Another update. I replaced the cmos battery and tested the Radeon card, which worked with the TV via HDMI. I then reseated the 970 and that worked fine with the monitor and TV as well! My son was happily listening to YouTube whilst playing MTG Arena earlier today when the pc crashed. He told me that the screen went black but the computer was still on. He rebooted it but again, no screen. At this stage I'm assuming it may be something to do with the 970 drivers, or that the card isn't getting enough power somehow. Any thoughts? If I can get it up and running again I'll have a look at event viewer or BSV if it's installed.

Update time. A friend of mine came over with some cables. The 970 didn't post from DVI or HDMI, we didn't have a VGA cable to test that output. We tested the Radeon too, although this time there wasnt any output (same for when we used a different PCI slot). My friend agreed to test the 970 in his rig and it works! So I'm wondering if it's the MOBO or PSU. I'm going to try a new CMOS battery just in case, and then take it to a repair shop if necessary as I don't have a spare MOBO and PSU laying around. I'm not sure if there was a power surge now, none of my neighbours noticed anything and when I spoke to the shop owner they said their power had gone down due to the wiring in their building being faulty.

I've just been messaging my son. He tells me that he was at the computer (playing Hearthstone) when it died. The lights didn't go out in his room. I only suspected a power cut as a local business reported on too (so couldn't take card payments). I was only able to test the old GPU via HDMI, which worked (PC booted up on the TV). The monitor only has a DVI input so I don't think I can test it with any other hardware in the house (I don't even have a VGA cable to test the MB without a GPU). Hopefully testing the new GPU with a different monitor will shed some light on things. I'll try and source a DVI to VGA or HDMI cable/converter to test the monitor.

Thanks for the advice guys, please keep it civil though. I'll ask my neighbours if they experienced a power cut. A friend of mine will be helping me test the GPU with a different monitor.

The PC and monitor are both connected to a surge protected extension cord.

Since then the computer has been unable to post to either the LG monitor or TV I have connected to it via HDMI. After some troubleshooting (swapping RAM around, resetting the CMOS) I used an older GPU (Radeon HD 7750) and it was able to successfully POST and boot to the TV, although not to the monitor. From here I'm a bit lost. Any advice?

A quick browse and I found some pricings: Acer XB270HU £705.59 (£529.99 - out of stock) Acer XB271HU £689.99 ASUS PG279Q £688.70 AOC AG271QG £584.48

Would you recommend it over the others?

Yes. This isn't a new build, just upgrading. Why?

Hello, I'm relatively inexperienced when it comes to monitors, so I thought I'd ask here. I'm looking to upgrade to a 27" IPS Gsync monitor, although did like the look of the Benq XL2420G. My current system: CPU: AMD FX-8120 MB: MSI 970A-G46 RAM: Crucial 8G (2x4G) DDR3 GPU: MSI GTX970 4G PSU: EVGA GS 650W I've shortlisted a few options: Acer XB270HU Acer XB271HU ASUS PG279Q AOC AG271QG Please let me know what you think would be best. Comments about the system are also welcome, as I want to avoid bottlenecking. Thanks in advance.
