You mean 5150?

 

Yes you can use a standard ATX PSU as long as it is 350watt or higher

 

Do some troubleshooting first

Don't Do Anything Yet, In my Experience not PSU Problem

see my post on yesterday

Thanks for the replies.

 

The light is solid green but the PSU is making a buzzing noise and the memort faliure lights are lit.

 

So I was thinking it was either memory or PSU, was just double checking you could use a standard PSU incase I need to buy a replacement. According to the troubleshooter it could also be the graphics card, so I'll check that too.

 

 

Turned the PC on today and it booted as normal :smileyindifferent:

 

Only thing is at the front where the lights are, the battery (at least I think it's a battery) light keeps flasshing evey few minutes. I can't see anything about it on the troubleshooting page, so does anyone know what it is?

Right, so it clicked off before and now wont come back on.

 

It's making a buzzing noise but not coming on at all, no post beeps, nothing. The power light is solid green, the three and four lights are on (according to the troubleshooter this indicated memory faliure, but the PC has been working fine all afternoon) and there's a small light that looks like a battery flashing.

 

Can anyone give me any advice as to what could be the most likely suspect?

 

PSU?

Graphics Card?

Memory?

CMOS battery maybe? (Which type of battery do I need to replace this with?)

Motherboard? 

 

Obviously the memory is easiest to check, so I'll do that tomorrow (It's at a friends house and worked fine all day whilst I was there, then stopped working an hour after I left) . But I don't really have the cash to buy spare parts and test which is the faulty one. I'm hoping to try and norrow it down as much as possible before buying any replacements.

 

So any and all advice is greatly appreciated.

 

Thanks.

"the troubleshooter this indicated memory faliure"

 

I think this is your clue. If you have more than 1 memory module installed, remove one, if no change, swap in the other module.

Thanks. I will try that tomorrow, but the buzzing noise worries me. I've never known faulty memory to make a buzzing noise.
