Ok, so I built my PC some time back and for a good while everything was fine. This is probably my fourth homebuild but I'm in no way an expert, just lucky not to have had any problems I guess. Well, recently I was having problems with BSOD's. The symptoms pointed to HDD failure. After running CrystalDiskInfo, it reported that my main HDD was on the way out. I backed up my data, bought a new HDD, did a fresh install of Windows 7 64bit Ultimate and everything appeared normal again. Then I started receiving more BSOD's. The culprit this time was something to do with ntoskrnl.exe and a different driver every time. As I understand it, this isn't too much help in diagnosing the problem.
I tried various things software related including ComboFix, sfc /scannow, chkdsk /f /r. Then I stumbled across DriverScanner in another forum. A free 12 months registration was on offer so I gave that a go and updated all my old drivers. Everything seemed fine after this and I was happy that I had beat the problem! Only I hadn't. Now I'm getting random resets with no BSOD. Event Viewer comes back with Critical Kernel-Power problems., and lots of them.
I've got CPUID running and the only thing that looks suspicious (to me) is CPUTIN running at 80-90deg, AUXTIN showing a max of 127deg, TMPIN3 showing a max of 126deg and TMPIN4 124deg. These last 3 are only max's and are currently at normal sub 40 temps. SpeedFan is showing a CPU temp of 89deg. This may be the cause or just a symptom.
Having read various related threads I see people posting various scan results and reports to aid in diagnosing problems. I'll be perfectly honest here, I have no idea where to start. If I could find somebody with a little patience to walk me through I would be most grateful. Any information you need, please just ask.
