System crash (overheating).

[Basilikos]

Perhaps I missed it, but what's your North bridge cooling like? Also, what thermal grease has been applied to the major heat sources in your case? Is it high quality? Has it been determined what heat source is causing the trouble?

;( ;( ;(

Went to Zul Aman yesterday - second boss, fast fight, lots of animations,
monitors (both) turned off (standby mode), Teamspeak was still working
(for about 3-5 seconds) then my whole PC rebooted. :cursing: :cursing: :cursing:

Any ideas?

RAM?
Power?
GFX Card?



PS:
I'll do a complete RAM check this evening after I've installed Windows 7.

I had issues like that happen to my older Athlon 64 / 6800GT system when my 500W CoolMax power supply was not doing its job. The 8800GTX should be fine around 80*C - that's hot as hell, but I've been running my stock-clocked eVGA at that temp at full load for two years. What power supply are you running? Brand is usually more important than pure wattage - I'd take a 620w Corsair/SeaSonic over an 800w Thermaltake any day. To cool the 8800GTX, a Thermalright HR-03 Plus with 120mm fan is an excellent solution.. be sure to install the ram heatsinks properly too.

thanks for all the replys. I really appreciate it.

my power supply:
Thermaltake Toughpower 600W
600 Watt, ATX 2.03, ATX12V 2.0,

(Harddisk-Raid is gone)


I've checked my RAM yesterday with a Microsoft Tool.
Problem with that tool is that it can only handle and check 4 GB of RAM of my 8 GB.
If anyone knows a tool that can handle & check the full 8 GB please let me know.
Check was completed without any errors.

Temperature in my room ain't that high. We got winter here, very rainy and very cold
so the sytem shouldn't have any problems I think.

Cooling of the case:
CPU + GPU are cooled by the fans which the manufacturer installed on it (CPU was bought in a box)

the case got
- a big fan on the top
- a fan for the harddisks
- a fan on the bottom
- a fan on the left side of the case

my main question is:
my TFTs went black (standby lamp turned on) but the teamspeak was working for ~3-5 seconds
before the PC restarted. So what could caused that? Usually I'd say it's the GFX Card but can the
PC continue working for some seconds when the RAM crashes? Turn the TFTs off when the RAM
crashes?

Wouldn't be a problem to switch the GPU Fans or to install new RAMs / install a fan on the RAMs
but I'd like to be sure that it fixes the problem before I pay $$$ for new hardware.

See if you can borrow a power supply.. random reboot issues, if not heat related, always lead me to think of faulty power. Perhaps your videocards were trying to draw more power than available, and they shut down just before the rest of the machine?

another shot in the dark...

i'd double check the contacts between my fan and the gpu. get the 90% alcohol, gauze, razor blade and the artic silver compound ready.

[beyond-tec]

yay!

my system keeps on crashing but it looks like we can stop shooting in the dark.

I've deactivated the Windows reboot option to force the PC to crash instead of rebooting.
And finally I've had the mighty BSOD (Blue Screen of Death).

Attempt to reset the display driver and recover from timeout failed.

*** STOP: 0x00000116 (0x86E7C510, 0x8E501E80, 0x00000000, 0x00000002)

*** nvlddmkm.sys - Address 8E501E80 base at 8E4F6000, DateStamp 48ebd52f

my GFX Card:

XFX GF8800GTX XXX
NVIDIA GeForce 8800 GTX, 768 MB,
384 Bit, PCIe x16

I've updated my gfx-drivers - let's see if that fixes the problem.
if not, I'll try to get a new power supply and if that doesn't work I'll change the gfx card.
