Memory Upgrade results in No Video; Cleared CMOS..still not booting & no video
"Tom Scales" wrote in message ...
I guess I have to ask the obvious question first. You did take out the new stick and see if it boots, right? Yes, Removed the new memory and tried to boot with the old memory. (I realized after I posted that I forgot to mention that) |

typically, this means that you put incompatable memory in the computer. clearing the cmos wont help you here. Any suggestions as to what would help? Looking into this further I found PNY website- Memory FAQ (http://www.pny.com/support/faqs/readtopic.asp?modelID=6) "15) I installed a new memory module and my system will not reboot, even with the original memory installed by itself. What should I do? Answer 1. Verify you have the correct memory module for your system by going to our online system configurator. 2. The new memory module(s) may not be compatible with your system. The newer memory modules are manufactured with high density IC's (little black chips). They now come with 8 (on one side), 4 (on each side) or 8 (on each side). The design inside of the IC's on the Memory Modules may be too complex for your system to read and it may not work in your system. 3. Make sure the memory is seated properly in the computer socket with both clips locking on their own. 4. Verify the addition of the module does not exceed the memory capacity of your computer. 5. Test each module in the system to see which is defective by performing the following procedure for each memory module: Shut down your system Remove all the memory modules from your system. Insert one memory module at a time and boot the system up to ensure its compatibility After each module is successfully tested insert all modules into the system and boot up. NOTE: Place the highest memory module closest to the processor and work down. 6. If you have identified a defective module, return the memory module to the retailer (vendor) where you purchased it for an exchange. If the exchange date has expired, then contact PNY to obtain a Returned Merchandise Authorization (RMA) number. " |

I'm stuck. Without seeing it, this one is hard to diagnose.

This may sound simplistic, but I just had this happen to a client who
installed his own NIC card on his home system.. Check to see if all of the cards are fully seated. That was all it took to fix the clients machine. It seems that when he put in the NIC card, in pressing down to seat it her unseated the already installed cards. For a one hour service call All I did was make sure all of the cards were reseated, powered it up and it worked just fine. KC "Tom Scales" wrote in message ... I'm stuck.

This problem was resolved by a can of compressed air (and the magic
words "I need help here"). I've seen dusty motherboards - this was not like any of them. This one had just a little dust around the processor. Had previously tried booting after re-seating original memory ; booting with no monitior connected, then no memory hoping for error codes or beeping (even plugged in the speakers & turned them on so I might hear beeping, doh) The incompatible memory has been returned. This presario 7478 is booting with the original 64MB as if nothing ever happened. I haven't been able to get into the bios setup with F10 or Ctrl-F10 but considering I was looking at replacing the system board&/or processor, I'm not complaining. Thanks to all who took the time to respond- it helped. -Mary |

For compatible memory for your 7478, try:
