Let's try the usual.
1. Very few parts...
d. Power supply.
Nothing else. power up and beeps?
2. The CMOS reset jumper is ???
3. A documentation error has people put the HD LED on the reset and ... 1/2 the machines don't boot.
I just pieced together a new system for my girlfriend and I can't get it to
POST or anything. Here is the core hardware involved:
430watt power supply (can't remember the brand off hand)
Intel P4 Prescott 3.0ghz hyperthread CPU
ASUS P4P800 motherboard
1GB PC2100 RAM
chaintech nvidia geforce fx 5700le video card
currently it is doing nothing. the Power supply powers up, the hard drives spin, the fans spin. There is no POST beep or any sort of display at all coming from the video card.
I have swapped out the power supply w/ a 350 watt one I had laying around. I swapped out the processor for the 2.66ghz P4 that is in my desktop system. I have detached all periphials (hard drives, DVD drives, PCI cards, graphics card) so that all that is left is the motherboard, processor and power supply, and I still get no beep. And of course I octuple-checked the PC speaker to make sure it was hooked up properly.
Given the above circumstances, I am suspecting a bad motherboard but am looking for 2nd guesses. I put the 3ghz P4 chip into my system to see what it did, and I got a fairly rapid beeping with a high pitched beep then a low pitched beep in an endless loop when I booted-- my MB manual stated that this is the indication that no system RAM was detected. Strange, considering my 1/2 gig of ram actually was in the system. I didn't have my box hooked up to a monitor at the time of this test, so I don't know whether I was getting a display or anything, I really just wanted to hear some beeping to know that at least something was going on and the CPU wasn't totally dead. Has anyon
e experienced this before?
Once again, any ideas or tips would be greatly appreciated before I swallow my pride and take this box into the local computer shop for diagnosis. This is about the 10th PC I've built in my life, so I like to think I know what I'm doing . . . Thanks in advance for any help.
