It looks like I may have incompatible RAM perhaps... I read somewhere that the light combinations I see is the mobo trying out different ram profiles. This could make sense as every time it eventually posts it tells me to go into the bios and set RAM parameters, sometimes it gets the right frequency, other times it starts with 2133MHz rather than 2400.... I checked the Asus site of working RAM and my model doesn't appear, though several similar models do... The timing matches, I don't know much about RAM - should an untested/unapproved model even with the same timing and frequency be a deal-breaker for the mobo?! Any other ideas?!

Asus Z370-A 2x 4GB Crucial Ballistix DDR4 2400 i5-8600K GT 8800GT 1GB 500W Antec PSU Zalman something-big cooler Kingston SSD I took the PSU and GPU from my ancient computer, installed it all, it ran on first boot and ran windows & games fine. Stood the case up, and it no longer posted, showing a sequence of error lights - CPU red, RAM orange, VGA white... Tinkered with it a bit, now it's all out of the case again, and sometimes posts fine and gets to windows, fully installed, with 1 stick in random slot, GPU or iGPU, complete with random holds of power and MemOK buttons... Now I'm really at a loose end.... Doesn't help I don't really know what the error light sequence means! Thanks,

Drive - Hard drive: This drive was showing 0% fitness when I went into smart on speedfan... I just didn't think a bunk drive would cause the whole system to dive off a cliff, especially as it just had docs/desktop/media/etc and not the system... good learning for me! The system has been on since I posted last time, with no BSOD or issues! I've played a couple of games, watched a movie or two and used it for work: about 20 browser tabs and a few excel docs (It's nice to be back on Windows... I've used a Mac for work for the last few years).

Fixed it myself, and I learnt something new! The failing drive was at fault, replaced it with another, and I've had a stable system for the last 6 hours with no system errors. Great, thanks!

Update - well that didn't solve it. Memtest single pass gave no errors. Could the failing disk cause this? There are quite a few disk errors (bad sectors) in the system log, and I think there could be a correlation of crash to heavy disk access, but it's not cut and dry. Any ideas?

OK in the last hour I checked the dumps and found the problem is specifically ntoskrnl.exe+16bf70, google doesn't help me understand what that actually is... I changed a few things: -Reinstalled the nForce storage controller from Nvidia's site. It says windows 7/Vista but I'll see if that could have been it... -Also i went into BIOS, the memory was automatically running at 667MHz. I even pulled a stick out just to make sure I wasn't wrong about it being DDR2-6400... It was as I expected, so I manually changed the clock speed to 800MHz. The only time i touched the BIOS recently was to change the boot drive when i cloned the OS onto the SSD last week... bizarre! I'll see if it was one of those two things... Maybe I'll do a memtest if it stops again, strange though, I don't think it could have been hardware as the only thing that changed was the software, I've had the system running for the last week just fine... Damn Win10, I shouldn't have touched it! Note- Since I started this post, 80 mins ago, I've not had one BSOD!

@jools here's the 'Standard Dual Channel PCI IDE Controller' driver file options I get: Edit: The other two just have atapi.sys and ataport.sys

@jools Thanks, I didn't have much luck with that... see photo attached, it's not there... I checked the three devices for iastor and they don't have anything similar, all are using atapi.sys @Dennis de Rooij [NL] I get consistently >50fps with Oblivion (remember the top GPU when it was released was 7900 GTX!!), I'm on a pretty low res screen too! Civ 5 the FPS is >100fps... Both games - and the system - worked well enough on the same hardware before Win 10.

I've played both games with no issues on Windows 7. MS suggest my hardware is capable enough for Windows 10.

I get a DPC Watchdog Violation BSOD randomly on my recently upgraded machine. It's a very old desktop i built in 2007 or 2008. I'm only wanting to play Civ 5 and Oblivion... Last used this machine in anger in 2011, I had Windows 7 on it, now I thought that an upgrade to 10 wouldn't be so bad..... I also swapped the boot drive for a second hand Kingston SSDNow 300, it worked fine in Windows 7 while I was waiting for the 10 upgrade to download. I've done a DDU graphics driver reinstall, and checked the chipset drivers also - they dont say compatible with win10 just up to 7 i think..., as well as NICs, Realtek HD Audio, and I do have a cheap wifi PCI card, branded 'Tenda' which I can't find drivers for (it works fine...). I've had the crash with this card disabled in device manager, so thought that would rule it out... Oblivion and Civ run really well, I actually havent had the BSOD while running games. Here's the system specs: AMD X2 5800+ 2.8GHz (no oc) 4GB Crucial Ballistix DDR2-800 EVGA Geforce 8800GT 512MB MSI K9N SLI Platinum with nForce 570 chipset 120GB Kingston SSDNow 300 500GB Samsung (?) 3.5" drive (which has a bunch of bad sectors, it doesnt have any apps on, just movies, documents and music - I'm gonna swap it out as soon as i've fixed this BSOD shit) I have the latest memory dump if that helps? Any other info I need to give here? Edit: Hi, long time lurker here! Thanks for any help!
