Hello all,
I think my desktop is PMS'ing:
It (the PC) cannot see my Logitech G11 keyboard nor my Razer diamondback 3G mouse (which actually lights up upon booting, but doesnt seem to work). All keyboards should flash all "lock" lights once upon booting (caps lock, scroll lock & num lock) but the G11 doesn't, so I don't know whats wrong with it, or with the desktop (it used to flash but then it stopped all of a sudden).
Southbridge problem maybe?
Since the desktop cannot "see" the USB G11 and diamondback, I bought a PS2 keyboard and mouse and plugged them in with the G11 and diamondback connected via USB and did the following:
SOMEtimes, when I turn the PC on, it attempts to boot but fails and starts beeping constantly for 3 - 5 seconds then turns off.
On other trials, it DOES boot successfully and I'm able to log into windows 7 and move the mouse for a few seconds, after which it freezes altogether, no keyboard or mouse functionality.
All of this started happening after there was a storm, so I THINK lightning hit the house and did something to the desktop. I don't know if the PSU protects the computer's hardware from such things.
The storm happened while the computer was off.
What might be wrong with the desktop?
How can I troubleshoot by testing each hardware component individually and not just buying a new motherboard and not solving the problem?
Awaiting your replies,
Thank you!
