I have a VPR MATRIX 1620 desktop. It has two memory slots. Only one slot was used with a 256k memory module in it. I attempted to install a 512k memory module in the other slot. I installed it upside down! I know......stupid! The computer then started up, but no video. The video monitor light was on, but no signal. I then re-inserted the 512k module the correct way, and still no video. What did I fry? The motherboard or one or possibly two memory modules?

That's not good.
You're probably getting no video because you have shared video RAM (guessing here) and the system can't find any RAM to use.

I'd take out both the memory modules (after touching the metal case to earth youself) and shine a good light in there to examine the memory sockets - any bent or mangled contacts? If there are you might be able to straighten them with a very small screwdriver blade and/or perhaps seperate them by inserting a piece of paper between touching contacts. Then working only with the undamaged slot try inserting the original memory module. (Without using the hammer this time. :thumbsup: )

If the PC boots well your back to square one but at least your working, you could try replacing that module with the 512MB module and see if you can get half an upgrade but that's up to you.

If the PC doesn't boot then I think it's time for you to order a new motherboard and RAM.
