had another think about this. I did have a very similar issue.twice actually. once was dodgy ram I had to replace, and 2nd time was a dodgy ram slot... ended up replacing mobo. probably good idea to test each of the two sticks one at a time in each of the ram slots (and clean them of dust....)

That actually made me tear up a little.

mhm...

It`sad really, that we in the west allow ourself to bring all OUR junk, and dump it to the east. Computers, plastic bags, shoes, clothes, whole rusty ships etc...

I saw a documentary about a ship yard in India where people were cutting down big ships, even without safety tools.

On the other hand India is a fast growing country, and according to the rumors, are soon getting their first aircraft carrier.

I changed my mouse back to the older one, and the crashes seem to have vanished. What the hell?

I only saw this thread now but after reading your original post my initial thought was going to be the mouse. I've found anytime a pc starts bluescreening I look to any hardware that was changed recently followed by what software got installed/reinstalled/uninstalled before the bluescreens started happening.
Most of the time bluescreens don't start happening out of the blue if a machine hasn't had any changes made to it. Its usually a hardware or software change or even a driver update that causes them to happen.

Most likely its a driver issue with the new mouse that your pc doesn't like. You can go look for a updated driver online and try that. If thats not an option, I'd continue to use the old mouse and think myself lucky I don't have to reimage my pc or worse, buy a new one.

Hmh...

Yesterday I splashed the cash and finally bought the XBOX-controller for my PC. It installed itself just fine, but today the crashes started again. It may be related, it may be a coincidence ?

I'm starting to think it may not be the mouse that was killing this comp after all. Can it be the PSU ?

My PC used to reset without reason or warning and freeze before loading windows. I tried running with one half or ram, the other half, no video card (used the mb builtin one instead), no cd-rom, nothing corrected the problem. Luckily I had a PS sitting around doing nothing so I switched power supply and the problem was solved.

The symptoms seem like a power issue. I had a board that acted just the same. So after looking into it I had some bad power capacitors on there. Your board seems to have the newer solid caps though so it probably isn't that. I would look at your power supply with a multimeter if possible.

I'm no genius, but I'll take a look at the minidump file for you if you like. Sometimes they can be useful! PM me if you're interested.

if you have 2 memory slots occupied free one and see if it works better, and change with other ram after

you'll be surprised how i solved pc's with only that :)))

Best thing to do is to run bare minimum for a while to see how things work.
If you have two graphics card, run one. Remove all but one memory stick. If you have any add-in cards you can do without remove them. Remove any extra USB Devices, such as printers, gamepads, scanners. You said something about physx, so, if you have one of those cards remove it. Add in sound card...remove.

After reading the thread fully, I noticed after you removed the new mouse it stopped crashing, but you bought the gamepad and it started crashing again. Are you plugging the gamepad, new mouse, and old mouse into the same USB port? Which ports are you plugging them into, the one on the front of the case or the ones in the back on the motherboard? Are you using a USB hub?

I have a USB hub, but it's not plugged in. I did plug this new mouse into the same usb port where it did crash prior to the complete re-install. It did not crash after the install until now, though. Do you think the problem may lie with the USB ports? The mouse is plugged in one of the back usb thingies.

The gamepad is plugged in on the front USB port.
