Do I suddenly have less CPU or something?

In the past few days I have noticed that my CPU is maxed out more easily than usual. Usually I could've had google chrome playing a video while playing hearthstone and the CPU would reach like 70% usage max. Now from some reason the programs can jump in CPU usage like crazy, for instance right now for about 2 seconds chrome used about 60% of my CPU playing only one video with no other tab open.

Now it is basically impossible to play hearthstone and have a video play without the CPU reaching 100% and lagging everything(that happens every 30 seconds or so).

Should I just go upgrade my CPU? As far as I know it is quite old.

You can go over your install closely using the Troubleshooting Steps for Windows 7
which has a step for tracing CPU usage.

Compare your install to the perfect install compiled in Clean Reinstall - Factory OEM Windows 7 which has everything that works best for Win7 since beta in tens of thousands of installs we've directly helped do here.

I would try a reinstall if you can't tame the CPU otherwise. Do a perfect reinstall phasing each set of Updates, then each program, with time in between to monitor performance changes. Don't import any drivers except the ones delivered by Windows Update when you enable Automatically deliver drivers via Windows Update (Step 3), then after all rounds of Updates are done and no more offered import any drivers still missing in Device Manager. This can pinpoint an Update, driver, program or setting change that is causing problems.

I would like to stress that I am really, really bad at understanding the steps of most tutorials. I know it seems simple and easy but for me it is not so I would have to be guided step by step.

The first step is "1. Test the hard drive using maker's HD Diagnostics diagnostics/repair extended CD scan. Burn ISO to CD using Windows Image Burner then boot the disk to run extended Scan. Then run a full Disk Check on all partitions, if necessary from System Recovery Options Command Line."

Where do I get the ISO file?

" In Windows VISTA/Windows 7 - Go to Start...and type in "devmgmt.msc" (without the quotes) and press Enter."
My search function does not work because my OS is in hebrew. Where do I find it?

Type Device Manager in Start search box, or right click Computer to choose Manage then to choose Dev Mgr.

It says "Click on the + sign next to Disk Drives and use Google to search the information listed there."

What exactly do I need to do? Which drives do I search and which information do I need?

So do I take the fast or the long test? Also it says I need to have backup of my information, what do I do?
