Hey Everyone I just happened on this site...hope I can be of service and hope someone can help me PLZ! I have a real strange problem with my PC! Ill try and be as brief and descriptive as possible! So this PC was built(Brand NEW) in March and on day 1 had zero issues...all of a sudden one day I powered on my PC and got no signal, so I just rebooted and all was well! Well it wasnt...see this problem happens randomly and some days my PC will boot first try, and others it can take 50 tries! It passes all stress tests, and all hardware performs up to spec otherwise and game on it for hours without any problems, and temps are amazing!! So heres the strange part, on SOME boots Ill get no signal and HEAR Windows boot up in the background via speakers! Others Ill get just no signal and the VGA led will stay lit on the motherboard! AAANNNd.....others Ill get no signal and the VGA led will stay lit and a minute or two later it will either boot normally or still have no signal with windows booting in the background! It gets stranger...resetting the CMOS or using the jumper corrects this every time...until the next time. Yep, I could be on the 100th try and ill pull the CMOS and it will boot every time on the first try! I go into uefi/bios and set to default(even though it is already) and Im on Windows seconds later! So an instant bandaid fix is uefi/bios reset! Now on to what Ive tried and what Ive canceled out! Its not my GPU as I put mine in another PC and booted the thing for a half hour straight and all was good! Just for bleeps and giggles I tried another PC same result...booted fine! I moved my GPU to the other PCIE slot and no go! Changed monitors, cables and went to HDMI and back to VGA! Still happened! Something keeps pointing me to some BIOS setting Im overlooking...I dunno why tho but I think somethings amiss! Ive also flashed and reflashed current and non-current bios for my board, flashed the updated bios for my GPU, Disabled secure boot and set everything to legacy as Im on Windows 7...I thought maybe it was something loose..so obviously disconnected/reseated/reconnected everything! Pulled HDD and just tried with SDD, tried with no SSD/HDD.....still happened! Im literally pulling my hair out! It literally booted just fine for 2 days and the past 3 its the no signal shuffle! lol...My last thing to try is swapping the PSU and RAM out...which Ill have access to tomorrow! Everything's under warranty and I don't want to RMA the WRONG piece of hardware if applicable unless someone here has a fix! Ive posted everywhere from Tom's to EVGA to ROG and NOBODY has an answer or Ill get no response! Im stumped!! Specs below!
