PC able to turn on but cannot post

post #1 of 35
Thread Starter 
hi folks

ive a i7 960.

sometimes i am able to turn on the pc but unable to post. but when i able to post, i have a cmos checksum error.

other times, the pc would just turn off, turn on, turn off, turn on repeatedly.

im getting kinda frustrated as this is my first intel build after so long.

any advice much appreciated

tanx !!

Make sure that your RAM is in the correct slots (I had the same problem, and switching the slots fixed it)

Try reseating the ram and breaking down to minimum needed hardware i.e. cpu, ram, no dedicated video. If that does not work try with just one stick of ram.

+1 to this. I just got a computer from a guy for fifty bucks with the same symptoms as yours except not even a bios screen. I took out all but one stick of RAM and works like a charm now. Time to RMA the RAM

In your case you should run memtest with 1 stick at a time and find the bad stick/s and then just RAM the bad. Also look at the boards and make sure the color is exactly the same if one is a little lighter it is from a different batch and that can cause issues.

it is better to RMA the whole kit if they came as a kit in which case these came a a kit.

Fair enough I deal with the manufacturers directly so...... for me it's by the stick.
