M1730 hardware problems

Hi,

I brought a XPSM1730 back in April 2008 (2.5ghz dual core/4gb ram/8800m gtx SLi), the warranty expires in April '11.

Yesterday when shutting down I had a blue screen crash that said:
"Hardware Malfunction , NMI: Check Parity/Memory Parity Error" and couldn't switch the laptop off, had to wait for the battery to die.

So far today the laptop works fine.

Also the battery light (below the power light) is flashing orange. Even though the battery still charges I believe this flashing means the battery can't be charged.

Lastly and this issue has been going on for a few months. The logitec LCD screen (the thing that can display performance/clock/stopwatch etc) sometimes flips out and the display goes out, (have to task manager-end LCDmon to reset screen) though this happens randomly.

I take this as a sign that my laptop will die soon of some hardware problem sooner or later, is it the motherboard? or perhaps the memory/gfx that will die soon.

I have had a few occurances with the gfx card overheating, though it seems to be working fine at the moment.
