Sorry if I break some rules by posting this just like that, but I'm DESPERATE, literally.
A few weeks ago my mom took my computer to some fixing place, cause it was freezing for no reason and was VERY slow. So there they Re-installed WINDOWS and kept all my data. The first days after that happened it worked just fine, but then I moved and something weird start happening, FIRST, the internet disconnect every few minutes, at first I thought it was an internet problem, cause I just moved. But no, the internet company came and they "solved" the problem. IT DIDN'T WORKED whatever they did. My windows live messenger kept disconnecting and saying "the conection has been lost... blah blah" or something like that. AFTER THAT, the computer started FREEZING everytime I turned it on, you see... I could use it just fine for hours then turn it off till the next day and it wouldnt turn on. after the inital start up before the WINDOWS XP is loading and whatever appeared... the screen turned BLACK with a " _ " blinking on the screen, and it would respond to any key. so I turn it off and on again, over and over again the same problem. sometimes it appeared a screen with several options to start, and then after the 30 seconds on when I click one it just FREEZES! and i try like 100 times to turn it on untill it finally works, and then FREEZES AGAIN! its very annoying!! and I don't know what to do! please can someone HELP ME!?
pd. I dont have the windows install cd, if you recommend I re-install, is there another way to do so, without the cd? PLEASE HELP!
