I have a windows vista that boots OK, but after about 30 minutes the screen
becomes a bit distorted and the PC freezes. I cannot move mouse/keyboard
nor can I ping it. In safe mode it doesnt lock up.
Trying to find where to look. I have disbaled most startup apps and it
still locks up in normal mode.
Any suggestions ??

Just a guess but my first reaction would be to check for new graphics card
driver updates.

yes safe mode with network works without lockup. It is an HP with
integrated video and nic
 
Which firewall, anti-virus, anti-spyware or security suite is installed?
There are some that cause problems which don't always appear immediately.
 
It has Mcafee. I turned it off in startup and services for testing. I
disabled the wwindows fireall also.
I am attempting a repair as it came up on last boot with the computer was
unable to start screen. It has been at attempting repair for the past
hour..
 
Do you think that is causing the lockups though? I agree with your comments
on mcafee, but this is a freinds PC so I would rather do that after th
lockup problem is cleared up

The problem you have sounds to me like hardware, especially your video
card, as others in this thread have already suggested.

This kind of thing has never happened to me with Norton, and I just don't
believe that McAfee would do it either.

If you were running a program I had written, maybe I could have left a
memory leak in to cause that kind of behavior. But then, maybe not - I was
pretty careful about such things, and so are Norton and McAfee - usually
:-)

Blanket statements like "McAfee and Norton are junk" don't necessarily
represent everyone's experience...
 
Is this a laptop? If so, the internal fan(s) may not be providing enough
cooling. (Dust buildup, sticky bearings, etc)
If the machine is a desktop, adequate cooling may be an issue, as is
memory timing and operating voltage.

A laptop may use video memory that is actually part of the main memory,
so main memory can be an issue as well, when you start looking at the
video distortion. Temperature control of the video card components can
also be an issue.
 
This is an HP desktop all fans are running and cover is now off. I have
enabled all starttup items and disabled all startup services in msconfig and
it has been running for hours. How to find out which service , It would
take some time to do them 1 at a time

Don't do it one at a time. Enable half, leaving half disabled. If it's
still OK, then enable half of the currently disabled half. If it fails,
disable half of the enabled half. Rinse and repeat, dividing the suspect
part in half each time.

It's a binary search...
