Narrowing down the fault?

Knave · 29 Sep 2007 at 19:14

Recently had a small upgrade to the Core 2 Quad CPU with basic motherboard and memory.
Has been great up until now.

Sometimes from a cold boot or reboot/bios checking the PC will not boot up (back screen, fans going, etc), need to turn off and try again a few times to make it get a post.

Now having only a few graphic problems as well (can happen when just in windows, gaming or watching a video)
The sceen will go blank with vertical coloured lines and the GPU fan goes to full speed mode until powered down.

All main drivers and MB bios have been updated to the latest.

Was thinking that the PSU might be a bit low for the new CPU when all other hardware is connected to it.
Tried some tests to see what could be at fault but no luck yet.

Hope someone can possible help me out at all.
Thanx

if u think your psu is to low then why not get a higher wattage one eg corsair just to put ** mind @ rest

Reseated CPU but still the same problem, even tried latest Bios as well.

Another problem now looks to have surfaced, using PC normally when I could smell burning/electrical coming from the case.

Turned PC off and took all the parts out to check.
All I could see is a capacitor below the Northbridge has some sort of sticky substance that have been flicked/splatted down the board for about 4inches away from it (as board stands up)

And from above the capacitor a part of the video card PCB is usually in the way also has the same substance one it

The capacitor hasn't popped via the top as the do but its the only place it could have come from.
Will issue an RMA as only less than a month old and has 2 faults.

Capacitors don't always pop, sometimes they just leak a thin oily substance
