cosrocket Posted July 28, 2019 Share Posted July 28, 2019 I have an HP Omen desktop PC with an Nvidia GTX 960 video card. A few days ago I got a Brother laser jet printer and plugged it into the wall, and a battery backup I have my TV and receiver plugged into beeped. I plugged the printer directly into a wall outlet so I don’t know why the UPS beeped, the PC is on a completely different UPS. The next morning I went to turn on the PC and nothing came on the display, it said no signal from hdmi. The video card has another hdmi port and 2 display ports, I tried all of them and no luck. So I took the video card out and tried another PCIe slot and got the same results, nothing. So I got an AMD RX570 card, installed it in both PCIe slots and still nothing. then I went out and got an Nvidia video card and, nothing. There is no video card on the motherboard as it has an Intel K processor. So is the motherboard for all intents and purposes fried? The PC powers on fine and the fans are spinning and the lights are on. I mentioned the laser jet printer only because I’m wondering if when I plugged it into the wall if something could have happened as the PC was working fine until then. if there is anything else I can try short of getting a new motherboard I’m all ears. Thanks. Link to comment Share on other sites More sharing options...

Billus Posted July 28, 2019 Share Posted July 28, 2019 A few things you could try: - take out the CMOS battery to reset the motherboard settings - remove the RAM sticks only leaving one in place - ensure the motherboard is properly wired, same as the hard drives From my experience, a fried motherboard will emit a smell if it is truly busted. Look for any blown capacitors as this is a sure tell sign that a motherboard has kicked the dust. It does sound unlikely that a power surge occurred as the PC was connected to a UPS but stranger things have bappened. In any casez good luck and hopefully you won't need to replace the motherboard. cosrocket and goretsky 2 Share Link to comment Share on other sites More sharing options...
Daniel F. Administrators Posted July 28, 2019 Administrators Share Posted July 28, 2019 also try removing any external or internal HDD's. I had a system that would not boot due to a bad HDD. So basically start with only 1 DIMM, CPU and iGPU or discrete PCIe and go from there Link to comment Share on other sites More sharing options...

THANK YOU! I did what you recommended ant it worked! I reset the cmos battery and switched the RAM modules and it connected to the display with the GTX 960 video card I thought was dead. Really appreciate your help! Link to comment Share on other sites More sharing options...
