So I just booted up from sleep mode earlier (was in sleep mode for around 5-7hrs) and when I did I seen like square boxed pixels ( I believe they were a green and purple colored pixel boxes), but they were probably about .5cm in size and only covered portions of the lock screen of my Windows 8.1 Pro computer. After I typed in my password and everything the home screen looked fine. Is this something that was an issue with the OS, Sleep mode, GPU, or some other thing?
Also when playing BF4 online, at max settings with res scaling at 100%, I would stay at a solid 60fps, then about 10min into the match I start seeing slight drop in fps, to 55 and bouncing up and down between that at 58 or so fps. While gaming my GPU does get up to 198 deg F at the max...
Specs:
MB: GIGABYTE 970A-DS3P
CPU: AMD 8350
Ram: 8gb Kingston HyperX (1600mhz)
GPU: AMD 7990
HD: WD Blue 1tb 7200rpm
Damn, 93 Celsius? Thats HOT man, It shouldn't exceed more then 75 (well, It can, then the GPU starts to downclock itself due it trying to save itself from burning up) Id take a look at your GPU cooler fan and stuff, Is it a stock Radeon card? or is it made by Asus or someother people?
also, About the weird boxes and stuff, I would think it could possibly be either the monitor, or the cable, Try using a different monitor/cable or both and see if it fixes it. If not, it may be time to get a new GPU...
