求救!!!!

我的电脑以前是出现蓝屏幕如下

If this is the first time you＇ve seen this stop error screen, restart your computer. If this screen appears again, follow these steps:
Check to make sure any new hardware or software is properly installed.
If this is a new installation, ask your hardware or software manufacturer for any windows up dates you might need.
If problems continue, disable or remove any newly in stalled hardware or software.
Disable BIOS memory options such as caching or shadowing.
If you need to use safe mode to remove or disable components, restart your computer, press F8 to select Advanced startup Options, and then select safe Mode.

前几天严重了.开机无法启动XP,重装后,还是无法,有时要自动反复-4-5次才可以.
    内存条换了试过,也没有用.
    敬请朋友们救救小弟,，多多感谢！

个人感觉可能跟供电有关,建议重点关照CPU及内存周围的大一点的电解电容!!

我的也出现过，是串口硬盘的问题，更换硬盘正常

主板坏了
