Britec Tech Support Forum

Hi, I have windows 8.1 pro and I am having problems with windows. Firstly, I wanted to make windows faster so I downloaded tweaking windows repair program to optimise performance and then after a day I had errors on my hard drive. After that I allowed windows to restart my computer to repair the errors and right at the start of scanning and repairing drive C, I got the blue screen of death, error code 'Critical Service Failed'.

I then booted my installation media, clicked repair my computer and successful repaired the errors and then I restored my system before I tried to optimise windows. (Using System Restore) Then I had a problem with google chrome 'Connection not private', so I restored my system to a system image of when windows was in a good state, however, my system is slow and the indexing service is corrupted. I have discovered why the critical service failed because I couldn't install windows by booting up windows and doing a clean installation, I only could only do it from the desktop by running setup.exe.

Since my system came preinstalled with Windows 10 Home, so I should downgrade. But I have another problem. I have installed windows a couple of times and I was unsure if it would make system slow, so I posted a thread about it and was advised to create this thread. See https://briteccomputers.co.uk/forum/showthread.php?tid=2294 for my previous thread. But I have scanned my system for malware and removed, I also used crystal disk to see my ssd's health and it is one percent healthy.

Should I downgrade and do a clean installation of windows 10? will it damage my ssd and make it slow?

Information about my system:
Manufacture: PC Specialist Gaming desktop PC
Model Number: Vanquish Elite 3 Gaming PC
SSD: See attachment
Graphics Card: Nvida Geforce GTX 970
Anything else let me know

Like I said, I installed it by running setup.exe in windows 10 desktop because I couldn't boot my installation media and perform a installation because of the error message bcd is missing some required information and tried to rebuild the bcd using cmd but it didn't work, my system is blocking it somehow ( I think it is the Bios). The windows 8.1 ISO came from media creation tool provided by microsoft.

ok it sounds like you still have some malware on the system or you optimize something wrong in windows.
you said Since my system came preinstalled with Windows 10 Home , so I should downgrade.

ok you can't downgrade what are you going to downgrade to?
you said you download windows 8,1 Iso from Microsoft but how did you get it activated

I did optimise something wrong in windows. How do I fix it? AlsoI put that wrong, Since my system came preinstalled, Can i go back to my original OS, will it damage the ssd. I had a Windows 8.1 Pro key, that is how I activated it.
