Format preinstalled vista laptop to XP (Downgrade)

I used vista for some times, and I notice its explorer always hang. I have to restart explorer at task manager, and results in some icon missing in taskbar beside clock.

So, I tried reformat my Dell Inspiron 1427 from Vista to XP. To my surprice, when I put in XP CD and boot it at BIOS, it give me blue screen (BSOD). I try to find solution from everywhere. Finally, I found out where my problem is.

My SATA hard disk connect type is ACHI, which is not supported by XP. The XP CD I have just support ATA type. ACHI is newer so it is faster, and I found out that the driver can be installed in XP. So, I decided to change SATA type at BIOS from ACHI to ATA. Finally, no BSOD shows and I managed to format into XP.

I have the driver CD provided when I bought my laptop. And, I am surprise again when the driver mostly not compatible with XP. I try google search and found nothing. I think DELL does not create any XP driver for newer laptop. So, I have to format back become Vista.

Nvidia Geforce 9300M GS latest driver

Last post I told that I bought a new laptop that is Dell Inspiron 1427.

Just now I download the latest driver of Ndivia Geforce 9M driver that is 186.03.


I test it on my laptop although it says need confirm with Dell whether is supported driver. The result is it installed without any problem. In fact, I try play Tomb Raider Underworld which is a quite high demanding game. It really increase fps when I play the game, the different is really visible. I can now enjoy smoother game play.

My hostel internet speed

Many students always saying that the hostel I am staying at now has terribly slow internet. I say yes, because I feel the pain too. School limit bandwidth per house and block lots of things.

But, I change my mind after I update my Adobe Reader, which is educational things. Know what, I get download whole 27.6MB file in less than 15 seconds. I measure my bandwidth with cfosspeed, which is a bandwidth controller and optimizer software. It will measure download and upload speed precisely.

Below is the proof. See the orange bar is download speed. 1.9Mbps !! It can get to 2.2Mbps.

I don't know how university get such fast internet. Streamyx only provide highest 4M package, which in real speed only maximum 400-500kbps. I think university paralleling streamyx packages.

The fast internet speed should give us quite fast speed. I think got hacker hack bandwidth so he can enjoy fast speed alone, downloading things, causing others to get very very slow internet speed. Please.... teach me also XD.
