Computer turns on and CPU fan spins for a second or two but then shuts down

I was using my computer to make a bootable flash drive with ultraISO and I went away because it was gunna be awhile and when I came back it was done so I closed out the window and went to eat dinner and then came back again and this time the computer wouldn't turn on at all, I have tried taking out my memory, GPU, and my PSU. I recently replaced my old PSU with a corsair cx600 and also recently replaced my case and it has been working fine for little over a month since the new PSU, but now I am stuck and don't know what else to try to get this thing to work again because I do not have the money to build a new one and I like this system a lot so any help would be appreciated!

If it helps anybody my system is a Pentium Dual Core, 6GB RAM DDR2, NVIDIA PNY Verto 9600GT, Windows 7 Pro 64-bit, 1 Western Digital 160GB HDD, and a secondary Seagate Barracuda 500GB HDD, Case is a NZXT GAMMA, Motherboard is a HP/Compaq:Benicia-GL8E-(Asus IPIBL-LB) Micro-ATX.

is the flash drive still plugged in? try unplugging all disc drives and any secondary hard drives leaving only your main boot HDD connected.

Yes, i have unplugged everything possible for the computer, I unplugged DVD,both hard drives, and my graphics card. But it still wont boot. I just connected the main power connector and the secondary power to the board and my case lights up for like half a second and the CPU fans starts to spin but then shuts down and does not make any beeps or anything

It sounds to me like your PSU died, lately I've seen a lot of them taken out by brown outs and power surges. Also check the capacitors on your motherboard make sure they are not popped or damaged.

I hooked up my older PSU which is a lower wattage but ran that system for awhile and it wouldnt even turn on(i tested the PSU by putting the paper clip in the green and black wire spots and it does turn on), i just replaced the thermal paste to see if that would fix the problem but it didn't, i also took out all the RAM and tested it by putting one peice of it in at a time and that still didn't work. I checked all my caps and none of them blew because i had that happen before. Im thinking that the Power supply fried my Motherboard, does that happen somtimes?

A power supply can fry a motherboard. I have had it happen. The power supply went bad and took the motherboard and CPU with it.

I had a very similar problem with a P55-USB3 motherboard. The board itself was fried, and was stuck in a reboot loop without POST. Get yourself a decent power supply tester. If it's the PSU, replace it before it destroys any more of your parts. More than likely it was both your PSU and Motherboard which are damaged.

Uhhhh.....this sounds like PSU like others are saying...

Do you have a friend where you could test it? I once took a suspected damaged PSU to a computer store and they tested it for me.

Like others said it sounds like the psu. I don't think that it fried anything though. Corsair is making quality power supplies that have all the essential stuff to protect your system. If you can borrow another psu from a friend or a computer store/ tech. service that would be good to test it out. Best of luck.

I seriously doubt that the PSU would wreck anything if it went bad. I have seen boards wrecked by power fluctuations without harming the PSU, take a close look at the capacitors on your motherboard. If there are blown caps the board can sometimes be fixed by replacing them. boards that I have encountered with blown caps sometimes act just as you describe.

I actually already sent the PSU back to amazon bc it was still covered by the warrenty which is good because now I get another one for free, BUT bad thing about that is now I'm pretty sure that my board is toast and the CPU with it. And yes I agree with the PSU tester, I do have access to a very good tester and I did think about testing it but I thought sending it back was the better option so I can get another power supply before the warrenty ran out. So does anyone have any other ideas on how I might be able to fix this? I'm fresh out if idea's on how I would be able to do this. And also what causes a PSU to short out? Because I had a corsair which is a very good brand and it still burnt itself out

If your MB and CPU is toast, there is really nothing left to do but save up for a new build. And then have somebody knowable build it for you.

Okayy i guess then im gunna have to save up since it seems like its toast which sucks because i actaully just got this board for free. Something that may be important but i dont know, when i plug in my power supply and turn it on for the first time everything lights up and starts to spin but then shuts down, but then when i try to turn it on again for a second time nothing lights up and nothing spins. But if i disconnect it from the wall and take out the 24pin and P4 connectors and then reinsert them it will try to turn on but will fail again. Now i had another board that had some bad caps on it and even with those bad caps it would still try to boot and i could get into the BIOS and POST screens. But on this HP board i cannot, and i dont see any caps that have that werid brown stuff coming out of them anywhere on the board.

I had the same thing on two different intel boards, as far as I could tell it had something to do with not recognizing RAM. The board did the same thing with or without memory installed (the RAM was good I tested it on an identical board) when I connected power, fans would spin up and leds would flash then nothing. after many attempts it wouldn't even do that.
You should be able to save the processor if you want, I think you can find boards for the pentiums reasonably priced on e-bay.

@MXZ583, I will look
Into those boards on eBay! I found some resonably price haswell pentiums
On newegg so might go with that option but my new PSU should be coming either Tuesday or wensday and I'm
Gunna see if it works with this new one! I'll have to let you know if it works or not so we can mark this forum as a solved one! Thanks for the help!

So I received my new PSU from amazon and I plugged it in and it still wouldn't turn on, so I found another one laying around in my room and I tried that one and it turned on but the case fans didn't spin and then the power supply blew up and smelled horrible so I just threw it away so now I think the board is toast but I have no way to check the video card and the memory because that is the only board that is in my house that has DDR2 and a PCIe x16 slots

The memory and video card are most likely fine. the board probably just has a short somewhere that is causing the PSU to blow up.
It is possible that your fans are dead though.

Okayy!! That is good to hear! Im gunna take them to a friends house and test them out on his computer just to make sure that they work.
