy, but I wanted to go back to windows xp pro 64 bit. So I made a new partition and installed windows XP pro 64 bit onto it. when I tried installing windows xp with my CD, the first part would work fine, but then when it restarted to continue the setup, it would load my MOBO logo and then after, it would just show a blinking underscore "_" on the top left corner, and nothing else.
I managed to install a fresh windows xp from my USB flash drive, but when booting up normally it still does not let me select what OS to log on to, it just shows the blinking underscore in the top left after the MOBO logo passes, I actually have to boot by USB drive to boot this fresh install of windows. I think something is wrong with my boot loader, but have no idea how to fix it.

I have an intermittent problem, xp hangs occassionaly at the boot screen. If I unplug the system when not in use it doesn't happen as often. WEIRD. When it does happen I have to leave the system unplugged for about 5 minutes or it won't boot. This has been happening ever since I upgraded to home XP from ME. It is a legal XP CD. I have a new amd athelon 1.2 motherboard and XP drivers for my hardware.I even reinstalled XP but the problem persists.

This makes about the 6th time I have done the install. When it boots, it hangs for between 10 and 30 minutes at the XP splash screen. The blue bar just goes back and forth but nothing happens like forever. I had tried to replace my HDD as well with an WD SATA 320G HDD, but the bios won't detect it. I tried installing a 40G HDD that had 27G of free space on it. I had been using it as a secondary until my primary went TU last week. I kept running into the problem of it hanging on installation. It would get to the point where it was installing drivers and just stop.
Due to problems that I have been having I went out and bought a new motherboard. I am now running a 1.8G Pentium 4 on an Asis 848P motherboard with 512M DDR Ram. I removed both the 40G HDD and the SATA drive from the system. They are no longer attached. I took a 13G HDD that I had removed to put in a bigger HDD and decided to use it.I did a clean install on the 13G HDD. I formatted it during the installation. Because of the other problems, the only devices that I have connected is the video card, an ATI Raedon 7500, the HDD, keyboard and mouse.The blasted thing still hangs on booting! Because I wanted to know if it happened I activated boot logging and this is what I got.

My OS is Win2K Pro and when attempting to boot yesterday my computer hung on the Go Back app and would go no further. During several subsequent attempts I got far enough in the boot process to get an error saying my keyboard wouldn't work. Using a third keyboard I somehow got a full boot with my Windows CD and quickly ran a virus scan showing no infection and thought everything was okay, took out the CD and changed the boot sequence back.Now I'm stuck on the Go Back screen again. While in BIOS I discovered it said the year was 2002 and thought that was why Go Back hung but reset the clock and still nothing works. I can't boot to safe mode (only beeps when I tap the keyboard), now the windows CD will not boot the machine. I've tried to do a reinstall, but am told two small partitions are too small (no option for changing their size) and for some reason can't install on the primary partition, just a note saying I can't, nothing else. I can only get to Set-Up and BIOS. I've tried burning different boot disks to CD (no floppy drive)on another computer but only get Retry Boot when using them.Various times I can get far enough to get Go Back to load then try to revert, but just get a Wait notice from the app and nothing further.No sounds when booting unless I tap F5 or F8, sometimes F12 beeps every time I tap. Of course I haven't backed up my documents and WAB, etc. so I'm trying not to delete partitions and start over.

My C: drive crashed and I used that excuse to buy a WD3200 320G SATA drive. My old MB wouldn't support the SATA so I bought a ECS 848P-A and a 512M DDR memory.I tried a new install of XP (Home) onto a 40G drive as primary which had 27G free space. It would only install to the point where the screen was saying installing devices and there was 33 min left on the install. At that point it would stop. The little bar on the lower right would freeze. I left it like this for over 30 min to see if it would clear, it never did. I figured that there might be a problem with stuff on the drive so I removed it and installed a 13G that I had laying around. I formatted it during the install so it should have been clean. It would install and ran until I installed the motherboard and video card drivers. When it went to reboot it would quit. It would go to the XP splash screen and stop. The blue bar would keep cycling but it would never proceed.

When trying to boot my computer it freezes.I have tried to boot into safe mode with no joy and then safe mode with command prompt.The last entry with command prompt is:multi(0)disk(0)rdisk(0)partition(1)WINDOWSSystem32DriversBTHidMgr.sysNow using the little I know about computers I am guessing that it is hanging whilst loading the driver BTHidMgr, what ever that may be and at a guess I either need to delete that driver or repair / replace it.... but.... thats about as far as I can guess.

booting my cpu because it hangs at the loading screen. I have read a lot of posts but none of them help because I can't get the cpu in safe mode. I have tried all the options and all kinds of boot disks.It won't let me use my keyboard to highlight any of the options where it says windows had problems loading and gives several options like safe mode or last good config. The keyboard will let me into the bios but after that it won't work. f8 won't take me to safe mode and it won't boot to the cd either. I had this problem once a few weeks back but I created a boot disk and after I booted from that for several times it started booting on it's own. I got the boot disk from a web site but it wasn't an xp boot disk.(i think it was an 98se or me disk) Well of course now either I have lost the disk or it just won't work anymore. I need to find a way to at least boot it long enough to get the data off. the file system is ntfs and I am using windows xp pro.

