brucewayne1989 · Feb 20, 2016

i just built a new gaming pc, specs are:
m5a78l-m usb3 mobo
fx 6300 black edition
evga gtx 760 2gb
corsair cs550

after finishing the build i cant get a signal on my hdtv, ive tried everything, ive cleaned the ram and reseated, checked the cpu, cleaned the graphics card, tried different hdmi cables, different tv's, resetting cmos, switching from gpu hd port to mobo hd port, no matter what i try nothing works, please help

Have you tried removing your gtx 760 all together before trying onboard video on your motherboard? Is your system including fans powering on correctly, and just not showing signal to your TV?

I've tried it with and without the 760, all fans, LEDs etc are all working fine, no warning bleeps etc, I just can't get a display, I've tried 2 hdtv's and a vga monitor

Maye try moving RAM sticks around to see if you can POST that way. If all your cables and cards are plugged in good, and these ideas aren't working, your motherboard or possibly CPU(unlikely though)may be DOA.

Thanks for your replies, I believe I may have solved the problem, turns out my mobo bios is outdated and isn't compatible with my cpu at this time, so ive had to order a donor cpu to update the bios, hopefully that works because I've honestly tried everything at this point

How old is your BIOS? I figured that the FX 6300 has been around long enough that motherboards for sale these days should be able to support it off-the-shelf.

The guy that I bought it from told me the bios had never been updated, and the fx 6300 requires a 4010 update

1LiquidPC · Feb 21, 2016

I understand. This makes sense. Odd that they never updated the BIOS, but I guess if they never had a reason to, why would they.

Well I can not think of any other reason why it wouldn't work, I just hope it fixes the problem, I've tried everything, I watched YouTube videos troubleshooting for over 3 hours last night, what I find confusing is the guy claimed that he had an fx4300 running on the motherboard but never updated the bios, but according to the asus website the 4300 requires the same update as the 6300, so I'm not sure what to think.....

Any idea what revision your board is? Did it come w/ the original box? Possible it's written on there, though I'm doubtful. Your board itself should indicate the revision which may help determine the minimum version.

Switched out the cpu for a compatible one with the bios and still not working, now I'm completely at a loss, I have no clue what the problem could be....

If the CPU swap didn't help, and your 100% the BIOS version is compatible, it could also be the RAM, or even a bad/damaged motherboard. Some boards aren't compatible with certain RAM modules, they flat-out will prevent the board from POSTing. On paper just about any standard RAM of the correct type should work, but it doesn't always turn out this way. I've run into this many times over the years trying to swap out/upgrade RAM though it's usually on OEM machines. What make/model kit do you have? Have you had a look at the QVL compatibility list on ASUS' website?

Well yeah I've kinda come to the conclusion that it's probably the ram, one site said it was compatible, and another said it wasn't

1LiquidPC · Feb 24, 2016

I'd check ASUS site over others available. The ones listed are the "guaranteed" ones for being compatible. Many more modules should work fine though. Usually, it's the high performance RAM w/ tighter timings and/or higher voltage that can be troublesome for POSTing in some boards.
