A BSoD randomly appears. The problem began a month after I got the PC, after many attempts of troubleshooting the error (replaced SATA cables, resintalled Windows, Update SSD Firmware, alternate SATA ports, cheked everything is well conected, tested RAM with MEMTEST86) I disabled Intel's Link Power Management because i checked the SSD SMART Data and noticed 22 unexpected power losses, and indeed the BSoD stopped for a couple of weeks but it has come back. I've checked again the SMART Data and noticed that the number of power losses has not increased. It also has a generic 500WPSU, a HDRADEON 6450 and a WD250GB from my previous PC (which passes Wester digital diagnostic though it shows bad sector when tested with different software, i use it only for storage, it has 100MB reserved partition because i forgot to disconnect it the first time I installed Windows7) I wonder if my crappy PSU is supplying unstable voltage and that’s the source of the problem...I dont have a tester so couldnt check that out. I attached all the information I could gather. Thanks for your help.
