Hard boot last night, now can't stop booting

November 9, 2011 at 16:19:52
Specs: Windows 7
Windows XP Boot Loop - last night I powered off my PC suddenly (accidental), and now it just goes into a looping boot. Can get into Safe Mode okay. Have tried:
chkdsk - no errors
disabling automatic reboot - no valuable info
unplugging all hardware / USB
Restore to prior date
Loading Diagnostic startup
Loading Selective startup (nothing checked)
altering regedit line relating to sp (changed number from 1 to 4; was a prior solution listed)

Do not have XP install disk (no surprise)
Have SP 3

Have run ouyt of options - can't figure out what to do next. My heart tells me it's something simple, but I can't find it. I beg for help. Thanks in advance.

Tell us the make and model of your brand name system, or if you have a generic desktop system, the make and model of the mboard.

The specific model of a brand name system is often shown on a label on the outside of the case somewhere, or it can often be determined by going to the brand name's web site and loading a program they have available, if Windows is still working, on the subject computer.

If it's a Dell computer...
Go here for how to find the Service tag "number":
http://support.dell.com/support/top...

Tell us what it is.

If it's a HP or Compaq computer.....
Go here:
http://partsurfer.hp.com/search.aspx
Scroll down a bit.
Look for the similar label on the outside of your computer.
Quote the specific model number - that's at the end of the first line.
Quote the Product number - that's on the third line.

If it's a Lenovo computer
Find your specific Product number and tell us what it is:

Finding my product number
http://support.lenovo.com/en_US/Fin...

The model, sometimes the make, of a mboard in a generic desktop system is usually printed on the mboard's surface in obvious larger characters, often between the slots.

...........


I'm assuming this is a desktop computer.

What do you mean when you say Hard Boot ?

Did you unplug it rather than merely accidently shut off the mboard ?

Was there a power failure event just before you had this problem ?
Lightning strikes in your area ?


"disabling automatic reboot - no valuable info"

Did you get any message on a blue screen ?

If yes tell what it said - the text that is not generic.

If you see a STOP error, quote it - we don't need the stuff in brackets to the right of that.

If a problem file is named tell us what it is.
.....

If no message on a blue screen....

It's probably a hardware problem, not a software problem.

Make sure there is nothing loose that is metal that may be shorting something on the mboard or under it..
If you tilt the case in various directions you may hear that there is something loose.

Make sure there are no metal mounting posts under the mboard that are NOT where a mounting hole is

Look for damaged wiring that allows bare wire to short to something.

Some mboards develop this problem - electrolytic capacitors were installed on them that were not properly made, and they fail eventually - the mboard manufacturer didn't know they were improperly made at the time the mboard was made.

Open up your case and examine the mboard to see if you have bad capacitors, and/or other findable signs of mboard damage .

What to look for, mboard symptoms, example pictures:
http://www.badcaps.net/pages.php?vid=5
Home page that site
- what the problem is caused by
- he says there are STILL bad capacitors on more recent mboards.
http://www.badcaps.net/

Pictures of blown capacitors, other components, power supplies, fried Athlon cpus, etc.:
http://www.halfdone.com/Personal/Jo...

There can also be defective capacitors inside the power supply that may cause your problem, or on a card in a slot.

Try a power supply from a different working computer if you can.
...........

We frequently hear of problems caused by the capacity of the power supply being inadquate for the video chipset system power supply wattage/current requirements of a card installed in a slot.

If you have a video card installed in a slot, which model is it ?

What is the max (combined or total ouput) wattage capacity rating of the power supply ?

What brand is it ?
E.g. if it's BESTEC that's a likely culprit.

Wow. That's pretty extensive. Thanks so much for your response. I hope I can live up to it with my answers.

I have an ACER Veriton M460 desktop. I hit the power button on the front of the PC box. I did not realize that programs were still running and I was in a hurry to shut down for the night. My bad. I had already turned off the monitor, so there was no chance to see a potential error message when I shut the PC off. It wasn't until later when I tried to turn the PC back on that I found myself in the boot loop.

RE: Disabling automatic reboot. The reason I said no valuable info was that I was talking with my brother on the phone (he's a computer professional) and reading him the message and it brought that response from him. I can tell you this is what it says on the blue screen:
PAGE_FAULT_IN_NONPAGED_AREA
Under technical information it says:
*** STOP: 0x00000050 (followed by numbers in brackets you said you didn't need)

Not sure if this is true or not, but it sounds like if the mboard or power supply was shot, I would not be able to function in SAFE MODE as I am. Am I correct in this assumption?

Thanks for whatever further guidance and knowledge you can provide.
-Steve

Also, to answer the other questions, there was no power outage, no thunderstorms, nothing unusual about any other circmstance other than my (stupidly) shutting off the PC while programs were still running. Somehow I think it really has to do with that action.

Usually not shutting down Windows properly that way causes no harm to the data on the hard drive, but sometimes it does.

It's extremely unlikely doing that damaged the power supply.
Unplugging the computer while it's running CAN..
It's even more unlikely it damaged the mboard or anything connected to it.

On the other hand, Acer and other brand name system makers DO use el-cheapo power supplies..

Did you use CHKDSK without any switches ?
That doesn't fix any errors found.

If you DID use CHKDSK /F, try CHKDSK /R - it tests for more problems, checks the entire partition.

If no drive letter is specified, e.g. CHKDSK /R rather than CHKDSK /R C: , it checks the partition Windows loaded from, which is usually C.
.....

