hi guys, i'm edz...45 yrs old... that old ha? anyway, i need your help. i got this p4 computer with an asus page mx board & sis video card. trouble started when square patches started to appear on my monitor. tried to re-seat the video card & worked fine for a few minutes then suddenly went blank screen. then i removed the video card & used the built in video instead. it booted but won't load windows coz it's saying something like a corrupted dll or something. then i reseated the ide cables & power cables and rebooted again but nothing showed on my screen anymore. then i noticed that the power seems to go intermittent (like on, off, on, off continuously and won't stop (even the processor fan acts same way). i checked the power button & it was never stuck. i thought it was the power supply but when i removed the 4pin atx 12 volts on the mother, the computer went on & power seems okay (but of course it didn't boot). when i reconnected the 4pin plug again on the board then power on the computer, it still is powering up intermittently non stop. pls help. i'm not a techinician but i understand a little about hardwares. thank you so much & hoping to hear from you soon.
