Boot Problem

I am running Win 7 64bit Ultimate

Starting 2 days ago my PC won't boot properly. It reads the BIOS,
then I get the colourful windows loading logo, and then when I would
get the logon screen, I just get a black screen, with my (wireless)
mouse pointer, but no (wireless) keyboard access. All I can do is to
power down.

Booting into safe mode is fine. If I then run System restore, and
after a long time I get the message that SR has failed because of my
antivirus, which isn't loaded in safe mode.The message also says that
no files were changed by SR.

However after every failed SR the PC boots normally, but at the very
next reboot it fails again! Bizarre.

I have also found that if I go into safe boot, and uninstall *any*
programme, the PC will boot normally, but subsequent reboots fail.
This is again bizarre.

The event log shows numerous errors, such as "The following boot-start
or system-start driver(s) failed to load:
discache
MpFilter
SaibVdAd64
spldr
vpcvmm
Wanarpv6"

However on each failure the errors vary a lot.

After a failure to boot, several reboot tries later the PC *may*
occasionally boot.

Before the problem developed I had not installed any new devices,
drivers or apps, but maybe some auto updates could have happened.

I have extensively checked for viruses, malware, etc.

Regards
Doug

What antivirus are you running? I have seen issues like that when the AV
(especially Internet Security Packages) damage the Winsock entries and
create problems with booting, Try the following from an administrator
command prompt

netsh int ip reset

Which will reset your TCP/IP stack and clean out any problems

another to try is

netsh winsock reset

or

netsh winsock reset proxy.


You need to restart after them to get things going again.

Looks similar to the problem detailed by Prevx.

You could try their shell fix.exe. Won't do any harm.

I had similar/same problem a few weeks ago. Got me pulling out whats left of
my hair.
The damn thing would boot up to the "Welcome" screen then go blank, and stop
there.
Worked OK in safe mode. (Window$ XP).

I reloaded Window$, I downloaded anti this that and whatever else via
another machine and tried you name it - still nothing!
Eventually by shear chance, I found the fault - the monitor plug on the back
of the PC was not engaged fully. It had somehow become partially disslodged.
Inserting it properly cured the problem - two days of frustration!!

Hi XR8 and Acacia

I may have fixed it. Fingers crossed.

When the PC didn't finish its boot, it collected a bucket of errors in
the Event Viewer, and these changed considerably with each failure.

After hours of going through the Event logs, one process always came
up each time there was a boot failure. It was Microsoft Security
Essentials.

I uninstalled, cleaned the registry files again. And the PC booted.
Now it has occasionally booted OK before, so I am still not sure I
have a fix. I reinstalled Microsoft Security Essentials. It's been
two days with many reboots (just to test) and the PC has booted
normally every time.

Fingers crossed.

Many thanks for the feedback!
Regards
Doug

What you did was easy with XP as it allows for a repair install. No
such thing with W7 or Vista for that matter. W7 has a complicated work
around for any problem.

Even though I do like using W7 its not open like XP.

I have not mentioned the monitor in my reply, should I have snipped the
irrelevant parts then.

I was comparing operating systems

Not referring to a hardware problem but the fact in the first line "I
reloaded Window$," the OP did reload the XP OS in a search to eliminate
the problem this is possible with XP. This is not the case with a
repair of W7.

And what's more I still can't understand why the monitor cable being
dislodged would have created a situation for the OS to be reinstalled.

Does that make it any clearer???????????????? or what?????????????

Making a small alteration found on google allows upgrades and hence
repairs in win7 making it's maintenance very xp in many respects

Not in my case where the MB had to be changed. Is this included in the
secret Google site?
