The computer has rebooted from a bugcheck. The bugcheck was: 0x000000d1 (0x02472005, 0x0000001d, 0x00000001, 0x77f53b35). A dump was saved in: C:\WINDOWS\MEMORY.DMP. this happens daily, please help me :O

You may have a bad power supply - it will shutdown your computer at random causing Windows to do a memory dump and reboot.

The same thing happens to me when i startup and get to the logon screen, it reboots, and I find another entry in C:\WINDOWS\MiniDump. Could this be cuase by an underpowered PSU as well? Dell Dimension 4600i Windows XP Home v2002 SP2 Microsoft Office 2003 Pentium 4 @ 2.8GHz 512MB DDR RAM 40GB HD ...If my computer's not happy, I'm not happy.

Yes, if the power supply is going you may find that your CD's don't spin as fast as they should, your hard drive may slow down or you may just get spontaneous reboots. A power supply is at least a cheap thing to fix - just make sure to buy one with enough wattage for the components you have installed.

i had bought a new PSU around august/september, 520W Aspire, my system isnt slow or anything. it gives me the blue screen saying DRIVER_IRQL_NOT_LESS_OR_EQUAL and u know its a driver problem but i dont know which, i cant open the dump file because its 511mb and it freezes wordpad. ive been getting the same error for a year now, i revamped my computer ENTIRELY except for the audio card and it still does this. its so annoying because i have school projects to do and it just goes BAM! and messes up ;|

One of the options when you press F8 for boot up options for safe mode is to view it "logged mode" or something like that - it displays each step of what the operating system is doing and it will hang at the driver that it is having problems with just before displaying the blue screen. Write down the name of the driver it stops at and look it up to see what is the cause of your problem. It is likely a corrupt driver or the wrong version of the driver.

The bugcheck parameter 2 is x'1d' which is system level IRQL which is unlikely to be a software problem. It must be hardware problem such as faulty ram, cache memory in the mb or cpu, bad psu. Most likely the problem is at motherboard. If the IRQL is 2 or ff, it may be software error. Hope it can help you.
