Predator Helios 500 - Lag spikes in games and sometimes desktop applications
Hi!
I have gotten Predator 500 about a month ago. It has been working perfectly well, until several days ago. After that I have started getting some occasional 2-3 seconds long lag spikes (about every 10-15 min) in some games (such as StarCraft 2, Tomb Raider 2015). Before those games were running perfectly well on ultra settings without any problem with stable 60+ or 120+ FPS depending on the very demanding graphics settings. Both games are installed on HDD, however, there was no problem with them prior to this time (for a month!!!). Other game Rainbow 6 Siege is installed on SSD and does not seem to have any problems (strangely enough). Sometimes when I use my usual applications (e.g. Discord or browser), they also lag out for 2-3 seconds. It is worth noting that a day before issues started I updated my Windows and graphics drivers.
Attempted solutions: reinstall graphics driver, turn off Shadowplay overlay, try fullscreen AND windowed settings of games, repair game, restart computer, check for new Windows updates, turn off unnecessary startup services, scan for viruses. Neither of the following things has helped.
I did check both temperature and whether any other processes were taking up CPU/GPU/disk. It does not appear to be the case and for example StarCraft 2 does not eat a lot of CPU, GPU or memory and leaves plenty of space. There are no other processes that eat any significant amount of CPU/GPU (not more than 5% combined). Temperatures are good and don't come close to critical values. Is there any other possible solution beside reinstalling Windows (which takes about a day, including reinstalling of all updates + files, so I try to leave it for the last if possible)?
Any advice is appreciated. Thanks!
