Stop 7A and Stop 77 BSODs

[hayt]

I recently built a new system with the following specs:

AMD Athlon64 X2 5200+ AM2
Foxconn C51XEM2AA AM2 Mainboard 590 SLI
1 Gig Kingston Hyper-X DDR2 800 (PC2 6400) RAM
XFX GeForce 7950GT 512MB GDDR3 PCIExpress X16 Video Card
2 Wester Digital Caviar SE16 320 Gig 7200RPM Sata 3Gb/s HDD

I am using an old IDE dvd-rom drive for now, and an old 600 watt powersupply that is only a 20 pin (Mobo supports 24)

loaded a new copy of XP Pro SP2 as the OS, loaded some games, everything ran great, but sometimes (and random) i get critical stops. the do NOT add logs to the event log NOR to the minidump. the most common BSODs i get are 7A and 77. they will sometimes say ntfs.sys or mountmgr.sys. i have searched all over, and am at a bit of a loss as to why this is happening. here are some recent errors and the paramaters:

stop 7A (0xC0708020, 0xC0000185, 0xE1004C08, 0x366BD8C0) ntfs.sys

stop 7A (0xC07BB088, 0xC0000185, 0xF7611000, 0x00A27860) mountmgr.sys



PLEASE SOMEONE HELP ME!!!! i will gladly name my first born after you!

Common causes of stop 7A's are hardware related.

You really should be using the correct PSU.

You should check the RAM is OK using - say - memtest86

You should check the HDD has no issues with say chkdsk /F /R /V (run XP CD in recovery console - or from command prompt - but permit schedule on re-boot)

Better would be spinrite from grc.com - but it costs.

I would expect one or both of those diagnostics to reveal hardware issues.

Please report back.

I have been known to be wrong.

mem check found nothing.

chkdsk found nothing.
