Hello,
Recently I’ve came back from vacation and turned on my pc. Every thing went slow, it’s extremely slow. I’ve not used my pc in the last 20 days. The only thing I’ve did after coming back is installing Windows 8.1 Update 1 from the control panel. It asked me for a restart and after that, my computer didn’t turn on. I’ve thought it may be some thing to do with hard disk, but I can access Mavericks and Ubuntu just fine, it’s only the windows that didn’t work.
I’ve opened windows in safe mode and ran the chkdsk utility. To my surprise, there are no problems on the disk. I had to force close any programs using the task manager. There I noticed that the disk usage was 100% and there are no programs except the Command Prompt open. I closed it too and still the disk usage was 100%, I then opened Resource Monitor to find that it was svchost.exe running under system and in brackets, there is “Superfetch”. I went into services and disabled superfetch and suddenly the disk usage dropped to 4-8%. Then I did a small searching and found that Superfetch is a service that enhances the speed of the harddisk data transfer rate. It ran well for two days, then another problem started.
Whenever I opened MS Word, the system got a BSOD and restarted automatically. I thought it maybe due to some spyware or malware and did thorough scans with McAfee, AVG, Avast and also Windows Defender. Still no luck. I installed MS Office again and again the same problem occurred. I thought I should restart and reinstall, but after rebooting, again it was terribly slow, I had waited for 12 minutes to get to the start screen. Then I rebooted into safe mode and from CMD, I ran some commands which I’ve found on the internet searches, I don’t even know what are they, but later it messed with my custom bootloader and even mavericks and ubuntu can’t boot now. Those commands formatted the boot partition I was using for hackintosh.
The only thing left for me is to completely reformat my PC. I also inspected my harddrive with the DiskUtility tool and it said it is in full health. I’m currently posting this while booting in the live cd of ubuntu, taking backups.
Does anybody got this problem before? If so are there any other steps I can take to rescue my system?
Thanks in advance.
