ok....
i have read other threads that talks about this but i still don't get how to fix "MY" computer....

so... my computer worked fine....

and then. one day... my monitor suddenly doesn't turn on for some reason..
well.. my monitor works cause i tried it on other computer that i have..
but my monitor is still in standby mode... (it seems it doesn't know that computer is on... it doesn't have "no signal" thingy floating around.. so i know that it is not the cable that I'm having trouble with..)

hmm.. so.. i will tell you in detail what happens when i turn my computer on..


so.. if i plug in the plug..
the LED light on the back turns on
when i press start button, LED light in the front comes on..
for some reason.. my both cd drives are down.. there is no light and i can't open it...
CPU cooling fan and power supply's fan spins fine...


any ideas??
btw... i don't have graphic card. My "thing" where u plug VGA thingy (please tell me what you call it) is on the motherboard... please help!! thanks so much

my computer is XP Home Edition

From your discription I would suggest first try another monitor if you have not already but Im guessing it also will not work.

I believe your motherboard is not putting out any signal and that is why your monitor is not coming on. Probably because of a power supply problem or mother board problem..

From you reference to "thing" above Im guesing that repairing it yourself is beyond your technical ability so you will need to take it to someone to repair. If it is under warranty then take it to the supplier.

Otherwise if you are up to it you could check the voltages from the Power supply and or replace it and check all mother board connections.

Information on power supply voltages can be found here. http://pinouts.ru/Power/atxpower_pinout.shtml

@ dai..

well.. it's my dad's office computer.. so.. i don't really know the video card cpu ram but.. i will try to list what i can...
so..
m/board is MS-6577 Ver: 4.1 ( is that right?)
power supply: Bestec Model: ATX-250-12Z Rev.: D2
Input: 100 - 127V~6A, 200 - 240V ~ 3A 50/60Hz
Output: +12V = / 14A, -12V = / 0.8A
250W Max +5V = / 25A +5VSB = / 2A peak. 2.5A
+5V & +3.3V 165W MAX. +5V & 12V 218W Max..
(uh.. = is something like - and ... this kind of thing right below..)

Brand = COMPAQ...

Re: My monitor doesn't turn on..

see what this gives you

http://www.cpuid.com/pcwizard.php

see if can borrow another psu larger wattage to try in it it sounds like your 12v line has dropped enough to cause the problem
uh.. how do i do this checking when i can't see anything???


and please excuse my lacking knowledge but.. what's psu larger wattage?



ps.. wow.. that thing you sent me is SO COOL!

Re: My monitor doesn't turn on..

Lykfe,

Bottom line is you probably have a faulty Power supply. Big question is are you capable of replacing it.

If this Compaq pc is standard and you have not added anything to it then the power supply is just faulty. If you added hardware to your dads old Compaq then you need to upgrade the power supply.

The original on is a HP / compaq part is a 250 Watt Power supply see here:

http://www.censuspc.com/Bestec-ATX-...X-Power-Supply--HP-P-N-5188-2622-pr-3129.html

If you need one with more power you will have to get a power supply with the same connections and mounting but more power output 500 wats or more. Take the faulty one to a compter parts shop and show them the old one. They may even test it for you.

No guarantee replaceing the power supply will fix it but thats the best guess so far.

@dai
I don't think he can run pcwizard if the PC does not turn on.
