Hello all!

I have a problem plaguing my PC that has got me so, so confused.

Just so you know, stats are now;

Fresh Install Win7 64bit
Gigabyte GA-Z77X-D3H
Intel 3570k @ Stock
EVGA GTX470
8GB Rip Jaws 1600mhz memory
Agility 3 90GB SSD
2x Segate 200GB
Audigy Soundblaster 2ZS
Antec 900

Basically a little while ago I posted this http://forums.overclockers.co.uk/showthread.php?t=18427392 about my computer randomly freezing on boot up and sometimes during the first 10 mins or so.

Now people all said blah blah clearly a PSU problem. So I got a new PSU (Corsair TX750), clearly beefy enough to handle my stats. Yet I still experienced freezes and hangs.

So I finally gave in and went through the lenghty process of RMAing my GPU (it was nearly 2 years old, and EVGA still swapped it for me :)). They sent me a new one with paperwork basically saying the old one failed several tests. Bang tidy I though, this will finally fix my PC.

Wrong. I now have completly different parts in the entire PC from the one that I was experiencing these hangs with, yet I am still having the same problem!

I have tried:
A multitude of parts
Several different houses to rule out housing electrics
Removing my soundcard and front panel completly
Removing both HDDs and leaving just the SSD

How the hell is this possible? There is not a single component that I have not changed to erradicate this problem, yet the damn thing still hangs on boot and freezes when on?!

Anybody with some ideas, I would REALLY appreciate it!
 
Not technically spare, but my old system had different RAM and experienced the same problems. Current RAM is new and still crashes.
 
Will try BIOD update later. Currently both HHDs are unplugged and only have SSD running. Still crashes. System crashed on 1 HDD before I got the SSD. Pretty sure I can rule them out.
 
Have you tried swapping around your peripherals. The USB 3 ports on my board can be very funny about what is plugged into them. It hangs on boot if my joystick is plugged in and it crashes if my wifi dongle is plugged into a USB 3 port.
 
Sounds like you are desperate. So I will add my advice.

Physically remove every single add on card and cable plugged into the system and mainboard! That means running with the intel graphics, no lan, serial ports or extra sata ports or anything like that enabled. Disable every single device you can in the bios. So what you are looking for is to have the ABSOLUTE minimum components activated and installed to boot and use the system. Use it like that for a while and try replicate the problem.

If there is no problem and it's stable add one device or enable just one device and repeat, until you find the culprit.

On the other hand if you are still crashing it's maybe a hardware/driver issue which has now been limited to only a few pieces of hardware.

A different thought though, it could also be 2 different problems...the booting could be bios/hardware related and the other windows related.

Also run absolute standard speeds while doing these tests. With a tricky problem like this don't rule out any device! Even change mouse/keyboard if all else fails.

Also consider removing any custom cooling as it is possible to over tighten some models warping the mainboard and possible causing unreliable behaviour. So run standard intel cooling and reseat mainboard in case while at it.

I know you haven't listed it, but did you by any chance buy a TP-Link Wifi PCIe card from another online retailer for £11-£15?

2 of my friends bought these and had problems very similar to yours..

We found out what is was after playing GTA IV on the xbox, one of them lagged a tiny bit and notice their PC had frozen. The WiFi card seems to make the PC freeze when the connection is dropped and gained again suddenly. This happened on both systems with completely different parts. If you have a PCI/PCIe Wireless card, unplug it, check for stability and report back.

After buying new WiFi cards neither of them experienced the problem again, hope I helped!
