First of all I SWEAR by my $50.00 Compaq 6910.p T7500 Notebook. It's bullet proof, it has THE BEST keyboard ever made (I type 140 WPM which is a curse) and as an Intel Core Duo, it's not that bad of a Pre Pottery Neolithic B (PPNB) Notebook of circa 2007 vintage: I need more material before I can attempt an answer Q. What's yer O/S? WIN10 is too much for your machine. Go now higher than WIN7 Pro!!! Q. What's under the hood? If you've got a T7100-T7300 CPU most post 2014 software will crash on it---it did my old T7300. If you have a T7500 (2.2Ghz) you are also kicking an ATI Radeon 2300 seperate than that wretched Intel G55 integrated VRAM . The ATI isn't supported by WIN 10 and stumbles on WIN 8 Q. Tell me yet MAXED OUT on 4GB DDR2 SDRAM. Some machines only came with 1GB (x2banks) which struggles just to turn the machine on Q. Your not doing a Rookie mistake like having a whole desktop loaded up with open apps &a Icons ? Q. Did you adjust your auto executables? Or what we called in my day...
