Drivers do not wear out but a new game could trigger issues. The tell here is the browser and the SFC fail.
That points to hardware or malware (trojan, virus, spy...)
I don't see the PSU or any mention of cleaning, fresh heatsink work or the usual hardware maintenance. Tell more about the PSU and the last time the canned air was used. Try it with the cover off.
I also don't read any mention of the Intel RST. https://forums.lenovo.com/t5/Windows-7-Discussion/Win-Update-fails-amp-sfc-scannow-errors-on-new-win7-x64-ult/td-p/520753
I currently have a lot of stability issues with my computer.
I got a lot of BSOD, game freeze, even my browser has issues and sometimes cannot find websites.
I also get some dialog about corrupted data and memory which cannot be read.
My first guess was a SSD failure, so I performed a chkdsk and a SMART test, both successfully.
I also did :
- A mem check on my RAM
- Check the hardware heat
- Update of all drivers
- Malware scan
- I tried the "sfc /scannow " command but it failed (memory address problem)
- I check the minidump reports and the issue wasn't always the same. Most of the time a dll is failing...
My config :
OS : Windows 7
CPU : i7-3770
GPU : GTX 770
