Solve : recently upgraded my parts, computer won't boot? |
|
Answer» i've been acquiring the parts to upgrade my system and finally pulled them all together today and installed them, the most notable change being swapping out both my motherboard and cpu, and now my computer won't even start. I followed all the directions that were included with the motherboard/cpu and supplemented them with a how-to that i found online. I have double- and triple-checked all my connections and everything seems to be sound. when i plug in and turn on my psu, the green SB PWR LED on the motherboard lights up, indicating that it's getting power, but when i go to turn the computer on my cpu fan and rear fan start to spin for a split second and then stop and NOTHING further happens. the connectors for the power switch and the reset switch on some ASUS boards are fitted with a pin space between them, it is often overlooked when pushing the connector onto the pins, I have seen a few where they were placed close together, worth a check. yes, i have fitted both the 4 pin connectors for the mobo and gc. and i don't have a reset switch/connector on my case so there is only the connector for the power switch.Did you recieve standoffs with the MBoard ? ? These are little brass posts that make sure the MBoard is not contacting the case anywhere preventing a short. If not they can be bought at any computer store. It sounds like you have been patient with this build and taken some good advice so hang in there... BTW What beeps if any or just a 5 second shutdown ? ?my case actually has standoffs built in already to keep the board raised off it. there are no beeps at all. when i turn the psu on and then hit my power button both my cpu fan and rear fan start to turn and then stop and nothing more happens. if i try pressing the power button again without first turning the psu off and BACK on then i get no response whatsoever.Do you have another PSU you can TEMPORARILY swap in there to see if this is the issue ? ? The one you listed seemed to get good reviews so i'm not convinced it is the problem but you never know. Also did you remember to use thermal compound/pad when assembling the CPU ? ?Sometimes a simple, but often overlooked mistake, can cause this. Check the connections to the power switch and make sure they are not reversed. Quote Do you have another PSU you can temporarily swap in there to see if this is the issue ? ? well, i just hooked up my old psu and it booted up, let me go right into bios, does this mean that my new psu has been the issue all along? my old one does not have the power capacity to sustain my system so i know that it can't be a permanent answer.I would have to say yes...if the old one booted it up properly first time even though it is under-powered then yes it is the newer PSU at fault. Be glad it didn't take any components with it. It could also be that you missed something connection wise that you got right with hooking up the old PSU. Review all your steps to be sure, but my money is on sentence 1ok, patio, so i have another question. i have not tried connecting my newer psu back up with my old mobo to see if that still works, but is it possible that it's simply one of my connectors that's at fault? honestly all i did when i used the older psu was hook up the 20+4 pin and 4 pin connectors on the motherboard so could it be that either my new 20+4 or 4 pin connector simply does not work? thanks for all the help by the way You're welcome for the help. On the new PSU check inside both the 24 and 4 pin connectors to make sure none of the connectors have been pushed back out of place. alright, so i got up this morning and checked my psu connectors, the 4 pin LOOKS fine but i noticed on the 20+4 pin main connector that one of the pins doesn't have a wire running to it, naturally, i was all like "aha! that's gotta be it" and was going to take a picture and post it here. however, i went to the newegg first and found this: http://www.newegg.com/Product/ShowImage.aspx?Image=17-128-001-01.jpg,17-128-001-0.jpg,17-128-001-03.jpg,17-128-001-06.jpg,17-128-001-07.jpg,17-128-001-08.jpg,17-128-001-09.jpg,17-128-001-10.jpg,17-128-001-11.jpg,17-128-001-12.jpg,17-128-001-13.jpg,17-128-001-14.jpg,17-128-001-15.jpg,17-128-001-16.jpg,17-128-001-17.jpg,17-128-001-18.jpg,17-128-001-19.jpg,17-128-001-20.jpg&CurImage=17-128-001-09.jpg&Depa=0&Description=HIPER%20HPU-4B580-MS%20ATX12V%20v2.2%20580W%20Power%20Supply%20100%20-%20120V%20-%20Retail which left me a little confused. the 20+4 pin connector on my old psu does not have this completely empty pin; the CORRESPONDING location on that one has a white wire running to it. anyone know what this might signify? i mean if they show it in the product picture then i have to assume that the product is supposed to be like that, but this seems to me to be the only physical difference between my two power supplies edit: now i've gone and looked at some other psus and noticed the same thing with the 18th pin being open so i guess that can't be ithey patio if you're on i have another question, is it possible for me to mix and match my connectors to try and isolate which one is the problem or is that a no-no? (it kind of sounds like a no-no to me but i wanted to check) i.e. 4 pin from old psu with 20+4 pin from the newer psu and vice versa i am emailing hiper to see if they would know of any reason why it would not be working and in a little bit i think i am going to reinstall my old mobo/cpu/vcard and see if it will still run with those.I wouldn't experiment with hooking up more than one PSU on a new build. I might have to dig out a dinosoar old build to see if i can create some blue smoke now that you've got my interest though... p.s. Ask Hiper what their return policy is...you might get lucky !lol, i appreciate it, just don't explode yourself |
