Crash, Crash, Crash.............

[vaporware]

I'm rather stuck on how to troubleshoot this issue:

I'm running WinXP PRO SP1 with an 80 gig SATA HD, OCR 512MB on an NF7-S V.2 mainboard and an AMD 1.8GHz processor. I'm at a point now that in order for me to boot in Normal Mode I need to boot into Safe Mode and do a thorogh chkdsk on all of my partitions. A Normal Boot will only last a short while until somthing causes the system to crash-just power off, with my mainboard sounding an alarm like a European ambulance. There's more-while booted into Safe Mode and running chkdsk sometimes that will cause a crash. When I try to boot from the WinXP CD or when I try to reinstall the OS the system will crash during Install. Of course I can't forget when I try to Defrag, occasionally I'm greeted with a crash as well. I try to boot into Recovery Console-CRASH!

At this point I cannot tell which element(s) is causing the crash. I could easily go purchase all new system components and write this one off-but where's the fun in that.

I have run numerous Diagnostic programs, when I'm lucky to be in Normal Mode, and all come back fine.

I am at your mercy, DaniWeb GODs..........

That motherboard alarm makes it sound suspiciously like an overheating problem. Remove the side of your system case and check that:

* The fan and ventilation holes aren't clogged with dust
* The processor fan is actually working
* The processor heatsink/fan hasn't become loose or unclipped. It should be clipped quite firmly, and resist a light twisting motion.

Everything clean and dust-free, all fans are functioning and the Temp. shows a comfortable Degree after 1 hour of operation. I have gone as far as dismantling and reassembling again without success either.

Check in BIOS Setup on the 'PC Health' menu. 'CPU warning temperature' might be set to too low a level. Motherboard alarms generally mean only either a heat warning or a 'case open' warning.

The other problem, the system crashing (I don't think the two are necessarily related) could well be a RAM problem. I haven't come across OCR RAM, only OCZ RAM, but generic modules often have incompatibilities with motherboards, and cause the sort of system crashes you're experiencing. I'd try running the system with a single module of RAM borrowed from somewhere else. If it runs stable you can suspect your own RAM as the source of the problem.
