hello, my pc won't turn on. before this, it already has some problems. I tried to plug my iPad and iPhone to sync it, but it gave me errors, so I rebooted it. when I rebooted it, it gave me 1 long beep and 6 short beeps. so I tried checking my wiring and clearing the CMOS. after doing that, I tried rebooting it again, but the screen was blank. the fans and drives were running perfectly fine. so how do I fix it.
spec sheet:
Intel pentium e5200
msi g31m3 v2
windows Xp professional
4gb ram, but due to xp, so only 3gb used.
maxtor 500gb and seagate 1tb hard drive
atop 500watt psu
cpu over clocked to 2.75 ghz, stock cooler.
help please.
