Please help my computer will act like it is turning on, all fans come on, cd drives starts, can't tell if hard drive is working. No light though, no beeps, and no signal to the monitor. My specs below
Emachines el1852g (all I could afford)
8gb ram (I upgraded)
Dual 3.2 ghrz processors
Nvidia Geforce gtx 650ti
400 watt power unit to run it all

The computer had been awesome, I have built it up myself from the base emachines model, have been playing bf3 with a random video card crash every once in a while, the screen would freeze and I would have to hold the power button to reset, we'll yesterday it did this and now it won't come back on. The computer starts, all fans gpu, cd, and hard drive from what I can tell, but I have no main light, no beeps and no signal to the monitor. Please help me

What PSU is that? It might not be providing enough power.

You should also run memtest for 5+ passes if you can get the computer to boot to BIOS to rule out a RAM issue as RAM can cause crashes.

If that's the PSU from the base eMachines model, it probably isn't capable of powering that. Remove the GPU and plug into the motherboard and see if you get display that way. If so, either the power supply isn't capable of powering the GPU, the GPU got damaged by the power supply, or the GPU died.

Ok so I took my hard drive out of my pcu at home ( one that wasnt working) took it to work to see if I could boot that computer with my hard drive to rule that out, because that hard drive actually came out of my work computer, because its a 1tb and i had 500gb at home, so i switched them. Anyway when i hooked it up to my work computer it came up with a black screen that said no boot device was detected, so does that mean my hard drive took a crap???? Is it possible that i was playing bf3, it froze had a nvididia kernal something or other that stopped working, had to do a hard reset cause it was frozen and it never came back on, because the hard drive got fried??? how is it possible? my hard drive is a western digital 1 tb sata /32mb cache wd10eadx.
