Windows XP reboots after logon


Recommended Posts

My computers win xp pro reboots after i enter my password on logon screen and press enter everytime. I m not able to boot even in safe mode, same thing happens. The only thing thats working is safemode with networking prompt. i saw the event viewer there and its has an entry of 'DCOM error'. also when i try to open explorer.exe in cmd prompt the computer reboots again.

Any suggestions what to do now ?

Boot to safe mode

Regedit

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

If there is a key named "OldUserinit", delete the "Userinit" key and rename the "OldUserinit" key to "Userinit".

The "Userinit" key should now be c:\WINDOWS_PATH\system32\userinit.exe

If you can't get in via the safe mode

Boot to the Recovery Console

Get userinit.exe from another computer. (c:\windows\system32 folder)

Copy it to c:/windows/system32

Rename userinit.exe to wsaupdater.exe

Boot to Safe mode w/Networking. Go to System Properties - Advanced - Startup & Recovery Settings and Uncheck "Automatically Restart". Reboot. If you get a blue screen error, post the contents of that error here.

sorry but the only mode i m able to get in is safe mode with command prompt , how do i go to system properties from cmd prompt ?

Sorry, my error. I misread your post. You might want to try a repair install (boot to the XP CD and choose the second repair option, allowing XP to install on top of itself).

I did that do , nothing seemed to work so reinstalled xp on a new partition.

All problems were due to some malware i suppose. I ran AVG scan and it caught about 15 viruses and cleaned them. After that i was able to boot once and after that xp hanged on "windows is starting " itself in all modes. When i used your 2nd recovery option the setup didnot continue after "setup is installing windows 39 mins left". it never completed and thus last option - REINSTALL WINDOWS.

Really bad on part of MS, malwares can ruin a fine running system. Thinking of upgrading to a MAC ..

Hi- I had this problem (3 years later!) and tried the "MazX_Napalm" fix. It didn't work, system still reboots after login. What exactly is the fix supposed to do?

    • Are they on crack at M$? Surely living on an alternative reality? A good dump of mine would run faster down the toilet if I did not flush it. But still looks better than this pile of slop. By the way, did they also comment on what's the next "functionality added"? Maybe you can improve it if you add even more stuff to this vomitware.
    • I don't find them "bitchy" or "whiny". I think the term you should use it, uhm, "passionate."
    • Ahh, I didn't know that. It makes sense. I was thinking I would be fine with 50 hours, but 100 is close enough that I wouldn't feel like I am paying for more than I am using. I might check it out sometime.
    • Google's next-gen Tensor AI chips might be produced by Samsung, report says by Hamid Ganji Image via Google Google’s Tensor Processing Unit (TPU) is produced in collaboration with companies such as Broadcom and TSMC, but a recent report suggests that the search giant is in talks with Samsung to hand over part of the production to the Korean tech company. According to a report by The Information, citing people familiar with the matter, Google has begun talks with Samsung about using its chip manufacturing capacity for the next generation of Tensor AI chips. Google’s upcoming TPUs are reportedly codenamed “Icefish” and will be produced using Samsung's 2-nanometer process technology. Meanwhile, Samsung is expected to produce only a portion of the next-generation Tensor chips, with most of the production remaining at TSMC. The Information says the new Tensor chips are currently in the design stage and are scheduled to enter mass production in 2028. TSMC is generally considered one of the most reliable chip manufacturing partners and is trusted by tech giants such as Apple and Google. However, the growing demand for TSMC’s AI chips, combined with the company’s focus on meeting demand from AI data centers, has reportedly prompted Google to seek additional manufacturing partners for its next-generation TPUs. Besides Samsung and TSMC, Intel could also be assigned part of the production. The Information reported this week is that Google has begun talks with Intel to produce up to three million TPUs in 2028. However, this is not the first time Google has partnered with Samsung on chip production, as Samsung has previously manufactured Tensor chips for Pixel smartphones. Google’s Tensor Processing Unit is used in cloud data centers and competes with NVIDIA’s chips, which currently dominate the market. By relying on in-house chips, Google can not only reduce its dependence on third-party providers but also create new revenue opportunities. The company has already supplied its TPUs to the AI firm Anthropic.