Like many other STOP errors, there are lots of different things that can cause
"PAGE_FAULT_IN_NONPAGED_AREA
*** STOP: 0x00000050 (followed by numbers in brackets you said you didn't need)"

Usually the stuff in the brackets is specific only to your computer and useless regarding searching with it, although in rare cases certain things in that indicate a certain problem in a lot of cases, especially the first two items.

In most cases the STOP errors can be caused by hardware or software problems

" I was talking with my brother on the phone (he's a computer professional) and reading him the message and it brought that response from him."

Does he have experience fixing problems ?
....

"Can get into Safe Mode okay"

If it does NOT have the boot loop problem when you do that then it's NOT caused by a hardware problem - it's caused by something that is loaded when you boot normally that is not loaded in Safe mode. Safe mode doesn't load a lot of things.
CHKDSK can find no errors yet there's still something wrong.

If that works okay, try Enable low resolution mode or whatever is similar instead of Safe mode
(I haven't installed Windows 7 yet, but I do have an XP/Vista dual boot computer - Vista is the same as Windows 7 for many things).
If that works fine the problem is probably related to the specific video drivers loaded when you boot normally. That mode loads everything normally except it uses default VGA drivers like Safe mode does.

If you get the boot loop no matter what, or only when you try to boot normally,when you selected Disable automatic.... did you see a message on the blue screen regarding a mini dump having been made - it's usually near the bottom of the screen.
If a minii dump file was made, it can be analyzed, probably in Safe mode too.

Search the Web for: WhoCrashed, download it, install it.
If you must use your computer to do that, load Safe mode with networking of similar if it doesn't loop in Safe mode.
......................

Try doing the System Repair option here:

What are the system recovery options in Windows 7?
http://windows.microsoft.com/en-US/...

(Vista has the same or similar - I've only used it once).

Brand name computers often have the Recovery Options pre-installed on the system - you don't need the Windows Vista or Windows 7 DVD in that case.

They also often have the most important files from the DVD on the system so you don't need the DVD to install features that you would normally need the DVD for.

shut off the unit. Take the ram modules out and put then put 1 one back in it....try and boot, if it loops, shut it off, remove that stick and try the other one.....maybe its a faulty ram module or a poorly seated module. If you have only stick of ram, just remove it and put it back in...make sure it snaps in nice. The kicker is I would expect it to fail in safe mode as well, but you have nothing to lose. Make sure it is powered off when taking them in and out.

Thanks again Tubesandwires for your speedy and informative reply, and to opperRox for your ideas as well.

I ran chkdsk /f and /r to no avail.

My brother's job was fixing computers. (Unfotunately, he had a stroke earlier this year, so his communication skills are impacted, though he has retained most of his knowledge and abilities.)

There was a dump created but it doesn't give any file location.

Now, though, the problem has gotten worse, and I can't get into SAFE MODE anymore. It hangs on the black screen loading the drivers and always stops on kl1, which is a Kaspersky driver of some sort. I've tried several times to boot the computer and it always stops there. I left it and went to the gym for a couple hours and when I came back it had apparently finally gone to SAFE MODE, but the last time I entered SAFE MODE I checked off 'perform chkdsk on next startup' and haven't been able to access the system since to shut that off.

It's on stage 5 of 5 right now, so I'm going to sit here until it's done. I plan to pack up the machine tomorrow and bring it to my brother (I was trying to avoid the drive up to NH) and he thinks he should be able to diagnose the problem and resolve it.

If I had to guess, I think it's something to do with timing, since I can get to various screens in normal mode until it reboots. I can even get as far as the Desktop, but it always boots in the same time frame, regardless of how far into the system I've gotten.

If my brother resolves this I will let you all know what the problem was and his solution.

Before you take it to him.....

Test your hard drive with hard drive manufacturer's diagnostics.

E.g.
Seagate's SeaTools will test (almost) any brand of hard drive.
http://www.seagate.com/ww/v/index.j...

Do the long test.

The Dos bootable versions of SeaTools can test the hard drive when Windows will not load properly, or even when the drive has no data on it.

It the drive itself passes the test, any data problems on the drive can be fixed one way or another.
..............

(You could try these things without having tested the hard drive. However, I always test the hard drive first when Windows is behaving wierdly, and I recommend doing that.)

If the drive itself passes the test.....

See near the end of response 4 - try doing the System Repair.

If that isn't enough, use the same interface to try using System Restore to load a previous restore point, dated BEFORE you first had your problems, but not too far before.
...........................................................................

"My brother's job was fixing computers. (Unfotunately, he had a stroke earlier this year, so his communication skills are impacted, though he has retained most of his knowledge and abilities.)"

In that case, he can probably fix your problems, if he's familiar with Vista or Windows 7. or both.

"I plan to pack up the machine tomorrow and bring it to my brother (I was trying to avoid the drive up to NH) and he thinks he should be able to diagnose the problem and resolve it. "

Good idea, if the stuff I suggested above in this post doesn't solve your problems.


"There was a dump created but it doesn't give any file location."

It always saves it in the same location.

If Safe mode were working, if you download and install that WhoCrashed program, it will automatically find it, and previous mini dumps.

Even if you can't access Windows properly on your computer, you can copy the mini dump files and use WhoCrashed on a working computer to analyze them.

"the last time I entered SAFE MODE I checked off 'perform chkdsk on next startup' and haven't been able to access the system since to shut that off."

In XP you can't do that in Safe mode as far as I know. I don't know if that applies in Vista and Windows 7.
