Try one only 256 it should work now. You cannot use a 256 with a 64 it just will not work it is physically impossible. I know with some of those older models and Im picking yours is because you mention you were using 2x64. What you should have done was to buy two x 128 I am possitive your board can only handle 256mb of ram. Try the one only and if it works use that I dont think two of them will work not on that board?? Let me know ok. You might wanna clean your machine out with a software like this and its 30 days trial but has all features till it expires: http://www.tuneup.com. else if you dont want to take my advice on your laptop you can always go here: http://www.compaq.com

What you are seeing is a "blink code". Similar to something like a digital SOS message, your laptop is built to flash certain LED lights a specific number times to indicate a hardware problem.

According to Compaq's table of blink codes, the Caps Lock LED light blinking five times consecutively means you have a system board failure. If your laptop is still under warranty, I would contact the company immediately and have it shipped out to be serviced. Otherwise, you will need to either pay Compaq or another third-party repair shop to fix or, more likely, replace the system board.
