Question about ASUS A8N-E Motherboard

1 Answer

Asus a8n-e m/b gets power, will not post

Re-installed XP from Magnell Associates DVD. After install, got to the 'Learn XP' screen when both the keyboard and mouse quit working. Now nothing shows on monitor (all work on old Win 98 computer). Does not POST with speakers on. I've changed RAM around. M/B and DVD get power. Checked all connections four times. Restore DVD is no longer recognized. Can't boot into BIOS or safe mode since k/b does not work. EVGA 8400; Athlon 4000+; Corsair 400 RAM x 4 (512MB); Antec 550W p/s; Thermaltake CPU cooler.

    What is the voltage on the 3 main voltage power rails? (3.3 Volts, 5 Volts, and 12 Volts. All DC voltage ) Post back in a Comment. 1)

  • Merle W Miles Nov 03, 2012

    Thanks, Joe. I have not way to access the BIOS to find the actual voltages. Last I looked before the fiasco, all voltages were close to what was expected. Are you asking for the amps? Per the P/S lablel they are: 5V, Max 40A, Min 0.5A: 12V(1) 19A: 12V(2) 19A: 3.3V Max 32A, Min 0.5A. The dual rail does not max at 38A, but at 36A per the label. Hope this helps.

    Rec'd email to say I should add more information else this post will be closed, but no more suggestions as to what that might be. In short, the computer was working until the XP OS was fully installed, then the mouse and keyboard quit working. Thinking windows will many times fix the problem on reboot, I did that--but had to turn it off by pressing the power button. On powering it back on, the mouse, keyboard and the monitor would not interface. The m/b light came on, theDVD-RW got power and all fans were spinning. Without the keyboard interface I can neither boot to safe mode nor the BIOS. I doubt the problem is the power supply since it is obviously sending out power. It may be the processor, but after all the work I've done to fix the issue, I believe the motherboard went away. I could replace the m/b, but the oem XP license has been used requiring purchase of another. If it isn't the m/b, but the processor instead, the remedy would be far too expensive for what it's worth. Since a remedy does not seem apparent I will look into buying a more modern motherboard, processor, Win XP license and borrow a couple of sticks of RAM from my Win 7 build. FixYa people, thank you for having an interest in my problem. I know it's difficult to help 'long-distance' and I am interested in trying to help others on this forum if I'm able. If no other comments are forthcoming, it would be better to close this question. Again, thank you all.

    Power is always the first issue in diagnosing. Power Supply with a weak voltage power rail will not statrt the Processor. Or what I term a 'hiccup' effect of turn on briefly, turn off, etc. I would like to ask if you are installing over Vista, or Win 7? Also to note; You CAN use the same genuine Windows copy you bought, on another motherboard. Microsoft User's Licenese states, "One GENUINE copy of Windows per ONE computer." It also means it STAYS on THAT harddrive, it's cool. You DO own your copy of Windows, AND it is on just one computer. One harddrive. When you use the SAME harddrive with another motherboard, you should get an Activate screen to come up. (By itself) Suggest click on Call Microsoft. IMHO better to speak to a Human Being. Something goes wrong on internet, no one to talk to. Representative will ask what you wish. Activate is the answer. Just activate. If need be you can tell them you changed the motherboard, due to the old one is bad. When you clicked on Call Microsoft another screen will come up. This screen has 6 separate blocks filled with letter/numbers, and 6 separate empty blocks. You are required to read each block, one at at time, to the rep. After each blck set is read, the rep will read it back to make sure the rep heard correctly. 6 letter/numbers per block, and 6 blocks. When finished the rep will state, "Hold on". A small period of silence, then the rep will read back to you a series of 36 letter/numbers, ONE block at a time, 6 letter/numbers per block. Left-click in the first block. Type the letter/numbers from the rep. Read back TO the rep to make sure YOU understand correctly. Do Not want to make a mistake here. When finished entering 6 letter/numbers in the first block, the cursor automatically jumps to the second block. You do not need to click. When second block is filled, cursor automatically jumps to third block, and so on. When finished filling all 6 blocks, there will be a period of silence. This is because you are supposed to know, to click on Activate at the bottom right. You are deemed regarded as a tech when performing this procedure, and that is why. After you click on Activate you are done! HOWEVER, the product key that came with that genuine copy of Windows XP, is no longer vaild. You just put a new product key on. You ARE using Anti-Static Precautions, right? A Processor is the most susceptible hardware component to Static shock.

  • Merle W Miles Nov 05, 2012

    Thanks, Hans. FixYa has the m/b manual on this site, which is how I found FixYa. I have been using ps2 for both mouse and keyboard. I have located what looks like a bulging capacitor on the m/b. I believe that is the problem.

  • Merle W Miles Nov 05, 2012

    Joe, thank you for the informative email. I bought the computer several years ago through ABS, which no longer sells nor supports them. I gave it to my grandson a couple years ago, subseqently built him a Win7 system last July and now have the ABS back. Unforturately through my ignorance, I used the original hdd on my wife's system because hers had a mebroot virus I was unable to get off. I bought another hdd for my own Win7 build. Per your capacitorab link (excellent article and very good pictures), I do see a capacitor between the lower two pci slots that has a bulge. Now I no longer have the original hard drive and the m/b needs to be replaced. MS has been generous in the past re the 'number block' fix and it's certainly worth a try. Could save me $50!! I copied and saved your email to my documents folder for future reference. I hope that is Ok. If not I'll delete it. I've worked about another three hours on this today to try the things both you and Hans suggested so I would have answers-that-mean-something. I Googled 'replacing a capacitor' and fear I have neither the tools, supplies, nor the expertise.

Hello from here you can download a manual and drivers:

My guees is that the windows disk is damaged or burned to fast.

Since you not get any picture on screen now the graphic card. maybe malfunctioning try to change that and see what happens.

A ps2 keyboard and mouse must be used.
Because the usb function will not work until the system is fully installed.

A restore disk does not contains a full windows its only for repair

Good luck

Non-stop beep sound and won't display

A constant beep, usually indicates the post is detecting no memory installed. This is usually caused by the memory not being installed correctly or incompatible memory. double check you have the correct memory for this mother board. If you have 2 chips, install one and test. If this does not work swap the memory and try again. If both chips fail, you might try a different brand of memory.

Installing 750GB SATA on Asus A8N-E Mobo

Hello there.

I would not update the BIOS unless you are experiencing any problems. Try installing the new hardware first and then if you do experience problems, think about upgrading the BIOS. The latest version is 1013 FYI.

The new hardware should be supported without a BIOS update, as long as you have Service Pack 2 in Windows XP or above then all your 750GB will be shown. As for the memory you should see it list the new size in the POST screen before Windows even loads, or inside Windows.

If you do have problems, then please post back and we can help.

Hope this helps.
