Fried motherboard ?

[Lord_Shuzen]

Hello everyone !

 

I found an old Z400 Workstation from HP in an electronic dumpster, brought it home, plugged it and it worked perfectly fine. I was really happy about it, especially since it was the one with an Intel W3520 CPU (4 cores/8 threads) and 6 Gigs of RAM. I decided to add up a graphic card to it to make it a cheap decent gaming computer I could use on the side. Since I needed a better PSU to power it up, I decided to plug in a Corsair CX750W to it but it did not boot. So after that, I plugged back the regular HP PSU but then it didn't want to boot anymore and I would get the motherboard doing this :

I tried unplugging RAM one by one, taking away the motherboard battery, unplugging the PSU and holding the power ON button down for over 30 sec, but nothing worked. I then found out that HP built their 24-pin in a way you can not use a regular PSU for those computers which really sucks...

 

Have I fried the motherboard ? Could it have also fried other components like the CPU ?

I could get another motherboard but it is actually the only pricy component there since CPUs cost about 20€ and RAM can be found for dirt cheap.

Oh yea you may broke it depending on if it not was already broken or your 750watt psu is broken ... but try unplug power cable and turn it on and off till all power is deloaded ! Unplug cmos cell and put it back after 5 minutes just to be sure .

And pls if its dirty clean that old board and stuff
