BSODs overnight mainly in ntoskrnl.exe

I'm getting BSODs almost every night. Attached is the result of DM Log Collector. Would appreciate some help.

Hmm, run MemTest86+, sfc /scannow and chkdsk /r.
Install the latest updates from Windows Update.

Do the exact same steps for chkdsk /r but instead of typing in sfc /scannow type chkdsk /r.
SFC /SCANNOW Command - System File Checker
RAM - Test with Memtest86+

I'll start with running MemTest86+ overnight. Thanks for your support.

No problem.

An update: both Windows Memory Test and memtest86+ revealed memory errors. I took a chance a purchased new memory even though the problem could be the motherboard etc. The memory was quote expensive now that it's basically legacy memory (DDR2).

When I went to replace the 4 x 2GB RAM sticks, I noticed that one set was generic and the other set was Corsair and the same model of RAM I just bought. So I replaced the generic RAM sticks with new Corsair ones and re-ran memtest86+ and it still found errors. I replaced the old Corsair RAM sticks with new Corsair RAM sticks and was able to survive a memtest86+ test.

The system is now running Windows 10 and we'll see if any more BSODs occur. I'm disappointed that I had to replace the old original Corsair RAM with exactly the same RAM, just new!

Well they were failing very hard as even Windows Memory Test revealed errors. I guarantee that there will be no more BSODs.
