Brand new custom build keeps restarting!?

hey guys,


Processor (CPU) AMD FX-4350 Quad Core CPU (4.3/4.2GHZ - 4MB CACHE/AM3+)

Motherboard ASUS® M5A78L-M/USB3 (M-ATX, DDR3, USB 3.0, 3Gb/s)


Graphics Card 2GB NVIDIA GEFORCE GTX 650Ti BOOST- 2 x DVI, HDMI, - 3D Vision Ready

Memory - 1st Hard Disk 1TB 3.5" SATA-III 6GB/s HDD 7200RPM 32MB CACHE

USB Options MIN. 2 x USB 3.0 & 4 x USB 2.0 PORTS @ BACK PANEL + MIN. 2 FRONT

Power Cable 1 x 2 Metre UK Power Cable (Kettle Lead)

I have had this PC for almost 6 months and haven't been able to use it for a day. The compony I bought it from said they had stress tested it for 4 days with it being fine and that there is nothing wrong with it, but when I plug it in at home it will cut out randomly (maximum time on was 4 hours before a crash) I checked the crash logs and there was a fault logged whenever it crashed at my flat.

I have had an electrician come around to check the voltage of the flat and he said it is fine, but the pc still keep resetting itself randomly, sometimes it wont even boot past the beep and just fail till I leave it for a while.

Can anyone help me?

  1. What exactly is the make/model of that 450W quiet 80 plus PSU? Sometimes an under powered or cheap PSU can cause that when the PC is stressed like gaming.
  2. Thanks for the reply, Antec basiq - vp-450. The compony said they ran it for 4 days on a stress test with no problem, is this something that happens quite a bit to people? because I feel like a crazy person :( I will take it to the shop tomorrow to get see if they find anything wrong with the PSU if not I don't know what to do.
  3. The Antec basiq should be an OK PSU for that setup. It sounds like this is a pre-built PC.
    What exactly happens when it 'quits' on you... Crash, BSOD, shuts down, screen goes off but PC keeps running?
  4. Complete shut down then restart, but some times it struggles to boot up and wont even make it to bios.
  5. Man, that does sound like a PSU issue. I suppose even quality PSUs can be bad, tho.

    I just checked on that PSU. If this is it: only has 2 18A +12V rails. Smaller than I thought Antec would use with a 450W rated PSU. Checking a little further, I found that that model is listed in a lower tier than the rest of the Antecs:

    That may not have the power to run that CPU and gfx card at full startup power. Try this. Remove the card and its driver. Then reboot using the integrated video. Run it like that for awhile and see if the issue returns. If not, I'd have to assume the PSU is not big enough for the components you have... or has an electrical problem.
