BSOD's are commonly caused by dieing power supplies, bad memory and failing hardware. If you haven't messed with the bios, or added or deleted and files or programs, you can start troubleshooting your memory and your hard drive

the power supplies in Enlight 400W, a very god one.
with BIOS I don't mess up
memory is Geil 2,5-4-4-8 dual channel kit with 97 months guaranty left and was tested in DOS mode with memtest for over 7 hours with no error

I analyze the dump with WinDbg:

DRIVER_CORRUPTED_EXPOOL (c5)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is
caused by drivers that have corrupted the system pool. Run the driver
verifier against any new (or suspect) drivers, and if that doesn't turn up
the culprit, then use gflags to enable special pool.
Arguments:
Arg1: 0110070e, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000001, value 0 = read operation, 1 = write operation
Arg4: 805446f3, address which referenced memory

I think it was from USB no name camera, it is now uninstalled, I have to test and see if BSOD reapears.

p.s. sorry for bad english, I'm romanian

One miniudmp is insufficient to determine the culprit. Zip more minidumps and attach the zip file here. Bugcheck C5 is usually related to fautly ram. However I cannot confirm unless you provide more minidumps.

the problem is not from USB camera, i've uninstalled the drivers but now I have another error: Probably caused by : ntoskrnl.exe ( nt+59e01 )

Yours windows is crashed random and this is the symptom of hardware error. Probably the culprit is faulty ram. Reseat the memory to another memory slot and clean the dust inside the memory slot. If it still crashes, run memtest to stress test the ram.

I first begin with a thanck you for help.
I attach a image with a test ram from ms-dos (Hiren's CD boot) with memtest v.1.65
as you can see this test is standard with 11 pass and over 5h continuos test with NO errors.
before this test I have reseat the memory and another BSOD apears.
what next?

Some faulty ram can pass memtest. If you have ram at another PC, swap the ram and see what happen.

I have some Kingstone's at my brother computer, one 512 an another of 256Mb. let's swap and test ... get back with results in 2-3 days. 10x!

p.s. with original memory (Geil) my computer was tested another 5 h with burning test Everest and no errors, the BSOD apears when computer is idle, after welcome screen about 1h. after computer warms the BSOD don't apears ...

WiTH your Help, I have found THe problem. IT waS THe VolTage for ram. I HaVe manualy SeT and now iT iS ok.
... STupid keyboard...

Do you mean you overclock the RAM?

this is the ram: http://www.geilusa.com/proddetail.asp?linenumber=36 - CAS 2.5-8-4-4 (GE5123200BDC & GE1G3200BDC), in BIOS now it's set to 2,60V and no more BSOD for 3 days now. with default and above 2,70V i have BSOD very often. this error I have only with my new ASUS A7N5X mobo, with the old one Gigabite K8NSC I have overclock the AMD 3000+ venice & memory with no errors like this:
Multiplicator HTT: 3X
Multiplicator CPU: 9X (default)
FSB: 267MHZ
Memory timings: 2-3-3-7 (CL-RCD-RP-RAS) (default)
Command rate(CR): 1T
CPU Voltage: 1.400 V (default)
Memory Voltage: 2.500 V (default)
CPU/DDR Ratio: 2/1.5
Temperatura max:
- Idle: 29-31
- Full: 38-39
I think this new mobo is worst then old one, I do this "upgrade" for PCI-E, now I am very sorry beacause with this one I can't do any overclock.
Now the sistem it's perfect stable but I don't have de performance like I want...
