You say that Your PSU's +12V drops down to 4-5V?!

It looks like You have a faulty/damaged or overloaded PSU , if so it might cause serious damage to other components as well.
Usually the motherboard gets damaged by faulty PSU's as it is directly connected to the PSU and most electrical deployment is regulated by the motherboard.
As for the CPU's high temperature , what kind of CPU is it?
You can use Log in to see links to find out if You don't know. Log in to see links and prior are single executable files , no installation needed.
Possibilities:
-if the PSU is faulty , the extreme drop of Voltage output might cause unexpected heat buildup as the components due to the lack of sufficient Voltage try to keep running by pulling more Watts from the PSU. More Watts flowing causes more heat being generated and the PSU gets overloaded even more resulting in further Voltage drop.
SOMETHING LIKE THAT , I'm not an electrician so I might be wrong.
-if the PSU is NOT faulty then Your CPU might experience heat-buildup due to aged thermal grease.
Even worse if Your CPU's cooler got the original Intel "stuff" on it - surely better than air/nothing , but that stuff is just wrong!
The solution would be to take of the CPU's cooler , clean neatly both cooler and CPU , spread a THIN layer of Silicon or Silver thermal grease on both and put it back together.
This certainly requires some do-it-yourself knowledge and if You think You CAN'T do it then DON'T - find someone to do it for You.
The later does not explain , nor can it be the cause of the enormous Voltage drop of Your PSU though.
A new PSU does not cost much , if there is a chance that it is damaged replace it sooner rather than later!
I have seen burnt-out motherboards , GPU's , CPU's and RAM's - these components require properly regulated Voltages and faulty PSU's damage them easily.
Hard and optical drives usually get spared as they aren't so sensitive.
P.S.: According to NVIDIA that graphic card (Geforce 9500GT) requires a minimal 350W PSU - that means TRUE 350W.
If You have a power hungry CPU as well then the minimal Wattage must be risen accordingly , otherwise You might encounter system instabilities!Last edited by Wilhelm; 11-07-2011 at 02:57 PM.
