second attemp at computer build..having problems again!!!

could be a bad power supply or mobo leaning towards PSU.
when it turns on does it make it out of mem test? Do you hear any beeps from the speaker? Do the case fans come on?

also if you dont have the power cable hooked up for the video card it will do that

My friend had the same problem! He pulled of the heatsink after putting it down for some reason, and never replaced the thermal paste. The processor was shutting itself down to prevent thermal damage. You may want to reapply thermal paste just in case.

i took out the cpu fan and spreaaded the thermal paste some more to see if it would help. same thing happened so i tryed using a different cpu fan but it just turns off...im geting no beeps or anything..i tryed booting it up with the graphic card unplugged and ram uninstalled but still the same thing..turns off after 2 seconds..

Wonder if you have your fan hooked up to the wrong on-board plug-in?
Although roswell is well known for its doa's....

im pretty sure i have it plugged into the right place...it says cpu fan..do u guys think anythings broken?

I would check the site, i have 3 fan slots that say cpu slot, but only 1 really is.

The first thing I would have checked is the power switch, make sure its not getting stuck.

That is exactly what it sounds like to me.

Do you have both cables from the power supply plugged into the motherboard? Plus the cable from the power supply to the video card. If so I would be leaning toward the PSU being weak.

take a snapshot of the system at decent resolution to show us what you got.

ill look and see if theres another cpu fan slot...but the fan for the cpu turns on when i push the power button and the power button seems fine..it pops up after i press it..and yeah i have all the power supply wires plugged in..i tryed booting it up without my graphic card but did the same thing to so im not sure if its my powersupply being to weak. how long does it usually take till it starts beeping? if somethings wrong?

other than your psu [never heard of rosewill] you seem to have a solid system,re beeps,,usually if there is a bios problem it will commence beeping at boot,you might want to try testing the mobo outside of the case start with just the video and 1 stick of ram and go from there,you need to try to isolate the source of the problem,check that all connections/power and data are firmly in place,and make sure that your psu has the required amps/volts,,some no name psu's do not deliver as advertised,there was a time when i had the same problem,turned out that the onboard battery was not fully charged,left it set for a while and presto no problem,don't think so in your case,not now a days anyhow ??...i had a similar problem with my present board also an asus,only it beeped at me took it back to the store ,,it worked fine,,brought it home plugged it ,,it worked fine,, go figure,,,BUT i pretested it before i installed it this time still working fine..  can you do the same??
the great advantage of buying locally is if things go snafu,well the store is only a bus ride away.....g'luck...

PSU... My guess, anyways. If you can test the PSU, do so. If you can't, try re-seating the plugs.


Just looked up G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400 on new egg. What pair do you have?

Also, none of these pairs has a particularly low voltage. I don't have any experience with this particular MoBo, so I have to ask... Is this ram compatible?

Check power supply connections to graphic card
Check DVI connections to both graphic card and monitor
Check power supply and data connections to your HDD
Make sure keyboard and mouse are connected

Check power supply connections to graphic card <<< Ok.. Sure. This might actually be an issue

Check DVI connections to both graphic card and monitor <<< Smoke crack much? You can start a computer without a monitor.

Check power supply and data connections to your HDD <<< Again, this won't keep it from at least posting.

Make sure keyboard and mouse are connected <<< Again, this won't keep it from at least posting.

what?

Take the motherboard out of the case, lay it on a flat surface next to the case with piece of cardboard under it. Start with only 1 stick of memory, the GPU and the CPU with the heatsink. Hook up the power and your monitor, see if you can get it to post from there. If so, remount the board, and try again, if it posts, start adding 1 thing at a time.

Best advice given so far. I would add this though. Make sure you don't build up static electricity and shock the components. Keep touching something to ground yourself.

^Agreed.

@OP: It is 90% likely your PSU. Those Rosewill PSUs are cr@p. Get a top tire PSU listed here:

I recommend a Corsair 520HX or PP&C 610 or better.

Double Chech please you are loosing anything
I'm almpst sure it is a connection problem
If it was me I'll disconnect everyrhing and even remove memories and all cards and redo all
I'll try also the memory sticks in different Dimms

Use a hammer on it if all else fails. Show that thing whose boss!

i rechecked all wires...took it out of the motherboard and laid it on flat surface with cardboard tryed booting it up still same thing...tryed it without the cpu or graphic card same thing...do you guys think its more likely my power supply that i should replace first? since it doesnt boot up even if i have my ram in or out..

