Optiplex 390 slow with Win 10

I have an Optiplex 390 with 8 gigs of RAM and it is annoying slow. I don't have may applications installed (just office and some printer software). I know the machine technically doesn't support Win10 but is there anything I can do to speed it up?

Re: Optiplex 390 slow with Win 10

Yes it is 2nd gen Sandy bridge cpu and chipset, significantly slower than 8th gen cpu, but faster than even older core 2 duo, which still supports Win 10.

if you have an i5, upgrade to top cpu of i7 may help a tiny bit.

if you have hdd, upgrade to sata ssd will speed up boot/restart significantly.

re: the machine “technically” doesn't support Win10.
chronologically machine was originally marketed for Windows 7.  Its hardware supports Win 10 64 bit natively.

Will the SSD upgrade improve general performance or just startup/restart speed?

Re: Optiplex 390 slow with Win 10

SSD would not help single threaded processor performance.  8th gen cpu has a much higher cpu benchmark score than 2nd gen.  2nd gen is not bad for email and surfing internet.  In my experience the slowest part of Windows operation is when it does automatic update or some other background tasks that you don’t even know, which can slow down front end task. 
check task manager/performance for cpu/ram usage %. If they are close to 100% during slow performance, you may consider upgrade them.

Also, I have an i3-2120 CPU @3.3Ghz

No wonder. Upgrade to quad core 2nd gen i5/7 if you still want to use this pc.  i3 is dual core.  You are basically running a pc not much better than core 2 duo.

@redxps630 Thanks for your help. Glad to know the i3 is the issue. Where does one fine a 2nd gen i5/7 these days?

Re: Optiplex 390 slow with Win 10

on ebay if you see a good deal.

i5-2500.  

i5-2400

i7-2600

if your stock heatsink cold plate is aluminum, you will probably need to get a copper cold plate Dell OEM heatsink because i5/7 TDP is 95W higher than 65W of i3.

One of the differences between the i3-2120 and the i7-2600 is 3.3Ghz and 3.4Ghz with 3.8Ghz turbo respectively.  The main difference between these 2 is the quad can handle loads better.

I'd still try using an SSD first.  It's the easiest bet.  It does speed things up, not just boot times.  Whether you try SSD first or second, you'll get the most notable difference out of the SSD.

I went from dual to quad in my previous 755.  Game-debate showed me 64% improvement between the CPU's.  I didn't notice much difference until installing and SSD.  They really do breathe new life into older machines.

If your 39O once worked quickly with Win10 and later slowed down, it sounds like it's time for a reload anyway.
