first of all my system config:
HCL PC with DG31PR, C2D 2.93, RAM DDR2 800, WD 320 GB HDD.

it gives some times display like when I change RAM it shows display and boot normally but when it restarts, same problem is there.
smilarly, when I remove CMOS it gives display but again after restart, same problem, no boot, no display.
after no matter how many times you restart but no luck.
then again you do the RAM reinsert or CMOS clear... then it gives diplay and boots normally.. but only for one time after shutdown aur restart it has a ame problem.

my pc power up, CPU fan running, but no display and POST.
what I have tried-
- CMOS battery is weak so I changed it.
- I have another 1GB DDR 2 RAM
- check with another original HCL PSU
- Check CPU and heat sink.

but still no luck..

please help me guys..
