Hi,
You reallly need to list your specs including motherboard, cpu, video card, brand name and wattage of your power supply, drives....etc. etc. etc....you get the picture.
In the meantime, I would suggest that you monitor and list your temps for at-rest and under-stress usage. Another crucial area is that you need to check your voltages for this computer. Most modern day motherboards (since we don't know what you have, can't tell) have a program that will tell these readings. However, if yours does not, here are a couple of free programs that will help.
