Two Problems that are possibly related, Crash after sleep mode

[MadforitSteve]

Over the last couple of months my computer has been set to go into sleep mode if it is left for more than 30 minutes and for the most part it works just fine.
The problem that sometimes arises is that when I try to wake it from sleep mode it just hangs on a black screen which I am thinking that it crashes and goes into sleep mode from this state.
The only way that I can go anywhere from here is to completely shut the computer down by holding the power button which I really don't like to do unless completely necessary.
I have done scans with MBAM and SuperAntiSpyware and cleaned what was there which was mainly unused cookies but no spyware or anything like that.

The second problem may or may not be related but seemed to start happening around the same time,,It is not really anything that causes a problem as such but just a little annoying,,What happens is that when I initially start my pc it seems to take a long time to go through it's initial tests that it does,,It doesn't display the POST test but I think it is this that is taking the time,,I haven't changed anything hardware wise and the software is pretty much the same as it was before these problems started to happen.

I hope someone can help me get to the bottom of these problems.

Thanks in advance

could be bad RAM. Can you follow this tutorial to check it?

the second thing hints at a hardware problem. Can you post what is the entry that runs for the most time? (the line that remains the last of the stack for a lot of time before it writes another line under it)

Hello Steve, I would get CCleaner from piriform.com (freeware) and have it analyze your registry, back up the registry before doing anything, though. [it offers to back it up when you try to fix issues, say YES! ]
