Yup..like I said...
"Also download tools to monitor the temperature of your processor and GPU too, check if you have temperature issues."
my cpu when idle is 50-55 c and when under load 70-80 c and my gpu when idle is 45c and when underload 70c
Way too hot for that CPU and GPU under load! Even when idle, the CPU can be 10C lower. I have a partially retired Core 2 Quad Q6600 that has a stock speed of 2400 MhZ and I was able to OC it to 2700 MHZ and it never ran that hot under full load. I think it would hit 50-55C when at load and idle was 37C.
Then again, I also had the case open and a larger fan blowing over the entire MOBO, but, even when the case was closed, the CPU still did not generate that much heat.
For now, until you can replace that rig totally, do what I did and open the case to allow a larger volume of cooler air to circulate. Also, check your heat sink and clean it of any dust that has built up. Same with the CPU fan. Remove those if need be, remove the thermal paste and reapply a smaller amount (pea sized, as mentioned above). You gotta bring that heat down, but, honestly, anything above 75C for long periods of time may have done thermal damage to the CPU. Assuming a socket 775 mobo, you can find replacement cpus on eBay for under $50 for the same type of CPU or even a Core 2 Quad Q6600. However, keep in mind that the Core 2 Quads, if you do not ensure proper airflow will also generate heat at or near those levels. I was lucky in that the air where my machine was at was routinely chilly to begin with.
Something else to ponder: Airflow. Do you use a push pull config? If the CPU is forced to recycle already warm air...up go the temps. Common sense here. Making sure that there is cooler air being pulled in while the warmer air gets exhausted out (without that still warmer air being brought back in!) = much happier CPU.
Hope this helps!
For the GPU, same basic thing...TOO HOT. Pull the card and clean the fan and air intake of all dust and dirt. Make sure that the fan is free to spin as required and that the warmer air is pushed out of the case.
I do suspect that thermal damage has occurred with both the CPU and GPU.
In your BIOS, if there's any quick and quiet settings...disable them. You want the fans running 90-100%, even if they are a little noisy. In the GPU settings, you can also make the speed run higher. Push comes to shove...remove the case side panel and use a larger fan to recycle that hot air almost instantly. Have the air blowing on the CPU and GPU. (if it blows across the HDD, that's fine...those also get warm.
Bottom line: Your system is outdated badly...Save up to replace it.
