Computer shutting down before booting

[T Dutson]

My computer shuts down before fully booting, even in safe mode. I have
fitted a new CPU cooler and cleaned the PSU fans but still cannot boot. The
problem started when I fitted a new CPU cooler. The computer would
eventually only work when on its side (?) and then refused to boot. I have
since fitted a new cooler which is rated to Athlon 3500XP+ with no
improvement.

Gigabyte GA-7VKMP mainboard
Athlon XP 2000+
512 MB DDR RAM
Maxtor 40GB UDMA HDD
300 Watt PSU
AOpen 52 x 24 x 52x CDRW
Windows 98SE

Any suggestions gratefully appreciated.

Terry - Your symptom points to a bad power supply. However, as the system
was at one point working "on its side", you might want to uninstall and
reinstall the mainboard to make sure that something didn't get lodged under
there to short it out. Still, I'd be surprised if a new power supply
doesn't correct this.

Something else you need to be aware of is that most mainboards will shut
down if they don't sense the CPU fan running OR sense that the CPU fan is
running too slow. -Dave

this sounds typically like a reversed HS install....backwards, and an air
gap exists between the chip and the HS
