Solved: rep

hp 7800 WIN 7 has a blue screen BAD POOL CALLER 0x000000c2 error and won't boot. I have reseated the memory boards, and reset the IMOS, and removed/reset the battery all to no avail. I cannot find any way to disable the BIO caching/shadowing as suggested. I have tried to rebot with the win 7 disc, but no luck. Anyway suggestions on how to boot, or fix the BIOS?

 

Can you boot in safe mode?

 

No, I can't boot in any mode, and I have tried multiple times in both regular and safe mode.

Yes, I bought it as a refurbed system about 1 1/2 years ago and it has been working great until now. I did load turbotax on it a few days ago which worked fine until I shut it down for the night and then restarted it the next day, so that may be the problem.
If I could get it to boot I could remove the program.

 

If you can boot from a diagnostic disc, complete hardware testing of the hdd and memory

 

Even with the emergency repair disc I can't get the system up beyond going into setup (f10) at startup. The memory test ran successfully in that mod. The first blue screen says Bad Pool Caller, and then says to disable BIOS memory options catching and shadowing, but I can't find a way to get into the BIOS other than a power on screen with days of the week.

 

I reran the memory test from system setup and found a bad memory module in slot 3. Once I removed it the system booted and came up although a bit slow. I will buy a new module and should be back to normal. Thak you all for your support!
