Hi All, First time poster. Hope you are doing well. I'm hoping to get some advice / opinion. I'm currently running a gaming computer and it has been fine for the last 6 months. However just the other day, I was playing a game and it suddenly switched off. I tried booting it up again but to no avail. Basically the symptoms as follows: Computer will not power on at all (no fans, hdd, lights etc) at all no matter what combination of pressing front buttons, PIN combinations etc I try. The weird part is this, whenever I switch my PSU on however, any device connected to a USB port automatically has power! Even though the computer won't boot up! So my optical mouse has a nice light shining from it when the PSU is on but the computer won't turn on. I'm hoping it is the PSU (somehow) but would like an opinion if possible. Look forward to your replies. Many thanks.
