The problem is very frustrating: my computer keeps freezing. In other words, the mouse pointer is unable to move, I cannot use the keyboard, and therefore cannot use Ctl+ALt+Del to shut down processes. In order to fix the issue, I need to turn off the computer at the mains and sometimes I notice that the loadingup of windows is slow. At first I initially thought that the issue was spyware related and so to that effect, I reinstalled windows. No joy, the problem occurs even after a fresh installation of windows. There is NO pattern or warning signs associated with this particular problem, it really is random indeed and I must note that the length of time that it takes for my machine to freeze seems equally variable. Ok guys some observations: I was watching youtube and the computer froze (exactly the "same" as it has been). The music I was listening to on youtube died, as if it had been paused along with the mouse cursor not being able to move, or me being able to type. HOWEVER, the curious thing is that I use an infra red mouse and so if it is not connected or if there is no power, then the red light does not appear. The red light was still on even after the computer had frozen. I checked my Device Manager, and all hardware periphals, no errors, yellow exclamation marks or warning flags. I ran CHKDSK from the command prompt in the Windows enviroment, and it reported no errors or problems there either. I wasn't sure as to what info was needed from my BIOS so I wrote it all down: CPU Temp: 90 C MB =44 C CPU Fan Speed= 3947 RPM Cpu Q Fan Control Enabled CPU Fan Ratio: Auto CPu Target Temp=60 C AMIBIOS Version=0501 Build Date= 3/2/03 ID=AOI 64001 Prcoessor: Type Intel Pentium 4 Cpu 3.40 Ghz Speed: 3400 Mhz CPU Manufacturer: Intel Intel Pentium 4 Cpu 3.40 Ghz Frequency=3400 Mhz 800 Mhz Cache L1=16Kb Cache l2=2048kb MAx CPUID Value Limit=Disabled Execute Disable Function=Disabled Hardware Prefetcher=Enabled Adjacent Cache Line Prefetch Enabled CPU Internal Thermal Control=Auto Chip set settings Configure DRAM Timing by SPD=Enalbed Graphic Adapter Priority PCI Express/PCI VCI for AZlica and Root Ports Disabled Azlia Controller Enabled Onbound 1394 Controller Enabled Onbound LAN Enabled Onbound LAN Boot Ran=Disabled Serial Portal Address= 3F8 PCi/Pnp Settings Plug Play O/S Yes PCI Latency TIme 64 Allocate IRQ to PCI VGA Yes Plette Snooping Disabled PCI IDE Buster Enabled Offbound PCI/ISA IDE Auto ACPI Aware O/S Yes Suspend Mode s3 Only I notice that whenever I browse the internet with firefox, firefox keeps crashing: this seems to have no impact on when my computer freezes however. I have checked eventviewer, and I notice that there is a significant number of yellow exclamation marks all stating the same thing: Event 51 An error was detected on device \Device\Harddisk6\D during a paging operation.

"CPU Temp: 90 C MB =44 C" Your motherboard temp is high & your CPU is overheating. Unplug the power cord, open the case, blow out all the dust. Make sure all the heatsinks are dust free & all fans are working properly. You *may* have to remove the heatsink from the CPU, clean off all the old thermal compound & apply a fresh layer of paste. Assuming you have a single core CPU, here are the instructions: http://www.arcticsilver.com/pdf/app...

I ran memtest 86 it always freezes at precisely the same spot: Pass 24% Test 19% Test #5 (Block Move) Test 20k-1024M 1023M using CPU 0 Mem Map e820 Cached 1023 M Rsvd_mem 136k Item 40 Test _Sel Std Cpu_Sel Single ECC_mem: OFF

Your CPU is overheating! 90C is almost 200F...does that seem reasonable to you? The temp (at idle) should be in the 40's C.
