I bought my computer less than a year ago. About a month ago, I started noticing the computer slowing down...it was taking longer to load up, and also just opening/running programs.
As the month passed, it got progressively worse. Here's a summary of problems I've experienced since then.
1.) Computer boots up fine to the log-in screen, then when I put in my password, it either stalls at a black screen (I can move my mouse but nothing happens) or takes in excess of 10-20 minutes to load.
2.) IF I am actually able to log into windows, everything is EXTREMELY slow. I'm talking 1-2 minute delays in response time. I'll try to open Firefox, and it will stall and won't open until 2-3 minutes later. Even when I type, it takes a minute or 2 for the text to actually appear on the screen.
3.) I have tried booting up in safe mode, but I still experience the extreme lag/delay.
4.) The computer will try to run a SCANDISK check when I boot up (unless I skip it), but once it gets to Phase 2 it always locks up when it gets to a certain file (I think it was like 189,000 or somewhere around there).
5.) Previously I had tried running adaware (found only cookies) and Avast anti-virus (found nothing).
The computer is pretty much unusable at this point. I thought it might be stalling because it's constantly checking for a program or something, but I've tried uninstalling everything but the bare minimums and still have the same issue. When I go into resource manager, the CPU spikes in usage every few seconds, up to as high as 75% despite not running any programs (just the Windows desktop).
Any solutions or ideas would be GREATLY appreciated. I would really like to avoid reformatting if possible.
