My wife has a desktop Dell Intel pentium 4 email@example.comGHz,128MB DDR SDRAM @333MHz and I added 256MB to this, and it has a 40GB HD ATA/100 Value hard drive. It runs very slow, I have run the tango on it many times. I have to wait for EBay pages to load, sometime more than a minute. I get a lot of "(Not Responding)" messages in my Titlebar. I can hear the computer chugging and chugging along and blinking fast then slow then not at all when I get these messages. I run Photoshop and have a printer hooked up. In a quick diagnosis, can you tell me if it is worth trying to upgrade this ? Is it just slow because it is early technology? Should I expect it to run faster or are you not suprised? Is an upgrade possible and if so is it expensive and worth it? I do not know if it is even possible to upgrade it and if I did what would be the max it could go?
