i'm still having the same issue intermittently occuring: "no video signal". After relpacing the asrock extreme3 770 with another new asrock extreme3 770 through a newegg rma. Holding the power button down and restarting fixes the issue until it shows up the next time. When it happens the hdd activity light indicates a normal boot ssequence. All the fans including the cpu fan are spinning. The mobo lights are normal. In other words it appears to be a normal boot except there is no video signal. It does this with an hdmi cable to the monitor as well as with a dvi or vga cable. This issue has persisted after replacing the coolermaster ps 600 with another brand new one. I replaced the 955 cpu with another brand new one. I replaced the 5750 gpu card with a brand new 5770. i replaced the ddr3 ram with another brand with the same 1333 mhz (10666) 9-9-9-24 timings. i tried it with another brand of monitor (acer 23" hd led). I have tried reinstalling windows with only the latest amd graphics drivers, and asrock drivers. all my bios settings are default except as follows:1)advanced>storage confiuration>sata operation mode> ahci
2) advanced >chipset configuration>primairy graphics adapter>pcie express
3) boot>hard disk drives>disable (usb stick must be in before boot)
*cpu fan under advanced is set by default to "cool n quiet"
4) hardware monitor>cpu quiet fan>enabled >level set to 1
i have the one usb jumper set to allow wake up from hybrid sleep.
I HAVE NEVER TRIED ANY OC SETTINGS.
the power supply is plugged into an apc 750g ups
i have tried another new apc 550g also
in essence i have replaced everything i can think of and "no video signal" is still intermittenly occuring.
Is this some kind of known issue?
Is it possible there is a bios setting setting that woulkd fix this?
Please advise me with any possible ideas or settings to fix this troubling issue.
