Hey guys, thanks for your patience/helpfulness.

My problem is:
No video signal to monitor from either GPU or Mobo.

Detailed: Right now I am booting with two RAM sticks, receiving one beep from my motherboard speaker, receiving USB power, all fans spinning, required a soft shutdown ( long held power button) to turn off.

History:
Pc was working fine until I powered it on to receive no video, this was about 3 months ago, so unfortunately cant remember specifics about the problem then. I ran basic troubleshooting steps to no avail:
- removing one RAM/ swapping combinations etc.
- CMOS reset
- Removed GPU
- All steps on the troubleshooting thread on here.
My system was in a boot loop and not passing POST at this time.
After this I assumed my motherboard was fried, from reading peoples threads with similar issues, where a mobo replace solved their problems. Didn't work for me, so proceeded to replace power supply and CPU, rebuilt system.

Still no video, however the system seems to successfully POST (due to one beep from speaker, USB power, requiring soft shutdown, no boot loop). This has left me very confused, since the mobo, cpu and psu are all new I guess something else is to blame. Here are things i have tried after replacing mobo cpu and psu:

- Isolating both RAM sticks, no beep codes or errors
- Removing GPU and checking proper seating in PCI-E slot
- Changing hard drive to new empty one
- reseating cpu, checking for any excess paste
- Checking compatibilty of my components on official support sites
- Resetting CMOS
- trying different monitors, different ports (HDMI, DVI) on both mobo and GPU

I know this is a complex question, but i want to make sure the problem is explained the best I can. Thanks !!

Looked at this for a while and it's hard to say. You might have had two motherboards that still don't support the cpu that you chose with reason that they might have a too old bios.

Other option is to find,if you still have the output for it,a vga monitor to test with.

Which parts used? Exact names and makers.For ram means partnr as well,which can be found on the sticker or the box it came in.
