Hey All! Just need some input before I go swapping and replacing parts, not sure if this is the right section but I figured you guys would understand PSU loads and hardware set up more than any others... :(
I’ve started to notice some worrying problems with my PC that I built a few months back and I can't seem to find where the fault is coming from.
The first issue I noticed was that my computer would randomly bsod. The only way to recover would be to hard reboot (just hitting reset will cause it to fail post). Once back to desktop I would get a Windows error referring to an issue with nVidia drivers/hardware.
Another problem is when I'm gaming (Fallout 3 is the main culprit lately) the screen will switch to a random colour (last was a shitty brown) and then just hang there again until hard reboot.
Finally and more concerning I've recently noticed after moving my PC up onto my desk off the floor a very high pitched squeal, it's very fine and quite quiet but just the right pitch to annoy the shit out of you, especially when your PC is an arms length from your ear.
Also during my last play of Fallout I noticed a deeper buzzing when in game, that would go away when I hit ESC for the menu, but then come back when I go back in-game. The rate and pitch of this buzzing also changes when I do stuff in game to put load on the graphics.
I've done a little research and it seems to point to an weak/poor quality power supply. But it could well be my Graphics card too... Please Help.
CPU: AMD Phenom II 955 BE
MOBO: MSI 790FX GD-70
RAM: 4GB Corsair XMS3 1333mhz
GFX: XFX GTX 260 (216 core)
SFX: Creative X-Fi Extreme Gamer
PSU: Coolermaster RealPower M620 (620W)
HDD: 1x 1TB WD Caviar Black + 1x 500GB Samsung Spinpoint F1
DVD RW Drive
Case: Antec Twelve Hundred (running 8 fans in total)
CPU Cooling: Zalman CNPS9900
Obviously 620W would seem like enough but I do have allot of hardware running, so could that put allot of strain on my PSU? I'm just thinking it may be struggling when under load.
I'm running Fallout 3 on Max settings at 1440 x 900 Res.
Oh and nothings OC'd
