Hello everyone. Thanks in advance for all your help. I will explain what happened to my system.
My system consists on the following specs:
-PSU: Gigabyte G750H
-HDD: 1 TB Seagate 7200 RPM
-MB : Z390 Gigabyte Aorus Master
-CPU : Intel 9700k
-CPU cooler: Cooler Master Hyper 212 TURBO LED
- RAM: 2x8 GB DDR4 3600 C18 Corsair Vengeance RGB PRO
- GPU: Asus RTX 2060 STRIX OC
My rig was running perfectly with XMP Enabled until a day the mouse started to move really slowly on the desktop, also when watching youtube videos the sound was weird like it was in slow motion. I could see on task manager that GPU usage ramped up to 100% when doing simple tasks like opening archives or google chrome.Also all the animations beginning from the login to user seemed like they were in slow motion or like a big HD picture being downloaded/or like when cinebench is run. All these symptoms led to no video signal or eventually a crash. After restarting everything seemed fine until all these symptoms happened again randomly. Eventually the PC was unbootable with XMP enabled, so i disabled it and the PC run fin for about 20 days until yesterday. Yesterday all the symptoms came back with XMP disabled and the PC crashed when trying to boot all it could do was go until the AORUS logo then it would freeze (I know this because keyboard would shut down and CAPS KEY LIGHT would not blink) and also in the monitor it showed no signal. So I removed the GPU and windows booted fine with the iGPU and even installed its drivers. The system runs fine like that. I uninstalled NVIDIA drivers with DDU and then tried to install the drivers again but about 1 minute and 30 seconds after beginning installation monitor goes no signal and computer freezes not even responds to keyboard commands. Here is the list that things i have tried:
Creating a partition and installing new windows 10 on it and the problem persists
Trying to install different versions of Nvidia Drivers
Installed a Radeon HD 7850, drivers installed but after reboot the instability persists but on a minor extent: I explain: When opening AMD settings and clicking the settings system crashes, youtube videos sound is only a bit slowed. (The 7850 comes from a system that works flawlessly)
Changed position of RAM to A1 B1 then to A2 B2
Updated the MB BIOS to last version
Used Bios Optimized Settings
Changing the 2060 to lower PCI-E Slots
Making sure that power supply cables are correctly attached
I have also tried to put the 2060 on the flawless system and it runs perfectly fine.
Things that i havent tried yet because of lack of parts are:
-Changing CPU
-Changing MB
-Changing RAM kit
I hope all these information is useful for someone to try to figure it out. Once again thanks a lot in advance. I will keep attention on this post.
