Blerg, PC won't start up... :\

[Squally Leonharty]

A long time ago I posted a thread here stating that my PSU (OCZ PowerStream 520W)died on me, which caused the entire PC to shut down. It's now due for RMA, but it took me too long and I needed the PC for my project at the university, so I went ahead and bought a reserve PSU (Tagan TG380-U01 380W) and connected everything.

When I tried to start up the PC, all fans spin, but I receive no video and no sounds (from the POST reporter). It seems to receive power properly: it powers up fine, it resets fine (I can see that by the CPU fan changing speed) and it shuts down fine by holdingthe power button 4 secs long.

I'm going to test my video card (Asus EN7800GTX TOP Edition) at a friend of mine, to see if it's the culprit, but I seriously doubt it. I think that when the OCZ PSU died, it took the MB with it.

MB: Asus A8N-SLI Premium
CPU: AMD Athlon64 3500+ Newcastle
RAM: Crucial Ballistix 2x512MB PC3200
GPU: Asus EN7800GTX TOP Edition

What do you think? ;________;

Most likely is the motherboard, however CPU is second most likely. Both are fatal to POST.

Ive seen this numerous times first hand be the powersupply. In this case it may not be powerful enough.

Err... 380W ought to be just about enough, really. The manual states that a minimum of 350W for Athlon64 3400+, 2x 6600GTs, 2x DDR DIMMs, 2x HDDs, 1x optical drive, 1 PCI card and 3 USB devices. Well, if the PC is completely barebone, with only the CPU and RAM connected, then you'd surely expect that 380W is more than enough. 😛 Yet I don't hear any diagnostic sounds or whatever.

But I just got an idea, so I'll brb for now. (long brb, since I also need to catch a train soon...)

Either it's the MB or the CPU, but I'll see. >_o

I guess it's still either the MB or CPU, most likely the MB, though, since if it was the CPU (and the MB was fine) then I'd receive a POST Reporter message stating that there's no CPU installed or something. So yeah, I guess I'll RMA the MB... ;_;

Try resetting the CMOS yet?
