Windows won't start when matching ram pairs correctly inserted
Hello, I have tried to install new 2 new 512Mb ram modules in the matching black slots as should be but Windows won't boot after that, presenting a black screen with various options to reboot in safe mode or command prompt etc.
However if I put the ram in unmatched blue and black slots Windows does boot successfully. I could leave it like this but then I won't be able to add 2 further ram modules.
The seller of the ram, Funky Giraffe, has suggested that I upgrade the Bios which I have done from 786B2 v1.11 to v2.22. This has not solved the problem. Are there any later versions I should upgrade to or any other solutions you may have?

You should not change this. Laptops have small video chips and often depend on "shared" memory to achieve good performance without overheating. Basically, the video processor borrows some of your installed RAM memory. Also, your laptop may have been supplied to you with less total RAM memory than the maximum and you can add more memory. In Windows, click on Start then right-click on Computer and select Properties. In the Properties window you can read how much total memory is installed. 2GB (2048MB) is a desrirable amount for Windows XP. Windows Vista and Windows 7 can benefit by having total 4GB of RAM memory. Check your Sony user manual for instructions on adding more memory. Basically, you turn off the laptop, remove the battery pack and unscrew a small cover on the bottom of the laptop to access the memory slots. Usually, there are 2 slots here. Ideally, you should install a matched pair of memory modules (a "kit") for peak performance. However, quantity of memory is more important than having matched modules, so if one slot is occupied and the other slot is empty you may simply buy one more module and install it in the empty slot.
This motherboard uses inter-leaved RAM and RAM needs to be installed in pairs. Check the BIOS RAM settings. Try and use the same make of RAM. One of the RAM modules may be faulty. Try inserting the RAM module that was in slot 3 to slot 1
The RAM modules fit into slots on the motherboard and held in place with clips at the ends of the RAM module.
To remove the RAM module, push these clips to down and the RAM will pop up out of the memory slot.
When you insert the new RAM module/s, place the module in the memory slot, it will only fit in one direction, the RAM module have a notch on the edge where if fits into the memory slot.
Press the RAM module firmly into the slot until the clips pop up and locks the RAM module in place then check the clips are firmly in place.
I recommend you install DDR RAM PC3200 in pairs as per the manual.

No. Just make sure that you two RAM modules have the same specifications (speed, clock).
If you don't know about that, then simply insert both RAM modules and start your computer. If Windows loads, then right click on MyComputer and go to properties. If it shows 1.5GB then you are OK.
If the computer fails to start or you hear multiple beeps it means that they are incompatible.
Replace the 512 module and insert the new one and try again.
Always remember to turn off the power and unplug the cable from the power supply before replacing RAM modules.
Each memory slot can hold DDR PC2700, DDR PC3200 with a maximum of 1GB per slot. Make sure you have not added PC2100 RAM, and try adding a matched pair.
If you have the correct RAM type and spped, then try taking out all RAM modules and reseating them again, as it appears that one may not be slotted correctly. Be sure not to touch any of the Gold leads with your fingers, and of course make sure the power is off, the plug is removed, and then press the power button for 10 secs. to drain and charge in the board before proceeding.
try look the ram module pins support, if any pin broken, or defective, to correct this you need a small tool to put it back on place. (only with power off and battery off). if some pins has not the right place, the computer dont boot.
The computer is not getting pass the POST (power on self test) and therefore the hard disk information doesn't appear and the computer won't boot up.
The problem is with your RAM modules, your motherboard uses interleaved memory, it requires two identical RAM modules (a pair of RAM modules) to be inserted into the motherboard memory slots. These slots are color coded and the RAM modules MUST be inserted into the RAM slots with the same color.
