I have had a similar problem. I pluged in my dvd player via a usb cable and my pc shut down without notice. Now it won't boot up at all. It will turn on and all the fans run and I can hear the HDD start to run but no video or beeps. I think maybe the dvd player fried something. I've tried removing the ram, unplugging the usb cable from the mb but nothing works. The mb power led lights up so I'm thinking maybe the cpu is toast but I don't know how to check that and I don't want to buy a new one and find out that's not the problem. Any suggestions? I've also tried switching the hard drives but that did nothing.
Asus M2N-E MB
AMD Athlon 5200 CPU
4G DDR2 Ram
Nvidia 8600 GS video card
hope someone can help.
i'm having the same problem with my Hurcules RMX Dj Console. it worked fine on Desktop Siemens Fujitsu but then all of sudden when I plugged it in for next use it shut my pc down and wouldn't restart until unplugged. no worning no error message nothing!
I've tried several cables and nope - still don't want to know.. My brother has the same console so we tried his and the same happened so I know it's not a power surge form the console doing it. any ideas chaps..
