Hi, A while back now (September '05 - yeah long time :x: ) I first started here for building my 'new' PC. And for the last week I have the PC fully assembled with all the components. But, I am having a problem.. When I try turning the PC on, my monitor displays "No Signal" from the graphics card (Gainward 7800GT 512MB), which is seated in PCIEX16_1 (Blue socket) on my Asus A8N-SLi Premium motherboard. I have checked and re-checked several times that everything is seated/connected properly. Here are the specs: Motherboard: Asus A8N-SLi Premium [Rev. 1.02] Processor (CPU): AMD Athlon 64 3500+ [OEM] CPU Cooler: Artic Cooling Silencer 64 Ultra TC Power Supply (PSU): Antec TruePower 480W Memory (RAM): 2x512MB (Identical) Corsair XMS3200 CL 2.00 [Seated as Dual Channel] Graphics Card (GPU): Gainward 7800GT 512MB Optical Drive: LG DVD-RW Dual Layer Hard Disk: Western Digital 160GB SATA I think my problem is around the voltage.. My motherboard has one 24-socket and one 4-socket ATX power connectors - my PSU has one 20-pin connector and one 4-pin connector. Would this be a problem? and would the solution to buy a 20 > 24-pin PSU Adapter? Im pretty frustrated by this So If you could help, I would be very pleased! Oh, When I tested my system with just barebones I got a beep code, this code was one loooooong beep followed by two short beeps. This was indicating a GPU problem. Strangely, I don't get this beep code anymore :x:
Hi, Is a VGA card another way of saying Video card? I can't find the PSU Adapter in the PSU, motherboard, or graphics card packaging.. if thats what you mean?
i'll just look at some websites (your motherboard manufacturer) and yes by saying VGA card i did mean graphics card
right, your PSU has both 20 and 24 pin connectors find then both then use the one that fits your M/B and just move the other one so its out of the way and plug the 4 pin plug into the 4 pin socket near the mouse / keyboard connector
Strange, My PSU has one 20-Pin connector and the 4-pin connector ONLY. But, I have found that I can use the 4-pin and 20-pin together to perfectly fit as the 24-pin. My motherboard manual says that If I don't use the 4-pin in the 4-pin socket the PC won't boot (which it isn't doing anyway).
strange, is this your PSU http://www.antec.com/uk/productDetails.php?ProdID=17481 because in the manual it says it has both 20 and 24 pin connectors
Ooops, your looking at a Antec TruePower 2.0 there The following link is the TruePower 480W: http://www.antec.com/uk/productDetails.php?ProdID=20480 Thanks
i don't know, your right it only has a 20 pin connector, sorry, hopefully BIG B will be abel to help you, cos he's THE MAN when it comes to PSU's
I searched on the net and come out with this.......this solution looks bit weared but still I thought it might help you in someway..... First, you can try an easy approach to troubleshoot this... Power up everything ( monitor, and the computer, with it's case removed..) and wait for the video to stabilze completely. OK, now first things first, I do this for a living so when I stress the idea of static damage to the computer, and what to do to avoid it, I mean it ! I'd hate to give advice that kills someone's system. First, touch the bare metal skeleton of the opened computer with both hands, to get rid of static. Next, while watching the monitor display, GENTLY tap on your video card once or twice and see if anything happens to the display.( If video is affected, see NOTE 1) If nothing happens to the display, touch the skeleton again, (static) and tap EVER SO GENTLY once or twice on the case of the cooling fan or the heatsink of your CPU, again, while watching the display. (If video is affected, see NOTE 2) If nothing happens again, that kind of confirms the connections are OK, hence, most likely, bad mobo.. You can contiune to do the "touch the skeleton, tap on something" to your other installed cards...any one of them acting goofy could easily affect video performance by causing hissy fits on the data and address lines of the CPU. ( and if it's not a critical card, you can always pull it and power up without it and see if things are OK.) NOTE 1: Either a) the socket on the mobo has a physical defect causing short or open circuits, or b) there is a bad solder joint on the socket ( the point where the legs of the socket are soldered to the circuit board) Case A is very difficult to determine without a microscope, so I guess Case A= new mobo. Case B can be checked, although not nearly as easily without a microscope. You will need access to the back side of your mobo, if you have a fancy case you can probably get it quite easily. Otherwise you will need to remove it from the case.( Touching the skeleton or something grounded, every now and then. ) You want to look, using a very bright light, at the little legs of the video card socket where they come through the circuit board. Then, move the video card up and down, or left and right, depending on how it's oriented, to cause a little stress on the socket. If you see any of the socket legs move, you have a bad connection, Either try to resolder it, or give up at this point if you don't know how. ( sorry..) NOTE 2: See CASE A in NOTE 1 __________________________________________________________ If none of this tapping method works, it really seems to me to be a bad mobo....the symptoms you describe, and how they actually change in some ways, seems to act like thousands of circuit boards I have worked on. That is how chips going bad, or connections going bad, tend to act. I guess it looks like your best hope is a bad, but re-solderable connection on the video card socket. Sorry I was so long winded and not-to-hopeful sounding, but look on the bright side, mobo's can be bought pretty cheap, and if you got a new one at least you'd know all your other hardware seems OK !
