The ASUS power adapter is below spec and it may damage the adapter because the HP is drawing 45 W more power than it can deliver and will cause it to overheat.
The 17" HP requires 18.5 or 19 volts depending upon the model of the HP laptop (check the power requirements on the label on the bottom of the laptop). If the ASUS adapter doesn't deliver this voltage, it most likely won't power up the HP laptop.
Use the power supply/adapter from the other 15" HP. If this HP's adapter has a voltage output of 19 volts and the 17" laptop requires 18.5 volts, don't worry a voltage difference of 0.5 volts, the only problem is whether the power plug will fit into the power socket of the 17" HP laptop.

Depending upon your BIOS manufacturer, generally this POST error code means either a video card problem or a motherboard problem. If the RAM is OK then you have a motherboard problem, and this may not be cost effective to fix. Consider putting your money towards a new laptop, remove the hard disk and put it into an external USB adapter case and use it as an USB hard drive for backup etc.

Is there a blue light to show that the wireless is active on the laptop? If not, switch the wireless connection on once windows has loaded. It may be that you have a faulty connection between the wireless card and the motherboard. Check out this link:

and follow the instructions

crashes, as in locks up? What kind of video memory or card you have? And, how do you have it optimized(faster performance, most likely)? This takes a bit of 'tweaking' to get just right.

sounds like faulty graphics card

Doesn't sound real good. Probably the LCD panel or driver chip. The chip is normally a part of the mother board. You might want to try reseating the LCD screen cable on both the LCD end and the motherboard end. That may resolve the problem. If not, try plugging in and external monitor. If you get a good display on that, you probably have a bad LCD, although there is still the possibility of the motherboard being bad.. If you don't get a good display on the external. you have a bad motherboard.

This may not strictly be a laptop computer question, but it sounds like the belt drive on the drum has broken or come off. This is a common problem. If you are handy, unplug the machine, turn it around, and remove the sheet metal screws on the back holding the back panel on. Remove that panel and look for broken or unseated belts. If you find broken or unseated belts, replace them with new ones. If you do not, you need to call in professionals or buy a new washer. Or find someone more handy to help. :>)

Do you have a firewall installed? If so, disable it and see if that helps. Try a system restore, Start, programs, accessories, system tools, system restore. It will give you a list of dates to restore to. Put the latest date that you knew that you had a working connection.

delete and reinstall your email software.

It depends what program you used to add it in the first place. Open the software and look for settings, or just uninstall it.
