My 4 year warrenty ran out and i dunno i guess to get it running again would be nice because it has a lot of sentimental value to me... Well i tried reformatting the computer, and when im installing windows it sends back these errors that says that it cant write msyuv.dll or nic1394... etc, and then when i press escape to skip the file, it seems to continue to go through and then it might do the file unable to write a few more times and once its done it goes to the main windows setup screen and it has the welcoming and everything and all the sudden i get this air that says memory_management... I dont exactly think the ram is the problem because i have 4 sticks of ram in there that equal out to 512 and so if one goes bad i doubt the others would too... I had this problem for about a year and never tried to fix it, and like gateway sent me a new power supply and motherboard + CPU and still no luck... So my belief is the windows cd just sucks.. And it wont boot my windows pro cd so basically im SOL for right now with that computer... So if you please could help me fix it, it would mean alot..
