When the CPU load significantly decreases FPS in games.

Good day! Have a laptop Acer Aspire V5-572G with features:
CPU: Intel Core i7-3537U
RAM: 2 strap: 2 + 4 GB, frequency of 1600
Graphics: Nvidia Geforce GT750M
The question is: what could be the reason for "sagging" in games, when the load on the processor? It happens this way: After 5-10 min. stable game fps drops significantly for a short period of time(about 5-10 sec.) after, fps restores their previous values, but again, after less than a minute, the situation is repeated. As an example, post links to videos that have been recorded by such sagging.

The same thing is happening with all games from 2009 - 2016, with a difference only in time, "sagging" from this "visav". Before special attention is not paid(notebook year), "treated" these hang by drastically reducing the load, for example, while Cycling certain games menu(in the video example with The thing you should know about 3), it took one second after "juggling" fps recovered, but now has decided to change the situation, hoping that you will help to understand what could be the reason.
The laptop suffered change the OS four times and win.8, and two assemblies of win.10 and of course 7 was(literally 2 hours ago), the problem was everywhere identical, then: upgrade the BIOS from 2.06 to 2.10 - change no, defragmenting the hard disk - no changes, clean OS(although put on a clean game) - there are no changes, cleaning the dust, to install different versions of drivers for integrated and discrete graphics card - no change. All service packs for wine, direct x, framework and the visuals were respectively installed. The most fresh. - no change. Well, after all the changes all - this appeared to only increase fps, but sagging remains, and in some games they have acquired a different character(for example CS:GO freezes as well as The Witcher, in the video the fps falls to 10-15 like it was before I spent the above steps, and 2-3. What exactly is in this case influenced the work of, say can not) the Problem, as I understand it, somewhere in the hardware, possibly the BIOS settings or "embedded" CPU overclocking, maybe even food. Temperature, I think, for the processor and video card when games acceptable: GP: 80 - 88С, CPU:80-90C, and therefore also rule out overheating. The filling for the ultrabook are very good and show the first minutes of the game, and also some subsequent "train" may well "pull" of the game, but abnormal sagging are deplorable. Guys get tired of such lags, honestly.

UPD_01:

The worst thing for me is that your own computer is no longer your own and begins to live "my life", because on the other to describe the following I do not dare, his actions defy my logic. At the moment there is only one game that behaved exactly the same on the other axes, but after a long time of the game even with the existing bugs, glitches, like a snowball, still grew, to the point that now does not save previously described method of "juggling", and misiti starts later, well, moments to five minutes of stable game. The temperature thus retains all its normal readings. After restarting the game, the game itself(!) selects the integrated graphics instead of discrete, and naturally the brakes there supernatural, and no coercive measures to run the game with discrete't help in this case is just restart. After the reboot, the story is repeated, until a new restart. After one of the reboots, I was able to play without freezes for about two hours, the story is not repeated. Just noticed that without the Frisians download GP reaches 90-100%, but as soon as the "heat", the download GP starts to waver between 30-60%, which may be the cause of the hang. The only thing is that well I can not understand what was going on. Or temperature indicators lying to me, or it's in discrete way to come to an end. Except the Witcher, heavy applications, unfortunately, not available. He described all this in order that maybe anyone of you has faced similar, it is likely that you have found a method of treatment and they share. =)

UPD_02:

An interesting feature when disconnecting power from laptop: download GP at 99-100%, when the temperature is lowered to 60 degrees, and, surprisingly shows statistics, I have the wildest glitches, BUT as soon as the temperature is raised to 70-72 GP, the freezes stop and the game goes naplavnye, but only for a minute, no more.

I would say not looking any content the problem is caused by recording the video but peck.
finally in this can be blame for dis hard SSD or otheruse
as option 2 is overheating something. processor or graphics card
I have something similar happening in vicnaire edokov after 6 hours of play and I thought that for some reason stops working, if.
try to go somewhere in settings of the system performance. on the system disk set the paging file gigs so on 16-20. if not help then peck.

Defragler says that all is well with the hard pace. 38-41 him. You can, of course, sin on overheating, but the temperature is stable for CPU and for graphics card under such loads, although, perhaps, with this "heat" here, shake a leg, his appointment "ultrabounce" which would not intended for games, but again with similar problems on this laptop, on the Internet, nobody faced, so that's not the purpose of business. I doubt that the paging file will solve the problem, because earlier it was assigned a value of 10 GB., try 16-20, but my heart tells me that this is not salt.

if the laptop does not slow down the laptop itself that inhibits his hard drive and leads to all kinds of friezes and a long reverie.

Okay, I'll take your advice. As it is possible to change the drive, change, test. Paging, by the way, nothing has changed. If you have any more tips, then I will be glad to apply them, suddenly something works.

The owner of the laptop, just for the i5, the problem is that the hard drive is very slow, Yes, it, I, too, had such friezes. I realized that this is hard drive after playing GTA5 and Armu 3, SSD saved the day. I understand that perhaps a little late, but still)

but the author's theme percent energy saving.. there stupidly lacking frequency and the CPU chokes. as a result, the fps drops.. in the Witcher for example in the white garden in the home village where his CPU a little.. in Novigrad and toussainte he's probably the slide show word))

Yes, the laptop has long been sold. The cause was never found, but I sin on overheating + install new hard.
