i'll go straight to the point. a few days ago i opened up my pc for cleaning and some cable management, and after all that was done i thought why not install the new HSF (OCZ Vendetta 2) i have? actually i had bought it some time ago and didn't use it because i didn't want to use the thermal paste that came with it, i wanted to start off directly with something like Arctic Silver 5 but didn't get around buying that so i never used it.
but that day i figured why not and just went ahead and used the OCZ thermal paste that came with the HSF. but then the issue was that i couldn't properly install it because it was pretty big and i couldn't really access the thumbscrews, also my motherboard has a large cooler itself (MSI X48C Platinum). and since i was in a hurry and also wanted to format my pc soon, i gave up and just installed the Intel HSF planning on installing the OCZ later. but since i had already cleaned the Intel HSF i had to use the remaining OCZ thermal paste for it. well, i applied it and successfully installed the heatsink, after which i booted up and went to the BIOS to see if it was ok, and then i saw the processor's temperature was around 85C-90C degrees (my processor is a Intel Core 2 Quad Q6600 G0). at that time, thinking that it was the problem of the thermal paste and afraid that i might fry the processor, i shut the pc down and left it till the next day.
the next day i got myself a tube of Arctic Silver 5 and after cleaning all the parts, i decided to try instaling the OCZ Vendetta 2 again. i want to point out here that i was using alcohol swabs and a soft cotton cloth to clean the stuff properly. this time i successfully installed the HSF (although it was a major pain), but then when i booted the PC the following was the behaviour:
i start it up, all the lights turn on and fans start like it normally does but then the pc shuts down itself after about 3 seconds. then it starts up again itself and runs like it's normal, but then after about 10-15 seconds it shuts down again, then after a few seconds starts up again and then shuts down after about 10-15 seconds. it just keeps on repeating this. another point is that during this entire time my monitor had no display. the power LED was always orange instead of green and the display showed nothing except the message "Power Saving Mode", as if the monitor wasn't connected to anything. all the LEDs and fans etc of the pc work properly though.
now when this started happening, i shut it down by pressing and holding the power button, then cleaned and applied the Intel HSF again (with the Arctic Silver). but i was still getting the same problem.
from my own experience i know that this problem occurs when the HSF is not installed correctly and the processor is overheating but i am pretty sure that i am installing both HSFs properly. i even checked all cables and connections and everything seems ok.
here are the complete parts:
Processor: Intel Core 2 Quad Q6600 G0
Mainboard: MSI X48C Platinum
RAM: Corsair XMS2-DHX 2GB+2GB DDR2-800
VGA: Sapphire ATI Radeon HD4870
PSU: FSP Epsilon 1010W
all are on stock, nothing has ever been overclocked.
so what's wrong with my pc?
thanks in advance
EDIT: another thing to note is that i do not get any beeps at all.
