Hello all,
I'll try to make this short.
A month ago I found that my PC, a pre-built ASUS ROG GT51CA, would 'crash to restart' if during a game - i.e. something resource-intensive - after just over six minutes. I ran software based stress tests on my CPU, GPUs, and PSU. CPU and GPUs just fine, PSU um, no. I did the 'paper clip test' on the 24 pin cable and no fan. Thus I bought a new PSU with more than enough watts and of good quality.
After I had replaced the PSU, being very careful to install it correctly, I now got no signal on the monitor after the PC was turned on. All fans were running including the PSU's, LEDs lit up, etc. All was fine except for my monitor now showed No Signal.(?!) I of course double-checked all connections, I cleaned and reseated the RAM, etc. In the past, with plenty of help from the Internet, I have always managed to solve any PC problem. But finally, at my wit's end I took my PC to an obstensibly reputable computer repair shop.
Their diagnosis was not pleasing. They said my graphics cards and motherboard were both hosed, with "liquid damage." What?! I have never spilt anything remotely near my PC, let alone on it? WTF?
Anyway, I replaced the motherboard with the exact same model, and bought a new graphics card. Reassembled it all, and it turns on, boots up, and... again No Signal. Rechecked everything, still no signal. Being an idiot I bought a new CPU - exact same as the last one, and still no signal. I tried putting the old one back in, and now it won't even turn on. (Yes, I made sure my PWR_SWITCH was connected to the MB.) The LEDs no longer even light up.
What did I do? The new PSU is fine. Before, when my PC had a bad PSU, it would still boot up fine, just crashing when taxed with a game after six minutes. Why did replacing the old PSU with a high-quality new and fully functional one result in No Signal? Everything inside computer was humming. And how is it that now, new or old CPU, it won't even power on?
OK, that certainly was NOT short. Sorry.
But any help/feed back greatly appreciated.