I just bought a Seagate ST3400620NS SATA HDD. I want to install it as a second HDD just for storage. I currently have a ST380815AS with the OS (XP SP3) on it as the primary drive. The PC (HP DC570 SFF) boots fine with only the primary drive installed. When I add the 2nd HDD the the system recognizes that I have added a 2nd HDD. It asks me to save the settings by pressing F1. I do that. The XP boot screens displays. The blue progress bar moves once and the system reboots. I switched SATA connectors for the 2nd HDD but when I boot I get a message that I need to move the connector back to the original spot.Then I thought maybe the MOBO (Hewlett-Packard 0A64h ) only supported 1.5 gb/s. Not the case. So I am totally stumped. I checked HPs website to see if there were any updates, and there was an advisory that a different model Seagate HDD might cause a similar sounding problem but no mention of the model HDD that I own.

I am using windows xp and just moments ago I get a problem. windows will not boot at all. Nothing unusual at start up but no windows icons/usual windows start up appear and computer sits there fans running. If I try to start in safe mode the computer hangs at system32/config/system along with the usual prerequisites and does nothing after that.Circumstances right before this started.I plugged in an old IDE harddrive(making 2 harddrives plugged in) in order to retrieve some old data. Everything starts up fine but windows freezes 30 sec into startup and the mouse moves but nothing happens(much like my previous registry problems).Restarting leads to the problem stated above.

I get up this morning and turn it on, it seems to boot okay, but after the Windows XP logo and the little blue loading bar it hangs at a black screen until after about five straight minutes I get fed up and power down. I tried booting in safe mode and that worked fine a minute ago, but now I am trying safe mode again and it hangs at a file called Mup.sys and will not proceed with the boot.

I have been suffering through a weird phenomenon lately. Whenever I go to IE the first time of any boot or reboot, it "hangs" after filling up the status bar for several minutes, then releases and all is well. (NOTE: I don't think this is IE-specific. It has happened booting apps, but I notice it most with IE as I use it extensively.) When things seem to lock up, EVERYTHING is locked up. I can't even bring up Task Manager, none of the icons in the Task Bar are active, etc. Sometimes I can Tab through other apps that are open, sometimes not, but when I can, the app is "frozen" until whatever is going on finishes. During this time, I can watch the process light (I have a Dell D600 laptop) going nuts. Before and after this event, I have run the system through the latest updates of utilities such as Ad-Aware Plus, Ad-Watch, PestPatrol, Symantec Antivirus, Ace Utilities, RegSeeker, etc., and none of them sends up a flag that anything is wrong.
My machine is always up-to-date via Windows Update feature, so I don't know what is causing this. I had the bright idea to reinstall XP SP2, but can't. Every time I try, it quits, giving me nothing more than a smal window with a red X in it and the notification that the install has been cancelled. I ordered the free XPSP2 CD just to see if that would make any difference, but I get the same error. I suspect I could attempt a slipstream install, but I don't want to go through all that if anyone out there recognizes this problem and knows what the solution is outside of doing a slipstream reinstall of SP2. Finally, I have several times done System Restores going back as far as I can, but while they have been successful (although I usually have to do the restore in Safe Mode as they will often fail otherwise), it has made no difference related to this problem.

I have successfully cloned my primary c partition of a dual boot system with XP Pro on the 1st primary partition c: and XP Pro on the 2nd primary partition as d: I can boot into my XP on the c: drive with no problem, but when I attempt to boot into my XP on the D drive it hangs on the blue screen right before booting into the user profiles. And believe it or not it continuously loops making the windows startup sound and the shutdown sound. It does the same in safe mode.
I will try to explain the process on what I did so it can help you experts figure out this dilemma that I'm having.My old drive an IDE 100GB IBM primary drive was partitioned into 3 parts: c: 30GB FAT32 primary d: 30GB FAT32 " e: 30gb FAT32 "

My computer shutdown and on boot up it hangs at the black screen showing the white bar at the bottom. I have Windows 98 and 2000 on my computer and neither will boot up from C:, CDROM, or StartUp/BootUp disks. When I try to boot up from the Windows 2000 boot up disk it sometimes will not get passed the blue screen showing 'Windows 2000 setup. Once or twice it has shown some functions in the bar at the bottom of the page. I have tried to boot up using Windows 98 start up disk but most times it hangs at C:. Last night it did open Windows 98 but would not let me reinstall 2000 or do a repair. It now is hanging in both OS. I am told it could be my memory...but how do I check? Upon start up my memory check shows all is okay. I have ran the utility disk for my hard drive and it says all is okay. Before I invest in new memory is there anything else I should check or try? My computer is older and the memory is quite expensive.

