mins after i turn on my computer and get on a game so
notreally enough time to overheat. And the system isnt
overclocked. Ill look into it though so thanks for the help.
<Make sure it's not overheating>
Hey, five minutes without a fan is all the Pentium 4 needs to overheat.
Take off the heatsink and your processor can reach 200 degrees
Fahrenheit in a matter of SECONDS. In fact, the Pentium 4 processor
puts out more heat per square centimeter than a nuclear reactor (Maximum
PC, January 2004 issue). If you have a Prescott-core P4, it will
overheat even faster than the commonplace Northwood and Williamette cores.
Where am I going with this? Even if you don't have a P4, don't rule out
overheating. Like I said, the next time your computer reboots, take the
side door off and touch the metal heatsink on your processor. If it's
hot, make sure your system's fans are running. If it's not hot, then
you may need a new power supply.
Also check the heatsink on your video card's GPU.
<Adjust Thermal Delay (HT Pentium 4 C-revisions only)>
If you don't have a hyper-threading Pentium 4 with an 800MHz FSB and
512KB of L2 cache, skip this step.
Turn off your computer and wait a few minutes. Grab a stopwatch and
turn it on. Stop the watch when Windows finishes loading and the hard
drive calms down, signifying that you're ready to go. Next, reboot and
enter your system's BIOS and find an option called "Delay Prior to
Thermal." Take the time it takes to boot, and set the delay for that
time, rounded up to the nearest choice. Generally, it should be set for
four minutes.
What DPTT does is have the chipset wait for the delay to expire before
monitoring the CPU's temperature. When the temp. exceeds 38C/100F, the
chipset begins mixing in HALT signals to cool the CPU down. Depending
on the temperature recorded by the on-die sensor, 50 to 70 percent of
your CPU time is taken up by this involuntary cooling method.
If your system overheats after you turn it on, decrease the delay. Four
minutes is the minimum. Don't start gaming until these four minutes
have expired.
<Check the power supply>
Erratic voltages and sudden drops in Vcore or Vdimm can reboot your
computer. Google the term "Motherboard Monitor 5." Run a CPU-intensive
program like Prime95 (
www.mersenne.org), Folding@Home or 3Dmark2003 and
keep an eye on the voltages. Generally, they shouldn't vary more than
5% at any time.
Plus, by running Prime95, you might find the world's largest prime
number, and by running Folding@Home, you're studying protein folding to
help cure diseases. If you can't solve your computer problem, at least
you'll feel like you've done something to help mankind (or mathematicians).
<Check the outlet... really>
It may be your house's fault. Before you buy a new PSU, check the
outlet it's plugged into. Computers don't use transforming PSU's like
most appliances, they use switching PSU's. It's more energy-efficient,
however all but the most expensive PSU's condition the incoming voltage.
Line noise and spikes/surges/drops in the incoming voltage can also
cause rebooting. Plug your computer into a different outlet. If it
still acts up, try a different circuit (usually a different room).
