I was gonna do a 2004 pc build but I decided I was gonna switch it to a 2007 retro build and I wanna keep the totally rad cooler master all copper heatsink(couldnt find a name for it online)

I know some time around 2006 was when they stopped allowing for full 32 bit hardware support but do yall know the specific last cpu to support it?

Yah it's a 850 watt psu

So this all started when my gtx 1060 6gb broke just outside its warranty period and I didnt have a apu or enough money to get a proper replacement so I bought a gt 1030 as a stop gap solution skip to 1 year later I want to upgrade and have some money so I buy a rtx 2060 and to my surprise it doesnt work once I get to windows it works for like 2 mins then the monitor says no signal I tried every trouble shooting trick in the book but nothing worked so I retured it and since there was a sale on a 1tb Samsung ssd I spent some of my refunded money on that and a gtx 1160 welp I did a clean install of windows on this new ssd and I used the gtx 1160 while I was setting it up it only keep a signal for like 1 minute after I actually booted to windows so wtf is going on? Heres the things I have tried so far rebuild the whole PC, take out the cmos battery, reinsert the card, unplug and plug the power supply back in. So what can I do to fix this? I'm just really frustrated and confused at this point.

So my acer gn246hl says no signal even though I'm using the same dvi cable and pc the only thing that's diffrent is the case so naturally I tried to change the input of my moniter but I couldn't get into the os all it would do is start up say there's no signal then turn off I rebooted my pc and moniter multiple times to no avail I even unplugged the gpu and put it back in to no success please what do I do I don't know how to fix this I know this is a great cummunity so I'm sure someone knows what I should do
