My pc dies after functioning perfectly fine for 3-5mins HELP!!

post #1 of 14
Thread Starter 
Hi all,

My pc 'dies' after functioning perfectly fine 3-5mins after getting into win7. You can surf the web, play games, bascially do anything for those precious minutes until this happens:
1: It starts to respond slower and slower
2: Individual windows give you that 'not responding' message
3: Only the mouse is working with that 'working on it' circular blue symbol
4: The pc hangs(only got that fatal blue screen twice)
5: Then the system reboots itself i suspect its the motherboard feature, only to that the reboot hangs by itself.

The above procedure has been happening repeatedly for at least 5-8 times.
Tried it at system default values but to no success.

Am using: i7-950 with H70cooler/ Asus Extreme Rampage III ROG / 12GBRam 6X2GBpieces/ Sapphire 6950 120GB CosairSSD/ Samsung 1TB HDD/ WD 320 HDD. 01X 500GB external hdd. Win7 is on my ssd drive.

My own tried solutions:
I have tried switching Sata ports but same error occurs.
Tried system restore but same error.
Unplugged ssd from setup, installed win7 on wd320gb but on reset, post/bios says boot manager cannot be found???? Bios will not attempt to launch win7 from the hdd even if detected in bios. Priority boot devices have been set to force to read from it and still same error occurs.

My observations:
Bios sometimes takes an unusually long time to detect my sata drives during post?? As long as 45secondsbefore it checks the next sata drive. Sometimes it hangs there.
Somewhere during post, theres this funny msg that says no hard drives detected(yes AHCI mode is enabled) but as earlier mentioned, was able to get into win7 on my ssd.
Have had this setup for around 6 months with no problems. Prior to this, i did have had my pc turned on overnight to download some stuff, came back home from work and this happened.

Tried to be as detailed as possible so as to give a clearer picture.

Conclusion: is it my motherboard that is the problem?
Do appreciate all suggestions thank you!!

I think it might be your ram. Can you try testing each ram stick to check if one is defective?

Try booting with just a single stick of RAM, see what happens.

RAM/HDD are suspect, but you make no mention of power supply. This is often and indicator that it's a bad one...

RAM can't work if it's being supplied bad power

sounds like a hdd could be on the way out, got another you can install onto to test this theory? use WD lifeguard to check the WD drive if thats the OS drive or the samsung too; to test the sammy drive if thats the OS drive

well fill out your systems spec in control panel.
Next Clear bios setting back to stock.
Put ram timeing and voltage in bios.
Linx cpu stress is good to cheack stability in cpu.
Prime 95 small fft is nice for ram stability.
what over clock are you using , up the qpi volts, and or core volts.
Watch temps coretemp.

Hi, thanks for quick replies.

1 ram stick is bootable up till when it attempts to launch win7 when d same message:
Bootmgr is missing
Press ctrlaltdel to restart
Im guessing its the same error.

No way to test hdd but my ssd had weird errors mentioned .

Power supply is 850W Thermaltake.

Not touched my h70 cooler(cosair water cooling) for last 6 mths; its a self contained package, so shouldn't be a leaking issue??

Bios setting is stock atm at default 3.06Ghz
Cpu temp: 41.5 C/ 107.5F
Cpu voltage: 1.263
Cpu pll voltage: 1.812
Qpi/dram core voltage: 1.508

IOH temp: 60 C/ 140F
IOH voltage: 1.164
IOH PCIevoltage: 1.508
ICH temp: 59C/140F
ICH voltage: 1.11
Ich pcie voltage: left at default auto setting.

Only changed AHCI settings just to enable the sata hdds atm.

Sounds like a hard drive issue to me. The problem starts after it has to access a certain file(s) which would account for the few minutes of working fine. I've had mine do this before, with the programs not responding and the swirling icon constantly, like it is trying to do something. Ended up being a bad SATA cable. So my guess is cable and/or HDD.
