My computer was originally an emachines, but its pretty much a mutt now.I have changed or upgraded virtually everything in it accept for the mobo and the HDD. This morning, I was changing the case and now it wont boot up. I get stuck on the emachines splash screen and all my fans come on, and the lights on the keyboard flash once, but nothing else happens. I cannot go into the bios, my HDD led does not come on, I can hear the HDD spinning though. if I hold down the tab key while trying to boot, it goes to the boot screen and tries to boot, but gets stuck when it cannot detect the IDE drives. the mobo light does not come on. if i take out the ram sticks, it does make a sound indicating that there is no memory. if i hold down the F11 key while booting, it makes a constant beeping sound. I have tried switching out the PSU, but got the same results. Other than that, I cannot get it to do anything. is my motherboard fried?
