Well, 110°C is too high, even for a graphics card. The 47 and 48 are fine but the 84 and 61 are concerning. But I think we still need to sort out what is being monitored. SpeedFan is a good program but not suitable for all systems and these programs often have a hard time matching sensor to the correct label. Below is my canned text on hardware monitors. See if you can get your labels sorted out.
You also need to open the side panel and make sure all fans are spinning. Then power down and unplug, discharge any static in your body by touching bare metal of the case, then carefully clean the interior of heat trapping dust and dirt.
Your motherboard utilities disk should have a monitoring program (or check for a more recent version on your motherboard or PC maker's website). If none, I recommend CoreTemp
for newer Intel and AMD64 CPUs, or http://www.techpowerup.com/realtemp/'

for Intels. SpeedFan
is a great and popular alternative, or
you can try Motherboard Monitor
. Unfortunately, I have found that these programs often have problems properly identifying and labeling the sensor they are reading. The temperatures shown are as accurate as the inexpensive, low-tech sensors will allow, but it may say System Fan instead of CPU Fan. Fortunately, the programs do allow you to edit the labels, so I use Everest
to verify the temperatures (as it is able to match sensor with label correctly), then edit the label in the monitoring program. In Everest, look under Computer > Sensor, then wait a couple seconds for the readings to appear. Unfortunately, Everest does not minimize to the system tray to show real-time temperatures, otherwise, you could use Everest instead of the others. Check but do not rely on the temps shown in the BIOS Setup Menu. While they are likely correct, running the BIOS Setup Menu is probably the least demanding task you can ask of your computer so it does not show the temps when the system is being taxed. But if the BIOS Setup Menu temps are high, you have problem that needs to be corrected.
Once your temps are sorted out and under control, if still having rebooting problems we can look at malware, RAM or other possible causes. But the priority is the 110° and 84° temps that need to be addressed.
