    I reported an issue where my PC would not boot up to the BIOS, OS or get any kind error when I would turn it on (thread is closed now). These are the specs:

    MB: ASUS M4A785DT-V
    RAM: Crucial 2 GB 240 pin DDR3 (2)
    CPU: AMD Athlon II X2 2.9 GHz ADX245OCGQBOX
    Video: XFX HD-435X-ZAH2 Radeon HD 4350 1GB 64-bit DDR2 PCI Express 2.0 x16
    PSU: Rosewill RP600V2-S-SL 600W ATX12V v2.01 SLI Ready

    I've disconnected all devices from it (video card, NIC, RAM, HDDs) and just tried again. PC turns on, LEDs light up, fans come on, but I don't see a BIOS or any type of error code (yes, monitor is connected :) ).
    So at this point I'm wondering, what would be the most likely failure? Mobo, CPU, PSU? Is there any way to isolate this? I can't even boot off a disk or USB to troubleshoot.

    You won't see BIOS without RAM? I thought you only needed the CPU connected.
    You're the second person to tell me the PSU is crap. Is it the wattage or is it just crap in general?

    it is not a recommended brand and only 72% efficiency

    todays computers require 80% efficiency or better and for pcie system i don't recommend anything less than a

    550w to get enough amps available on the 12v line

    you need both ram and video to get post
