Sony Vaio desktop that is about 4 years old.
Starts great most of the time I get 1 beep also.
Then once in a while I go to start it,I get no beeps,computer sounds like it is starting,fans spinning not sure if hard drive is spinning and I get black screen.
Also sometimes I have experienced desktop is broken up like little squares on screen view broken up,is that a bad video card and causing the failing bootup?
If it is video card causing no boot can I install a new one on motherboard to fix failing boot.
Bad power supply?
Bad motherboard?
Bad hard drive?
Bad CPU?
Should I try clearing CMOS?
Should I try a new power supply.
Is there anyway to test power supply while boot is failing?
Please help....
