No beep, no post, no display

Overnight, my 3-year-old computer (self-built) doesn't "start". No USB connections work (i.e no light on the keyboard, no charging various things), nor do the monitors detect the computer - they'll go into powersaving mode once turned on and say there's no connection (both HDMI and VGA).

When turned on, the fans start and everything sounds normal, but the display is blank and no USB connections work. There is a blue light on the front of my case that normally remains on when the computer is on, this light is blinking.

I've tested both monitors and all USB devices - they work, so I think it's fairly obvious that this is a mobo/psu failure (with a slight possibility of CPU). There is no GPU in this machine as it was used primarily for light photo editing and work.

I've unseated the RAM, taken a can of compressed air to the computer to remove dust, etc, to no avail. I've also disconnected the computer from power and held the power button for 1 minute (was a suggestion I've read when googling).

Is there any way I can test to see if this is the PSU or the mobo? I could not detect any obvious issues with the mobo (eg. corrosion). I have no other computer with which I can test each component on.

I don't think this is an issue with the SSD, as that wouldn't explain the USB connection issues and the computer would still boot into bios if it were the SSD. Speaking of which, I have a laptop I now need to make my primary computer, can I just buy a SATA to USB connection to transfer any programs I need over from the old SSD (mx300)?

certain keys on my keyboard dont work when "cold"

Hi guys, i have a Lenovo Y520-15IKBN (80WK) and certain keys on the keyboard don't work (e,g,h,8,9,Fn...) but only when the weather is cold. for example in the winter it used to work after certain amount of time when i first boot the laptop and stops working when i stop using it for a while, but now that the weather is hot it works just fine except for the first couple of minutes or when its colder. of course i do realise that it has nothing to do with the outside weather but with the temperature of the computer itself. can someone explain to me why this is happening and how it should be fixed as i cannot take it to the tech service until july even though it's still under warranty because i need it for school. ps: an external keyboard works fine.

Old PC with a Foxconn n15235 motherboard needs drivers! Help!!

So my Pc corrupted and I had to fresh install windows on it, but now its missing 3 drivers and one of them is for the Ethernet controller! I've tried searching everywhere for the windows 7 drivers but all I seem to find are some dodgey programs saying they will install it for me. Problem is without the ethernet driver I can't bloody connect to the internet. I've been using a USB to try get some drivers on there, but they just end up being useless programmes . I'm also a bit of a noob at these things, I don't understand where to find the names of things in my PC, I've opened it up but I don't understand whats significant and what isnt. If someone has the drivers and can teach me how to install them I'd be very appreciative! Submitted April 29, 2018 at 02:47PM by darrilsteady https://ift.tt/2r76xMZ
