BugCheck event id 1001 and Kernel-Power event id 41

Experts, thank you for reading

my windows 7 pc keeps rebooting. when left idle for few hours, it crashes. in event viewer I see bugcheck event and then critical kernel power. there is memory.dmp and minidumps so I tried to install SDK for win 7 but installation fails.

another user with window 8 pc starts with same problem with his laptop reboots like 3 times in an hour

I don't know where to begin, how to determine the cause of this? please Help.

BugCheck event id 1001:

Log Name:      System
Source:        Microsoft-Windows-WER-SystemErrorReporting
Date:          10/05/2013 08:25:40
Event ID:      1001
Task Category: None
Level:         Error
Keywords:      Classic
User:          N/A
Computer:      P28
The computer has rebooted from a bugcheck.  The bugcheck was: 0x00000050 (0xff900098, 0x00000000, 0x82a0430c, 0x00000000). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 051013-17628-01.

Kernel-Power event 41:

Log Name:      System
Source:        Microsoft-Windows-Kernel-Power
Date:          10/05/2013 08:25:25
Event ID:      41
Task Category: (63)
Level:         Critical

User:          SYSTEM
Computer:      P28.domain.local
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

several things to look at:
are the machines dust free and fans all spinning ok?
all service packs and patches?
run an app like Ccleaner to kill all temp files etc (wont fix it but will help speed up the diagnostic process)
Run malware bytes and do a spyware scan
I would guess it is just a coincidence with the two machines.
Change memory and/or graphics cards if this is possible.

my desktop pc is 2 yrs old so it must have dust in there. the windows 8 pc is a 2 weeks old sony laptop.

on my win7 pc, windows update up to date, I use regcure pro so scanned and cleaned, did windows defender scan and Sophos scan with no infection reported.
i'll open the desktop pc and check if all fans are running

all 3 fans running ok

Please provide at least two ZIPped minidumps of the same PC. STOP 0x50 is a hardware or driver error; if the minidumps show the same source of failure, it is most likely a driver issue.

regcure deleted all my minidump files. will have to wait for it to crash again. anything else i can do at the moment?
Remove dust, preferably with something able to blow.
Perform the W7 memory test (using the boot menu - press F8 on boot).
Make sure the crash dump is a kernel dump (no mini dump) - see System Properties, Advanced, Startup and Recovery. When there, you might want to uncheck the auto-reboot option on crash, which allows you to see the BSOD with some brief info.
