Back in Device Manager are there any hidden devices with warnings, that is on the view tab in device manager, click to show hidden devices. If so what please.
If possible resolve those issues if there are any,
Then go as follows please.
1. Please see this link.http://h10025.www1.h...54&lang=en#N453
It is the spec for your computer.
2. Please open the case and check that the fan on the graphics card is clean and the other fans are clean. especially of course the CPU fan and cooling fins.
A very soft brush is ideal, do NOT use a vacuum cleaner. If you have an air duster spray, exercise caution when spraying fans, the air duster can cause them to spin so fast that it destroys the bush in which the fan runs.
I DO NOT THINK THIS IS THE PROBLEM, but a check will do no harm.
3. I notice that the computer was supplied with either the integrated graphics on the motherboard, or this Nvidia card.
Enter BIOS normally F2 on post and ensure that integrated graphics is DISABLED.
4.GO to this link and try this Unified driver graphics update from HP.
Follow carefully the instructions for downloading and installing please - view directions heading at the top of the driver notes.http://h10025.www1.h...ct=3550554#N180
