I am using Acer Aspire 4530 and I have 4GB of RAM. My computer currently have two operating system, one is Ubuntu 12.04 64 bit LTS and the other one is Windows 7 Ultimate 32 bit. When I just installed Ubuntu on my computer and I only install Google Chrome into my Ubuntu OS, I tried watching a 1080p HD rolling in the deep and Gangnam style videos and I realized there is a little lag when I watch both videos (one at the time). I didn't open any other programs or tabs while watching. When I lock my computer and when I unlock my laptop later, I saw a very weird screen on the desktop which look like the program has been hang and I have to logout and login again just to open the browser. So should I downgrade to 32 bit Ubuntu 12.04 LTS to solve the lag while watching a 1080p HD video? If your answer is yes, may I know is it possible to downgrade without formatting the hard disk?
I can't see that changing from 64-bit Linux to 32-bit would make any difference. If anything I would expect it to reduce performance further. This is a fairly underpowered laptop; what is the performance like in Windows? There is no easy way to downgrade from a 64-bit OS to a 32-bit one without doing a complete reinstallation; a format of the partition would almost certainly be necessary to clear out the 64-bit components.
Thanks for your reply. I understand that 64 bit will requires more RAM than 32 bit so I thought if I downgrade to 32 bit, it will require less RAM for 32 bit and I can use the remaining RAM to watch 1080p video with less lag. Am I right?
I don't think so. Again, what is the performance like in Windows 7?
There are graphic lags when I play games and I always need to end uncessary process in Windows Task Manager to reduce lags. There is no lag when I watch 720p YouTube video and there is lag when I watch it in 1080p without ending uncessary processes. Any idea how much RAM is required to watch a 1080p YouTube video without lag? My brother computer has 8GB RAM, and YouTube automatically let him watch in 720p HD when he play a video.
"There are graphic lags when I play games and I always need to end uncessary process in Windows Task Manager " The keyword in that sentence is "uncessary". If you know the processes are unnecessary, why do you allow them to load in the 1st place? Use MSCONFIG & CCleaner-Slim to reduce the startup apps to an absolute minimum.

Also, your laptop is an older model with older Geforce graphics. You shouldn't expect stellar video performance from it.

Thanks for the advice. May I know does it depends just on the RAM or the graphics also affect high definition video lag?
May I also know whether is it possible for viruses, malwares, Trojan, etc to infect Ubuntu OS? Do you need I should install an antivirus program for Ubuntu OS?
If you experience the same problems in Windows as 64-bit Linux then I see no reason to suppose that downgrading to 32-bit Linux is going to help. I think it is just a question of what your laptop is capable of.
Please answer the question below. May I also know whether is it possible for viruses, malwares, Trojan, etc to infect Ubuntu OS? Do you need I should install an antivirus program for Ubuntu OS?
"is it possible for viruses, malwares, Trojan, etc to infect Ubuntu OS?" Possible but rare.
"Do you need I should install an antivirus program for Ubuntu OS"
Probably not necessary but if it will make feel all warm & fuzzy & less paranoid, go right ahead.
May I know if I install a program called Wine which allow me to run Windows Application will it increase the chance of my computer been infected?
