Windows system CPU usage stays at 100%

-3

I use Windows 7, system has been working fine except that lately its has become relatively slow.

I opened tasked manager and noticed the CPU usage stays on 100% even when the only opened application is google chrome.

I have tried scanning my system with Microsoft Endpoint Antivirus and other Anti Malware but nothing was discovered.

Am totally confused right now and considering the option of re-installing a fresh copy of Windows 7.

What could be the possible cause of this issue?

Have you checked this in clean boot or safe mode ? – pun – 2015-07-30T07:30:35.587

Might be a virus. There are viruses that use the resources of the infected computer to mine bitcoins. I would advice you to scan your system for malware. – Sid – 2015-07-30T08:34:37.720

Thanks to everyone. Even people that down voted me instead of answering my question. I have re installed my os and programs. Everything is okay. Thanks all. – Emeka Mbah – 2015-07-30T09:24:59.880

You should disable most of the applications that run at startup:

Run > msconfig > boot (uncheck all, exception made for your AV), reboot
