I need your opinion on a big problem with my pc - help please!

[gamingguy27]

Hello,

Well, motherboard went a bit funny (turning off randomly, not detecting IDEs etc), so I returned it.

Brill, worked fine for a day... left the pc on for about 1 hour then it turned off and it refuses to turn back on for over minute (if at all).

Ive changed the gfx card, no luck.
Ive changed the ram, no luck.

I have a good PSU and a brand new motherboard.

Weirdly enough though, if I turn the pc off at the mains for about a min the PC turns on (as per usual) then decides to crash somtime between the windows loading screen and my desktop. But after a crash it simply does nothing if you try and turn it on (blank screen not much noise, no HDD lights).

I really dont understand as everything has been working fine, and ive tested everything but the CPU which I think may be dead (but its still in warranty so thats fine).

My Specs: (latest firmware and drivers)

Brand new Abit NF8-V
Amd64 3400+ (1.55V defualt not oc'ed)
1 x 1024 Crucial pc3200
1 x 512 Crucial pc3200
1 x Seagate Barracuda
1 x Maxtor Fireball
1 x LG DVD-ROM
1 x LG DVD-RW
1 x 6800GT

Hiper Type-R 480W PSU with 12V+ @ 34A

Thank you for any help!!

Remove everything except 1 stick of memory and the graphics card, oh and your bootable HD then see if it works, if so add the other components back in 1 at a time until the fault occurs.

If it doesnt work then one of the items is intermittently faulty, it may also be your PSU, if you have a spare try that.

very mysterious

I have two questions: why are you mixing ram?
where did you get that power supply.That might be your problem
if its not a reputable company, they tend to lie on their product's ratings

I would agree the problem is most likely your PSU. and NO, hiper is not a Good PSU. try another PSU if you have access to one and see if that solves your problem. or spend about 10-12 bucks on an Antec PSU tester.

Hmmmmm,

Thanks for the help you guys, I was really hoping it wouldnt be the PSU but it seems that it is.

I unplugged everything but the essentials and my pc, so far, hasnt turned off.

Allthough im getting appauling performance with only 512

Cheers people, i'll be getting another Hiper PSU as its still within warranty.

Out of interest, why would a PSU after a year of stable use, decide to go downhill?

Cheers again people,

Alex

Because it is not a quality PSU, the same reason why it could new, rigiht out of the box fry all your computer components if it fails.

Here are lists of good and bad power supplies:

troubleshoot power supply with multimeter:

Also, you can google info on how to test your own power supply with a multimeter that you can pick up for about $10 US. If you go to techrepublic.com there is a very good tutorial there with pics. You can use screen capture to make a copy of it. You have to register but its free, a great site, and they dont bug you.

example of good but low-priced power supply (if its still there). Look for Fortron, Antec, enermax :

This is the $25 to $50 range.

As already stated, poorly built power supplies (ps) may run for a while but then they die before they should. The worse thing is that when they do die, or when there is a power at the wall issue, these ps's not only go bad but they take other parts of your pc with them. When a good ps gets hit bad by power issues at the wall, for example, they have circuitry inside them to prevent problems and if they do go their circuitry is built so that your other pc parts dont get damaged!
Hiper, if i recall, is not a good ps, sorry to say.

Maybe your issue is more the first problem, where you should zero write the hard drive as it seems your ps isnt that bad:
Using "Hiper Type-R 480W PSU" in google, i see fairly good reviews of this ps.
Could be you just need to return yours and get another one under warranty, if you can.
