Hi, I have read & tried so much stuff on the following issues and now feel I really need some help. Basically, I keep getting the "Hardware Failure; replace failed component" error. I get this error any time - playing games or just surfing. I checked the event logs which only said "SYSTEM ERROR 1003" I check my cpu temp which is always around 40c so ok. After reading about possible causes I decided to check my ram. I used some spare ram from another pc, swapped, paired, unpaired etc but still got the same issues. I downloaded the latest drivers for my mobo, graphics card, & sound - No Joy Next I decided to remove my graphics card & drivers to test with just the on-board graphics card. So updated the drivers. It seemed to work for about half a day but then started crashing again with the same hardware error. Next I tried changing the IDE cables - still the same. I have also made a full re-instal of XP. Is it likely I have a CPU/MOBO/PSU problem? How can I test without replacing the individual compnents? I know this is long winded but Ive been trying to sort it for a couple of weeks now. Thanks in advance. PC Spec: ASRock K7S41GX 512mb ddr ram (plus various 256 sticks) AMD Athlon XP 2200 Seagate barracuda hard drive NEC dvdr

Once again, the most important hardware item is not listed...the power supply! What is the make/model/wattage & how many amps are on the +12v rail? Is it one of those garbage Bestec units?

Power supply is an etech mpt-400 230v/400w max

Would this still be a power issue though as I previously mentioned I have striped it down and run a barebones system and it still crashes? How can I test CPU/MOBO problems without changing the components? Has anybody got any ideas?
