Why suddenly videos on my HDD are running choppy?

Im having good configuration PC. All videos including 720p & 1080p were all running smoothly on my PC. These are not streaming videos. I use MPC-HC & VLC.

Couple of days before when I was online, I had updation alert for Java, so I went for it. During installation, it again alerted me that Java is for Win 8 & above but I can go ahead with it. Along with that Java package, chromium (similar to chrome browser) was installed.

After that, my PC & internet slowed down. So I tried to uninstall chromium. But each time I reboot, I was seeing chromium asking me something at startup. My default search engines in chrome & firefox too changed (maybe to "palkan" or something similar). My offline videos (low & high definition) were started running choppy. Noted that audio in those video files was very fine. Tried playing MP3s but they were too fine. Just videos I was playing on MPC-HC & VLC was choppy. Higher the video file size & definition, the more choppier they were. Windows startup was very normal & fast as it was before. But as I plugin internet modem, windows would slow down. But videos are choppy even if I did or not plugin my modem. Somehow managed to forcefully uninstalling of chromium using "uninstaller" & also deleted all related files in "program files" & desktop icon. But that did not work for slower videos.

Update:

So after all that mess, I revert back to a restore point (created about a week back) using system restore. But that too did not solve my problem of choppy video & slower windows & internet.

Anybody please help me out. Im Really scared now. I have a huge data. Could that error be related to my video card or graphics? Please tell me in detail how can I diagnose this?

    Where did the java alert come from? If you did not download it directly from Oracle (or whomever you get Java from) I'd be very wary of the the Java download. If your browser homepages or search engines changed, that is a bad sign. Try safe mode with networking, and run some malware scanners (malwarebytes or a reputable antivirus scan like avira, avg, mcafee or symantec or run more than one). This sounds like a website prompted you to install "Java" and you did and it was not really Java. Also, very, very few sites use Java anymore. Many people have not installed it in years and most security companies and browser manufacturers recommend against it (and against Flash as well).
