My CPU load is at 100% while gaming recently and I never had this problem before and even when I'm playing simple games like Deadpool.

I have an Intel Core i3 4150 and the temperature of the CPU rises to ~76 Degrees while gaming.

GeForce GT 730 GPU temp stays about 60degrees.

I have dusted everything.

What could be the cause of this?

Thanks!

What version of Windows are you running? Case cooling fans will help keep your temperatures down for everything, ie your motherboard, CPU, GPU, RAM, ect... so they are always a good idea. However cooling fans are not going to have anything to do with your CPU usage. If your CPU usage were only high in new demanding games I would say you may be bottlenecking, however running Deadpool your CPU should be no...

If this just happened out of the blue the very fist thing I would do is check for Malware. The malware may be running in the background during gaming to mask it from antivirus programs that run on "gaming mode" as to not interfere with your gaming experience. I would suggest running Malwarebytes as it is a free and robust malware removal tool. If your system is clean of malware then it may be hardware related ie motherboard or processor is dying. Neither of those things are very common, but it does happen.

The Intel Core i3 4150 should not bottle neck the GT 730. The 100% usage is most likely due other software issues causing the high CPU usage.

Run CCleaner and do the Clean and Registry portions both. You may have to run it more than once if the system is badly messed up.

Next, update your virus pgm and then run a FULL virus scan. Then run Malwarebytes and have it remove any bloatware that may have been installed on the system: http://www.malwarebytes.org/

Finally, check to see how much junk you can live without running in the background when Windows starts. Look in your tray to see how many items are running. Or on your task bar. For the best gaming experience, you want as little as possible to be going on when the CPU/GPU are stressed in a gaming environment.

Hope this helps!

Unfortunately anything that is mass produced can have a defect. Why out of 500,000 cars will one be a total lemon? It could be just about anything from a bent or improperly soldered connection to a fluke part failure. Has your power gone out lately, surges in electricity, brown outs? Even with a good surge protector such things can still damage fragile hardware components.

I would still start with running a full malware scan, maybe even restoring Windows to a date you know the computer was working well through windows restore. Hardware failures of that type are very rare (especially after only 6 months) so I'm still thinking its software related. You may also want to launch task manager and see if anything is using an abnormal amount of CPU.

Be very careful running "registry cleaners" they can often cause much more harm and problems then they "fix" no registry cleaner is actually recommended for Windows due to this problem. What version of Windows are you running? If you just updated to Windows 10 do you have all the updates? Have you clean installed Windows 10 after update? Even if not on Windows 10 try running windows update. More than likely you have gotten a malware infection. As I mentioned above Malwarebytes is a great cleaning tool. Launch Malwarebytes, run its update utility and then select custom scan, Scan the entire drive you have Windows installed on, it will take probably an hour to an hour and half (depending on size of drive).

I've never had an issue with the CCleaner Registry Cleaner.

Just did a little research, CCleaner Registry Cleaner should be okay to use as DevinDerpsYT said. There is a lot of debate over if cleaning the registry is needed or to just leave it be, so use at your own risk, however CCleaner is a less invasive registry cleaner. I have in the past used RegCure Pro, it is a much more invasive registry cleaner and actually caused enough problems I had to do a full format and clean install back when I was on Windows 7.

The best first step is to ensure you don't have any malware. I just remembered something too, when I first updated to Windows 10 there is a background process called Runtime Broker (launch task manager to view it) and it was using over 20% CPU at idle without me running anything. I believe Windows 8, 8.1, and 10 all have Runtime Broker running in the background. The only thing that really fixed Runtime Broker's issue for me was to do a clean install of Windows 10 after the update. If you find no malware present on your system, if you try CCleaner but still have same issue, you may want to back up your important data and do a clean install of your operating system. If after a clean install you still have the same problem then you may be looking at a rare hardware failure. A clean install will guarantee you have no malware present, you have no registry problems, and you have no software conflicts.

Thanks guys
i have just run Malwarebyte : some PUP found, Avast no issues found, run Ccleaner.

I'm thinking of making a clean install.

What if i add some new fans?
Well im in summer and the room temp is near 32-35 degrees. Do i need to consider these?


While using google chrome my CPU usage is only 2% and temp 35-40.

What version of Windows are you running? Case cooling fans will help keep your temperatures down for everything, ie your motherboard, CPU, GPU, RAM, ect... so they are always a good idea. However cooling fans are not going to have anything to do with your CPU usage. If your CPU usage were only high in new demanding games I would say you may be bottlenecking, however running Deadpool your CPU should be no where near 100%. Older versions of Windows its best to boot from install disk, format everything and do a clean install (after backing up important files and pictures of course). If your on windows 10 then you want to go to the following page:
https://www.microsoft.com/en-us/software-download/windows10
You will want to create a USB, DVD, ISO by clicking download tool now. If you already have Windows 10 on your system boot with the USB or DVD in the drive and boot from the DVD or USB (may have to tell your BIOS to do so) and simply tell it to format and remove all files and programs and go through reinstall process and you will have a clean install of Windows 10. If you still on Windows 7-8.1 and want to upgrade to Windows 10 first Update through Windows Update and run it that way so your product key is written for Windows 10, after fully installed then boot with the DVD or USB and go through clean install process.

Believe it or not, it probably wasn't Malware. if it were Malwarebytes would have found it, its a great utility, make sure you reload it and run from time to time. What it probably was is residual "stuff" coming along from your previous OS into Windows 10. To make it simple Microsoft just has everyone update to Windows 10 and that is just that, however they should really tell people that they need to do a clean install afterwards to get the best performance out of Windows 10. If they did that though people are going to be upset about loosing personal data and have backup problems, so Microsoft doesn't really tell people they should do a clean install.

Best of luck to you, and enjoy your system again. After a clean install Windows 10 is actually a really good OS.
