my pc keeps restarting randomly after a few hours (BSOD) and memory read errors with HL2 & CS:S and other games. Case temps are usually 30c, CPU 50-55c (not o/c) never above 60c. RAM sticks have copper heat spreaders, CPU has Zalman CNPS6000-Cu with artic silver compound. Case has two fans (top and side) and front and back vents/grills so plently of air flow! Any idea why it keeps restarting after a few hours?? AMD Barton 3200+ ABIT NF7-S revision 2.0 Kingston 1GB 400MHz Dual Channel

Weak psu? Bad memory? Use memtest to check your ram.....http://www.memtest86.com/#download0 What graphics card do you have? Whats the amperage on the +12v rail of your psu(sticker on the side) Tt Lanfire nf7-s v2.0 XP-m 2500@210x11 SP 97 512mb pc3200 Jou Jye 550w psu FX5600 WDCaviar 160gb sata WDCaviar 160gb sata ;~}

My PSU is a 400w HI-POINT Memory test came out fine (its kingston value ram btw) Ive got a ati sapphire 9600 (passivly cooled) +12v rail says 18amps Checked voltages with nvidia monitor and they are all normal if the psu is the worry i got 1 hdd, 1 cdrw, 1 dvdrw, soundblaster, pci usb card, tv card, 2 LED fans and the cpu fan, a neon tube, and never more than 5 USB devices plugged in- is that to much for a 400w psu- surely a 300w psu could handle that plus the motherboard etc??

Wattage don't mean that much if there aint no amperage.18a is ok just. Do you have the 4pin molex connector plugged in? What are the memory read errors? Have you checked the event viewer? What ratio do you have the cpu/ram at?Should be 1:1. I found that my soundblaster card added 10c to the cpu heat so I now use onboard sound,which is great anyway. What are the heat threshhold settings at in bios? Tt Lanfire nf7-s v2.0 XP-m 2500@210x11 SP 97 512mb pc3200 Jou Jye 550w psu FX5600 WDCaviar 160gb sata WDCaviar 160gb sata ;~}

4 pin molex is plugged in i would say what the memory read errors were but i havent recorded any of them. On half life its "Memory could not be read at 0x00000..." (000's arnt exactly what it says) etc. As for the BSOD, sometimes it apprently just a random system file (the specified file changes) thats causing the error, or sometimes is comes with the 0x00000 memory stuff again. dont know what you mean by cpu:ram ratio, i dont do any overclocking or changing settings like that in the bios. memory and fsb are at 1:1 anyway if thats what you mean. taking out soundblaster took 10c off cpu?? i will try that- is the onboard sound on the nfs-2 as fast as the soundblaster in games?

try different video drivers personaly in HL2 on my dell inspiron notebook it was crashing every 10 minutes, once i put someone esle drivers (nvidia geforce4-go video card) all the problems dissapear have no idea why i came to this planet

tried omega ati video drivers before, made half life 2 drop by 5fps so i took it off, wernt on there long enough to see if it stoped the restarting. doubt it to be honest. ive disabled my tv card and sound card in device manager and its been fine so far- may have solved the problem....
