as a v3010 user.i would like to tell u that ur current ram is only 4300.if u expect to have faster speed..try get both 5300.however im using 512mbX2 like wat ur going to have soon.512mb 4300 and 512mb 5300.smoother when playing games like CS and cpu load is lower..summary:ok la.
price?get less than rm35.recomend get 2nd hand 512mb ori compaq ram from other forumers.haha.

posible reasons:
1. reinstal drivers.
2. try insert the OS format cd and restart ur lappie..see any changes
3.if none of the above, ur rom is dead.i got a fren whose rom kong after i format her lappie..she went for waranty.

think ur lappie wont have waranty only if u extended it at the 1st place..
gudluck.

wat do u mean by black screen?any blue light indicate when u on ur lappie?if yes, ur mobo is burn due to graphic card failure.if so, u have been gaming too much..u muz be having an amd-based lappie.
