Hi,

I bought a new laptop - HP Compaq Presario, Intel Pentium Processor T4300 (2.1 GHz), 500 GB Hard Drive, 4 GB RAM, nVidia GeForce G 103M with 512 MB DDR2 dedicated graphics memory. After a week, i got the firs blue screen error after which it couldn't boot [i couldn't even get to BIOS).
I was out of the country, so my friend called the service staff who told him to try to run some tests, that time it worked, he got to BIOS, ran the tests, everything was fine and the laptop started up normally. Now, 2 weeks after, I'm getting blue screens continuously, and laptop won't boot. If it boots [and it usually happens when you hit it slightly, though, i don't know if it's a conincidence], windows 7 starts up normally and everything is working fine until the next blue screen shows up, which disables my laptop all over again.

Blue screen looks like this:

BAD_POOL_CALLER

Technical information:

STOP: 0x0000000C2 (0x00000099, 0xFE8F40DC, 0x00000000, 0x00000000)
Collecting data for crash dump
Initializing disk for crash dump
Beginning dump of physical memory
Dumping physical memory to disk:100

Is it a software crash? Can I run Win 7 repair if I manage to boot it and how to do that? Is it my hard disk problem?
What to do? -.-
