PC won't boot with USB plugged in + strange crash issues

Hey Everyone, Ive got a strange set of circumstances to both my PC booting with no USBs and crashing randomly.

First off, The PC will always boot if I switch the power supply off and unplug USBs then turn powersuppy back on. Ill start with the problems.

Afew days ago, my PC just powered off, as if someone had simply switched it off at the switch. trying to turn it back on the PC powers for a second then switches back off. Ive been able to turn it back on by letting the PC sit off for an hour or so then trying again, OR turning off the PC unplugging the USBs and turning it back on.

BUT, regardless of successfully turning the PC back on, it will just randomly power off at any given time. There doesn't appear to be a trigger for this.

--What USBs are plugged in--

2 external harddrives
1 audio interface with microphone + headphones
Razer keyboard
Razer mouse

BIOS are set to boot correctly

I've:
-Check all temperatures and fans and heat is normal
-I've had success with only having my mouse and keyboard plugged in, crashes seem to be further apart

My other experience with the same crash is when I plugged in my laptop to the same powerboard to find my PC instantly turn off, I tried getting it on a seperate powerboard for it to just crash 5 minutes later. This has made me concerned that the powersupply is faulty and cannot support my PC booting + USBs which would mean the motherboard is fine I suppose xD

--History of the PC--

-About 2 years old now
-Originally was placed into case without back pins so the motherboard originally was shorting itself out (which is almost what it feels like its doing again)
-Sometimes when the PC is left off for to long, The computer cannot detect screens, only way to fix is to just turn on and off over and over.

At this point Ive ordered a new motherboard as I know the motherboard is going to die regardless due to its origianl issues. I have not ordered a powersupply as I'm not 100% sure if this could be a potential problem.

If anyone has some similar experience please let me know as I really cannot afford to start just replacing parts and use the process of elimination to figure out whats happening here.

    Sorry ive updated my post to include which usbs are connected. as for the boot, it works fine when the PC starts, booting from an internal harddrive, I havent had to change BIOs at all to get it to boot, seems to be purely hardware
  3. what power supply do you have?
    The part where it'll die and won't turn right back on leads me to believe something is overheating. when you plugged in your laptop (I assume powerboard is a powerstrip/surge protector) to the powerboard caused the pc to power down, also makes me think power supply

    Ive currently got a Thermaltake 750W Toughpower Gold power supply.

    As for overheating he highest temperature after a crash has been my GPU at 53c
  5. does the crash manifest when you arer in safe mode/bootable environment?

    Havent tried either of those. I can boot into safemode now but since I cannot replicate the crash it could take a day or two for it to crash
