Why won't my monitor display anymore?

[Mister Rious]

Hello!
I built my first pc about 7 months ago. Until now I've received no problems and it ran smoothly. However, I was using an old monitor (X2gen). About a week ago my monitor's screen turned white and froze but this issue seemed to resolve itself by letting the PC rest for a few hours. Earlier today I was online gaming and the monitor froze again. When I tried resetting my pc the monitor would not show any display. I tried moving some wires from the motherboard and putting them back but nothing worked. I even tried a newer monitor but the screen did not show. After 3-4 attempts I heard '3 beep noises' come from my tower when I tried turning it on again but nothing worked. I'm a rookie so I wouldn't be surprised if I overlooked something and it caught up to me until now. Does anyone know what seems to be the problem? Also, here are my specs.

MSI FM2-A75MA-E35
Corsair CX430 (PS)
Western Digital Blue Cav 500GB
AMD A10-5800K APU 3.8Ghz Processor
NZXT Technologies Source 210 Computer Case
Corsair Vengeance 4GB

Thanks for listening.

Do you have a graphics card or on board?

No. It's integrated in the APU

Hi

Double check the CPU heasink is still seated firmly and that the fan is working as intended by the manufacturer.

Boot with minimal hardware attached, PSU, MOBO, CPU & Heatsink, one stick of RAM

3 Beeps - Memory Read/Write Error in first 64KB block (check memory)

Test each stick of RAM individually in DIMM_1 slot
Test with a different stick of RAM; [borrow from a friend if possible]
Try reseating the memory [make sure it is firmly seated]
Run MemTEST
Double check bios settings, voltage for RAM is set correctly

AMI BIOS error beep codes
-1 Beep - Memory Refresh Failure [check memory]
-2 Beeps - Memory Parity Error in first 64KB block [check memory]
-3 Beeps - Memory Read/Write Error in first 64KB block [check memory]
-4 Beeps - Motherboard timer not functioning [possible motherboard replacement]
-5 Beeps - Processor Error [may need replacement Processor]
-6 Beeps - Gate A20/keyboard controller failure [possible motherboard replacement]
-7 Beeps - Processor Exception Interrupt Error [may need replacement Processor]
-8 Beeps - Display Memory Read/Write Failure [reseat or replace video card]
-9 Beeps - ROM checksum Error [replace BIOS chip or motherboard]
-10 Beeps - CMOS shutdown Read/Write error [possible motherboard replacement]
-11 Beeps - Bad Cache Memory - test failed [replace cache memory]

Confirm this is the Motherboard look here is fitted with AMI bios chip

Seems like it's definitely an issue with your motherboard. Follow Law-II's suggestions, but I'm pretty sure it will just confirm a motherboard issue.

Hello.
I did everything you suggested. The beeping noises are definitely gone but the monitor display still won't appear.

The DVI transmitter might have gone bust, it happened to a graphic card of mine, luckily it had two DVI ports so I just used the other one.

If you have a TV with an HDMI port you could test your PC on it. If it works I'd say it was indeed the transmitter. Each TDMS signal requires one so it should have another dedicated to the HDMI port.

EDIT: Does the VGA port work? It seems to be connected to the same pins as the DVI port so I guess they use the same transmitter (that VGA port isn't a "true" VGA port but the analog portion of the DVI signal akin to using a DVI to VGA adapter). If it doesn't work too I think that would be a definitive hint towards the transmitter.

If it turns out to be the transmitter and your boar is still in warranty you should RMA it. Alternatively, if the HDMI works and your board's warranty has expired, consider an HDMI to DVI adapter. Hopefully your monitor is 1080p compatible.

Tried it on my tv but that didn't work either. :/
Yes, the VGA Port works fine.

Online Gambling and Porn did it in, my condolences.

When you were "moving some wires from the motherboard" did you re-secure them properly? I would recheck everything you unplugged.

 

[TRWOV]

mmm, weird. I had thought it was the transmitter but if the analog portion works then it's something else.

Say, is there any option in the bios that says something like video output mode or something? Try setting it from auto to digital. (Caveat: I haven't seen any APU bios so I don't know if such option exists or not).
