求助！运行时报错！

碧城仙

在QQ分布式群上的朋友求助：
测试Prime95时停止，自己没有超频过，P3  550MHz, 192MB 内存，
报错提示：
FATAL ERROR: Rounding was 0.499
9961853, expected less than 0.44
Hardware failure detected,consult stress.txt file.
Execution halted.
问问该怎么办？

我翻译一下：
致命错误： 舍入是0.499
9961853，期望少于0.44。
硬件发现失败，请参见stress.txt文件。
实行停止。

At some point during the calculation the calculation was corrupted.

Either it was because of a hardware issue: RAM, CPU, MB, PSU
or a software issue: some other program (user application, device driver, OS )
has affected/disrupted the calculation.

If it affects Prime95's calculations it probably affects other programs
ie Spreadsheets, TAX calculation, CAD etc.

Hardware :
If the CPU gets too hot
CPU fan/heatsink coated with dust, fans not working/failing, air inlets blocked,
room too hot (unlikely), thermal paste between CPU and heatsink dried out or not sufficient.
Support chips/MB
coated with dust
Power supply
not supplying correct voltages, too many other devices drawing power,
PSU failing.
PC not getting good electrical input ( spikes, surges, brownouts, noise)
RAM
RAM has errors, static shock corrupted contents of memory.

Software :
some program is affecting the FPU, either modifying flags/precision mode or
corrupted values ( MMX used without proper saving of complete FPU state)


To test
Software: try running in safe mode without running any other user applications.
(many devices drivers are replaced with a generic windows device driver)

Hardware: (turn off PC first) clean out PC (blow out dust), clean off fans,
make sure air inlets not blocked.
Use good surge suppressor or even better a UPS (uninteruptable power supply).
Test RAM with a memory testing program.

What version of Prime95 are you running ?
What OS ? Windows 95,98,98SE,ME,NT,2000,XP,2003 or Linux
Stress testing or running a Lucas-Lehmer/Double checking test to try to find a Mersenne prime ?


大概意思是硬件过热，与其他软件冲突
解决办法：在安全模式下单独运行PRIME95
清理CPU风扇或更换
用其他测试软件测试CPU和MEM的稳定性

我看是内存问题

为什么说是内存呢？因为偶以前过用也是一条64，一条128，由于功率不同，出现了信号不一样，出错率也不同，一但用了稳定性很高的nt系统后，就进不去，或是很快蓝屏

2楼： 用软件翻的？

呵呵，机器加人脑。

不知道楼主的机好了吗？

我在QQ上告诉过他了，但他在QQ群上只是对我们答疑的人说谢谢，没有提及好了没有的事情。
