Win7 IRQL not less or equal

Hi everyone, I'm not sure whether this is the correct section for this. If not mods- feel free to move it.

Firstly, system specs;

OS - Win7 64bit, from OEM disk
Mobo - Abit IB9
CPU - Intel Core2 Duo E4500 (Conroe)
Ram - A-data 2 x 2gig 800mhz DDR2
Gfx - Asus EAH 5850 1gig
HDD - Generic sata 2tb rotary
Optical - Sata Dvd RW


Overview;

This system was originally intended to be a budget gaming system and has been serving that purpose perfectly for the last 18months. The hardware, with the exception or the 5850 was purchased about 4ish years ago and while not cutting edge worked fine, I have been able to run EVE, Warhammer Online, BFBC2, CS, Dawn or War, DOW2, The Witcher, and various others at reasonable fps 50+ at the higher settings without the system seeming to break a sweat.

Problem;

I recently purchased Chivalry: Medieval Warfare on steam during a daily deal. I played the tutorial which ran smoothly although the framerate seemed a tad lower than usual. I played a few games and it was only when I joined a 32 player server with a lot of visual effects I noticed a drop to horrendous FPS. Loaded up fraps to confirm I wasn't lagging out and sure enough, average was 10-15fps. Upon checking the system requirements I notice the CPU is below minimum spec (mine is 2.2, required is 2.4).
"No problem" I think and reboot to enter the overclocking features in BIOS, I managed to get a stable system running at 2529.84MHz, which happily ran prime95 for 18hours and only got moderately hot (57c or so) with stock cooling.
I was at work the following night and during a break decided to remote into my desktop to check for any updates on steam/from windows. Steam helpfully (or so I though) offered to update my drivers for the graphics card, and I clicked 'ok'. Upon returning from work I rebooted the system and after the 'loading windows' screen I hit a BSOD.

Reading through the BSOD messages, there was no mention of any drivers at the bottom and nothing overly helpful in the numbers at the bottom. Armed with the knowledge that this error usually shows up when you change something and tends to be driver related, I rebooted and killed the overclock values back to default then booted into safe mode and used Driver Sweeper to clear the old drivers then rebooted - BSOD.
I load safe mode again but this time I remove the Graphics card from device manager and wipe all drivers before going to the ASUS site and grabbing the latest drivers (and previous set for the future). I start installation of the latest drivers but this fails as safe mode cannot load the detection software... The same problem with the older set of drivers..
At this point I resigned myself to the fact that something is seriously FUBAR so copy all my files off the drive to a spare usb HDD I have.

I decided that a fresh install was the way forward so created a bootable disk with DBAN on it and just let it crunch it's way through the drive - 33 hours later I have a completely wiped drive.
I insert the Win7 DVD and change the boot order in BIOS. Windows shows 'loading files' then 'loading windows' before presenting another BSOD... :mad:

I headed over to my local maplin and grab a new OCZ Vertex Plus R2 60Gb SSD as a boot drive for 2 reasons. Firstly I fear DBAN has not completed it's job and secondly, when I need to wipe the OS in future (for whatever reason) it doesn't take 30+ hours.
I install the SSD and disconnect the old HDD, reboot with the Win7 DVD in the drive and following the same pattern as before it displays the all too familiar BSOD with no information.

I began to suspect a memory leak based on a thread I found in a google search. Swapping out the RAM gave the same error, also clearing CMOS didn't help.

The only thing I haven't tried at this point is swapping the graphics card (no onboard GPU on this mobo), I do have a spare but it's a basic VGA card with no graphical power at all - years old.



Diagnostic Data;

- I do not have a copy of the dump files as I didn't think I would need them. - I cannot access safe mode- unless there is an option on the Win7 disk.
- Nothing obvious was showing up in the windows event log.
- Memtest ran for hours but did not error.
- SFC did not find any problems.
- I have a copy of the BSOD but as I say, it shows next to nothing - only thing that may be of use is the series of numbers at the end:
stop 0x0000001 (0x00000000000000002, 0x00000000000000008, 0x00000000000000000)


Any advice anyone can give would be massively appreciated as this is becoming a real pain.

I will try swapping the card now and will post results shortly.

Spare graphics card installed (Trio64v2/DX - generic plug and play PCI card) which is known to be working as was pulled from my server. On 1 (older) monitor I get an 'out of range' message and on the second (18months old) it just shows a black screen but is detecting a signal.
Still able to see BIOS and failure messages with the 5850 installed.

I have no other spares easily accessable now so any ideas are welcome.

Thanks in advance.

Another quick update;

I have checked google for solutions and found 1 site that recommended disconnecting/reconnecting everything - CPU, ram, drives, power connectors, and even went as far as doing the fpaudio/usb cables but still not having any joy.

Any ideas?

Thanks.

im not knocking the system in use either, just the game, the only way your going to get it to work is drop the settings etc and spend a little at least.

your cpu and ram is now to low for this sort of game, no matter what you tweak, a little boost in cpu speed wont help much either as not only is it dual core but a slow one at that.

tbh you have well got pasted the had the money out of it stage without any major upgrades, putting in another better vga card would help a bit same as more memory as your running a 64bit o/s with only the min of ram at 2gb, swap that to 4gb and a different card lets say a cheap 2gb one and maybe, maybe it will last another year unless you pick another latest game to play.

more ram second hand will be very cheap, 2gb at around £10 / £15 max

Sapphire HD 6570 2048MB GDDR3 PCI-Express Graphics Card card also cheap, seen them at less than £50 new for a 2gb version etc

or save your money and if you can replace the whole lot as in the end that's what you would need to do to play modern games like you have picked im sorry to say

Thanks for the input zakblood, but I think you may have misread my OP - system has 4gb ram in 2 x 2gb sticks.
Chivalry was running ok on medium with 65 fps in menus and lowest I saw was 28 on the same server that was unplayable before the overclock. I am no stranger to playing games on lower graphics settings and Chivalry looked fine to me on medium. I know I need to upgrade at some point but that is not an option at the moment. I will have a look around at what components are available at the moment and maybe make a purchase (or several) depending on how things are looking at that time.

What I hoped to achieve by posting here is a system that works again - at the moment I cannot even get it to successfully boot. I am really stuck for ideas now as I cannot get windows to complete installation regardless of what hardware changes I make.

Anyone else care to have a shot at the problem? Or is a local pc shop my only hope? I would rather avoid them due to bad experiences in the past but if no one else has any ideas about this particular BSOD I may have to..

Thanks

Out of interest, have you cleaned the heatsinks and checked all fans are running? (on both CPU and gpu) also can you test a different psu preferably one with a higher power rating and newer if possible.
 
Solved this riddle now but I'll answer your question BigBoy - I cleaned all heatsinks, all fans are running, heat spreaders are clear and making proper contact. The CPU fan has been reseated with new (old) compound. I didn't have another PSU to hand.

Now, the actual solution;

I had a bit of spare time earlier today so thought I would have a look over the entire bios for something simple. OC had been rolled back, boot order was correct, everything was detected, voltages looked fine, RAM timings are....WTF?

Apparently this MOBO thinks really tight ram timings are 'fail safe defaults'. I set that back to auto, hit save and rebooted. All now working fine, windows installed and no funky behaviour since.

I'm miffed that I didn't spot that earlier but keep telling myself I was so caught up in the problem I didn't see the wood for the trees.

Thanks for the helps folks.
