My computer has been running fine for 2 years but now when it turn it on, it turns off again and again. What could be the problem? It turns on with all the fans running for 10 secs then turns off for a few seconds and repeat.
Things i've added recently was a soundblaster 2zs and I read my 2x1gb ram sticks had to go on the same colour. i had my 2x1 running on different colour slots.
and my sticks are 2.2 and I believe my mobo stock is 1.8 so I bumped it up .4.
could any of those had caused this and if so what could be the damages?
COuld simply be your PSU has aged and is now marginal...
YOu can set your mem clocks to stock, and see if stability returns. check with mem manufacturer to see what voltage is requiired at whatever mem clocks/latencies your are running.
Reference your mb manual to find out which dual channel slots need populated in what order; you might not be able to hit as high a mem clock with dual channel access, but, the system would still likely be faster overall.
Double check that the CPU heatsink fan is actually spinning. On a stock cooler, you won't hear it over the sound of the PSU, case, or GPU fans. I echo that possibility of a failing PSU, but just double check the heatsink fan. If this fan doesn't spin, or does a half spin, this would explain the absence of display and why your comp turns itself off.
Thanks for all your help guys. I did what T_T said and switched them back from they way they were but that still didn't help. I then tried to power on with just one stick of ram and it worked! So I guess my other stick is dead? Maybe I didn't install them correctly? Glad it wasn't anything serious. Thanks again.
