Hi All,   I have to work on my friend's Medion Erazer Engineer P10. Surprisingly there are 2 stickers on the back: first one says MD 34830 and MSN 10024811, nothing else. The other one says the product name, model name MT39, type name MED MT 8357N, ML-110000, MSN 10024651 and MD35262. That's two product code which is confusing but he second one seems the right one.  Worked for two years (about) fine and last October (2025) problems started.  Freezing, BSODs and then system repairing boot loop. That's how I got it. As I couldn't get the system out of the loop, I decided to reinstall the OS (Windows 11). Drivers up to date.  Worked fine for two months then the same problem occured.  Memory test ran without problem. GPU seems to work fine. Changed the NvME SSD to a different brand, different size to test. OS reinstalled.  Now, after a month again working fine, I will get it back as crashes again. Sometimes during light-mid gaming with crackling noise or just simply dies on the owner. At the moment it seems like running but with black screen and moving cursor only and no response.    Do you have any ideas?  I'm thinking about the motherboard dying (or a CPU problem), an ageing PSU or - as the latest drivers are from 2022, from Medion's website - incompatibility problem (latest OS (Windows 11 25H2 or even 24H2) contra old motherboard/chipset drivers from the driver package.    It has a Gigabyte B660M DS3H AX, Intel 12th i7-12700F, 16GB DDR4. The motherboard's BIOS version is 103 which is a custom Medion not a factory Gigabyte, which starts with an F. The BIOS date is 12/26/2022 which is - I think - the latest one. The video card is a Zotac GeForce RTX 3060 8GB, the original NvME was an 1 TB Phison, and the PSU is a 650W InWin BE B65E.   Thanks in advance ... Meer weergeven
