Computer Runs Great Until Reboot Inside W7

[BarryLumpkin]

My Gateway runs great until a restart is requested by me or a program. A few days ago, it would restart just fine.

When I select Restart, the computer appears to shut down fine, it beeps to restart, the Windows 7 screen begins to open but it freezes with three colored dots on the screen. It always stops in exactly the same place.

If I kill power, then boot again I get an offer for Windows to repair itself. If I let it, it cannot repair. If I select Boot Windows Normally, all is well. I can't tell there are any issues.

Except for this one problem, things are really running well. Odd.

I've run Chkdsk, SFC/ SCANNOW, and PC Pitstop Optimize3. Nothing finds a problem or fixes anything.

I'm stumped. Any ideas?

You might try a "system restore" to a checkpoint created back when you know the system would reboot.

Can u run the Memtest or Windows memory diagnostics?

Has this been an ongoing issue? If so, a bios update may fix it.

 

[BarryLumpkin]

Thanks for all the good ideas...

Memtest ran 8 passes without issue.

System Restore is not usable because it was cleared recently after the removal of a trojan.

The motherboard has the latest BIOS.

Thanks, nikorr... but I'm not having the same problem. Mine post just fine.

Can you boot into safe mode? It would be nice if you can turn boot logging on.

 

[BarryLumpkin]

Hawkeye22,

I've turned on boot logging in safe mode. When I do a search for ntbtlog.txt, nothing is found. What am I doing wrong?

 

[Hawkeye22]

ntbtlog.txt should be in %SYSTEMROOT% which should be c:\windows. However, see this link.

[BarryLumpkin]

Now I know why it's not being written... just as W7 start to load it hangs. I don't think ntbtlog is going to be able to help.

 

[Hawkeye22]

If you can boot into safe mode it must be a driver or startup program hanging you up. Have you tried booting into safe mode, run msconfig and disabling your startup programs temporarily. You might find it via trial and error by running a single startup program at a time or in small groups.

 

[BarryLumpkin]

I can boot into safe mode without a problem. The computer will not do a restart even from there.

I'm beginning to suspect a hardware issue. Maybe the PSU.

 

[Hawkeye22]

It can boot into safe mode because most of the drivers aren't loaded and startup programs are supressed. Did you run msconfig and disable all startup programs while you were booted into safe mode and before rebooting?

Other than that, I don't know what else you can try.

Problem solved! I replaced my PSU with a Cooler Master 1000W Silent Pro. It restarts flawlessly now.

Why would a computer run just fine until I ask it to restart? How can this be related to a bad PSU? It seems strange to me.

Why? Mysterious world of electronics : ) Glad u got it solved!

 

[BarryLumpkin]

nikorr,

Well... I spoke too soon. I've even wiped the disks and reinstalled. Still the same problem.

My guess... there's a driver hanging just as Windows 7 boots. I always get the three dots, then the freeze.

Everything else seems to be running perfectly.

 

[Twoboxer]

Try enabling Boot Logging on a restart . . . before Windows begins to boot, press and hold the F8 key . . . then boot by clicking "Enable Boot Logging".

Windows will create a file: C:\Windows\ntbtlog.txt

Hopefully the last thing listed will be the prog that your system is hanging on. Or the one before it. If the latter, you could enable Boot Logging during a boot you know will be successful, and get the full list.

never used it - but in order for the feature to be useful it should work, and may give us some more info.

 

[BarryLumpkin]

Twoboxer,

Here's the last line...

Did not load driver \SystemRoot\System32\DRIVERS\srv.sys

What do I need to do next?

 

[Twoboxer]

I have no clue lol. But here's what I'd do:

Get a log of a full boot. Find the program that loads after srv.sys

Start a new thread asking entitled something like "Win7 Boot hangs after loading srv.sys" and in the text mention the name of the programs that load before sry.sys, and after it.

Then ask what do I do next.

When a thread gets this long, people don't often check in. Folks who may know something about where to go next are more likely to respond to a new thread.

 

[BarryLumpkin]

Twoboxer,

Thanks for the suggestion!

 

[BarryLumpkin]

Problem solved! Bad motherboard. All is well.
