Fair enough, looking like the mobo...but I still get an itch that says PSU...My secondary machine would only power up after being connected to the mains for 20 minutes. If it was left plugged in, no issue. Main resevoir capacitor dying and rather bulgy...
I don't like spending pennies, never mind pounds. Basically, I'm a tight git.
Agree with all of that! What's the actual spec?
i7 3.4 GHz processor, 16gb RAM, 2TB HDD, 500W PSU and nVidia graphics (can't remember exact one)
If it's that, it might be easier to just replace the motherboard.
You'll need an SMD rework station ideally. Realistically the situation you describe is never good. Usually if the bios can't even beep at you to indicate a fault then the motherboard is always number one culprit for me. Other than resetting CMOS as you have tried, you can only do as has been suggested. I'd go as far as to remove everything off the board including CPU to see if the board reacts differently when powered.
Definitely don‘t have one of those
As I’m going to try @DCBassman ’s suggestion of checking the back of the motherboard, I can do this at the same time. I’ll report back.
Next for me is to replace desktop’s boot drive with SSD (using old HDD for storage only, waste not want not). SSD and mounting bracket plus cables ordered and on their way. Then that PC will be done until I can eventually find a smaller case for it rather than the large and unwieldy one it’s in at the minute (but that’ll come much later). Then I need two need laptop batteries to finish those off.
This, always this. But my take on it is to get a 128GB SSD and leave it all to C drive, rather than partition a bigger SSD. Then it can be left entirely to its own devices, yet has plenty of space for whatever Windows wants to do. Every month or so, I run Disk Clean-up, including system files, to get rid of junk and install files and keep the system drive as clean as I can. Seems to work, this machine screams along!
