Monitor oes black & pc becomes unrespondingLocked
I have a Intel core 2 duo pc. Mobo – DG41WV, (1+2) GB RAM, 500 Gb HDD.
I have dual booting (XP + 7 32bit).
XP works fine but in windows 7 a problem occurs randomly.
My monitor goes blank, HDD, CPU, MOBO are running. Keyboard light becomes still. It does not respond. Power switch remain on. Then I need to power off it & then power on.
This happens randomly. Sometimes 3-4 days does not occur.
Sometimes it happens while booting.
Sometimes it happens while working in 7.
But in xp it never happend.
I tried by removing ram.
I tried with different monitor.
I tried by installing windows 7 ultimate 32bit several times.
I tried with kaspersky, avast, bitdefender, quick heal.
But the remains same.
I dont like to play games, so no games is installed in my pc.
Can anybody help me please.
