My computer has a problem that is beyond my ability to readily identify and I hope someone can me help figure it out. The problem presents itself in two separate ways which I assume are related. The computer will crash with a blue screen momentarily flashing that I am not fast enough to read, and then the computer does a full reboot. When the reboot is complete I get a window that says an error log was created and asks if I want to send an error report. The second symptom is a lockup of what ever program I am working in and a window opens up stating there has been a system error and it asks me if I want to send and error report. The failures occur when working with Word, Excel, Outlook Express and Internet Express. Sample of error message: BCCode : 1000000a BCP1 : 81ECF448 BCP2 : 00000002 BCP3 : 00000001 BCP4 : 804DBC9A OSVer : 5_1_2600 SP : 2_0 Product : 768_1 The hardware is as follows: MOTHERBOARD = MSI P4MAM with P4M266A chipset Intel 478 CPU socket) RAM = Mushkin Basic Green 184 pin 256MB DDR PC-2100 CPU = Intel P-4 2.26GHz, 533MHz FSB, 512K L2 Cache OS = Windows XP home edition It does not appear to be heat related since the air blowing form the cabinet is just above room temperature. I have a ZALMAN CNPS7000A cooler fan with a large heat sink on the CPU as well as an added exhaust fan (plus the power supply fan). I can turn the system on and let it run for a day or two and have no problems and sometime it starts acting up after only a few minutes. The problem appears more often when I try to do multiple things at once or do things quickly like close a window while saving a file etc. There is also an ArrowMicro Card Reader, SAMSUN 40GB IDE hard drive, TOSHIBA 16X DVD/RW optical drive and D-link Wireless Ethernet card installed. Any suggestions on what I should do to try and isolate the problem or get more info to help troubleshoot this problem?
