Hey ya's. Having trouble with the Mrs pc. Every time I try to turn it on, we basically get a quite pop from the speakers and nothing happens. Been having trouble getting it going since power went off yesterday. I've unplugged everything not necessary (hdd's cept boot, all peripherals etc). When plugged in the power supply light stays on, but when i press the power button the power supply light flickers for a sec.It's a first generation i7 Dell XPS tower (I think first anyway) she's had for at least 10 years now and is used for photoshop etc. So maybe it's up for an upgrade (not gonna be happy with that cost). It has been sluggish for a while. It's left on 24/7 too. What I don't know is if it's a power supply issue, or motherboard etc? I was sure I had a spare power supply around the place but I can't for the life of me find it. It's not something I'd typically throw out. Any thoughts or wisdom?
