It may be difficult to measure the temps of the VRMs. Take the side of your case off and aim a common household fan into it; retest. If that helps, something like an Antec Spotcool aimed at the VRMs might work. What motherboard do you have? Does it have heat sinks on its VRMs?

This is often the result of something overheating, which could also be your CPU or the VRMs on your motherboard. What are your CPU temps?
It is also possible, but less likely, that you've got some malware on your system that occasionally cranks up, e.g. to send out spam. MalwareBytes is a free scanner that should be able to find and eradicate anything like that.

dont know about the malware but my cpu temp are also normal when this happens...and even at first i thought that it was an heating issue so i switched off my pc for about 30mins and then resumed..as soon as i started ac4 after 2 or 3 mins of gaming it happened again.. and it keeps on happening after 2-3 mins intervals..this goes for all games

Your system may not recognize joystick input as sufficient to keep your system running at its normal speed, so it may be idling down (despite running a game). A program like MSI Afterburner can keep track of your clock speeds. If they're ramping down after a particular period of time, that may be the issue. You might be able to adjust your performance settings under "Power" in Control Panel. Does your joystick use an older joystick port, or is it USB?

If this is a new issue, something has changes.
Some possibilities:

1. your cpu or gpu are throttling. See if you can't trace them.
2. Some function is interfering such as a virus scan, malware, update, etc... Run the windows task manager and see if anything is conflicting.
3. Perhaps there is a hard drive issue. If a hard drive runs out of good sectors for an update, you can slow down.
Run the drive diagnostic for your hard drive. I found an interesting chart from Samsung showing fps dropw with a hard drive that do not occur with a ssd
http://www.samsung.com/global/business/semiconductor/minisite/SSD/global/html/why/forGamer.html
4. If the drops are with online gaming, it is likely internet related.

Geo, he said tapping the keyboard stops the problem.
You might check and see if you are using the latest / correct drivers for your joystick. Perhaps a Microsoft update has introduced a bug that altered its function. The manufacturer may have a fix. If it's been reported to Microsoft, they may have a KB article on it possibly containing a fix.

That is good,(he posted that while I was slow composing my post)
I wonder if a Xbox 360 controller is not simply a usb joystick, but is sending extra signals designed for the xbox.
He might try a normal pc joystick to see if that makes a difference.

i have analyzed the issue and frankly found it to be really weird actually.. when my system does not take any input from my keyboard or mouse.. irrespective of any game or app running ..if its idle..after 2mins exactly the cpu and gpu load goes to 100% suddenly and when i move my mouse or press a button the load goes down to zero and the funny thing is if i keep the taskmanager on this issue does not take place where as if i switch it off.. there we go again full load after 2mins exactly provided i dont move the mouse or use my keyboard..

You either have a bad driver (e.g. sound), or possibly a malware infection, that grabs your system to do something when it thinks it may be idle. Since both CPU and GPU are being maxed, I'd suspect a cryptocurrency miner over something like a spambot. Run MalwareBytes on your system to check.

Could windows be indexing for search?
That takes much cpu normally when nothing else is going on.
I think that is the default when not much else is going on.
See what you have specified in control panel/indexing options.
Index only what you might search on.
