barring the flaming that's sure to ensue from upgrading this machine....... my girls computer had some problems, i got it fixed, and was going to build her a new machine, however, where she goes to college they are laptops only. so instead of building a new machine, im putting some of that money into component upgrades. sadly its a FAIL inspiron 1501, but after; new 7200 rpm hdd with better cache 2gb 4-4-4-12 corsair new fan it was running much better, the only thing i am yet to figure out, is what the limitations are on the processor, because it sucks.... its a sempron 3500+ i found the socket type, but an yet to figure out what is the fastest processor i can stick in this puppy is. if anyone is savvy, it is a "Socket M2/S1G1" it is an AMD socket, but are there any processors that i can replace this 3500+ one with? any help would be awesome, thanks.
