My laptop should have 2*256MB but shows only 448 or 2*192! Can this problem be the source of heavy fan noise?

some laptops share the total ram with the video memory so maybe your laptop total has 512 ram but now is 448 because it share the other memory with the video card. and i don't think that the fan noise is related with this. hope will be useful, try  to enter to the configuration menu when the laptop is starting and look for the fact that i told you

I would just say one of the two 256MB modules is defective. Buy a new one with the same timing, it can be also a 512MB module.

Those are memory addresses. that means your RAM is bad most likely. 90% i would say

Most laptops have a low hum to them, which is caused by the high speed fans running in them to cool them off.  As long as the computer is running normally, it probably isn't a big deal.  Just as a side note though, sometimes hard drives begin to hum as they go bad.

Easy money  you just have 3 connectors, hd, cd, floppy, they connecy just 1 way. just look for the square one, rectagle and the little one for power(floppy). dont forgrt to connect the fans(2). if you have any problem just go to compaq web site , there are pic, to make it easy . good luck!!!!! ohhhhhh  if you add it something make sure  you connect it to slave

I'd start by looking at the fan and giving it a clean if its necessary.  If you've changed memory sticks, then they could be defective - there's always the option of a virus infection as well

Make sure you didn't connect the HDD converter upside down.  This can cause your Motherboard to go bad if you get this wrong.  Check also the power cable is connected.  I saw that it needed a 4 pin molex plug for power.  The converters can sometimes be connected upside down and very risky to do.  Any particular reasons to be doing this?  If its for extra space, it's not worth it.  Laptop HDD usually run at 5400 rpms or slower and it would just slow down your computer.  I say stick with regular HDDs unless you need the small space.

You might need more RAM

if you are using windows XP do this\nRight click on my computer --> proprieties --> advanced --> performance(setting)-->choose adjust for best performance\n\nthe go to advance -->virtual memory(change)-->\nallocate the paging file in the partition that dose not containing your operating system and it should equal 1.5*ram size , in your case 256*1.5 ... and choose no paging file in your OS partition

***Many lame answers*** 2 * 512 MB and I GB are same performance wise. However the 2 * 512 takes up two slots and may make it costlier if you plan to upgrade your laptop to 2 GB. In the first case you may have to throw both the existing memory cards and add two new 1 GB. In the other configuration you can by oly one new 1 GB card and upgrade to 2 GB. Or even you can  buy one 512 to upgrade to 1.5 GB. If I were you I will go with 1 * 1GB.

Depends on what kind of AGP you have? 64MB , 128MB or 256MB? you need 128MB min.

You can add/replace larger capacity sticks up to the total capacity that the computer will handle,.i.e.three 128MB sticks=384MB,three 256 sticks=768MB,one 512MB and two 256MB sticks=1024MB,etc.

add more RAM. that or you can open it up and mess with the jumpers or switches. Doing that will cause the processor to become hotter and it may overheat, ruining you notebook.

You need to buy more/bigger dimms for your computer. If you go to the store and tell them you need more ram they should be able to show you what it is. You may want help putting it in so see if they can help you.

i will have to suggest a 120GB hd drive with a 7200rpm all hd drives take about the same power i know this since i upgrade laptop and do custom PCS for people it might be 2 watts more then hat u have but it is worth it in the long run to get an hd drive that runs 7200rpms i speak from experience trye looking at this like for a hd  drive they have good prices

in case of heating up you should hear the fan spinning much faster, long before the laptop is shutting down - do you? it's pretty noisy. If you don't hear that, you should check the fan. Maybe you have a hardware test program delivered with your PC (e.g. Dell laptops have such a test program).\n\nFurther on, check the airflow channel from intake to exhaust in the laptop and remove all the dust in it, this will improve the cooling behaviour remarkable.

Check the BIOS, maybe 128MB is used as Video RAM.  If that's the case, you are really OK.  But you might be looking at getting more RAM.   Visit http://www.coastmemory.com and look up your system. \n\nGood luck
