Solve : No power on new system? |
|
Answer» In October the M/B I was using went out. I shut it off one night and the next day , it would not power back on. i decided to upgrade. I found an Athlon 64 +3400 procwssor paireed with a PCCHIPS M/B M861G with 256 DDR Ram and made the purchase. The PCCHIPS board has integrated video and audio. My older system had audio on board but I had a Radeon VE 32mb vid card. The new M/B wouldn't recognize the Radeon VE. In October the M/B I was using went out.

My older system had audio on board but I had a Radeon VE 32mb vid card. The new M/B wouldn't recognize the Radeon VE. That is one problem. The place you sent it in to may be another and the the build is suspect as well. Assuming the board and processor are good (which I don't) you should strip it down to just that, one stick of RAM and the video and see if it posts. I PLAN to return the PCCHIPS board and hope to get a refund. I have since gotten an ASUS board model # K8U-X with an AMD Semperon 3000+ processor. I tried it today with the same results. Here is an odd finding. With both of the power supplies plugged into the M/B, the power does not come on at all. I unplug the 4-pin +12 volt line and the p/s comes on, but the system doesn't boot, it just sits there. I used the gold/copper colored stands to mount the board with. If by plugging the 4-pin into the M/B, can this cause a short? I am at a loss and stumped/I would do a bench test on that machine. On a rubber mat assemble the MBoard, CPU and fan, 1 stick of RAM, vid card and keyboard and mouse... Let us know. p.s. i suspect it is shorting out on the case.A bench test at home is something I've never. I understand all the instructions, but there's one thing I don't get? With everything outside the case, what do I use as a power switch to turn it on? Do I sit the case next to it and hope the wire is long enough? I need a little more help. Thanks MikeYes if the case is CLOSE enough the PSU cable should reach...if not remove the PSU from the case...The PSU leads should be more than long enough. I was REFERRING to the switch from the front of the case that plugs into the M/B that turns it on. What if it's not long enough? :-?I have now bench checked both MB's. The MB, processor, heatsink/fan, 1 stick 256mb of DDR400 RAM and vid card installed onboard. I hooked up the mouse, keyboard and monitor, then the 20 and 4 pin power leads. I used the power switch mounted on the case. I didn't use a HDD. When I pushed the power button, nothing happened. I shut off the power supply. Then unplugged the 4 pin power lead. Turned the PSU back on, hit the power button. The PSU came on, it has a 120mm fan in it. The CPU fan came on and it sat there doing nothing. Both boards did exactly the same thing, nothing. Can I assume that these MB's are both bad? If the polarity on the 4 pin lead is connected wrong, can that "fry" something on the board? The PSU that I have has a 4 pin lead that mates together with the 20 pin lead for a BTX MB. When I slide them apart, there is no definite way to determine which way to connect it. I have sent a request to their Support people and am waiting to hear. Their site and manual, neither one have a color coded diag. The 4 wires on that lead are 4 different colors. I'll let you know.Hey Patio and everyone who has followed this thread. I found the solution. I was browsing through older threads and came across one with a similar problem. Check this out, it's a bit from that post. It's originally dated Nov 5 '06. wightrob Newbie Posts: 17 Re: Rebuilt PC will not start. Reply #5 - Nov 6th, 2006, 11:35pm OK folks, it has been sorted. I received postings on another forum indicating that I may have used the wrong 4-way connector to the motherboard. This turned out to be the case. The Blue Storm manual which is in black and white only shows the 4-pin motherboard connector on the same loom as the 20-way connector. The correct one is in fact the separate 4-pin plug with 2 yellow , 2 black wires. Thanks for all the positve comments. Rob Back to top The PSU that I had, is definetly bad and has only one 4 pin lead. The new PSU I bought, at first, only looked like it had one. After reading that old thread, I looked at my PSU again and found some SATA leads and a funny looking blue 8 pin connecter. I looked closer and found that the 8 pin was actuallly 2 4 pin connecters interlocked together. I separated them, put it all back in the case and shazam! Everything works. Apparently this other lead is strictly for use with a BTX MB. I don't have a clue what that is. This has been a hair pulling experience. You'd think everything would be fine, not quite. I got WIN XP Professionl 64 bit installed. I went to install the board drivers from the disk that came with it, and got an error message. It said, "The files on this disk are not compatible with this type of machine". Go figure! The disk doesn't have the right drivers. I will post another question about this in the Software forum. I just wanted to update all of you. Thanks everyone for trying to help. Mike |
