Windows 10: BSOD Crashes after installing new CPU

Hello, I recently bought a new cpu a Ryzen 5 3600, but after installing it my pc started to blue screen with the IRQL_NOT_LESS_OR_EQUAL or KERNEL_SECURITY_CHECK_FAILURE. They are not consistent with the errors. I can go on playing games for a while but when I do something productive like randomly browsing on the internet or working, sometimes my PC would bluescreen out of nowhere and it is very annoyingI've tried:Already reset my pc with a new installation of WindowsTook ram out and tried one stick and vice versa on the two sticks of ramReset defaults on the BIOSThe specs are SU: 550W Cors

PC reboots (no BSOD) on CPU stress

Hi fellow TPU members,

not too long ago, the box my gf's PC was transported in gave way on the stairs. Yes, you got it right, that sent a PC tumbling down a flight of steps alright.

Stuff broke. Also, stuff remained intact somehow.

I bought her a new case, new CPU cooler and we removed the floppy drive, so far so good. But the PC started crashing for no apparent reason, without a BSOD.

I tested:

• Memtest86+, left overnight, 0 errors
• Scanned the HDD for errors, nothing there
• Left FurMark burning up the GFX card and drawing some power, no problems there
• Ran Ubuntu from a Live CD doing nothing special, didn't crash
• Ran OCCT, Linpack, Prime95, all 3 caused reboots within minutes
• Oh, and I disabled "Restart on error" so I'm sure it's not a BSOD.

Now, I can still try and test something CPU intensive on Ubuntu, but my guess is the CPU didn't survive.
Before I do anything drastic like whippin' out the magic wallet and get her a new AMD quad, is there anything I didn't see?
I'm guessing the motherboard could be borkered as well, but can I check that other than replacing the CPU with a working one?
Any suggestions on which proggies I can use from an Ubuntu Live CD to stress the CPU?

 

Flickering screen at startup, crashes, and BSOD after instaling new GPU

SO the Logs showed no errors at all during them times? They will be listed with a RED X Circle?????

Well if you just installed Windows 7 then make sure you have all your mobo drivers (chipset and all that stuff) from the mono vendor website, Then make sure you have your .net installed and updated as well as Direct X...THEN INSTALL THE AMD CATS!

Here are some that are close to the BSOD crash time but i dont think they have to do anything with the BSOD.
