Hi,
I looked up your system, and my experience so far has been that the Dell XPS systems I've attempted to upgrade to W10 have all worked so far. That's not to say that they are not without issues once the upgrade has been completed; especially if you are attempting to update to the latest Anniversary Update (AU v1607 Sep. 2016; there are 3 of them). As far as your hardware goes, your machine can have either an i5 or i7 processor probably 3rd gen or later. Your machine service manual is dated Dec. 2010; which means your system is 5 years old coming up on 6 years old. According to Microsoft W10 will work on any computer hardware manufactured in 2009 or after which they consider to be a
"modern-era computer". All of my personal home computers are 2008 or older except one about the same age as yours; which all took the W10 upgrades (I have 5 machines so far). I've done a couple newer than 2010 and those as you would expect also all worked. I noticed too that your Chipset is an Intel H67, which I haven't done a W10 upgrade on specifically. Based on your CPU chip though I'm not aware of any issues related to your Chipset or CPU chip.
There are 2 issues facing you here. The first is whether or not to attempt the
BIOS upgrade to "beef up" your Mobo hardware so to speak. This is always a good idea, unless you've never done that before.
WARNING: FLASHING YOUR BIOS IS AN EXTREMELY HIGH RISK PROCEDURE AND SHOULD ONLY DONE BY TRAINED PROFESSIONAL TECHNICIANS!! ATTEMPTING TO DO THIS IF YOU'VE NEVER DONE IT BEFORE CAN BORK YOUR MOTHERBOARD, AND THAT'S A $175-$1500 REPAIR!! If you don't care about this computer, as it's a secondary machine to your other computer which you use regularly, then you might attempt it, though that's against our advice.
If you've never done it before, take it to a licensed professional computer technician in a reputable computer repair shop or large computer chain repair center such as Best Buy Geek Squad and pay him to do it for you. Reinstall your W10 and retest. Even though Dell doesn't have
OFFICIAL W10 driver support as mentioned by Norway, it could work.
I have several machines here running W10 that don't have official W10 driver support from the manufacturer--yet I have them working.
The 2nd issue you have is that whether your do the
BIOS update yourself or you pay someone to do it; there is no Guarantee it will work for you!
As both Norway and kemical mentioned,
the safe thing to do is to stick on W7 until 2020 when Microsoft end-of-life's W7. Using it beyond that date is like using an XP computer now after 2 years of Microsoft non-support; it has become a major target for hackers, cyber-thieves, and cyber-identify-theft criminals, so you could just junk that computer at that point or recycle it or unplug it from the Internet and use it to play stand-alone games such as Solitaire or Tetris.
What I'm saying is that if you have an obsession to get this nearly 6 year old computer to run W10, you'll have to take some risks (such as flashing the BIOS) or spending some money and paying someone to do it for you.
And there is still a pretty good chance it will never take W10, and there are no guarantees anywhere for you.
However, if you wish to use this computer to experiment with W10 upgrades as many of us do here, great! Give it a go.
We just don't want you to waste time on something that maybe only has a 20% chance or less of working even if you know what you are doing. It's your computer; so just trying to give you some more insight on the overall process. I've been playing around with upgrading old PCs to W10 for 2 years now; and I've attempted to put W10 on computers as old as 2002. Just for the heak of it. With this understanding you may still wish to proceed.
Best of luck,
