was wandering if upgrading the power supply would do any good.
Absolutely not. The power supply has nothing to do with performance and is either adequate and working or overloaded and failing. Black and white.
Requirments for it was a minimum of 250w supply.
This 250w figure they quote as a minimum requirement is only meant to ease the minds of every ignorant buyer, just about every PSU produced nowadays is at least 250w. They are basically saying "yeah, go for it, it's compatible with everything!"
Unfortunatly it has no APG slots only PCI.
And, as you were probably told before you bought it, PCI graphics cards are a waste of money, but I guess you just had to find out for yourself.
I thought about ram since it can handle up to a gig but going cheap is the main thing at this point.
If you buy RAM, it will need to be of an outdated type, and you will waste more money. It won't help. In fact, if by some chance your PC has decent RAM fitted, the addition of a cheap and nasty RAM module will probably slow it down even further!
