Mega 180 beeps, no POST

Question

Ok I guess I need to sit down and tell you the whole story. I have a Mega 180 system that worked fine for two months (heck the best system I ever had) I decided to put the all in wander graphics card in to the system. I was going to the AGP slot of the motherboard of the mega 180. I went to the bios and saw something about high performance and about the AGP 8X knowing that my graphics card is for the 8X I decided to hit that save the Bios and shut down the system to put in the AGP card. After installing the card I started up my system and I got nothing to the screen, then the Mega made beep ever 3 secs. I shutdown the system by pulling the power plug. Waited 10-15 sec and tried it again, still no screen and the beeps. I pulled the plug again and uninstalled the graphics card. I again started the Mega up and switch the monitor hookups back to the built in graphs card. Still no screen and the beeps. My next guess was it had something to do with the Bios. I did the whole jumper thing and still got the no screen and the beeps. I even pulled out the battery and unplugged the power supply to the motherboard and waited 24 hours. Hooked back up everything installed the battery and powered up the system. And got no screen and the beeps.  Ok maybe it is something elese so my sister having the same Mega as I do a 180(and thanks again sis for you help and the trust to use you mega as a test base) I pulled every thing out of my mega 180 and installed it in her’s. I put in the Memory, processor, hard drive, DVD-ROM. It worked with out a flaw it was just like before. I even tested the graphics card with out going to the bios (real trust from my sis or did I not say this is what messed up mine oh well) and the graphics card worked fine. So after another time spent I put back together my mega 180 (with out the graphics card in the AGP slot) and still got the no screen and the beeps. I then tested what the on line forms asked. I tried to put in other graphics cards in the other slot to see if it was looking there for a card, no luck. Then I took the hold thing down to BEST BUY (they have helped out before good Guys there)  and they spent all day messing around trying to clear the bios and trying different memory and different graphic cards and no luck. They said to call in the warranty and see what MSI will do. (They did not charge me a thing for their time, and many of them I know want one now too even with this mess up I think this is the best thing out there in the world of pcs)
Ok so that bring us here and I thought to give you guys here a try be for I go ask MSI
Again thanks to all that help, I wish I could do more then say thank you.
Heck one more thing I would have done the redo of the flash the bios thing with the new file but the mega 180 does not have a floppy drive so no A drive.

Thanks for splitting this from the other topic to avoid any confusion.
I did use a can of air when I rebuilt my mega 180 after I tested all the parts in my sister Mega 180. And best buy looked over every thing and did not see any thing wrong.   (four eyes always are better then mine) At this point I’m out of ideas thanks again for all you help guys.   I guess I’ll send an email to MSI today and see what they say. (in a year or two I’ll hear something)   I thought it would be fair to start here before going to MSI. In all, I hope this is truly a rear thing that happens to mega 180's   for I still say this the best case to get. I love this case and I got two of my friends to buy one and my sister has one. We all love our Mega's a lot.   (Heating can be fixed with a little work ok) And the radio rocks and the looks cant be beat. I will keep you all updated and again if you all have any ideas please post them here you never know one day this might happen to you.
