Hi Renium No, the original slots 1 and 2 with the operating system on and which have been configured as RAID 0 have the original 512Gb drives on. I only changed slots 3 and 4 and installed 2Tb Samsung Evo 970 drives. I finally managed to get hold of somebody in Dell and they saw the problem (via remote assistance), ran a few tests and confirmed that it appeared the board containing drives 3 and 4 was faulty. It was either this board all the motherboard which was at fault. They arranged for an engineer to visits to swap at the board and since then problem has not occurred again. Therefore, it appears that the problem has been sorted out and I have reinstalled everything back on the new Dell PC. The only issue now is to work out why Samsung magician does not report both drives correctly. It shows one drive as an NVME drive and displays its health and temperature etc, but the other drive it does not, it just states that the drive is a Samsung SSD 970 with unknown written next to it. This is the same as what happened previously though so it might be a Samsung thing. I not at all concerned about this though as I have the same issue on my desktop with the magician software not reporting the Samsung M.2 drive correctly (not displaying health and temperature) and just saying it is not supported, which is of course silly because it is a Samsung drive. Hopefully there will be no more problems with this PC and I have a very clean Windows installation.... However, I am getting the Alienware Command Centre (AWCC) crashing daily in reliability history and event viewer, but again this is not a problem it is just something wrong with the software and was probably happening on everybody's machine (it has done it on every build I have done on the Dell machine - there have been about three builds in addition to the original build). Regards. Matt
Dear all I have recently received the above laptop. I am however finding it fairly unreliable. I have found four or five times that one of the NVMe drives fails to mount correctly in Windows and brings down Windows completely. This originally happened when I was initially trying to transfer some data to the SSD over the network. Daily, the AWCC and Killer DBWM are stopping working, I am wondering if this is linked? I did swap out the original 512GB SSDs for 2TB Samsung Evo 970 drives and there is of course the chance that one of these drives is playing up although I would have thought that if an SSD was faulty Crystal Disc info would report some errors etc. Does anyone have any ideas? By the way, I think it is always the D drive which is playing up. I have contracted supoort, they put the phone down on me? I will use the Whatsapp support during their working hours. I am just wondering if anyone else has had a similar issue with their Alienware? Many thanks for any comments or suggestions. Matt
