I'm sure this will become obvious, but this is my first post, so please forgive me if I havent followed ettiquet to the letter. Can somebody Please please help! - I have the following Hardware: Windows XP Professional running on: Gigabyte GA-8SRX motherboard - SiS 645 chipset Intel Pentium 4 2.0GHz (northwood) - retail box with intel Fan. 256 MB DDR RAM Segate 60GB HDD 7200 RPM Sony CDRW Creative Blaster Geforce 3 Titanium 200 (64MB) Microsoft Wireless Desktop (keyboard & mouse) HP Deskjet 3820 I've been using the above pc config for about 2 months no problems, then suddenly, I started to get a message on POST saying BIOS WIDE RANGE PROTECTION ERROR (I have the gigabyte dual bios thing) and this seemed to completely nacker the op system with a BSOD and something about missing or corrupt windows files. I restarted several times and finally the PC booted without complaining (with me having done nothing at all to attempt to fix the problem) - This was just the start of my grief: Ever since, I have suffered sporadic re-starts, where XP restarts and says it has recovered from a serious error, reporting it to Microsoft, results in a Knowledge Base article popping up (I think its called windows online crash analysis) saying the prob was caused by a device driver but they cant be more specific) - I Dont think its a driver problem - why has it only just occurred? - but the plot thickens..... Recently, having read a number of posts on this site, I followed the adivce given to people suffering similar problems with the re-starts, and both un-checked the "restart automatically" thing in my computer - performance, I also turned off my page file and then created a new one. The problem has got worse since and here follows a list of stop errors i have had recently some on booting up, and others whilst in XP: Stop: c0000218 {Registry File Failure} The registry cannot load the hive file : \systemroot\system32\config\SOFTWARE or its log or alternate It is corrupt, absent or not writable. ----------- INVALID_PROCESS_DETACH_ATTEMPT Stop: 0x00000006 (0x00000000, 0x00000000,0x00000000,0x00000000,) ------------ BAD_SYSTEM_CONFIG_INFO Stop: 0x00000074 (0x00000003, 0x00000002, 0x80087000, 0xc000014c) ------------- Stop: 0x0000008E (0xc0000005, 0x8056650, 0xf3bf2b70, 0x00000000) -------------- PAGE_FAULT_IN_NONPAGED_AREA Stop: 0x00000050 (0xcb106f45, 0x00000000, 0xcb106f45, 0x00000000) -------------- This is a sample of the stuff I get, freezes on starting XP sometimes, other times, everything stops responding whilst browsing the net - it still restarts whenever it feels like it? SHEESH! - will somebody please help me - why so many different types of stop message? - why the bios error before it went wrong - is the geforce 3 ti 200 crap or have i got a dodgy motherboard? I give up please help??? !!!!!
