Here are some of the tips I want to share. If they are very few, dont worry, I will definitely update them.
1. DVD drive related (tray opening, slow read, not recognizing DVD, etc.)
I used to have DVD tray opening problem. First, the button on the drive stopped to work, next the eject option from right click, even the small hole under the tray did not work for me. After several attempts, I could not. Finally, I tried nero (not to burn, just if it can open the tray). First attempt, it could not, but with the second attempt, it opened, thank god. From then onwards, I have been keeping a DVD inside the drive all the time. If something is inside, it will definitely open.
The DVD drive definitely, as the time goes on, will become slow. The reason is the accumulation of dust on the laser inside the drive. For me, it started like, slow copying from dvd, unable to play directly from dvd, not at all able to recognize the dvd (displaying CD drive instead of DVD on inserting a DVD), and even if it recognizes the DVD, it shows no data in the DVD even though it is full. I tried to clean it with lens cleaning DVD and then with a tissue attached to the DVD. I dont know which one worked, but now it is reading fine. I didnt try writing (burning) yet.
2. Small round battery in the motherboard.
Long back, it used to be like while I was watching a movie via DVD, the systems gets hanged in the middle of the movie and a strange screen appears with a sound. You cannot proceed except for power-off. Later, I found that it could be the battery (small round battery on the motherboard) issue. I replaced it with a new one. After that, no more that problem.
3. Blank screen, etc.
Some time ago, I was trying to start the system. It tried to start, but it could not, and displays a blank screen (the SMPS gets start and the CPU makes sound normally, blinking the light). I opened the case and watched the inner things. I checked the connections from the SMPS to various parts and I found that the plug connecting to the hard drive from SMPS is a bit loose. I removed and replugged it. To my surprise, this fixed the problem and no more blank screen.
This is related to Security Shield rogue virus/malware/spyware. One day, my system got attacked by this virus. The source is may be browsing some site (I am not sure white site). I googled a lot for removal of this virus. All I can see that this is a rogue virus and you need to have some antispyware/antimalware to remove the virus. To my knowledge, every antimalware software will check only for threats and they do not delete the virus because with the trial or free versions. You need to purchase the license, and so I could not go for that antispyware choice. I asked for one of my friend's assistance and tried to help me via teamviewer. He too searched for removal on the net and viewed some videos regarding this virus in youtube.
Finally what he did was finding the virus exe file. Manually tried to locate the virus exe file through Find option. It showed many exe files. After search is over, sorted the results with date. The trick is that the virus exe file is itself the newest exe file to the system because we tried to remove the virus as soon as we are aware of the attack. Make sure you are dealing with the virus exe file and nothing else. The name will be a random name. He renamed the exe file with another name. He tried to delete the file, but it refused. We rebooted the system and again used Find to locate the virus exe file. After Find is over, we again sorted the results with date. Obviously, again the virus exe file with the name we set was first again. This time we tried to delete it and it got deleted. The annoying fake virus alerts were gone. I think we did it, but I am not sure of any residual registry changes that the virus might have made. But we got rid of the Security Shield fake virus scan alerts. My suggestion is that to do this process in safe mode so that the virus does not try to block you from finding, renaming, and deleting it. I hope this will be helpful.
