[QUOTE="jeallen01, post: 1094281, member: 176704"] This is to make you think and tax your brain a bit - a[I][U]nd WITHOUT searching for a solution on the net![/U][/I] PC: HP EliteDesk 800 G2, running W10 Pro. Problem: A couple of weeks ago, I tried to turn it on - but every time I pressed the "ON" button on the front panel the adjacent LED lit, but went out as soon as I took my finger off the button :-ohmy Simple, I thought, PSU's gone duff because it's quite old and been overloaded by the twin sat tuner which draws quite a lot of power (this PC has a quad core Pentium, an SSD as well as an HDD, and the PSU is only rated at 200W), and so I bought a tested s/h PSU and put that in today -> absolutely no change! :confused So, I unplugged as many of the m/b plugs as possible, and the power cable to the Sat card, until the LED wouldn't light up at all when I pressed the button ->still absolutely no change :confused Oh dear, sounds like the m/b is shafted :angry: - how much is a replacement s/h unit? => FAR TOO much! :( Finally, did a quick Google on the problem - [U][I]but DON'T do this until you've had a guess or two :)[/I][/U] - and the solution came up almost immediately, and cost me no more than a dead cheap part from the spares box! :D [/QUOTE]
