My laptop has 2 RAM slots of 1GB capacity each. It came with only 512 MB RAM and one empty RAM slot. I purchased and installed addtional 1GB RAM with the following specifications 1GB Laptop 200pin PC2700 DDR333 SODIMM. After installing the RAM, laptop started correctly and the chip was recognised. But after 5 minutes, the system crashed after a memory allocation failure.
Attempts to restart the laptop resulted in BIOS failure and system hang with a shimmering onscreen display.
I did not try to remove the original RAM chip from its slot, fearing that the computer may not start altogether.
The laptop works fine without the new RAM chip, but not with it. I have rechecked the technical specifications of the chip, these match with those specified by the manufacturer.
Please can someone help resolve the problem? Many thanks in advance for your help.

sounds like a faulty or incompatible stick of ram ... try it with just the new stick ... if it works it means the new stick is not compatible with the old stick ... if it doesn't work it's either the wrong type of ram or faulty

You have incompatibility due to CRC on the chips. They required matched set for it to work correctly. You should be able to run on the single new chip if it is of the correct speed. If faster than the one installed, that is OK, just not slower because that will conflict with the bus speed. PC2700 is fairly slow by todays standards and for most systems up to a year old.

It apears to be a hardware problem, which leaves you with 2 options.
either, it is the memory module, or it is the slot.
The only way to check, would be to put the 1 gig memory module in the slot where the 512 mb one is currently, and see if it boots then, if it works, then it means that the other slot is broken.
If it still does not work, then you need totake the memory module back.
Good luck

I agree with ludwich. your computer is fine as long as it doesn't have to use the additional RAM you installed, at which point it dies. Therefore, the RAM stick you installed is faulty.
Another possibility (although a very remote one) is that the new RAM operates on a speed which is incompatible with your BIOS. Also, as far as I know, the lowest speed dictates the overall RAM speed, so you may have a conflict there. Whatever it is - replace the new RAM.

Dont wipe your drive!! I had the same thing. I just put the xp cd in my computer and reinstalled all the damaged files. Put in the xp cd and boot into it, when the cd loads, select reinstall windows. Now it will show you the partition to install to, and it will search for previously download versions. Now that it shows you the partition with the os, select Repair. Problem solved
