There is one problem with the Speccy Snapshot. It will occasionally throw figures that are not consistent with other figures. In this case it shows the following temperatures:
Obviously the motherboard temperature is unrealistic. If the temperature of the motherboard was anywhere close to this figure the CPU's temperature would reflect this overheating as well. But in order to get a "second opinion" please download, install, and run CPUIDHM.
I see that you upgraded the GPU to a NVIDIA GeForce GTX 970. This GPU requires at least a 500W PSU. Unfortunately the Speccy does not include the make and model of the PSU so I don't know what came with this computer. Did you upgrade the PSU to be sufficient with this GPU?
Did you download and install a bunch of third party programs on this computer. There are two things that can slow down a new computer, the bloatware which came with it and third party applications which are embedded in a great deal of program downloads now days. If you do the following you can find and remove any of these third party appls.
Please run AdwCleaner
Please download AdwCleaner and install it.
When AdwCleaner opens you will see an image like the one below.
Click on Scan to start the scan.
Once the search is complete a list of the pending items will be displayed. If you see any which you do not want removed, remove the check mark next to it.
If there are no malicious programs are found you will receive the following message.
Click on Clean to remove the selected items. If you have any questions about any items in the list please copy and paste the list in your topic so we can review it.
You will receive a message telling you that all programs will be closed so that the infections can be removed. Click on OK. The computer will be restarted to complete the cleaning process.
When the cleaning process is complete a log of what was removed will be presented. Please copy and the paste this log in your topic.
Please download and install Junkware Removal Tool.
Open your browser and go to Downloads, then click on the Junkware Removal Tool to install it.
Click on Run to initiate the installation.
To avoid potential conflicts, temporarily disable your antivirus and firewall. You will want to be offline when you do this.
Run the tool by double-clicking it. If you are using Windows Vista, 7, or 8; instead of double-clicking, right-mouse click JRT.exe and select Run as Administrator.
The tool will open and start scanning your system.
Please be patient as this can take a while to complete depending on your system's specifications.
On completion, a log (JRT.txt) is saved to your desktop and will automatically open. Copy and this and then post this in your topic.
