Hi Kelvin. I'm Greg, an installation specialist, 10 year Windows MVP, and Volunteer Guardian Moderator here to help you.

Test the RAM overnight to stress it with the best bootable test memtest86, following these steps which test both the sticks and the slots:

Run Crucial System Scanner to check the RAM is properly spec'd and configured, what upgrade options exist for first quality RAM:

Go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done:

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files, and also Step 16 to test a new Local Admin account. Then continue
with the other steps to go over your install most thoroughly.

Update your drivers and BIOS/UEFI firmware from PC or motherboard maker's Support Downloads web page, using the full model number, Serial Number or Dell Service Tag on sticker. Compare the latest drivers available for download with the ones presently installed
in Device Manager reached by right clicking the Start Menu. Make sure you have the latest BIOS or UEFI firmware, Chipset, Display (Video), Sound, USB3, Bluetooth, Network and all other drivers, or else download and install the latest now.

Updating drivers from the Device Manager or Windows Update is rarely enough. The most basic thing we need to learn to maintain a PC is keep the latest manufacturer's drivers installed from their Support Downloads web page.

If nothing else works then do a Repair Install, by installing Media Creation Tool and then choosing to Upgrade Now. This reinstalls Windows while keeping files, programs and most settings in place, and is also the most stable method to advance to the latest
version.

If you want you can wait a few more days for the new version to be released into Media Creation Tool which will do the Repair Install while bringing you up to the latest version by the most stable method. Watch for the MCT to change the version listed at top
here:

I hope this helps. Feel free to ask back any questions and keep me posted. If you will wait to choose if I solved your problem, I will keep working with you until it's resolved.

Desktop Window Manager: extremely high RAM usage

After a recent Windows 10 update (presumably the anniversary update) I have noticed that Desktop Window Manager will start to use an extremely high amount of RAM while running applications that previously I had no issue with.

The situation I am experiencing this is when I am playing a game (Football Manager 2016) on one monitor while streaming video via Chrome or IE on a second monitor. Previously, I have done this with no issue, and could have the PC in this state for hours
on end with no problem.

However, since the update I have been getting the following error message after Football Manager 2016 for a while:





It seems that it may be Desktop Window Manager that is hogging excessive amounts of memory. For example:





Is there a known issue with Desktop Window Manager? I have contacted the developers of Football Manager 2016 in the first instance and they suggested this looks like a memory leak in Desktop Window Manager.
