Computer won't turn on, only fans rev

[QuinnJosh]

at first my computer had the same problem, fans would only rev. i took it to best buy they said "motherboard is shot need a new one". so i went on new egg bought a Biostar H61ML motherboard, Zalman cnps9500, Logisys 575W power supply, and 8g of Kingston ram. Installed it all, turn on the computer and then BAM, same problem as before. at this point all i have left to replace is my intel i3 processor or my hard drive so im at a lose here.

Remove the motherboard from the case and try to run it only with one stick of memory and a monitor. It should start posting. If not, replace the CPU. If it shows something on the monitor the motherboard was shorting to the case. Make sure you only have standoffs where there are mounting holes on the motherboard, and remove any others

my power supply's fans wont even go on didnt even look like anything happened when i removed everything but the power cables and one stick of ram

 

[Tmagic650]

The computer's power switch must be connected to the motherboards front panel header in the proper place to enable the power supply to turn on

 

[QuinnJosh]

what i saw when you said that ことは、性交何です

 

[QuinnJosh]

ya the removing the motherboard didnt do anything so im guessing i need a new processor?

 

[Tmagic650]

Yes, as you said, the CPU is the only thing left to replace

 

[QuinnJosh]

i got my new CPU an Intel i7, and when i put it in and started up the computer it will turn on correctly but after about 3 sec it will turn off. i dont know if its due to shorting or not

 

[Tmagic650]

Did you make sure you connected the 4-pin AUX 12volt connector to the motherboard near the CPU socket?

 

[QuinnJosh]

yesh it is everything is hooked up

 

[Tmagic650]

Did you remove the motherboard to install the new CPU? If you did, recheck the mounting screws. They should be snug but not too tight

 

[QuinnJosh]

ya, it seems like im missing 2 screws :[ does that matter?

 

[Tmagic650]

So you did remove the motherboard? Screws should be located where there are mounting standoffs under the motherboard, and make sure there are no standoffs where there are no mounting holes. 2 missing screws should not hurt anything

 

[QuinnJosh]

ya the screws seem to be fine, im at an absolute lose here Doc do you want me to post pictures so you can have a look yourself cause at this point idk

 

[Tmagic650]

So you have the same problem now that you started with? Where are you located in this World? What country? How old are you?

 

[QuinnJosh]

lol no not the same problem but damn close to it. my computer turns on now but only for a short while fans dont rev for ever :|

 

[Tmagic650]

Are you here in the USA? Try another case or power supply. I have seen a power supply that was shorting 115 volts to the case. The computer acted like yours

 

[QuinnJosh]

i need a new case T-T and yes USA, now what happens if the case doesnt work work and is there a way i can check for sure its shorting?

 

[Tmagic650]

The normal way to check for shorting is to run the computer with the motherboard out of the case, with a piece of cardboard underneath to protect from shorting again. Haven't you already done this?

ty

ty so much for all the help you've been once i got a new case the problem was solved it came with the little motherboard risers and that might have been the quick fix. anyway computer is now working perfectly. only down side was that i had to do a full restore but it didnt so too much :wave:

 

[Tmagic650]
