The OP said they had a 7 year old PC. Best case scenario that's first gen Core i7. That's long in the tooth and they most likely weren't gifted a PC that high end. 32 bit Windows means they have at most 4GB RAM (minus any video RAM for total available), more likely 2GB.
Here are a couple starting points if you want to spec out and build a system.
Both of these are Core i5, 16GB, 250GB SSD, 2TB HDD and include a new Win10 license.
If you go this route, you should take a bit more time to select case, motherboard and cooler for features. If you want to trim a bit, you can drop to 2x4GB RAM and/or drop the 2TB secondary drive. GPU prices are a bit rough now due to mining demand. I consider these to be good general purpose specs for a 1080p gaming. It would be preferable to get a 6GB 1060, but would require boosting the budget. You could also go to a faster Core i5 SKU for $30-50 more.
