Hi.

I have an old Dell Dimension 8300 desktop that I've been trying to keep alive for budget reasons. I've added several component upgrades including new graphics card, memory, HDD, audio card, and optical drives.

I wasn't having any problems, but I decided that it would be a good idea to upgrade my old stock Dell 250w PSU for something a bit more powerful to run all this stuff. I bought and installed an Athena AP-MPS3ATX40 400 watt unit. Everything seemed to run okay but now and then when I run some of my graphics intensive apps (Photoshop or my video editing software) the screen will freeze and I'll end up having to manually shut down and restart. Event Viewer doesn't show anything abnormal. Never had this problem before the PSU upgrade. I'm hoping that I won't end up having to put my old under-powered unit back in the machine...

Any clues would be greatly appreciated. Here's my stats:

Well, if they just started after installing the PSU and it ran fine before then I would recomend RMAing the PSU for a new one and see if that solves the problem, and putting the old one in while your waiting.

Recheck all of the power connections.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

Thank you for the replies.

I opened her up and re-seated all the connections- I was particularly interested in the connection to the video card. It may not have been fully seated. So far, so good.

If I do end up returning the PSU, should I look for something better to exchange it with? Could someone recommend a good one from a reliable manufacturer that would work with my machine? My stats and my present PSU are in my op.

Thanks again!