I have a computer that I recently installed a new mother board into. Everything was going fine after the installation for like a week until I decided to reformat. While reformatting I made it through the initial part of the setup where it reboots the computer. To start the second half of the installation but upon rebooting The computer hangs on the Windows XP page. Now every time I try to restart the computer it hangs in the same spot. I have done some reading around the internet and I think that the problem lies in my Bios but everything seems fine. I have tried to update the bios but the computer doesn't have a floppy drive so I was unable to. I have tried the windows recovery console where I did a fixboot and and a fixmbr

I have a problem when shutting down the computer. About 4 out of 5 times when I select shutdown, the computer hangs on the blue screen and I must force it to shut down by holding the startup button. Then on the next startup, about half the time, the system goes through a check.I am using XP2. I was told by Circuit City that this could be caused by spyware. I brought it to them for a fix, among other problem I have Spy Sweeper installed but even after a scan, the problem persists. Then recommended a clean install of XP2 but I am trying to avoid that route. One thing I do notice is that I have a constant correction on the startup scan with many files in a Temp folder of Spy Sweeper that are invalid. The system corrects itself, but then it happens again. Just to note, this shutdown problem was occurring before Spy Sweeper was installed.

I have a laptop that cannot find boot media device since it went into hibernate. I ran recovery console from Win 2000 disk and ran chkdsk but still no joy. Now I can't get into recovery console as it hangs up when it trys to log onto the WIN NT folder. If I boot as normal it just stays at the initial Windows logo screen.I can't get into dos as it wont log me into WIN NT when I select option 1 from recovery console. Also I cannot reinstall windows either as it hangs up when it says "searching for a previously installed versions of window".I heard that there is a program called Bart_PE and have downloaded it but it doesn't seem to recognize it as a bootable cd.

Before any of this happened, I installed Norton Ghost, and switched my DVD drive with a CD burner. I had to restart the computer for some reason, when I logged into XP, all the desktop icons showed and everything, then the computer just froze So i pressed the "reset" switch on my computer. Then my computer started to run the "Chkdsk" on my hard drive. It found alot of errors and dealt with them successfully. Now every time I restart, my computer hangs at the following file (the splash screen doesn't even show!)C:WINDOWSSYSTEM32DriversPCI.sys

When attempting to browse folders using Explorer opened from Start Menu Or left click on start button, Explorer will allow click on "-" to close paths, but hangs with hour glass if any attempt is made to expand any path or open any file. Explorer remains in this state until closed, at which time Windows asks if I wish to report the problem to Microsoft.If I use the"My Computer" icon on the desktop to browse, all actions including access to networked resources work perfectly.explain the difference between the two file browsing utilities and offer an explanation of the above.

Today, I found out that my computer hangs at the login screen. I boot up the computer as normal, and the login box is shown. I click into the password field (Note: I do not have the normal welcome screen, I have the Win2000 one.) and am ready to type my password. When I begin typing my password, nothing pops up. I attempt to move the mouse, but it is frozen where it last was. Sometimes it doesn't even move (The mouse) when I first boot it up. So seeing this as any problem, I go in Safe Mode. It's a sure bet that the mouse will move. Though it moves flawlessly, the password box is where the annoyance stays. I attempt to type my password, but then my computer hangs, AGAIN.I'm typing this from my brother's computer, and have yet to find the answer. I hear that this is some sort of password corruption and can be prevented by not having passwords on the account. I want to change this, but I can't login in the first place.
This I'm sure is not a virus. I scan for viruses every week (With Kaspersky), leave Ad-Aware, Giant Antispyware, and Zone Alarm on. I've used Google to search for answers, and yes I've found them being solved. They include the same problems, but they can get into Safe Mode, which in my case, I can't. I've tried Safe Mode 7 times and it doesn't work. (I can get in safe mode but the keyboard/mouse still hang)I didn't have time to backup files, and I have pictures that I haven't backed up onto CDs. People that have solved this problem have done it without reformatting, and I need a solution without reformatting.

Really don't know where to post this, so forgive any inappropriate posting.I'm running Windows XP Home, SP2 all updates current.My problem is that my computer has just been freezing up and the screen going black for no reason I can figure. I've checked "sleep" and "hibernate" settings, and they all seem to be off. I've instructed the computer to NEVER go to sleep.At first, I had the problem which I thought may have been linked to my newly-purchased & registered version of AVG AntiVirus, but then I took everything out of System Start-up EXCEPT for that, changed the time for daily update and it seemed to fix things. Then the other day, I installed Kodak's Easy Share software for my new digital camera, and the problem started again. Suspecting the software,
I uninstalled that just this morning, and restarted the computer after the uninstall. After that, my mouse would no long choose just a single selection of anything no matter how much I clicked, it would choose multiple selections. So, I rebooted.Seems fine now BUT I am leary, and of course, I have to reinstall the camera software in order to be able to transfer the pictures.
