Okay you are having a Memory Dump which could be attributed to 2 things. Bad Sectors on the hard disk drive that Windows is currently attempting to use as Virtual Memory. The other is obviously RAM.
Let's address both but let's focus on the RAM issue since the problem obviously is a result of the new memory.
Let's get the hard drive out of the way 1st. Running a simple SCANDISK surface scan should do the trick. However, I reccomend running the Disk Defragmenter as it will do a much better job (if you have a lot of data).
Okay, RAM....
When you purchase RAM, if you bought it from a "Good" dealer, The salesperson should have asked you for RAM Spec's.
When it comes to RAM, obviously there are several physical types. But it goes on further, there is BUS Speed, Clock Speed, Voltages, and of course method of chip layout.
Now when you go to buy RAM, take with you these basic specs.
TYPE: Physical Module (SDRAM, DDR, SIMM, SODIM, RAM Bus, DDR2)
Bus Spped: PC66, PC100, PC133, PC400, PC800, PC2100, PC2700, PC3200)
Current Configuration: How much RAM do you currently have? How many sticks of RAM do you have? How many RAM Bays do you have Total?
Now I say remove the newly installed RAM. RAM is not somthing you configure. It runs off of static electricity to maintain it's data. It either works, or it doesn't. There's not too much you can do other than remapping memory allocations from within Windows and that's not something you can learn here...
Exchange the RAM after you have detirmined exactly what you need. Most people have the hardest time with the Bus Speed and the type of RAM they have. Here's a few easy to remember rules.
RAM Bus Speeds get larger as they improved technology. You'll see what I mean in a sec.
RAM Type also is specific to Bus Speeds so detirmining what type of RAM you have is a great starting point. Let's start with DESKTOP RAM. SDRAM is pretty much the oldest RAM you're gonna run acrossed in modern day PC's. SDRAM was available in 3 Bus Speeds. PC66, PC100, and PC133. SDRAM is easy to spot by it's distinct 2 notch alignment grooves. Only one other RAM type has 2 notches, that's RAM Bus. It's two grooves or notches are close together. SDRAM's notches are spread out. 1 in the center of the pins, one near the end.
DDR comes in Bus Speeds of PC2100, PC2700, and PC3200. DDR RAM has 1 notch off centered.
Okay now we have RAM Bus. DELL users, This may apply to you. RAM Bus was the technology that started the whole SDRAM/DDR thing. Running at PC800, this RAM must be inserted in pairs and the unused memory banks must be terminated with specially designed bank terminator memory modules that don't do anything but terminate those unsed banks.
Now you need to make sure you know how much RAM your motherboard can support. You can just go out and by 4 gig's of RAM and stick it in an old 1 GHZ machine and expect it to work.
The easiest way to detirmine your RAM type is to pull out your existing sticks and jot down the numbers off the stickers. If that is not up your ally, then you can try a nifty tool called "CPUZ" available on my Tech Support Site, http://Groups.Yahoo.com/Group/ComStar_Support
