My HP Desktop keeps crashing every 10-20+ minutes with no rhyme to reason, So far I have

Run a Spybot, MSE, and Malwarebytes scan (Nothing)

Ran in Safe Mode (No issues)

Opened it up, it was caked with dust , but after cleaning it is still doing it,

This is a pickel. Any thoughts?

ETA: Crashed on me again just after posting this,

Are you fans working? it sounds like its over heating..

Did you blow out the power supply too?

What exactly happens when it crashes? BSoD? What error code/message.

Bad memory does some weird shit man, some weird shit.

Use this:

Or better yet, this includes the above test as well:

second vote for thermal. Look up some system diagnostics. I remeber "speedfan test" or something similiar. I used said program to find bad heat sink thermal bond issues a few times. You will see you cpu heat up and then the fan speed up to cool it. Once your cpu hits it's thermal circuit breaker thresh hold, sleepy sleepy it goes. TT

Took the case off the fans are running,

I can still boot into safe mode, but I cant get in to "main mode" at all so far it has locked up at the login screen, and the last try the screen looked like the something from the matrix.

I'm thinking about disconnecting the second HD and doing the system recovery.

Checked it everything is ok,

Tried system restore,

No dice either.

You have an over heating issue, either its the Video card or the CPU.

I tend to believe its more the CPU. Take it off, clean old thermal paste off, put new stuff on, put it back on and try again.

I had this happen to me once on a 2U server and thats what I found it to be.

I think it is the video card, as the super duper video drivers don't load in safe mode, so some video functionality won't be turned on. whereas any cpu/chipset "drivers" tend to tell the cpu to turn things off, and they don't load in safe mode.
* Of course I'm guessing about that whole thing.

Sound like a lead.

How would I check this?

That may be, but the CPU over heating will auto shut down pretty fast. Plus you can double check that by just unplugging the video, you should get a beep from the m/b.

Also the Video card wont over heat unless its being stressed, if hes just browsing, it wont be doing anything stressful. CPU over heating will shut down/freeze alot sooner than the video card if its not cooled correctly.

Well over heating, bad hardware or power supply gone bad.

What is odd is it won't successfully go into normal mode, but it will for safe mode.

My money would be on the power supply if you've cleared it out and the problem still persists.

The caking of dust could have killed some components in the PSU and its making it trip out.

Any chance you have taken a look in event viewer to see any messages around the time it goes out?

Failed capacitors are likely. Most likely, either in the power conversion near the CPU, or in the power supply. But I have seen failed capacitors on a video card cause similar problems.
