Ok, here's the situation. I've done almost all i can think of other then replacing the motherboard. I have a Gateway 600 YGR laptop.... win XP pro, 512MB ram, 60GB 7200 spin HD..... and i've been getting blue screens of death in the past, and finally, it didnt reboot like it usually does, instead it gets past the bios screen and sits with a blinking cursor in the top left corner of the screen. Now i've tried just reloading my OS, but i cant boot to ANYTHING, not a floppy, or cd, or HD. I found a forum that discussed how these mobo's have a design problem, so i ripped it all apart and fixed that issue (the 4 posts that hold the cpu heat sink on were poorly designed), still nothin but the cursor! i've swapped out memory, swapped out HD's, done about everything i can think of!!! If there's ANYONE that might have any clue what is causing my problem, i'd GREATLY appreciate some advice. Thanks again for your time!
