Occasional POST Failure

[CrazyTom2k2]

Hi there!

 

I'm new to the forum, sorry if I've got the wrong thread. Thought this might be a good place to come and get some advice about an issue I'm facing with my custom build PC. Pretty much, the issue is that my machine will normally boot up fine, however I've noticed that my machine will sometimes fail to POST and will beep - 1 long, 3 short - which I think might be a VGA issue beep. I'm thinking I might need a PSU upgrade, or the Mobo might be cooked idk. My machine's specs are:

• CPU - Intel Core i5 7400 - BIOS Version 4202
• Mobo - ASUS H110M-A/M.2
• RAM - Crucial 16GB DDR4 2666MHz (running at 2400MHz as 2666MHz makes the POST fail)
• PSU - Cooler Master Masterwatt Lite 400w
• Boot Drive - Crucial 512GB NVMe SSD
• Other Drives - 3TB Seagate HDD, 500GB Seagate HDD, 120GB WD Green SSD
• OS - Windows 10 Pro x64

Sorry if I've missed anything out, and thank you for any help!

All the best, and keep being awesome!

Tom

I had similar symptoms when CPU retention arm was not tightened.
