XP PC Freezes - failing hardware??
Posted on 2005-04-30
I posted previously and thought the problem was resolved but it seems to have returned.
I have an Alienware PC bought in late 2001 running Windows XP Pro: P4 2 Ghz CPU, 1 Gb RAM, LSI Logi MegaRaid SATA 150-4, four Maxtor SATA HDDs (200 Gb ea) running in a RAID 5 config.
Recently, my PC started freezing randomly -- while in windows or SafeMode. Froze in BIOS. Froze when booted off a CD. Anywhere! Sometimes my PC runs fine for a while, then after freezing & rebooting, it would freeze up very quickly...again & again after numerous reboots. (overheating?)
Also, sometimes I notice after a reboot, I dont have a NIC show up under Network Connections or Device Mgr. It comes back after a reboot. It's an Intel NIC PCI card (not embedded in mobo).
The last hardware change was made about 18 months ago (that's when I got the LSI card & SATA drives).
Since the PC freezes everywhere, I dont see it being a software or OS problem but hardware instead.
I tested all the SATA drives - no errors.
I updated the LSI card's firmware (that resolved my previous recent problem of showing two drives as FAILED).
My BIOS is on the latest version (although a few years old - nothing newer released).
I tried removing RAM chips (I have 4, they need to run in pairs).
I disconnected all external devices - scanner, printer, ext DVD ROM, ext HDD.
I have the Intel monitor software running that monitors temperatures - they seem fine (in 'green' zone) so that's why I dont think it's overheating but...
How would I be able to check if it's the power supply or the mobo itself w/o swapping? There are no burnt looking capacitors on the mobo (someone suggested to check this on another similar pc freezing post).
Any other ideas? Thanks!!!
