What's wrong with my computer??

Haiz...today from evening..after i installed msn plus..

my computer the whole screen suddenly turned into a blue screen with some words written there is an error with the new software or hardware..something like tat..not really know wat happen to my computer..anyone can tell me??

is it virus??

i press everything that i can..but nothing happen..finally i have to switch off the main switch of the computer..

After restart, my computer seems to be ok already..but..i left it open to download my drama..after i came back from dinner...I saw that BLUE SCREEN again !!!

what the....zzzz.......haizz..
well, alright i have to restart com again..who knows...when bee came to my room just now..to save some software..my com get into the same situation again..

then the 4th time coming again after i reopen my com..

this time no more BLUE SCREEN...the screen does not appear anything at all !!!

then...u know wat i did??

erm..i became my own computer technician.. -.-

As my computer is Dell computer, last time for once i called Dell company as my com can't start at all.. The technician did not send anyone to assist me instead he asked me to solve the thing myself...

In the beginning, he asked me to open the switch and see carefully above the power button..Which light is turned on..i can't really remember whether is light num 2 and num 4 is on or num 2 and num 3..

Then, the technician taught me how to open the CPU cover and take out the RAM card slowly then fix it back..After fixed back the wires to its original condition, the computer can start already..

Tat technician told me that was because the System sometimes can't detect the RAM..

After dunno how long...that's today..i tried back the same method...i saw the light num 2 and 4 were on..but i really can't recall izit the same situation..

I just tried to remove the wires and cover of CPU..then take out the RAM slowly and fixed it back..

haha..luckily i still able to turn on my computer..

Considered repaired successfully?? i don't know the answer...erm...

I just can pray hard and hope that my computer got no problem..

Hope so that blue screen won't appear again...

Please.....zz...

I already deleted my MSN plus..cause i scare that blue screen is caused by the msn plus..

hopefully my assumption is right..

Any ideas y got tat blue screen??

let me show u the blue screen pic..

here is it..
