Stop 7F and instable system

[eljainc]

Hello,

My wife has a HP Pavilion ZT3349CL notebook PC, which runs WinXP Home
SP3. She has recently been getting STOP 7F errors on her system. We
did a MEMTEST+ analysis on the system and did not find any errors. We
then thought it might have to do with the wireless network. We booted
to safe mode and never received any errors, but as soon as normal boot
was brought into the mix or safe mode with networking, the STOP 7F
errors appeared. Sometimes the machine when booted will freeze up at
the Welcome screen. There is Trend Micro AV running on the system, so
I'm not sure if a virus is suspect here. The STOP error is 7F and
has the parameters (0,0,0,0) indicating a divide by zero error.

What are some other things to check?


Thanks
MIke

0x0000007F: UNEXPECTED_KERNEL_MODE_TRAP
One of three types of problems occurred in kernel-mode: (1) Hardware failures. (2)
Software problems. (3) A bound trap (i.e., a condition that the kernel is not
allowed to have or intercept). Hardware failures are the most common cause (many
dozen KB articles exist for this error referencing specific hardware failures) and,
of these, memory hardware failures are the most common.

Can you please an exact copy of the Stop Error report.

Disable automatic restart on system failure. This should help by
allowing time to write down the STOP code properly. Right click on
the My Computer icon on the Desktop and select Properties, Advanced,
Start-Up and Recovery, System Failure and uncheck box before
Automatically Restart.

Do not re-enable automatic restart on system failure. Check for
variants of the Stop Error message.

Watch the sequence of messages when you attempt to boot. You will need
to be patient because from what you say the problem is intermitent. In
particular is the BIOS failing to detect one or more hard drives? This
link describes the sequence of stages when a computer boots.

Are there any Error reports in the system log?

You can access Event Viewer by selecting Start, Control Panel,
Administrative Tools, and Event Viewer. When researching the meaning
of the error, information regarding Event ID, Source and Description
are important.

A tip for posting copies of Error Reports! Run Event Viewer and double
click on the error you want to copy. In the window, which appears is a
button resembling two pages. Click the button and close Event
Viewer.Now start your message (email) and do a paste into the body of
the message. Make sure this is the first paste after exiting from
Event Viewer.

Are there any yellow question marks in Device Manager? Right click on
the My Computer icon on your Desktop and select Properties,
Hardware,Device Manager. If yes what is the Device Error code?
