I have windows vista on the computer. Lately, about two days ago, I noticed that my computer doesnt boot up all the way. When I press the power button, the LEDs light up, and I hear the fan. About 5 seconds later, the laptop shuts down and then turns on again, again with no proper boot up, at least I think there is no boot up, I cant see anything on the screen.

I have already tried taking out the battery and the ac cord, holding the power button for 30 seconds to dissipate any static and then just plugged in the power cord. But same thing happens. What should I try next

Try taking one stick of RAM out then booting, if problem re-occurs, then put that stick in and take the other out and try again. If you have extra sticks of compatible RAM to the computer lying around, then just replace them with that and see if it works.

Ill try that. If I have other DDR2 sticks, then can I use those, or do they have to be the exact spec, like replace a PC2 5300 with a PC25300 only, or can I use PC2 6400 or PC2 4200 and so forth.

I ask this because you motherboard mannual will tell you what she can handle. It should say something like: "2 DIMMS support for DDR3 1066/1333 MHz ... " the "1066" is the Lowest she will take while "1333" is the highest. Divide the PC rating by 8 and if it falls within that range then you're good to put it in. I'm not absolutely certain this is your problem, but it is a troubleshooting measure to eliminate RAM being the culprit. I have seen bad RAM do what you have explained.
