After PSU failure: boot sometimes...
My PSU died and I replaced it with a corsair HX 620w.
The strange thing is that now when I try to boot I get some power, i.e. lights and fans and similar starts but the computer doesnt start booting, i.e. I dont even get the short beep indicating that the boot process is starting. But the funny thing is that once in a while, say after 5 tries It works fine. It boots as it should and there is no sign of problems at all. If the computer starts as it should, I can restart it from menu and it restarts without problem, but if I power off and let it be for a while then it will not start.
Further when it wouldnt start, I can do one of two things: 1) turn of power using switch on PSU or 2) reboot using the reboot button on the front. Pushing power button on front will not work.
What I have:
MSI P35 NEO-FI S-775 DDR2 SATA2 GBLAN FW ATX
INTEL CORE 2 DUO E6850 3.0GHZ 4MB 1333MHZ S-775
MSI GEFORCE 8600GTS 512MB DDR3 HDMI HDCP PCI-E
CORSAIR 4GB DIMM DDR2 800MHZ PC6400 CL5 (2X2GB)
So, is there any way to know if it is the mainboard, the new PSU or the GPU? Or what... Any suggestion?
