Well first of all i hope this thread is not in the wrong place.:)
I have searched about this problem i have for a few hours now
but nothing. After opening the PC to check for some overheat problems i had, i cleaned the fans, changed the CPU cooler and everything. That's when the problem started. PC booted once more but nothing since then.
I have checked for Power problems by removing 2x RAM and a VGA,
I have tried a different monitor. I have removed everything from the PC to "try" and find which hardware was not allowing me to boot but still nothing. Its a same cause i have this PC for 3 months. Sorry for my english and thanks in advance.

will need some more information quick.

1) what happens when you power on, get any video at all? fans turn on? any lights on the computer?

2) when you say you removed everything from the PC, do you mean you took all the parts out or you unhooked all of the connections from the motherboard? and when you did this, what did you leave connected to the motherboard?

3) just removing memory and a video card, honestly is not a way to check for power problems. only two ways to check for a power problem, one is to try another power supply that is known to work, another is to test the power supply with a PSU tester.

4) it only booted once after replacing the CPU heat sink and fan, did you put thermal paste between the cpu and heat sink? and did you make sure to plug the fan power wires back in?

also please post your system specs, power supply, motherboard, processor, mem, vid card.

1) no video. Nothing. But PC seems to Be working since fans are on and MB lights too
2) i took all the parts out, checked cable connections and started placing parts separately
to find if one of them prevented boot
3)Ill try to find another PSU
3)So that's what its called in english:P Yes i did put thermal paste and evrything is pluged since everything seems to be working. Except the monitor. But i have tried another one


Specs: ASUS P5N32-E SLI, 2x 8800GTs, Quad Core, 3x1GB RAM GEIL(5-5-5), Zalman cooler (dont remember exactly:P) and a 850w Silverstone PSW

EDIT: I have tested both VGAs separately too

ok, deffinately try another PSU, but to double check on placing parts in one by one, this part is quite important to do right or it may not work at all in finding a bad part.

when you do this, you should have minimal connections. to start, the only things that should be connected to the motherboard is the main power connector, the 4pin CPU power connector, 1 stick of memory, 1 video card, processor and heat sink/fan, and the power switch wires, nothing else, no cables, no wires, nothing. if you get nothing still, then hook up the other PSU and try it again. if it works, replace your PSU and then plug everything back in. if it doesn't work, try your other video card and a different stick of memory, still nothing, then most likely its your motherboard. but your welcome to try more memory and video cards.

I tested other RAM/cooler/VGA. Nothing. Since i dont have another "new" PSU to be enough to test even the basic parts(:P), and its kinda late to go out and get another one (11:30pm here) is there another way to test if my PSU is working? If not, then ill get back to u after i buy another one.
(it lasted 3 months...nice...:'''O)

Madcatz

only other way to test a PSU is with a PSU tester or a more difficult way is with a multimeter.

Squall5668

ok i tested the PSU to an old PC... just the 24(or sthng:P)pin cable. I dont know if thats enough but at least i know the PSU is not dead.
So that means i have to buy another M\B?

dai

did you apply the paste correctly

No i guess i didnt, after seeing this....:(
And to tell u the truth, 3 months ago, when i builded the PC i didnt apply it correcty either.
I always placed a bit in the center like i did with my older PCs with singe core...:(
Anyways i replaced it correctly, still no good... Dead CPU or Dead MB? I could get my hands on another 775 cpu to test the M\B. How possible is it that i just burnt my CPU?
(Note: Last time PC managed to Turn on, after i had cleaned it and everything
CPU was at 30-60 C all the time... even after "Test Drive" (Crysis maxed out, AAx2;))

dai

reset the cmos
turn the computer off
remove the power lead from the back
take the side off
remove the cmos battery
move the cmos jumper from pins 1 and 2 to pin 2 and 3 and the back to pins 1 and 2
replace the battery
put the side on
replug in the power lead
boot the computer
set it up out of the case on a piece of cardboard where you can get a good look at everything with
cpu
video
ram
speaker
and see if you can get post

i didnt exactly get ur point...sry:(
Have done some things u have told me i think
I havent reset the BIOS from the settings sice i cant even see the boot up screen. The MB doent have PINS for the jumper to Reset CMOS with it (EDIT:it has a place where there should be 2 pins and says CLR_CMOS, but no pins!). I Have tried reseting it by removing the power and battery and waiting 5-6mins and placing them back and tried again. It didnt work.
I tried that a couple of times actually. PC is opened up at my desk since yesterday morning (its 7am ATM and Im still trying :P)

dai

where it says clear the cmos touch the 2 solder points at the same time with a screwdriver it does the same as moving the jumper

still nothing....

dai

is it set up out of the case
check both sides of the m/b
check the slots
check the capacitors for swelling or leaking

I checked for all this and they seem fine...that was...time consuming xP
so... anything else in mind?...but i kinda getting desperate xD

dai

try booting with either the ram or video card missing and see if you get the bios error code indicating it is missing
no bios beep suspect the m/board

Plus no "5 beeps" when i tried booting without RAM to show RAM problem
And i have tried both VGAs separately
So its MB? Or CPU? The differance is that CPU costs Double and i cant afford them both atm in case im wrong.


Update: When i unplug the power from a VGA without taking it off the M\B
i can hear the Beep of hell...(:P)
So M\B is working? In that case... what the #$%^ is the problem? :'(
