What can I do when the Windows 8 x64 operating system files get flagged as corrupt by sfc even after a complete reformat and reinstall?
I reformatted the computer because I had trouble with WiFi, USB ports, intermittent full system hangs, and SQL Server Management Studio would frequently hang, crash, or both.
Is it possible that sfc is creating false positives? How would I see if that's happening?
Of course, it's possible that the files weren't corrupt before the reformat & rebuild but that shouldn't matter.
The Dell Vostro 3460 is used at work and all of the licenses & install media came through legitimate channels (e.g. MSDN license). I've considered malware but both Trend Micro and Windows Defender (aka MSE) turn up nothing of note. The drivers and BIOS are all up to date.
SpeedFan regularly shows little flames next to all the temperature sensors except Temp1 and Temp2. However, when I disassembled the computer, I didn't see much dust and I removed that which I found. The laptop is positioned on a flat surface and I can feel a breeze from the fan vent on the left side.
To be exact, here are the displayed temperatures right now. The laptop was left on over the weekend and I haven't run any CPU intensive tasks so far since coming back to work.:
- Flame, HD1, 50C
- Flame, Temp1, 51C
- Flame, Temp2, 51C
- Up arrow, Core 0, 47C
- Green checkmark, Core 1, 46C
- Green checkmark, Core 2, 44C
- Green checkmark, Core 3, 47C
Running the short test on the normal HDD comes up clean. When I run the short test on the mSATA SSD, SpeedFan hangs with a status of "in progress...".
I have other computer problems too but I'm reluctant to seek help for them when the OS may be corrupt.
