My computer has some slowness issue that I can't figure out. It happens everyday, and I can't really pinpoint what causes it or when exactly it happens.
- Motherboard: MSI 7370 PC ProMSI Z370 PC Pro
- RAM: 32 GB DDR4
- Processor: Intel i5-8600K (not overclocked)
- Windows 7 Pro
- Dual Graphics cards: MSI GeForce GT 710 & MSI GeForce GT 730 - using the same driver
- Three monitors - All the same: Dell S2415H (one connected via VGA, the other two via HDMI)
Now, Intel's 8th gen processors do not "support" Windows 7, therefore the onboard graphics do not work at all because there is no driver available, so I have to use the two graphics cards. However, Windows 7 runs just fine otherwise.
Also, I am using an internal SSD drive to accelerate my C drive (HDD) with Intel Rapid Storage Technology.
Thunderbird and Waterfox files, profiles and applications are kept on an internal NVM disk - as fast as you can possibly get.
The slowness happens, from what I can tell, after I leave my screensaver on overnight - so I'm suspecting it is on account of system idling. Slowness consists of certain programs not reacting instantly - there are lags when I type, lags when I click the mouse, if I run the Nox Android Emulator, it is slow to react and sometimes freezes for a second or two before reacting.
I can fix it all by rebooting. Sometimes if I close programs (doesn't matter which ones), one of them will "release" the lag and everything will go back to normal speeds.
I've defragmented everything. The machine is not consuming much RAM or CPU - the meters never run past half the total available amount. Crystal Disk Info reports a "good" health status for all my disks.
The only thing left for me to do is a memtest.
Any other clues here?
