Are you buying very cheap units because if you're not your electricity supply should be checked.:surprised:
I've had the same PSU for the past 8 years for reference. Back in the day I had 1 cheap one die and another go bang.

Does your monitor work or does it stay blank in that early phase.
Cheap PSU is a bad false economy, but the fat right now is it won't boot.
So. logic must be used.
As Ferral said unplug ALL non reqired USB, just leaving Keyboard and mouse.
With basic cpu, cooler, ram, psu and graphics plugged in, if it won't even POST a BIOS screen then its a case fo changing one thing at a time, preferably by borrowing cheap bits to determine the dead item.
Might be anything from Motherboard to CPU to PSU etc, SO.....
get borrowing from friends.
Graphics card and PSU ONE AT A TIME,
Do NOT change more than one item.
I may suggest unplugging your front panel connectors leaving just the power switch connector and try that.
I just had similar issues with system not booting and found it was my reset connector stopping the boot.
Still not fixed. I tried with other PSU..so it'not that(A corsair VS550). I removed everything from the motherboard and put it back on . Someone told me to remove the CPU cooler and heatsink and. touch it to see if it heats up..it does.Kept it on for max 2 sec. if this a definitive ok? no idea. Then I put1 memory stick back and no more breep.Then I put the GPU back and no more long beep.Monitor is on and green but shows nothing.Removed everything from the font panel still nothing. At this point I consider myself defeted...I'll go with it to a shop tomorrow. Forgot to add the full specs before: Phenom II x4 2,6Ghz.An Nvidia gts 250 . 4gb of kingmax(2 sticks) -1333 Mhz DDR3 and a Gigabyte ( GA-MA770T-UD3P) motherboard.It's quite and old build , maybe it's time has come
Seems like I need a new GPU. Tnx for the help guys.Case closed
