Question about Biostar Computers & Internet

1 Answer

I am attempting to isntall a new biostar am2 socket micro board with a sempron cpu. I get everything connected, but when I turn on the power from the front panel, the fans will spin for a moment, then die and pressing the power button again will not do anything. If I turn off power from the back, then wait 30 secs, then turn it on then try the front switch it again spins the fans then dies. I have had this happen with two cpus (Athlon and now the sempron). I am not sure why this is happening but before I buy another item I'd like to see if I can get it to work.

    i took the cpu out, the panel switch turned the system on. I had to use the back switch to turn it off.

    I put the cpu back in, unplugged everything but power, and back to same action. I pulled memory and same on off result. I am not certain what you mean by two pins. There is a red jumper with two out of three covered. Anything else I can try? The biostar M800 motherboard should work with the sempron cpu chip.

Take out CPU and switch it on - do you get the same behaviour?
If so then CPU is probably wrong sort - check model of mainboard and CPU.
If behaviour is differnt then fit CPU and remove ram - if it beeps then CPU is working. Replace RAM and disconnect ALL other devices (hard disk, CD, front panel connect cable, reset button) just leave fans and power plugged in. now short out two pins for power on switch and see if it starts up.

    Hi

    There should be a front panel header which connects to your power button, hard disk led, power led ,etc.

    disconnect all of these.

    Then you can switch on the mainboard by shorting out the two links where the power button used to connect to.

    This is quite safe as these pins are only low voltage - low current.



    If you have mistakenly connected the reset pins to the LED, then the board will be in permanent reset when you switch it on, by removing all cables, you can make sure you have not misconnected anything.



    If it did not beep when you removed ram then the CPU is not running :-(

Can i replace my processor on my pavilion a1310n with a AMD Phenom 8750 i have an AMD Atholon 64 processor at the moment


Click here to view the specifications of the AMD phenom 8750. Your Athlon 64 CPU is for socket AM2, The Socket supported by the 8750 is socket AM2+ or AM3. Now this all depends on your mainboard. Find the specifications on either your manual for your mainboard or it is written on the socket itself, by removing the CPU cooler. You may also search for it on the net. If your mainboard is socket AM2/AM2+ then it will support it. However if is is just AM2 then it may fit but it might not work as it might not able to recognize the CPU.

I have at current a AMD sempron 3400+1.80GHz processor,socket AM2(940)core VID 1.100V,core speed 1002.2 MHz,bus speed 200.4MHz,HT link 801.7 MHz,stepping 2,L1 data and inst 64 KBytes-2-way,level 2 256...


The main thing is before you go swapping cpu there are some things to consider. 1. the new processor may draw more power than your current power supply can push out. 2. it will probably generate a lot more heat...both are bad..

But if you insist you can get away with an Athlon 64 X2 5600 or 6000+ cpu be careful though because some have different voltages which may not work with your board.

hope that helps.

Need a new processor


According to Compaq's web site, it takes a Socket 939 and the following processors:
  • AMD Athlon 64 X2 4800+
  • Athlon 64 4000+
  • AMD Sempron 3200+
Be sure that if/when you buy a CPU it is not Socket AM2, which is more common. You want Socket 939.

Can i use AMD phenom 9850 in m2n-sli deluxe mother board


According to all of my available resource's the processor needs an AM2+ socket but your board has an AM2 socket. So I would contact the manufacturer and ask them just to be safe, but I am sure that the board you have has an AM2 socket for the CPU.

Hope this Helps,

No Beep, No LED Read-out just - -


Sounds like you have pretty much covered about everything. Are you saying that the system works OK, except when you try to get to BIOS, or is it not working at all?

If you are just having trouble getting into BIOS, there is the possibility that something is wrong with the F key that you use to access BIOS. Might try a different keyboard if this is the case.

I know that this is kind of a stretch, but haven't been able to think of anything else, yet.
