Just built a new computer for my cousin for christmas and
have a bug i can't seem to get rid of and I'm running out
of time...... During running win xp prof, the computer
will shut down and reboot for no apparent reason...
checking event viewer, there is an info message
saying "the computer has rebooted from a bugcheck. The
bugcheck was 0x1000007e 0xc0000005,0xf19b6729,0xfa6776fo,
0xfa6778fo). A dump was saved in C...... I've run out
of ideas... i've changed out freaking every component on
the computer except the motherboard... which i can't seem
to get any support from them, the board is an ASUS P4R800-
VM, I've got a celeron 2.4, 256 kingston ram, integrated
ati vid and sound on the board. No PCI cards... thanks
for any help or suggestions..

Disable the onboard video and try a different video card. Are all your
drivers up to date..?
 
Right click My Computer, Properties, Advanced, then in the Startup and
Recovery Section click Settings. You can uncheck "Automatically Restart" .
 
A long shot, but check the output voltage of the PSU. If
it's not within toerances for the Mboard & CPU, it will
cause a reboot. Also, is it at least 350w..if you have a
lot of hardware installed, it may be insuffcient.

i have got a 500w cheap power supply, no pci cards to draw much current, but thinking that might be the culprit i bought an antec 400w unit, and did some swapping with no change... i'm really leaning toward motherboard and maybe ati vid chip, haven't been able to find any drivers for it on the internet other than what came on the mb cd... it seems that the mb i have is a new model, and not an expensive one and the support for it is crap, i changed the startup recovery setting to not auto restart, i then clicked on IE and my computer rebooted...arrrgghhhh.... countdown to christmas day is ticking..... i'll try a separate vid card and see, any more suggestions greatly appreciated...
thanks,

If you have any case fans runnibg - disconnect them and give it a try.
Another thing to check is make sure your cpu heatsink is sitting perfectly
flat on the chip. Some heatsinks have one edge machined out to clear the cpu
mount.

It's possible you might be overheating the cpu. Go into bios and check the
cpu temperature.

Not so much of a long shot. Had an HP Pavillion that had
the exact same problem. Replaced memory, motherboard,
etc. Finally, power supply swap fixed the problem
permanently.
 
Unchecking "Automatically Restart" might stop the
rebooting, but the computer will still still shut down. It
will now most likely stop with the Blue Screen which may
give an error message. I believe this is a function of
newer Microsoft operation systems which halts the system
on errors, but it can be a royal pain since it doesn't
give clear direction on the "problem".
You can search the Microsoft Knowlege Base for possible
causes of the error but if you Google search the error you
will probably find thousands of people with the same
problem. You might get lucky.
I have had a similar problem for 1 1/2 years on an ASUS
P4T533. I finally found a forum thread which in this case
claims the problem is the board itself and well known to
ASUS. I am returning the board to ASUS for repair.
In your case search the first segment of the bug check
string (0x1000007e) in the Knowlege base. There is a page
somewhere on the MSKB that sort of explains what the
message segments are supposed to mean. I can't find it
right now but will look later if you are interested.
