hey,
i have the following problem:
for a couple of days now, when booting my PC, in 9 out of 10 the all fans will start running, but my monitor will show 'No Signal'. there were no POST beeps at that point.
i will then have to try a couple more times or wait a while, after that it will eventually boot normally and run w/o problems for hours. which i find curious. on the next boot the problem likely returns.
what i tried already was removing 1 or both of my 2 RAM sticks. when i used only one of the two, i get 4 short beeps and the PC will shut down after. with the other one, it will eventually boot, but not after giving me the 'no signal' for at least 5 tries. i am pretty sure that with both RAM sticks connected, i now also get the 4 beeps, this was not the case in the beginning.
i googled the POST beep code and came up with this: "
4 short System timer failure- The system clock/timer IC has failed or there is a memory error in the first bank of memory"
this is my mb:
ASRock > H77 Pro4-M
this is my RAM:
XMS3 — 8GB (2x4GB) DDR3 16 MHz C9 Memory Kit (CMX8GX3M2A16 C9)
one other thing i noticed is a little red light on the front side of my PC, i think it comes from my harddrive, will not light up red when booting and getting the 'no signal', but it will light up when the booting works.
also i might add that i am not 100% sure that one of the RAM sticks is broken or something, since even when using only the 2nd i get troubles booting and only 1 out of 10 tries works.
would appreciate any kind of help. how can i narrow this problem down? are maybe both of my ram sticks faulty? 1 not working at all anymore, the other causing the 1 out of 10 boot problem? or is it my MB? could this red light of my -assumed- harddrive, that is not lighting up when the failed boot attempts happen have anything to do with this?
thanks a lot!
