From Scott--- I recently moved home from college and was setting up my computer. When I tried to power it on, it did nothing, it had been working fine before the move. The mobo is a asus cusl2-c, the little green light comes on, so it's getting some sort of power. But when I hit the switch, absolutely nothing happens, no fan, no beep, nothing. I've taken all devices off of the board and unplugged all devices from the power supply, except the mobo of course. I've tried shorting the power switch pins on the mobo with the tip of a screwdriver (yes, i was careful), to test if it was the switch, still nothing. Took the mobo out of the case, thinking that somehow it was getting grounded, that wasn't it. Haven't tested it with a different power supply, could that be it, even though the light on the mobo is coming on? Could the CMOS battery be dead? Any suggestions would be greatly appreciated. Scott Follow-up The CMOS battery is not dead, just tested it. Follow-up If the PS fan is not starting either, I would try a different power supply. It sounds to me like that is your problem. Follow-up nope, nothing happens at all. I'm going to have to wait until i go into work on monday or tuesday to try a different PS. Since my last post, i've tried removing the ram and removing the processor, still nothing. Hopefully it's just the PS, and not the mobo. Follow-up I am certian that it is the PS. Most PS have a feature on them that prevents them from shorting out, insted of catching on fire and exploding as they used to....its happend to me about 4 days ago.....thats how I know. Follow-up Nope, it wasn't the PS. I think the mobo is messed up, haven't tried clearing the CMOS yet. It'll come on now, but won't cut off, gives me one long beep then nothing. Hold the power button for however long, nothing happens. Have switched out ram, vid card, processor, and PS; No change at all. So it's gotta be the mobo as far as i can tell. Thanks, Scott Follow-up Scott - I'm having a similar issue... Any suggestions or lessons learned?? Problem.... Computer will not power-up. (Yes, It's plugged into the wall. ;-) ) It's a 2000 HP Pavilion 9680C with a Delta Electronics, Inc DPS-160 Power Supply. Debug Steps Taken: * Low Level On/Off Switch Functions properly and is plugged into motherboard * Power Supply Fan / CPU Fan / Hardware / Accessories will not power-up when I press the "On" button. As far as I can tell, nothing has power. * There is no 5V or 12V supply at Hard Drive, CD, DVD, Floppy. ********************************* Does the motherboard / CPU power-up the accessories on boot-up or are they always powered? ******************************** It looks like the Power Supply is bad, but I'm not sure if the CPU has control over the Power Supply or if it is passive. Any suggestions? Follow-up Scott--- Same thing has just happened to me. CUSL2-LS which is very much like the CUSL2-C you have except it has an additional proprietary LAN/SCSI slot where a 6th PCI slot would be. I did everything you did too. Unconnected everything from mobo 'cept CPU and cables connecting to case, no response when I hit power button on case. I'm seeinng the green light and switched the power supply anyway, no difference. Tell me you found a solution. I tried shorting the power switch pins as well on the system panel of the mobo, no response. These are pins #4 and 5 if you count bottom right as pin #1 (this is my own scheme -- at work don't have the manual). For reference, pins #1 and #2 are for the reset switch. See bad ascii picture here where the asterisks are pins 4 and 5: .......... .....**... ----- pin #1 Oh man, I'm so ticked off right now! Tell me you found an answer. ASUS said talk to your retailer. Retailer said talk to ASUS. This board was bought in 2001. Businesses are selling replacements for the original cost of $292. I can buy a new P4 board for less than that and then I might as well buy a new computer. Help anyone if you can. Thanks.

I read the post 4 times and still dont know how many people are there! 1. Did you test with a good Power Supply? 2. Did you try clearing the CMOS? 3. Did you try to get to post with just RAM and video installed? 4. Is your power supply set to the proper voltage (115/220)? Please answer each only once. Good Luck.

Paragraphs 1,2,4 and 6 are from the original poster named Scott. Paragraphs 3 and 5 are from responder 1 who thought it was a PS problem. It wasn't a PS problem. Section 7 is from responder 2 who had a similar problem Section 8 is my post. To answer your 4 questions: 1. New PS didn't work. I bought a brand new one and used a working from a different computer. Neither worked. 2. I cleared the CMOS with a paper clip on the motherboard, no response with all 3 power sources. 3. I did 1 and 2 above with nothing in the mother board except the RAM, the CPU and the connector to the case's power button. It was even detached from the metal backing of the computer case. 4. The voltage on all 3 power sources is correct for the model of mobo.
