Hi all,

I'm in a bit of a pickle with a friends system, I have done all the trouble shooting I can so far, tested the psu, gpu and both sticks of ram.

First of all what is happening is when I power the system on the psu and CPU fans both spin up for a split second, then it all goes off, what is strange is it keeps doing it without me pressing anything, so every 6 seconds it tries to spin up and start.

Like I say I've taken the gpu out, tried each stick of ram, no hdds and I have re seated the CPU too. Is there something I'm missing or is it simply a faulty mobo? Also I've taken the full system out and tested it on a bench making sure there are no shorts.

Regards, Dane
 
Noise as in mobo bleeps? No, it doesn't get that far, the only noise is the psu and CPU fans spinning up. The psu is the newest part, he bought it a week ago and apparently he had the issue before then.(side note, the psu he bought is a shocker, I've talked him in to buying a unti from ocuk so should be ok in a couple of days)

Gutted as I sold my rig today so I don't have a spare psu to test the rig with.
 
Well from that its either a case fault like Stu said, a naff PSU (not enough power), a naff connection between mobo and PSU.

Out of curiosity, whats his specs?
When I had a cheap 500w PSU and added my HD 4830 (low power) it wouldnt turn on from time to time and buzzed all the time it was on.
 
Specs are:

Gigabyte ga-965p- ds3
Intel e6400
2 x 1gb corsair xms2 800MHz
Alpine 500w psu? New
Gpu is 7950gt but that's not plugged in.
 
Thats a cheap make (unless theres 2 Alpine companies in the PSU making business?), but it should be able to at least power it up, unless its knackered from the start.

Before he goes spending money, go nab a PSU from any PC (ask on here for any locals that could lend a hand).
 
another problem with the psu is (i dont know how much he paid) but it seems to have a lack of connectors on it, no pcie, about 4 molex and 2 sata, ive told him to buy either a bequiet one, corsair or a new lepa one, around the £40 mark, im going to get him a 4870 or similar for his new build so ideally it needs to have 2 6 pin pcie connectors.

just weird to me how a 500w psu doesnt even have 1
 
Yeah thats a cheap and nasty PSU, as you see with the lack of common connectors.
Get that out before it kills anything, even a second hand unit would be better than that.

Report back when you have a new PSU/ tested it with another PSU (preferably a well know branded PSU).

I too, think the PSU is what's causing the problem. Get a corsair PSU, you won't be disappointed.

+1
Ive had the same HX620 for the past 2 years-ish, but only put it in my build this year. Still pulling strong with no odd sounds, vibrating or dust (dust filter over fan).
 
Update for you:

i got new system parts today, a sempron and 4gb ddr3, put the system together and it turned on fine, so it wasnt the psu, i connected the 2 250gb hdd's he has and what happens next? lots of smoke and burning!

i had to lunge to turn it off before it went up in flames. so now thats 2 x 250gb hdd's fried, im guessing this was probably the cheap psu? i have an old 120gb ide drive ive put in and all is working well now, ive installed win7 and installed the old gpu.

next im buying a 4870 for it and ive talked him into buying a new psu.

i have decided on either the bequiet 530w (i have had this and its great), xfx 450w, corsair builder series, lepa 500w W-series. what would you suggest, bearing in mind we will need a minimum of 2 x 6 pin pcie connectors for the gpu.
 
Ouch

Never go for supercheap PSU's - I've always used OCZ PSU's and had no problems.

At least you only lost 2 cheap drives it could have been much worse.
