Okay so i bought thiscomputer about a month ago. i7 920 proccesor 430w PSU seagate 500g HDD 3g ddr3 ram ati radeon 3400 series when I first had it it was fine for about 2 days before it just reset overnight by itself and wouldnt boot up again. I have reformatted xp pro about 6 times now, everytime I do it works for about 2 days before the computer restarts and get stuck at the xploading screen. If i let it load long enough there is a ticking sound coming from inside the desktop. No other boot up modes work (safe mode, last config, etc.). I was thinking it could either be the HDD or maybe my copy of xp.
