Getting hardware BSOD's, need to figure out what isn't working

[Deganveran]

I am running an ABIT IP-95 mobo with a 3.20 ghz intel dual core. I have an Orion 550 watt PSU (four years old). I recently PSU came with the comp with is about 3 to 4 years old. Nothing is overclocked. I recently installed new ram and did a clean new HD install so those are fine. Is there any way I can tell what is giving me the BSOD's without systamatically buying and replacing the PSU, mobo, processor, network card, sound card or video card?

For example: With the temps of the PSU can I tell if that is the problem or not?

Here is the temps:

CPU Vcore: 1.248 v
Vdimm: 1.776
+ 3.3v: 3.248
+5v: 5.026v
VBat: 3.216
CPU Fan speed: 2351
Sys fan: 0
Pwr fan: 0
Cpu Temp: 143 F
Sys temp: 130 F

CPU temp 61.7°C seems a bit high, if not running any high intense programs

Try removing all internal dust using high compressed air can (commonly purchased from electronic or computer service workshops)
