Long story short: I was running a computer with an FX 6300 CPU, M5A78L-M LX PLUS and a HD 7770. After almost a year, the computer shut down while it was running and then only ran for a split second before turning off. I replaced the PSU, exact same problem (used a CX430 then Antec VP450) so I decided the problem was with motherboard and replaced it. Now the computer runs but the monitor does not receive any signal. I tested the monitor with my other computer and it worked. I also tried to use the onboard GPU and still no video output. I even tried running with a single stick of RAM. Nothing seems to work. Also, all the fans run including the CPU controlled one. Please help.
Thanks.
Thanks.
