motherboard = asus m3a78-cm. Windows 7 64-bit. 2 sticks of 2gb ddr2, 2 sticks of 1 gb
I opened machine and removed old graphics card (radeon hd 6670) and inserted graphics card (msi r7770).
When I started it up it gave several short beeps. I powered it down and removed vid card, double checked and discovered power supply needed to be 500w so I went and got a 600w psu. That did not work either, now no sounds made on startup at all. Tried replacing old graphics card, no luck, tried using onboard video connecter, no luck. Replaced cmos battery and used the cmos jumper to try and reset, no luck. Tried starting computer with one or no sticks of ram, no signal, no beeps.
At this point I will have to wait until tommorow to bring the moniter somewhere make sure its working, and so I am wondering if its likely then that I shorted my motherboard or cpu and thats my problem. Any additional insights before I spend money I dont have very appreciated
