Computer became slow recently

0

System Specs:

Windows 8.1 64-bit
Intel Core i7-4700MQ CPU @ 2.40GHz,
8.0GB RAM,
Intel HD Graphics 4600 / NVIDIA Geforce 750M GT

Computer has been recently slow. This includes startup programs, opening files, installing programs, booting, shutting down, and gaming. However, CPU, RAM, and DISK usage is fairly low all the time. I confirmed this through task manager when opening programs. System restores seems to be the only way to solve AND worsen the problem. I have system restored several times and sometimes it would be back to speed, but slow down later. Sometimes it would get worse after system restoring.

I have tried the following that didn't help:

  1. Scanned entire system using Malwarebytes, got rid of some malwares, but they weren't the main issue.
  2. Scanned entire system for viruses using Avast, no viruses detected.
  3. Defragged and cleared up some fragmented files. It didn't fix the slowness though.
  4. Updated all drivers to latest version.
  5. Clean boot (disabled all startups/services)
  6. CCleaner with registry cleaning
  7. Ran chkdsk and sfc /scannow, found one error, but was it was unable to fix it.
  8. TuneUp Utilities & Advanced Systemcare in attempt to speed up computer.
  9. Plugged charging adapter to a different outlet.
  10. As mentioned, I have tried system restoring several times. It was only a temporary fix. I am running out of system restores...

Note that I have tried running in safe-mode with clean boot. It still runs slow.

Any help would be appreciated.

Probably the issue is hardware related. Did you try Safe Mode yet? If you haven't already, check the Event Viewer (eventvwr.msc) for further details. Also, avoid cleaning the registry and "optimizers" such as TuneUp Utilities or Advanced SystemCare.

Drives seems fine. Here are the results. http://puu.sh/bfQQB/53b7ead98b.png For Event Viewer, here's what I got: http://www.mediafire.com/download/3fdid7m50a2o5g2/Event_Logs.rar I have a whole bunch of errors and warnings in administrative events. Not sure if that is the problem. I can't save the administrative events because it gives me "The system cannot find the file specified".

Your computer appears to be a Lenovo laptop, namely an IdeaPad Y410p or Y510p. What BIOS version are you using? I've skimmed through the events, and I noticed many different applications crashing/hanging. Also, there are many events like this: "The speed of processor 7 in group 0 is being limited by system firmware. The processor has been in this reduced performance state for 41905 seconds since the last report." Try running sfc /scannow again. If you get any error message, copy the CBS.log file (which is usually in C:\Windows\Logs\CBS) to the desktop, add it to an archive and upload it. – and31415 – 2014-09-01T10:10:08.537
