No post, no beeps... Again.

[bennyboi117]

My computer has worked well for over a year, and one day I plugged in a USB gaming controller and randomly it would turn of and would have to restart the computer in order to get it running again. One time it locked up my computer and when I restarted there was no boot, no beeps, just a black screen.

I tested my RAM on other computers and it worked well, I tried putting 1 stick in and tried it on different slots and still no post.

I bought a brand new video card just for the hell of it and still nothing.

I tried booting with just the bare essentials with just the CPU, MOBO, 1 stick of RAM and just the video card and still nothing.

I came to the conclusion that the problem was either my MOBO or PSU so I RMA'd both of them and replaced my front panel and power switches incase that shorted out.

Asus sent me a better model mobo for me and Corsair replaced my PSU with a brand new one with full retail packaging.

I hooked everything up and all seemed to be running fine... Until I plugged in a jump drive to my front USB... Everything went to hell again.. No post, no beeps, just a blank black screen... :pfff:

I'm completely stumped on this one and would advice would be much appreciated.. This has caused me a whole lot of frustration and I'm finally taking this to the forums.

Specs:

Antec 900 Case
AMD Phenom 9850
Asus M3A32-MVP DELUXE/WiFi AP | M3A79-T DELUXE (After RMA)
OCZ Reapers DDR2 8500 2x2GB Sticks
ATI Radeon 5850 (Replaced older VGA card)
Seagate Barracuda 250GB HDD
Asus DVD Drive
Corsair TX750w PSU

Here's what I would do.
1. Disconnect the front usb panel connector from the motherboard.
2. Boot and check everything out
3. Use one of the rear usb ports with jump drive and see what happens
4. If you get same results with rear usb ports, I would suspect the jump drive
