Most games crash while playing.Could this be a PSU problem?

I recently upgraded my PC by buying a new CPU AMD 5200+ 2.70Ghz overclocked to 3.0Ghz and all games started crashing.Here's my PC's specs:

Motherboard: Gigabyte-GA69VM-S2
CPU: AMD 5200+ 2.70Ghz currently 3.00Ghz
Video Card: Galaxy GTS250 512MB GDDR3
RAM: 3x1GB Super Talent
HDD: Seagate 500GB
PSU: Fortron 400W
2xDVD-RWs
OS: Windows 7 x86

For example when I start GTA IV the PSU starts making a loud noise and after 15 min the game freezes.Not only GTA IV but Crysis,Metro 2033,Need for Speed Shift...

All temperatures are normal except the motherboard. It was stable until I bought the new CPU. The old one was AMD 4000+ 2.1Ghz
CPU:30 to 40 degrees on standby when playing maximum 60
Video Card:45 degrees on standby and up to 65 while playing
Motherboard: 45 degrees on standby and up to 67 when playing
All help would be appreciated :)

  1. GTS250 on Fortron? What is that brand. Could very well be the PSU. Its not capable enough to provide the Amps and voltages when you overclocked. Change it. Get a Corsair VX450W

    That loud noise is the PSU fan starting to work at max speed probably. Always a bad sign.
    What model of FSP PSU is that? If it's an older model it might be light on the +12V power rail.
    And if's a few years old - PSUs can 'age' over time and loose the ability output it's full rated power.

    Was there any crashing before you OC'd your CPU? Might be best to go back to stock and do some testing there - just to make sure it IS a PSU only problem.
  3. Its not the worst power supply the GTS250 isn't all that power hungry of a card. Did you test the stability of your system after you overclocked with Prime95?
  4. There wasn't any crashing until I changed my CPU and yes i have tested it before.Here's the link http://img827.imageshack.us/i/stability.png/ http://img827.imageshack.us/img827/3324/stability.png
  5. I'm using the stock CPU cooler
  6. Did your CPU crash at stock speed?
  7. No not at all.It has never crashed.
  8. Ah man I just got a blue screen for the second time.I only saw it saying ''Dumping Phsyical Memory''and the PC restarted.What can it be ?
  9. sry for the bad link. Check now :)
  10. sounds like your overclocking is the problem. change it back to stock clocks. have you overclocked before? maybe you need to bump up the core voltage.
  11. Im thinking along the lines of possible bad ram, Plus that power supply seems a bit on the low side, I would go for a nice 500w+ Brand PSU just for safety.
  12. I set my CPU's settings to default and the games don't freeze anymore but now my motherboard overheats up to 75 degrees :(
  13. Does your case have adequate ventilation? At least a decent exhaust fan is needed. What case do you have? Id say a 400w PSU is a little low for that setup . What amperage does it say on the 12v rail?
  14. On standby it's 12.03 but when playing 11.96 and the case is nothing special though.Tomorrow I'll install another fan to see if anything will change
  15. All problems solved cuz I bought myself a Fortron Saga II 500w PSU