Take your time.
Read your motherboard manual.
Read this if needed http://www.pcmech.com/byopc/.
Try what jitpublisher says.
Borrow a friends PSU, thats probably the problem. If so, get a new one from Shadow's list tier 3 or better depending on your budget.
Have a another computer up, so you can ask the forum questions, as you build step by step.

I have had this type of deal with PSU's in the past. Really, this is the first thing you need to check.

i just went and bought a new powersupply. but it still does the same thing. agi powersupply that is 580 watts...this time i just pluggged the power in and nothing else but still does the same thing turns off after couple of seconds..how much do shops usually charge to test things like this out? would it matter if im missing one standoff? in the middle of the board?

did you clear the cmos? Also, does your board require any bios updates to accept your CPU? Shops vary... 45 bones wouldn't be out of the norm. What town you in?

i dont know how to clear the cmos and the computer doesnt even start up enough to be able to do anything. so i cant update my bio. im from eau claire

Is it possible that when he fried his motherboard the first time that he could of damaged his cpu if this is the same cpu from the 1st attempt?

i bought new motherboard and cpu and power supply and graphic card...ram hard drive and dvd drive is the same...any ideas on what could be wrong? it doesnt even beep when i turn it on without cpu in..i just have the main power plugged up to the motherboard and nothing happens.

Ok.. so the CPU is the same as from the first attempt. Take it to a shop at this point. Let them test the components. They would be able to test each piece individually.

the cpu is new...but i guess im gonna have to take it to the shop and have them test it out.

Keep us posted on what the problem was when they find out. I'd love to know because I was totally betting on a PSU issue.

P.S.
use this thread because I will have it bookmarked.

did you ever clear the cmos?

i would reseat the CPU. I laughed at a buddy of mine when he didnt mount the fan all the way and when he put the tower upright it would boot for 3 seconds then BAM! the freaking cooler fell off. Make sure everything is good with the paste and cooler.

You need to listen to people and buy a quality power supply, not replace a weak link with another weak link. Either that or buy a Dell computer because if your not going to take the time to read a manual to at least learn how to clear CMOS then there is no helping you.

Ease up on him. Let’s see what the shop has to say. He may have done everything well and just have a bad MoBo.

i bought that power supply cause the guy at the shop recommended it and i didnt wanna order one and have to wait a week to get the new one. i reseated the cpu and tryed the other cpu fan but still not working..ill try figuring out who to clear the cmos and if that doesnt work then ill take it to the shop tommorow

Make sure you are plugging in the 20/24 pin power connector, the cpu fan connector, and the 4/8 pin cpu 12 aux connector. My quess is you over looked the cpu aux connector.

read the whole manual book and couldnt find any info on clearing the cmos..anyone done it before on this motherboard?

Does your board need a second power connection? Look carefully in the manual. If you miss that second one, it will act like yours is acting.
Don't get discouraged everyone here will help you.

its a 24 pin motherboard so i just stuck the 20 pin and the 4 pin in

Usually a jumper to short (make sure it doesn't stay shorted) and a battery to remove. Mobo manule should have it pretty clear.

Without looking at your PSU/Mobo.. I am having some issues with what you said. Some PSU's have 20 pin+4 pins for the main power. Then they have a seperate 4 or 8 pin plug from the PSU to the mobo for the CPU power. So... what you running here? do you only have a 20 pin out from the PSU for the main power and you plugged the 4 pin CPU power in with that?

have to move over to the pic of the board laying flat

http://www.newegg.com/Product/ShowImage.aspx?Image=13-1... Your mobo needs the 24 at the bottom of the picture along with 4 pin at the top right.

i didnt plug the 4 pin in..do u think that could be the problem

Exacty! Just like I said. That other 4 pin is for the cpu power and you cannot run without it. If your PSU is only 20 pin it it will still work, but you must have something plugged in both spots.

didnt see that pin...i got it to turn on without dieing but now i got a blank screen..my monitor doesnt turn from orange to green...everything seems to be turned on but im not sure if my graphic card is working..is it supose to beep when i turn it on? and it didnt make any noises...what do u think is wrong now?

i went and got my friend's graphic card to test if it was my graphic card or something else but the same thing still happens...i took out the ram i had in and turned it on to see if there would be any beeps but still nothing..

When you make hardware changes you need to reset the cmos for the changes to take effect. If you didnt reset cmos then it might still think the ram is in. Do you have the 4 pin and six pin aux power cords plugged into your graphic card?

Use one stick of ram and make sure you have the 4 pin and six pin power plugged into the graphic card. Reset the cmos with the PSU unplugged. Plug PSU back into wall and try to boot.

It might need dual six pins it looks like on newegg. What ever power the card requires plug it in.
