Does this sound like a PSU problem?...

[mcast12]

Slapped in an Athlon 2200+ (from a 1400) into my A7V266 (after upgrading the bios to 1011), turned it off and powered it back up again. The CPU fan sat there spinning but nothing else happened, couldn't even get into the bios. I then reset the cmos thinking the settings were messed up, again nothing. Disconnected everything except the graphics, one memory stick and the keyboard, same thing, CPU fan spinning, mobo light is on, nothing else. Then I'm thinking mobo is fried, so I bought a new mobo, same thing happened. Played with a bunch of settings and cpu/mobo combos nothing worked. Finally, I played with the jumpers on the new mobo and got into the bios!

After a lot of trial and error I got the entire system running at a lower clock speed (1100), but the whole system shuts down any time I play a game i.e. stress the CPU

I'm thinking its either the CPU/mobo temp (bios reports it as around 31degC for CPU imo thats low) or the PSU (300W) not having enough juice.

Anyone experienced something similar?

This is probably a power issue. I was using a 350 watt psu when I upgraded to a soyo dragon mainboard and an athlon 2200 plus, and I was lucky to get one or two case fans spinning with the thing powered up. I suggest going for a 420 watt, It should be more than you need for quite some time.

If your supply can't provide what AMD recommends which is a minimum 30-amps on the 5-volt line and 180 watts on the 3.3 and 5-volt lines combined, you are likely to have problems. The label on your powersupply should tell you what it's rated it. Many name brand 300-watt supplies are rated for that, most no or less known brands are not.

Thanks for the comments.

I'm using a non-branded 300w PSU, not sure if its rated or not, either way I'm going to buy another.

Can someone recommend a good 400+w PSU from a site in the UK? Also, I'm probably going to buy a good case, are the aluminium ones worth it? any idea which one?

I've experienced quite similar problem a few days ago. All I did was adding a CD-RW and DVD-ROM drive to my Athlon 1200, with abit K7-A. As a precaution I bought a new casing with 350W PSU.I turned it on, the fans were turning, and that's it. No bios or anything else. Same as mcast12 the problem solved when I bought a new mobo and proc (an intel one, shamely).

What I want to ask is, can I still use the old mobo and proc? Or are they really fried?

Thanks a lot

Mike I don't think either of my M/Bs or CPUs are faulty, I honestly believe its a PSU issue. I'm going to try my new PSU when it arrives on friday. I'm willing to bet your athlon and M/B is ok.
