HP Compaq Presario CQ57, Windows 7 Home Premium SP-1 64 bit
A month ago I bought an HP Compaq Presario CQ57 notebook (laptop), which comes installed with 2 x 1GB RAM modules. It functioned fine. A couple of weeks ago, I upgraded the RAM by replacing one of the 1GB modules with a 4GB one.
When I restarted Windows, yes, it did blue screen momentarily, but recovered with another start and then things went well for a week.
Then, upon attempting to reboot, it failed. On the Windows Welcome screen, it flickers briefly before it fails and goes to a blue screen.
Using the HP Recovery Console, after trying a recovery that didnít work, I tried the option of restoring to factory condition. Then, it still produced blue screens, giving error messages like IRQL less than equal and Page fault in non-page area.
I replaced the new RAM with the original 2 x 1GB RAM and tried a restore to factory condition option again. This time it worked. However, the hard drive partitions are odd.
As you can see, Disk 0 is divided into
System 199 MB, C 75GB, not labled 133.34 GB, Recovery D 19.38, HP TOOLS E 3.97 GB.
Ignore the CD ROM below.
Isnít System supposed to be on C? And the 133.34 GB unallocated space isnít supposed to be there either.
I ran the restore to factory again and it produced the same disk partitioning. I consulted HP customer service, and they sent me a Windows disk and wants me to try restoring from that rather than from the Recovery provided on the hard drive. I havenít done this yet, but is there an explanation? And actually, canít I simply expand the C partition to the unallocated space to the right?
