I just bought 2 gigs of RAM to upgrade my memory, but it wouldn't run. I currently have a 1/2 gig of RAM and when I put that back in the computer everything was OK again. I bought the RAM they told me to buy. What do you think is going on?
Well it could be a lot of things. Did you put them in the proper slots? If you have 4 slots they are usually paired and color coded so that when you put in 2 sticks of memory they should both be in the blue or the green slots (or whatever color your motherboard comes). Also inspite of some guy at a store telling you it's the right stuff they might have sold you the wrong stuff. When I cruise the various forums for motherboard mfgs, one of the biggest problems people have who build their own systems is the RAM chips not being compatable with their system. There are things that you could try changing, but it requires that you go into your computer bios and changing the timings for the chip and while you won't blow up your system with the wrong settings it's likely you won't figure out the correct settings without some help. I'd take them back to where ever you bought them. Nowdays most computer places will install the ram for you, and if there is a problem it'll be discovered before you leave the building. Terry
Not much to add to that except possibly this: Memory can physically fit the slot but be the wrong speed. This is especially true if you purchased a different speed than the memory that was originally in the system. Under some circumstances, you can totally remove the old memory and install the new memory. If you were having the problem with both the old and new memory installed, try removing the old and retry.
My motherboard has only two slots for memory. I put a one gig module in each slot and it doesn't work. I've tried every possible configuration and none of them worked except one: I put the old memory back in and that worked...
