I didn't read if the machine beeped at power up. Better than 99% do and yours doesn't.
Just 4 parts and if it doesn't beep then we are looking at what parts are likely faulty.
Hi Everyone, hope someone can help with this problem. I have a self built PC which has been running fine for about 2 years now. When I went to boot up this morning the hdd light stays on, all the fans (case, CPU, graphics card, and PSU) spin up. The power light on the front of the case does not come on but the small LED on the motherboard does.I get no output to the display or boot sequence at all!! Recently it has failed to shut down properly a few times (the power light and fans continue) but output to the display etc stop. Things I have tried; resetting the CMOS, changing the CMOS battery, unplugging the RAM and moved to different slots, unplugging graphics card （makes a continuous beep when I do that)!! Even tried unplugging the CD Rom, Floppy drive, hdd, graphics card and RAM but to no avail.Guess its one of these, PSU, Motherboard, CPU or RAM.
Asus A8N-32 Sli Deluxe motherboard.
AMD 4400 Dual Core CPU
Seasonic 600w power supply
Corsair CMX1024-3500LL Pro RAM 2 sticks
MSI NX8800 Ultra OC Graphics Card
OS Windows XP x 64
Hope someone can help me on this,
