Nothing from PC, is it dead?

  lahorie 10:47 11 Sep 07


My PC just stopped working, the monitor light is blinking like it's in sleep mode but i dont get anything on screen on bootup, not even the BIOS screen display.

I've changed the graphics card, installed some spare ram i had and even changed the hard disk to see if it woulod boot up but nothing, i also tried these components in a differnet machine and they work fine, the processor is working and the cooling fan spins, the cd opens and closes but i get nothing else what so ever.

Any help please?


XP Pro, 1GB RAM, Intel Pentium 4 processor

Have you checked monitor cable - loose! (both ends).I have had a cable bent at 90 degrees which caused to cables inside to break. Try a different monitor.

Most likely to need a new moniter - sorry!

do you hear any beeps when you turn the computer on? if it beeps once, the power on self test has passed...

i wrote a program which tells you what all the beeps mean.. you can download it from here

Thanks Guys.

Sorry should have added checked monitor too and monitor cable, i don't get anything at start up, no beeps nothing, the hard light disk light flickers for about 5 seconds then nothing, just a blank screen with the power on light flickering every 2 or 3 seconds.

It was ok 2 days ago, i haven't downloaded or installed any hardware/software.

I shut down as normal and now this...

have you tried it with your old ram and new graphics card?

Hi Brad G

Yes i tried every combination i could think of, i dont think its the RAM or Graphics as they both worked when installed in a spare machine together.

hate to say it...... but could be your processor

  Brad G 15:01 11 Sep 07

sorry i retract my last post... the reason i said this, is that i had the same symptoms as you had a few months ago.... it was my motherboard.. not my processor. but that doesnt mean it will be the same in your case... food for thought

Hi Brad G

I'm thinking about swapping the power supply, i know it's a long shot but worth a go, if it was the motherboard, would the cd drive still open and close, there is a led on the motherboard which lights up when pc is powered on....

yes the cd drive will still open, the hard drivs may even spin up, the lights on the mobo will be on. certaoinly worth testing your PSU . i have a tester i brought from ebay, and they prove to be invaluable to keep in your toolbox
