Thank you for the additional information
Can you also provide the PSU (power supply unit) details, brand and model name or number please.
Can you please watch a video for a few moments and then run Speedfan, take a screenshot and attach it to your next reply so that your temps and voltages can be checked, see below;
and install it. Once it's installed, run the program and post here the information it shows. The information I want you to post is the stuff that is circled in the example picture I have attached.
If you are running on a vista machine, please go to where you installed the program and run the program as administrator. (this is a screenshot from a vista machine)
To capture and post a screenshot;
Click on the ALT key + PRT SCR key..its on the top row..right hand side..now click on start...all programs...accessories...paint....left click in the white area ...press CTRL + V...click on file...click on save...save it to your desktop...name it something related to the screen your capturing... BE SURE TO SAVE IT AS A .JPG ...otherwise it may be to big to upload... then after typing in any response you have... click on browse...desktop...find the screenshot..select it and click on the upload button...then on the lower left...after it says upload successful...click on add reply like you normally would.
Depending on the results we may need to run a second diagnostic tool in order to confirm the readings.
