Howdy all,
I had a old dell OptiPlex 755 with Win 7 64 bit. It was running on my home network. I used it for email and some web STUFF. Nothing really fancy. Anyway the POWER supply toasted and the system is down. I am starting to look for another machine. I could replace the power supply, easy fix, but I figure it's time to move up a little. Anyone know where I can buy a rebuild or something cheap. I would like to run windows 10 so it would need a little power.
 

THANKS for the IDEAS.
I have a 755 in my spare stuff. Actually, it is better than the machine I am on at this moment. The 755 runs windows 10 well.
IMO you should replace the power supply and keep it on hand, Sometimes you can pick up an old 755 on eBay for parts.  I see some PSU for the 755 under $20. So for $20 you can extend useful life of the755. I will give that a try. So a new power supply it is!

Thanks for your time

Well did a quick check and found one on amazon. Its $25 used or $50 new. Went used. No moving parts in these so it works or it don't. I will get it next week. I will let you know how I make out. If I crash and burn I will just say to h$ll with it and buy a new nicer system.

Just wanted to mention in case you want an UPGRADE if your running a lesser powerful Core 2 Duo you could upgrade to a better Core 2 Duo cheap.

Here is 755 CPU support list:

The Core 2 Duo CPU's with 4MB L2 Cache make a considerable performance difference.

I upgraded a system from a 1.8Ghz Core 2 Duo E2160 with 1MB L2 Cache to a 2.4Ghz Core 2 Duo E6600 with 4MB Cache and its so much better with the E6600 dual-core.

Sadly the motherboard I have doesnt support the Quadcore, but yours does. Quadcores come at a premium but are affordable.Thanks. I will look into this as well...

Well I finally got the power supply in and I installed it. The machine came right up and all is fine. I am still going to load Win10 on it later. Thanks for the ideas and help!
