Computer crashing after motherboard change

Blacksheep1979

If usb devices affect the performance/stability of your computer then I would definately think about changing the psu - what other components do you have?

AMO, have a look here http://extreme.outervision.com/psucalculator.jsp if you input all your hardware/devices, it should give you a rough idea of what wattage psu you need. Hope this helps.

EDIT: it may also help if you flash your board to the latest bios.

Whatever, the reason of this fault, you should NEVER use a less than specified Power supply. While it may appear that the computer will run fine, it will not.! From time to time, the PC will freeze or crash. Look up the term 'Brownout' and you will receive your answer. Brownouts are caused when not using the correct rated PSU. You will be causing harm to your CPU Now, if you are not using the correct rated Power Supply. After all a new PSU is less than £15 online from aria technology or spotoncomputers.

Thanx Blacksheep1979. The USB device quickens the crashing of the computer, but it will crash anyway.

I have just ordered a 600W PSU from Ebuyer:

Hopefully this will resolve the problem.

I currently have:
- 4 x 512Mb RAM (I reduced to 1 stick in case of memory errors)
- 1 x LeadTek 6600GT PCI-E Graphics Card
- 1 x DVD ROM drive
- 1 x DVD-+RW drive (removed to reduce load)
- 2 x SATA drives (1 removed to reduce load)
- 1 x floppy drive

Thanx

I agree entirely. The ASUS board I had before was fine for the iCute case with 350W CPU I had. When I got a replacement board, I did not think to check the CPU requirements. When I started to get the random crashing, I decided to read the manual and realised it was 400W recommended.

Hopefully my new 600W PSU will resolve the issue (hope it fits!).

I certainly wouldn't have thought that my new DFI motherboard would use that much more power than the ASUS, but I have done some reading up on it and apparantly ASUS boards control the flow of power to the motherboard to ensure more system stability. I assume this means that because power usage peaks and troughs, the ASUS motherboard builds up a buffer or something which the DFI does not.

Either way, we'll see whether this new PSU makes a difference.

Thanx.
