1. 400W PSUs are rarely 400. It's why I skip all that and move to 450 or bigger. I don't think this is your issue, but always note it. Reference -> http://www.tomshardware.com/howto/20021021/
2. Pull the case cover off, point a fan at the internals and retest. If you don't do this, we'll never know.

hello.. i am having wierd problems...
well 1st of all my computer just switches off randomly (not shutdown) on its own and then doesnt turn back on for a few minutes.. unless i switch off - on the SMPS.
Also sometimes after reboot i get wierd beeps from my radeon card saying that its power is not connected.
then after trying 2-3 times it works and the computer boots..
and now lately ive been getting (although rarely )high frequency whining (similar to the noise of the cpu fan on high RPM) noises from my HDD and i get blue screen errors on atapi.sys
here is my configuration
local company 400W SMPS
AMD Athlon XP 2000+
MSI KT4AV (KT400A)
266mhz 512mb DDR RAM
Sony DRU530A DVD-RW
Samsung 52Max CD-ROM
ATI Radeon 9800
Seagate Baracuda 40GB HDD
Samsung 20GB
