[resolved] Computer starts... for 1 second then shuts down

Moridin333 · 04-17-2005, 08:59 AM

I got a new mobo and cpu and video card from my girlfriends dad. My girlfriend already had a crappy computer so I put the mobo, cpu, graphics card, and sound card in the old case.

Turned it on and got power for one second. Then the power shut down. I had to turn off or unplug the power supply for a second to test it again, because it would not start.

I have unplugged everthing with same results. I've used a different mobo and a different cpu and a different power supply with same results.

Any ideas?

Difficult to tell what exactly the problem is without knowing what components your talking about. Could you list all the specs as detailed as possible ? CPU, RAM, Mobo, PSU etc...

It sounds a lot like a short (did you use motherboard standoffs and made sure none are in the wrong spot ?) or the power supply isnt sufficent. You said you used an "old case" - how old ? Did you replace the power supply to accomodate for the newer components ? If not than thats more than likely your problem.

Yea sorry about that, my specs are
Cpu AMD 3200+
Graphics GeForce 5200 FX (i think)
PSU Generic 350 watt (also tried a generic 300 watt)
MoBo Biostar M7NCD
Ram Generic 256 (1 stick)

I know it's not a short because I got sick of pulling out and putting stuff back in the MoBo's. I have them laying on the kitchen table on some cardboard and am using a flathead screwdriver as the on switch.

The thing I don't under stand is that I have used a different processor, MoBo, and PSU and the same thing happens on every combination. I guess the mobo could be fried and it screwed up both of the CPUs, or vice versa.

And what was the other motherboard and CPU you tried ?

MoBo Biostar M7VIP
Cpu 1600+

Hi,

I would like to tell you that if you don't have a short and have to assume you don't since you have built it out of the case, that you need to get a REAL power supply. A generic 300 or 350 will not pull this unit. You have a CPU that is power hungry, a Video Card that takes loads and loads of juice and a generic generally will not begin to pull this. If it were an Antec 350 or an Enermax 350, then maybe.....It has to be from your troubleshooting either a power supply or a bad stick of ram. Oh, generic ram is always suspect in cases of this type. Really, back on the power supply, you should have a 450 watt power supply (brand name) to do a decent job with this unit.

I agree with you completly about the RAM and the Power supply. But if all I did was take the parts out of one case and put them in to another it should at least stay on. I would like to eventually purchase upgrades for this computer but I need to find the problem first. I have used different Ram and 3 different Power supplys.

I begining to thing one of the motherboards killed both the processors I tested. Oh well. I'm trying to put the computer back to it's origional hardware, not the stuff her dad gave us. Then if I can get the chip to work in it great. Then if I can get the video card to work in it even better.

After that I'll probabbly save up for a couple of weeks and take it to a shop to get everything tested.

Okay I got it fixed

The MoBo I got from her dad was the problem.

I put the cpu, graphic card, and sound card in the old mobo with all the ram and it works fine.

Thanks for all the help.
