I don't know that this is called so i am starting the topic so sorry in advance if its already there. so I Recently faced this problem and still its going on. Some times the application that i use show this weird grains on them. as u can see the title bar of WhatsApp is weird even around WhatsApp u can see. You can even see this in WarFrame launcher. So far i have tried uninstalling and deleting the driver and its files completely from device manager. i reinstalled the driver but this isn't solving the problem. m scared that my gpu is broken. or something is wrong with my laptop. its HP laptop with 8gb ram win 10 64 bit i5 7200U 940mx NVidia GPU. Also recently my BIOS crashed i think and it recovered on its own but my windows broke for some reason. So i reinstalled the windows 2004 version. So far i have seen this in 3 things WhatsApp from win store, Microsoft teams and WarFrame launcher. also whenever i hop the mouse over to this pixels it goes back to normal, like it was never there. I don't know that to do now so m concerned.

Can u advice me on building a pc for my sis , she is graphics designer but i wanna make a pc on budget without gpu. so i wanna build something within 25k rupees without gpu and HDD. Ram,cpu and mb . Also i ll add gpu on the way . I also have case of old pc. Some of the components in US arnt WIDELY available like ryzen 3 supported motherboards. There are MB which supports 1st and 2nd gen but no MB says that it supports 3rd gen mb i have to upgrade BIOS.... If u can get help it wud be appreciated. Sry for bad English

So I need to buy a cheap SSD and a graphic card ??

I mean fan doesn't freely spin like one of process or 2 fans that I have when u rotate them . The GPU was used for graphics design. But I sometimes play games on it. Also recently system has become slow idk what's problem I even clean install new OS AND IT STILL TAKING 2mins to log in. Like I said this is happening since 2-3 days it was working fine before

Like I told u fan is struggling to run sometimes I have to make it run with pencil ... Idk I even add coolant oil

Recently I cleaned my pc. And did some wire management like Linus always tells us to do and when I usually started playing game (paladins) I saw a ridiculous fps drop I used to get >100 fps in this game. Now this kind of lag is weird it shows me like this. 65fps 63ping ->. 25ms This 25 ms is GPU response time according to the command I used /stat unit in unreal engine 3 game. I used to get 5-10 ms and how this drop is happening is when I get 5-10 ms I get more fps and it significant drops to 25 and even crashes windows with more 45ms or more. I checked and saw that fan on my GPU 610 get was struggling to move. Shud I add a fan like Linus did in that video bc fan of my GPU sent available anymore. Bc fan isn't spinning that much GPU is becoming hotter and hotter I saw 91'C today yesterday it was 103'C Btw I have a designer pc i5 3450 8 GB ram GT 610 Also I tried to run game on onboard graphics and it runs better than GPU right now but m having similar problems GPU response time (Intel HD graphics) is 12-18ms so m getting little less fps 80 idk it is happening since 2 days and m really annoyed
