Cant Boot Safe Mode


M

MSNews

I have an XP sp3 box that can boot OK in normal mode but crashes / stop
error in any form of safe mode.
It crashes at mup.sys. I tried copying a new mup.sys. Also removed
realplayer(read another article with this as a possible fix). This PC did
have a virus, we are sure it is cleaned out. Could it be leftover damage?
anyway to fix without reloading OS?

Most likely.

What Virus was that?
You may have a boot sector virus or even a batch file fooling you to believe
it is Normal mode while it is vice versa scenario?
If you have shares that can harbour the virus back and forwards, it can be
easily done, infecting the machine again and again!!

Make sure all shares and all storages are malware virus free by scanning.
Did you run the sfc /scannow to correct corrupted/damaged files?

Run a thorough scan by doing the following steps:

Click start >> Control Panel >> Double Click Network and Internet
Connections >> Double click Internet Options, on the IE Properties window
you will see these Options:
General | Security | Privacy | Content | Connections | Programs
| Advanced .

Click on General Tab (1st Tab on the left) and you will see a Button called
[ Clear History ..] click on it to clear your History caches, then click on
[Delete Files..] to delete Internet Files created over the time, click on [
Delete Cookies...] to delete your cookies left by visiting websites.

= Then try to Disable the Add-Ons on your Browser somehow installed on your
browser, On how to disable the Add-ons follow this:
Click on Programs Tab and then click the Manage Add-Ons Button there Disable
the None/Not Verified Plug-ins/Add-ons ( you need to Renable them one-by-one
later and see which is the culprit .
How to manage Add-Ons:

Then click on Advanced tab and scroll down to under the Browsing Option:
[&] Browsing
[ ] Enable Third-Party browser extensions (Req Rest) uncheck this box.
Click [OK] to close the IE properties window.

Burn a couple of these to a CD (using a working machine) and test the
infected machine with them:

Bit Defender works best for me..

Then run:

Is there an entry in the Event Viewer logs at the time you tried to
reboot into Safe Mode and it somehow "crashed"?

It probably did not hang at mup.sys. That was simply the last driver
listed before the actual driver caused a hang. Something after it
caused the "crash".

Use SysInternals LoadOrd to show the load order of drivers. What is
after mup.sys? Your video card drivers perhaps?

See what happens if you unplug all USB devices before booting into Safe
Mode. If you use a USB mouse or keyboard, hook them through an adapter
to the PS/2 ports (if you have them since many mobos in the past couple
of years are too cheap to include them).

LoadOrd is new to me and looks interesting. What is the significance of
the tag?

Alas, LoadOrd is one of their utilities that SysInternals never bothered
to provide a .hlp, .chm, or readme.txt file to explain all its values.
Clicking on the columns in the header row does not resort the list so
presumably the order shown in the list is the order the drivers are
loaded (there is a not on the product's download page that PnP devices
can load in a different order depending on when they get accessed and
why I mentioned about unplugging all USB devices).

Thanks for responding.

I had noted the comment about PNP devices.
