Hi to all members. I am a newbie at Techspot but have some experience with IT hardware and software. Have been having problems with my PC - first noted file corruption (caused by some hardware fault - not software or malware). Chkdsk revealed bad clusters but later scans showed hard drive 100% in good state. Tested RAM and also found no problems. Physically cleaned PC hardware, checked component seating - found PSU fan damaged and replaced whole PSU. Possibly overheating cooked some other component. I also change IDE cable. Now system is more stable but I am getting random BSODs on shutdown and I probably something is still wrong. My prime suspicion is that the mainboard has a fault................ Attached is system info and dump from latest BSOD on shutdown. Would appreciate some guidance.
