I like oranges! (no brain activity)

That idle temp is way too high, even for a laptop. Should be around 50-60 or even lower. I'd replace the thermal paste if I were you, I had the same problem last week. Laptop was hitting 95°C while playing a game so the processor ran at like 1.2 GHz instead of 2.9 and the GPU at 400 MHz instead of 800 MHz... Replaced the thermal paste on both and now it maxes out at 81°C on the GPU while not throttling down at all and the CPU stays at 2.9 GHz too.
 
Try googling the name of your laptop and who knowns that you're as lucky and me and find a full disassembly video of your laptop
 
But if you really want to be lazy you could try this http://www.techpowerup.com/downloads/2288/throttlestop-6-00/, you can limit your processor's frequency with it. But I don't think it will help much tbh.. 

no it's completely fine usually. It has an idle temp of 73 degrees then when I play a game that needs a lot of CPU power i will reach as high as 100 degrees which makes my CPU underclock itself to 20% power. If i can make my CPU only go to 90% power it would never reach 100 degrees and i would get decent enough fps but the range in which i can set my cpu power is 25% power, 50% power or 100% power

From few days after couple of hours playing i get weird lagging,even with keyboard,its logitech g11, and whenever i change volume from it its lags (which never happend before)...I thought it can be temperature issues,but everything looks "safe" to me...Yesterday with 32° in room cpu max temperature was 56° ,gpu 58° , motherboard 43° only hard disk was at limit 47° max (i heard over 50° you get problems) ...I also tried to clean pc with ccleaner,wise registry and tune up,also i i dont have any virus or malware (used malwarebytes and windows defender)...Any clue what it can be? Thanks

Did all that, didn't work  

upgrading the mobo + cpu now will be better than gpu (not more fps but to get the max out of the gpu )
