Turn on...3 seconds.. turned off.

**Blood_Luster** · March 6th, 2005, 08:29 PM

Hio, I have no idea what the problem is, possibly the processor? But basically last night my computer randomly turned off. I tried turning it back on, it will last for about 3 seconds, then turn off. I've checked all cables to make sure they are in, I have tried to unplug each CD-Drive and HDD, switching back and forth, nothing works. Someone told me it could be the prossesor, but I've yet to try to use my older AMD 2100 on it.
Current specs:
Win2k3 and WinXP Pro
DFI LanParty UT2K
AMD 3200+
Vigor400 PS
nVidia GeForce 4 Ti4400
512 DDR Ram (? could also be a problem, because it's slowest of the DDRs)
1 WD 80 Gig
1 Samsung 80 Gig
1 Pacific Digital 52X DVD-R/RW Drive
and 1 No-name POS cd-rom drive that can't believe still works.

Thanks guys, hope someone can help.

Is the fan still spinning on that CPU?

First thing to do is remove the old cdrom... and clean out all the dust, leave the side off for now and see if it will boot..
if that does nothing, unhook the slave drive... anything yet?
are all the fans spinning, PSU included?

Then use someone elses computer to make a bootable memtest disk and see if it will boot from the disk long enough to run the memtests...
if none of these things work, you may be looking at a new PSU

try just running the cpu, mem, vid card, hd..... see if it boots up...

Yeah, JP made a point I noticed right after I posted - was that power supply pulled from a dumpster or something?

**RetroEvolute** · March 6th, 2005, 08:39 PM

Yeah, did you try overclocking anything by any chance?

wouldn't say the psu came out of a dumpster....

could be a couple of things... need to start with the basics... like i said, start it with just the basic things needed to boot to windows....

Sounds to me like the power switch is shorting out. If you can trace the wires that hook to the motherboard and take them out. And then short the 2 pins that the power switch connects to you can eliminate that problem if it is in fact a problem.

Well your "VIGOR" is a pretty good suspect... 17Amps on the +12V?
Thats pretty weak for a 400watter...
This looks to be a generic MGE rebadge... this looks like alot of the junk "included" PSU's they slap a led fan on and give away in a case.

my bet is the psu also!

**skeltonjoe** · March 7th, 2005, 10:42 PM

psu or put the stock cpu cooler on it

I'd also say the PSU. I've had this happen before when a PSU's reactive componentes become discharged. try leaving it plugged in for about 24 hours without turning it on and then try it. Just a thought...it wouldn't necessarily explain the first time it turned off. Since it doesn't cost anything, it couldn't hurt though
