Computer Lockups in Windows XP

[Greatbacon]

The Story So far:

Okay, so on Tuesday somehow my computer got infected with a virus.  One of those programs that makes up fake viruses and stuff to claim your computer is infected and sell you their bogus virus remover.  I googled around, found Malwarebyte's Anti-Malware was the common solution, downloaded it, ran it, and purged my system.  Everything was fine and I'm not even sure if this scenario is related to the problem, but I figured it might help.

The next day I got bored and decided to fiddle around with bblean the alternate shell... thing.  I got it running, configed, etc., my computer was fine and I went ahead and set it into standby for the night.  In the morning when I reactivate my computer, all I had was a black screen and cursor.  I went ahead and resetted, my computer boots up fine, and ends up in the explorer shell, just as it was before i set up bblean.  Then the trouble started.

So far the lockups seem to be fairly random.  Whatever is on my screen stops moving, including the mouse, I can't alt-tab, ctrl-alt-delete, or anything else that would exit the program, and if there's audio running in some area or another, it will also crash and loop about the last 2 or 3 seconds of sound.

I've had lockups while running TF2, both in various combat situations and after pressing the disconnect and quit buttons.  Watching video in winamp has locked up, as well as just music in the background while surfing the net on Firefox.  It's even locked up while going into standby mode, at the the screen that says "System shutting down". 

Also, after startup, when all the initial stuff loads and I'm ready to go, if I press start or mess with the docked items bar, explorer is fine, but so far if i press the quicklaunch button for firefox or winamp, the shell disappears for a few seconds, then comes back.  It hasn't done this for Ventrilo though.

I thought it might have been related to my graphics card, so I updated to the latest nVidia drivers, but so far they haven't helped any.

Any thoughts, tips, deus ex machina solutions, etc. would be greatly appreciated.  Thank you.

EDIT:  Just now, I was surfing about the internet, listening to some music when the telltale sign of a lockup, audio looping, happened.  Oddly enough however, I was still able to mess around with the page I was viewing in firefox.  Little buttons would change as I moused over them, even the ones down in the taskbar.  As soon as I clicked on the winamp tab and then the exit button on firefox though, it all went to shit.  Still don't know what this means.

Cool, finally got a blue screen today.  "IRQL_NOT_LESS_OR_EQUAL"

Looks like I got some confirmation on what i was afraid of, an overheating CPU or some bad ram.

Tomorrow I will do science to it.

Do you have anything plugged into your PCI-E/PCI slots other than your video card?

Nope, the only thing in there is my video card.

On another note, I tried running my computer with the case open and a fan blowing on it, and the computer still locked up, so I suspect it has more to do with RAM than the CPU.

Not sure if the RAM is faulty though or if I still have some malware or shit on my computer messing stuff up.

If you have multiple sticks of RAM try booting with one of the sticks, interchange sticks and slots if you continue to have problems, an IRQ error usually means that two components are on the same IRQ channel and conflict when polled by the processor. This usually involves some PCI cards sharing a slot (at least in the past it did).

RAM blue screens usually come up with 0xc00000310813 and some other hexadecimal garbage that constitutes the address where the memory fucked up

I got that error from a similar virus a while ago.  Reformatting fixed it.

Mkay, I've been leaning toward this solution for a day or two now, mostly I've just been putting it off cause I can't find my XP disk.
