I'm working on a friend's 6-month old computer. It has an Athlon 64-bit
dual-core 4200 chip and running XP SP3 with 1 Gb RAM.
It has suddenly stopped booting into Windows. As soon as it is past the
bios stage, it cuts out as if the power has been cut.
I suspected overheating, so I got into Bios and checked temps. The cpu,
with only bios loaded, is slowly building up to 75c. At that point the
power cuts out---I guess it's set to do so.
My guess therefore is that as soon as XP starts to load, cpu temperature
may be increasing within a few seconds to the point where power cuts
out. Taking the sides off, the cpu is almost too hot to touch.
If I power off, blow air in via a desk fan, and wait several minutes for
the system to cool, it will remain in bios for several minutes before
cutting out. If I immediately try to reboot, it will cut out almost
immediately. So it looks to me like a cpu overheating problem which is
causing the boot failure.
What could be causing the cpu to overheat so rapidly? Faulty power supply?
It's only 6 months old!
