My laptop would appear to be running fairly hard(mildly warm and fan running fast) even without any CPU intensive applications(only google chrome and word). I have cleaned the dust out and it has not made any difference. When I use photoshop or solidworks it does not seem to be running too much harder. When I open task manager the cpu is running at 99%, but quickly shoots down. This is why I question could this be an invisible virus, because I wonder if it realises task manager has been opened and shuts off?
Another thing I have noticed is a windows error sound(the one you get when a program is asking to make a change to windows), but there is now window opened?
Any advice would be much appreciated.
The laptop is a Dell xpsl702x
 
Hi,

This seems to be a known issue with Windows 10 where task would be running at almost 100% even though it's on idle. But here are some troubleshooting steps that I can recommend.
- Start by doing a complete virus/malware clean up.
- Here's a link you can use for a guide: http://www.tomsguide.com/faq/id-1691891/removing-malware-proven-completely-remove-bitcoin-mining-malware.html
- Next is to run Windows Update and install all the important updates there is.
- Also uninstall any bloat wares that may effect the performance of your PC as well.
- If all these will not work last resort would be o run a complete factory reset.
