Mobo fried? Beeps when startup but no video. I reseated ram and video card, with no luck. Both fans work and it sounds like it is booting. I tried older video card too but nothing. Thanks for any responses.

Try removing the display card and using the onboard VGA. Remove the BIOS/CMOS battery for about a minute and then reinstall it in the correct orientation. This will reset the BIOS/CMOS to it's default settings. You say it beeps once, this means that it is fine the mainboard is ok, it is not experiencing any problems. If it beeps in a continuous manner then it is the RAM that is causing the problems, I would say that the default settings may solve your troubles. Remember to enter the BIOS/CMOS when during boot up to reset the date and time by hitting the delete key. Also try entering the BIOS/CMOS even if you can't see any thing on screen, by doing this it may come up. let me know how it goes, I am here to help.

Thanking you

Dell D600 won't boot


I am sure Not the CPU or fan problem. Follow the below step to repair it.
1. Just press the power button 5 seconds or more to see the laptop can reboot or not. 2. replug the memory modules. 3. maybe the power supply device failed that the electronic volt is not enough to boot the laptop. Just replace a new Dell latitude d600 battery power supply.

Motherboard no responce



When you turn on the PC, normally the boot codes start at 00 and go up to FF (ex 00, 01, 02 etc..).
1.remove the ram memory and video cards if any .. 2. check and reconnect the power suppy wires for mother board , 3. dont worry about your operating system ...no data is lost . 4. if u have not heard any beeps while booting then ...it could be the ic chip ...reseat it properly and make sure it is properly locked . 5. check the fan ...the chip can will over heat when the fan malfunctions ..
this should help ...based on info provided by u , provided u take atmost care while opening or reseating the mobo items

good luck..!

My pc doesn't boot anymore.


This code usually refers to a Video card or RAM issue. Try reseating both the video card and then RAM to see if it fixes the problem. If not then try removing the video card and rebooting. If the system starts without the beeps then you'll know the video card is bad and you can replace it. If it still beeps then try removing the RAM one stick at a time, rebooting after each removal. When it boots you'll have the bad RAM stick isolated and can replace. Hope this helps.

No beeps on boot up with asrock mobo? help plz


While booting BOIS goes for POST check for detecting the all the hardware .

Disconnect all the connection to DVD, HDD, FDD from MOBO.
Rmove all RAM and start the ssytem from testing RAM Serviceability. If you listened a long intermittent beep place a single pices of RAM in MOBO ( repeat test with other RAM also).

Other wise your video card is unserviceable, if you have any addon plugins like NVIDA graphics card you can check
