I have an Acer Aspire 5700 desktop purchased in January of 2010 that is experiencing freeze/crash issues that I can’t resolve. It runs Windows Vista Home Premium, but I do not have the disks. Here are the specs

I had the same issue last year, starting in June, then it suddenly stopped in September, and didn’t occur again until June 21, of this year, and then every day since last Friday.
Shortly after booting, the computer does one of two things:
-the monitor goes black and says there is no signal, and only the blue power light on the tower stays on, or
-the desktop/programs freeze. In both cases I have to reboot from the tower.
In researching similar problems, it was suggested that this was a heat, bad memory, or graphic card issue. I have a temperature check and that shows acceptable temperatures. Plus, if it were heat, it would occur after the computer has been on for hours and not within 15 minutes of booting. Memory tests have been run and confirmed that it was all good. I have checked the seating of the graphics card as well as all cables, and that is not the problem either.
All my drivers are up to date as far as I know. I ran WhoCrashed and here are the reports for two of the latest crashes. It does not show a report for the ones that occurred July 10, 11 and 12:
Crash dump directory: C:\Windows\Minidump
Crash dumps are enabled on your computer.
On Mon 7/13/2015 12:37:20 PM GMT your computer crashed
crash dump file: C:\Windows\Minidump\Mini071315-01.dmp
This was probably caused by the following module: ntoskrnl.exe (nt+0x57150)
Bugcheck code: 0x1E (0xFFFFFFFFC0000005, 0xFFFFF8000291074E, 0x0, 0xFFFFFFFFFFFFFFFF)

Bug check description: This indicates that a kernel-mode program generated an exception which the error handler did not catch.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.

Here are the two BSODs I got, one yesterday and one today:


I would greatly appreciate any insight you might have. I love my Acer computer. I have used Acer desktops since 1996. It is an older model but it does what I want, and that’s the most important feature to me.
