    hi, i tried your suggestions, but the problem did not fully solved, most probabl there is a hardware problem in MBoard, i made the following traials:

    1.I replaced every thing in the system (CPU, Power supply, Ram and HDD)except the Mboard, but the problem persists.

    2.i installed windows XP on the HDD using another working system, and returned this HDD to my system, and boot the windows in safe mode, but the system stop when loading file MUP.sys.

    please help me to find a solution.

One q? I have for you, are you trying to utilize more than 1GB of memory? If so, your computer will not work and windows xp installation will NOT work at all.(I went through the same problem, I have an Atholon XP +2600 1.9Ghz, for some unknown reason windows xp does not like more than 1GB of memory) Also, remember to get all of the upgrades from after you complete your installation of windows xp. You'll upgrd to sp1, then sp2, then sp3 in that order, you can't skip, just play it safe. Believe me, I went thru 2 and a half days of hell! before my system began to work.
E-mail me at if I can be of any more assistance. Hopefully, I could help.

Did the computer work normally after getting it back from the repair technician? Although there are other causes, the symptom that you state (stops at stage of starting Windows setup) may indicate a memory problem. Download memtest86 and run it from boot.
Also. you may have conflicts betwen the cpu and memory. If you set the system switch on the motherboard to 133MHz, you should check your BIOS (under Hardware Monitor and misc.setup) to see if the CPU Host Clock is set to 133MHz. Also, set the CK_RATIO dip on the motherboard to "auto".
Another thing to check in BIOS is the interupt mode...set it to APIC. The PIC setting will hang on XP. Don't forget to save changes on exit.

Your BIOS may be corrupted. When in BIOS, check to see if you are running main or backup. If it's running backup, use the AUTO RECOVERY feature to restore the main BIOS.

Your problem might be solved by just re-setting the BIOS by selecting "LOAD optimized defaults" on the main page.
There may be other solutions, but try these first. Please don't rate this post until we explore other possiblities.

    Could be a memory problem, did you download and run memtest86? Could also be a hard drive issue. Insert your installation cd in the drive. When you get to the welcome
    screen select "to repair a Windows XP installation using recovery
    console, press R"
    It will take you to the command line. type in: chkdsk
    Let it run that, reboot and try to install XP again. Also, check your BIOS under "interrupt mode" and be sure that it is set to "APIC".

    .Thanks for the positive feedback and taking the time to vote.

    Sorry, but if that shotgun approach didn't work, my trying to help you through email is going to be very time consumming, not to mention frustrating for both of us.

    I recommend taking the computer back to the computer technician that you used originally. It sounds like he/she knows what he's doing and will be able to fix it for probably the same price as before.

    If you choose to pursue email, the only thing to do is start the troubleshooting process over. I will present you with _one_ question or task at a time. After you perform that task or answer the question, I need you to report back the result. I will then either ask you another question or assign you another task, and so on, until we fix this.

    Step one in this situation is to _verify_ that the Windows installation CD is OK. You will need to completely install Windows, using _your_ CD on another computer. If you don't have another computer available, you can take your CD to the computer shop and ask them to verify that it is OK. Should be just a small fee, if any. While you are there, tell him/her what's up, and they should be able to quote a ballpark price to fix your computer.

    OK, the ball is in your court now, I need to know if your Windows installation CD is verified to be good.

    Thank you,

    Sorry I took so long to get back. OK, the install cd is good. There are a lot of things to check, but I would like to test your computer memory first. Are you familiar with Memtest86? It is available here (free):

    If you need a program to burn the ISO file use (also free):

    Download the memtest 86 ISO file, burn it with Imgburn, put it in your CD drive and boot the computer. Insert a paper clip in the little hole in the drive door if you have to. Let Memtest 86 run at least 3 or 4 passes.

GA-7VRX Motherboard won't boot

Hi sebaswis, am I correct that this Gigabyte GA-7VRX is a replacement MB? (I read your other posted questions). You mentioned you put your old system back together & it worked fine. If mother board is shorted to the system case you will see the CPU fan spin for a second. Most motherboards use a green led which represents there is stand-by power running to the board.(This is normal). I am unsure why your led is orange. (Its not mentioned in your manual & manual does not show the led?s location). Was the other GA-7VRX MB led always orange or was it also green? Suggest you disassemble the heat-sink from the CPU. You mentioned you installed a new XP 2500+ CPU. If a pin on the CPU was bent during installation of CPU into the socket or if no thermal grease was applied or too little to the top of CPU, either would give you: CPU fan spins for a second & nothing else seems to run. Look over the link provided below. It is a guide to how to install a motherboard. (You may not need this but Its worth going over all the steps). As far as the power supply. If the MB's are the same (GA-7VRX) & the old system ran with 220W, the newer one should also function. Clarify these questions for me sebaswis. Mike

Computer won't boot. When power switch is pressed, CPU fan turns for a second but then stops. Nothing eles boots up, but an orange LED lights up and stays lit up on the motherboard. Motherboard: GA-7VRX...

1st. check your memory sticks, if you have two, flip\flop them around. if you can replace (don't buy them if you can until you are sure that they are damaged) or substitute them for a "lower" value & frequency range. Just to see if the computer turns on.
p.s. are putting the computer together for the 1st time?, Was the computer working before the problem? if so you could have said so!
