No Beep, no video signal-on two systems simultanously

[titaniumacute]

Hi there,

Ever so often I get this urge to completely upgrade my computers but this time things going from bad two worse.

I dismantled a Athlon 1.1 and Athlon XP 1.7 system. Swaped the whole Athlon XP system into the case where the 1.1 system was and installed a new PSU, motherboard, RAM, graphics card and HDD into the remaining case.

I assembled the new system first, fired it up and...
mobo LED on, all fans running, HDD spinning, DVD drive making the right noise, but no beep at all and no signal from the video card. So I undid everything, just installed the essential components-and still no success. I found your site followed the advice of the sticky post (esentially what I already tried before) and still nothing.

So a assembled my tried and tested 1.7 system. No change in configuration apart from a different case (I also transferred the PSU). And guess what-I had exactly the same problem. Everything seems to fire up allright, again no beep, no error message, no video output. I could pull my hair out.

Has got anyone a bright idea? I must do something wrong. I don't believe it is just coincidence.

Here are the specs:

System one (new): PSU 480W (Dabs Value), Athlon 64 3000, Asustek A8N-E, 2*1 Gb Non-EC, Non-EC unbufferred PC3200 SDRAM, Gigabyte NVidia GeForce 6600 GT 128 Mb PCI-E ViVo, Seagate Barracuda 200GB SATA, NEC DVD RW

System two: PSU Q-Technology 300W, Athlon XP 1700, Gigabyte GA-7VR, 512 Mb SDRAM, Seagate 80 GB ATA, ATI All-in-wonder 128Mb, Lite-on DVD Drive

Thanks for your help.

P.S. To all mods-well done to your forum. The athmosphere here seems really friendly. Keep up the good effort.

Hi there,

I had a go at my old mobo again, cleared the CMOS-no luck. I started it without the graphics card and hurray-the speaker beeped. At least the board seems to be alive. I than started the board without the RAM-again this time another error code . So I replaced the monitor, but also this one would not receive any video signal.
Does this mean there is suddenly something wrong with my card? I will test the new board the same way tomorrow and let you know.
BTW: The keyboards would not light any LED (NumLock, Fn) up. I tried a PS2 and USB keyboard. Does it make any sense?

During all the moving around of parts, did you removed the heatsink from the CPU? If so, will need to clean the old stuff off and apply fresh thermal compound.

Hey tilo-

Just finished building my first system and had a similar problem. I had to rma the new parts and turned out to be a bad power connector. I would recommend trying the power supplies with the different systems (switch em) and also make sure u do the mobo out of the case on the cardboard suggestion. If u still got nothin u might be able to use a tester to make sure both parts of the power connector are functioning.

Good luck!

Hi,

Thank you for your answers. It is not looking good.
I have just tested the new board without the graphics card and still no beeps. Unfortunately I can't switch the PSU because my old board has 20 Pins and the new one 24
The tester idea is good. I should have one lying around somewhere. Will see what the new PSU is up to.
