While i was gaming, my screen went black but the pc was still working (graphics card fan was running faster). I could only shut down my pc from the PSU(shutdown/reset button didnt work). After that i got into safe mode and eveything was fine. I tried normal mode again and it bugged 1 min after I logged in windows 8.1. I removed my graphics card, ram (one at a time), HDD, cd driver(same thing happened each time). I run diagnostics on cpu, ram and HDD but no errors. I tried to clean install windows 7 but the same thing happened after I formated the HDD. My friend installed and logged perfectly into windows 7.Again, at my pc after 1 min in normal mode happens the same thing (safe mode works fine). I can also boot slax 7 from a live-usb.
motherboard: MSI 880GMA-E45
cpu: AMD phenom 965 x4 black edition @3.4Gh
gpu: Gainward 450 GTS
PSU: TR2 RX-550

please help me...
