Another PC problems...

not beeping..the fans running quite unusual..does it broken?

if it doesn't beep at all then yes there is probably something wrong. my guess would be either power supply or motherboard failure.

meganovaForget about that problem.
I have new problem!!
When I turned on my PC the screen goes black with a message "no signal" and my CPU have both green and red lights..but no picture comes out on the monitor??
I've tested the monitor on other CPU it works fine though...."the problem come one after another"... :(

um, i think the one of the cable is unplugged. it happens in our school with the lcd projector. check the cables.

I think not,
because all of the required cable are connected to motherboard as well the monitor cable.

It could still happen...it happened to mine.... I had to whack it a little bit (System unit) just so I can have it working again....It's either the connections or just check inside the system unit to see if there is something wrong there.

Maybe I need to run the Flash Bios?

NO. Flashing the BIOS is the most dangerous thing you can do. If the PC has worked fine before then the BIOS does not need flashing, and if you flash it you run the risk of permanently killing the board.

Uhuh,
Then?what should I do?

open the case and check all the connections, turn it on and tell me if the CPU fan spins, also if theres disk activity (either listen to the hard disk, or gently put your hand on top of it (NOT the side with the circuit board) and you should be able to feel it spinning. If there's any lights on the motherboard tell me that too.

CPU status :-
Processor fan - Spinning
Motherboard LED - Okay
Hard Disk - Okay(I mean,when I put my hand on top of it,there's a vibration)
CPU fan - Spinning(but I'm not sure whether the loud noise come from CPU fan or Processor fan)

The first time u boot ur cpu, is the screen goes blank or there is bios display (like usually)?

OK, so we have power to the board. Now, unplug all the drives from the board (and their power connectors, label them if necessary) take any expansion cards out (even the graphics card if you have video built into the motherboard, otherwise leave it in), remove all ram modules except the one closest to the processor and turn it on. What happens now?

Still blank..
I think the problem is either power supply or processor....

I don't think so, maybe it's just the head conector of your vga card... if ur m/b or processor is broken, it won't started at all.

It isn't starting. It is getting power. Nothing more.Remove the last ram module, and does it change anything?

So it was blank screen? Not even the bios display? Than it's definetly a cpu problem, but did the cpu made a beep sound? like if a ram problem than it will beep long, and if a vga problem it will beep twice short.

the beep codes actually depend on on the bios, different bioses have different codes. He's already said there's no beeping.

No,still blank.

No beep sound.
and I think the processor or power supply is the problem..

do you have access to a multimeter/voltmeter? (or a computer power supply tester is the easier option)

Did you mean a hardware?
